Installing Tomcat 6 on Ubuntu

If you are running Ubuntu and want to use the Tomcat servlet container, you should not use the version from the repositories as it just doesn’t work correctly. Instead you’ll need to use the manual installation process that I’m outlining here.

Before you install Tomcat you’ll want to make sure that you’ve installed Java. I would assume if you are trying to install Tomcat you’ve already installed java, but if you aren’t sure you can check with the dpkg command like so:

dpkg –get-selections | grep sun-java

This should give you this output if you already installed java:

sun-java6-bin                                   install
sun-java6-jdk                                   install
sun-java6-jre                                   install

If that command has no results, you’ll want to install the latest version with this command:

sudo apt-get install sun-java6-jdk

Installation

Now we’ll download and extract Tomcat from the apache site. You should check to make sure there’s not another version and adjust accordingly.

wget http://apache.hoxt.com/tomcat/tomcat-6/v6.0.14/bin/apache-tomcat-6.0.14.tar.gz

tar xvzf apache-tomcat-6.0.14.tar.gz

The best thing to do is move the tomcat folder to a permanent location. I chose /usr/local/tomcat, but you could move it somewhere else if you wanted to.

sudo mv apache-tomcat-6.0.14 /usr/local/tomcat

Tomcat requires setting the JAVA_HOME variable. The best way to do this is to set it in your .bashrc file. You could also edit your startup.sh file if you so chose.

The better method is editing your .bashrc file and adding the bolded line there. You’ll have to logout of the shell for the change to take effect.

vi ~/.bashrc

Add the following line:

export JAVA_HOME=/usr/lib/jvm/java-6-sun

At this point you can start tomcat by just executing the startup.sh script in the tomcat/bin folder.

Automatic Starting

To make tomcat automatically start when we boot up the computer, you can add a script to make it auto-start and shutdown.

sudo vi /etc/init.d/tomcat

Now paste in the following:

# Tomcat auto-start
#
# description: Auto-starts tomcat
# processname: tomcat
# pidfile: /var/run/tomcat.pid

export JAVA_HOME=/usr/lib/jvm/java-6-sun

case $1 in
start)
        sh /usr/local/tomcat/bin/startup.sh
        ;;
stop)  
        sh /usr/local/tomcat/bin/shutdown.sh
        ;;
restart)
        sh /usr/local/tomcat/bin/shutdown.sh
        sh /usr/local/tomcat/bin/startup.sh
        ;;
esac   
exit 0

You’ll need to make the script executable by running the chmod command:

sudo chmod 755 /etc/init.d/tomcat

The last step is actually linking this script to the startup folders with a symbolic link. Execute these two commands and we should be on our way.

sudo ln -s /etc/init.d/tomcat /etc/rc1.d/K99tomcat
sudo ln -s /etc/init.d/tomcat /etc/rc2.d/S99tomcat

Tomcat should now be fully installed and operational. Enjoy!

    I think another part of this install (probably for any app that generates logs) is to add an entry to logrotate. Otherwise you get gobs and gobs of logs, especially on a production machine. Don’t ask me how I know this. I just know it. (/me hangs head in shame)

    How about an article about logrotate?

  2. The Geek

    Great suggestion! Will add it to the queue…

  3. steve meeks

    Thanks for the how to: It worked flawlessly, and I just upgraded to Gutsy Gibbon last night. For some reason, I hadn’t been able to get Tomcat to work for awhile now, and I found this article today. Thanks again. If it weren’t for people who go out of there way to share this kind of knowledge, I would have never discovered the wonderful world of Linux and Open Source technology. Thanks again.

    Hi there, thanks for your great tutorial. But I am having a little problems.

    1. NoClassDefinition: When I want to shutdown tomcat. It always gives me that error. But when i startup there are no problems at all.

    2. After I followed all your instructions. How do I know if the installation works? I tried moving to http://10.0.106.21/ (which is the IP address of the server), Tomcat does not seem to load, I got a 404 error. Any idea why is this so?

    Thanks
    aaron

  5. Seth

    @aaron:
    1. Does it say which class it can’t find? Can you post your full stacktrace? That’ll help track down the problem.

    2. Try http://127.0.0.1:8080 to view it after it’s running. It doesn’t run on port 80 by default.

  6. Dan

    I have the same problem that Aaron has. JRE and JDK are installed and the variables are set.

    ~ sudo /opt/apache-tomcat/bin/catalina.sh run
    Using CATALINA_BASE: /opt/apache-tomcat
    Using CATALINA_HOME: /opt/apache-tomcat
    Using CATALINA_TMPDIR: /opt/apache-tomcat/temp
    Using JRE_HOME: /usr/lib/jvm/java-6-sun
    Exception in thread “main” java.lang.NoClassDefFoundError:

    I don’t know how to get full stacktrace. Any help is much appreciated.
    Dan

  7. Seth

    You logs should be in /usr/local/tomcat/logs/ if you used the directions above. Looks like yours will be in /opt/apache-tomcat/logs.

    There should be a file named localhost.YYYY-MM-DD.log in there (where YYYY-MM-DD is the year, month, day respectively).

    Peruse that file and there should be a stack trace in there.

    If there isn’t, do the following from the command-line:
    > cd /opt/apache-tomcat/logs
    > grep -l Exception *.log

    That should list all the files that have a stack trace in them. Look at those files and it should say where the error is occuring.

    HTH,
    SETH

  8. Dan

    Thank you for your help but i can’t find any of these log files.
    The folder /opt/apache-tomcat/bin/log/ is empty and in /opt/apache-tomcat/logs/ is only one file catalina.out. In catalina.out is only one line Exception in thread “main” java.lang.NoClassDefFoundError:
    Is there a way get more information out of tomcat. That stacktrace, if that is one, seems not very helpful.

    Dan

  9. Seth

    Weird. It’s not even finding the Bootstrap class to start Tomcat. I thought the error was happening further down the chain.

    Add the following line to catalina.sh:

    echo “CLASSPATH: $CLASSPATH”

    it should go around line 232 after the “run” command check

    elif [ "$1" = "run" ]; then
    shift;
    ### NEW COMMAND ON NEXT LINE
    echo “CLASSPATH: $CLASSPATH”

    Send the output along. That’ll help find the problem.

  10. Dan

    I got the following line
    CLASSPATH: :/opt/apache-tomcat/bin/bootstrap.jar:/opt/apache-tomcat/bin/commons-logging-api.jar
    The bootstrap.jar is where it suppose to be but the commons-logging-api.jar is nowhere to be found on my system. Can this cause the problem?

  11. Seth

    Not having the commons-logging-api.jar shouldn’t matter unless you’ve configured something from the default.

    What happens when you run:

    javap -classpath “/opt/apache-tomcat/bin/bootstrap.jar” org.apache.catalina.startup.Bootstrap

    It should print out the methods of the class.

  12. Dan

    That works.

    ~ javap -classpath “/opt/apache-tomcat/bin/bootstrap.jar” org.apache.catalina.startup.Bootstrap

    }

  13. Dan

    I downloaded Tomcat 5.5 and it works just fine right out of the box. That is weird.

  14. Dex

    Thanx man…i tried Tomcat6.0.14 with above instruction.It worked 100%

  15. Jose C. Lacal

    Great article. Some additional pieces of the puzzle:

    chmod +x ./bin/*.sh

    Error messages such as this are fixed with the above command:
    “The BASEDIR environment variable is not defined correctly”

    And Tomcat 6.0.14 runs on :8080 and not :8180

  16. Didik Susilo

    I’ve tried this tutorial to Xubuntu 7.10 with apache2.
    It’s working….100%
    This is a great tutorial…..thanks

  17. llsutherland

    I’m a newbie to Linux. This article was excellent! Thank you.

  18. Fred

    Hey guys – cool howto, but one question remains – now tomcat starts as root. How can i change it to let it run as different user?

  19. Gustavo

    tomcat is runing ok, but, i cant open http://localhost:8080/manager/html, how to configure tomcat’s users?

  20. Jörgen Persson

    Thanks for the article.
    Haven’t tried i yet but I’m sure it works. I have a question though.

    How do you set up two different tomcats, e.g. one dev and one prod, on the same computer to autostart? Is it just do create two different scripts in init.d? Like tomcat-dev and tomcat prod and have them point to their respective environments?

  21. Jörgen Persson

    Gustavo, in CATALINA_BASE/conf/tomcat-users.xml, add the following lines

    restart tomcat and launch http://localhost:8080/admin

  22. Jörgen Persson

    hmm, the lines were removed when posting, trying again

    <role name=”admin”/>
    <user name=”admin” password=”deep_dark_secret” roles=”admin”/>

  23. Erik Alm

    Thanks for the article!

    However, instead of creating the symlinks by hand you should take a look at “update-rc.d”…

  24. Kevin

    How would I unstall it?

  25. Terry

    “you should not use the version from the repositories as it just doesn’t work correctly.” -= all very well when you wrote this. Please note this article was written in October of 2007. Ubuntu is ever being updated. new release is out, Hardy Heron 8.04 !
    Maybe this Tomcat you speak of will work now.

  26. The Geek

    @Terry

    Good point… I’m going to test that out and see if the repo version works correctly. This guide is still relatively useful if you wanted to do a manual install, of course.

  27. Mark

    @Terry

    The default installation of Tomcat5.5 from the repos in 8.04 is borked. I followed the instructions above and have TC6.0.14 running perfectly thanks to The Geek :)

  28. The Geek

    @Mark

    Thanks for testing that out, I hadn’t had a chance… glad it worked for you :)

  29. Michel

    Hi,

    Thanks for the howto – very straightforward and pretty idiot -proof, which doesn’t say much for me as I have a slight problem :)

    I set everything up, and all went well. I had cause to restart my machine over the weekend, and tomcat started automatically, great stuff so far. The problem occurs when I need to restart Tomcat having updated classes. The log files are created using the ‘root’ user (so owner and group is root), so I get a ‘permission denied error when tomcat tries to access them if my normal user executes the ./shutdown script.

    Can you tell me how to change things so that, when starting the machine, tomcat runs under the regular user, rather than under root? Or is that not a good idea?

    Thanks,

    Michel

  30. Michael Mrozek

    The argument to dpkg in the first step should be –get-selections (two dashes)

  31. Abhi

    Tomcat is not starting automatically even I followed the last steps necessary for making it starting at startup.I have to manually starting it up.

  32. me

    I have the same issue like Abhi and it runs under root, which I don’t like.

  33. MarioFromBelgium

    Hi,

    I’m struggling with setting up TOMCAT 6 for more than two months now …no succes.
    I have reinstalled UBUNTU from scratch, installed java and tomcat but it always gos wrong when I want to startup TOmcat. I have followed al the howtos tutorials forums in the net.
    2 questions:
    1° does it matter when I installed apache at UBUNTU-installation? Should I maybe chose a clean UBUNTU install and add apache-tomcat (and MySQL) later.
    (PS. apache is running after UBUNTU LAMP instalation)

    2° if that doesn’t matter how can it be that when $echo JAVA_HOME returns a correct value … that sh startup.sh in most case tells me that JAVA_HOME or JRE_HOME is not set. Actually without changing anything wuring my session I have seen succesfull startups (that is without above mentioned error message) but with the following error message : can’t touch CATALINA_HOME..pathegoeshere…/logs permission denied.

    In any case the result is the same …nothing on http://serverIPadress:8080

    (If I don’t get it to work before 15 june I will need to migrate (back) to Windows…no problems there!)

  34. Andrius

    OK, so I did install Tomcat and it worked but…

    The autostart part is not correct because Tomcat behaves differently when it autostarts.
    More specifically Tomcat (or Java fails) converts all non-ascii characters to “?” when accessing anything on the file system. It will be impossible to open file “/home/user/ąuolas.png” from any servlet as Tomcat (or Java) will look for file named “/home/user/??uolas.png”.

    What is interesting is that once you restart Tomcat (sudo /etc/init.d/tomcat restart) everything will work fine. I do not know much about Linux internal workings but i looks like Tomcat is started before system locale is set. Unfortunetly I do not know how to fix this. Maybe somebody can help with this?

  35. Hamid

    hi every body
    thanks for the cool how to.
    I followed up every single step. but it seems so wierd for me :
    I opened firfox and put “http://localhost:8080/ and I got 401 Page not found error, bassically I expect the homepage of the tomcat installation

    but if tried the following linke http://localhost:8080/manager/html
    I get a login dialog box asking for a user name and password, what should I put here?
    looking forward to your help

  36. Amos

    FYI: On hardy (8.04) at least, you can run the following command after creating your tomcat startup script in /etc/init.d in order to put links in the right spots.

    update-rc.d tomcat defaults

  37. yeswanth kumar reddy .o

    tomcat is runing ok, but, i cant open http://localhost:8080/manager/html

  38. Thomas

    8.04 server seemed to work pretty well. I was able to get it going by following some directions here…

    http://blixtra.org/blog/2006/07/14/setting-up-tomcat-5-on-ubuntu-606/

  39. john

    I changed up all uses of “vi” to “sudo gedit” cause I am too newbie to be comfortable with vi, and I was having permissions problems.

    had a moment of fear that I screwed up when I went to http://localhost/ but read the RUNING.txt and realized I should use http://localhost:8080/

    thanks for the step by step!

  40. Olaf

    Hi there,
    nice article, but it leaves one nasty thing open, just as “me” already noted: Tomcat will run as root if you use your script, which is “working”, but not “what you want”.
    Instead, make sure, the unprivileged user “tomcat” (or whatever you like) exists and start it using
    sudo -u tomcat sh /usr/local/tomcat/bin/startup.sh

    You might want to chown temporary directories prior to that, especially if you already ran tomcat as root:
    cd /usr/local/tomcat/
    chown -R tomcat webapps temp logs work conf

    Actually, I don’t particularly like opening the conf directory for tomcat, but sometimes tomcat prefers to write to its configuration… You don’t need webapps to belong to tomcat if you dont autodeploy, but you definitely need logs and work.

  41. Al

    Unlike Mark, I get the same issue as Mario:
    startup.sh says that “Neither the JAVA_HOME nor the JRE_HOME environment variable is defined”, but when I enter “echo $JAVA_HOME” or “echo $JRE_HOME” I get “/usr/lib/jvm/java-6-sun”
    (Ubuntu 8.04 64bit, Tomcat 6.0.14)
    But unlike Mario, I can not migrate back to Windows. I’m dead in the water…

  42. Al

    …so now I’m “undead”?

    Regarding Tomcat’s inability to see the enviroment’s JAVA_HOME variable: here’s what worked for me:
    http://ubuntuforums.org/showthread.php?t=819451&page=2

  43. Felipe Andrade

    Problems!

    I can’ t set CLASSPATH!!

    I’ve tried many ways, but nothing has worked for me.

    $ javac -classpath “/usr/loca/tomcat/lib/servlet-api.jar” HelloWorldExample.java
    HelloWorldExample.java:23: package javax.servlet does not exist
    import javax.servlet.*;
    ^
    HelloWorldExample.java:24: package javax.servlet.http does not exist
    import javax.servlet.http.*;

    I’ve tried to put this classpath in “etc/profile”, in “~/.bashrc”, to load it in a sh script at init.d…

    Tomcat works fine under netbeans 6.1, compiling, etc. It just happens on bash.

    Any Ideas?

  44. teena

    Hi I followed all the steps but i wasn’t able to find the /etc/rc2.d/S99tomcat. I dont have this file. i created everything else mentioned here. im stuck here and i have been trying desperately to install tomcat on my ubuntu7.10 laptop. could any one lend any help, please?

  45. Amos

    Hi Teena. You must have missed the very last step, which was to create the symbolic link you are asking about using the “sudo ln” command. Have another look at the instructions.

  46. teena

    Hi Amos,
    when i tried to create that last step i got the error saying the S99toimcat file/directory cant be found.
    this is the only step im having problem with. i did all the steps correctly.

    Thanks,
    Teena

  47. Amos

    Hi Teena. The last step is:

    sudo ln -s /etc/init.d/tomcat /etc/rc2.d/S99tomcat

    which *creates* the S99tomcat link to the /etc/init.d/tomcat file you created in an earlier step. I have no idea how running that command as written could create the error you are describing. Even if neither of those files existed, the command would still run and create the link to a non existent file. Are you sure you are typing in the command “ln” and not “ls”? Did you try copying and pasting that whole line off the page into your terminal?

  48. teena

    Dear Amos,
    I installed Tomcat 6.0.14 on my Ubuntu7.10 yesterday after a lot of struggel :)
    Thanks so much for your support. I didnt actually execute the last step this time. since im a newbie to linux, i made many mistakes while installing tomcat. i think its not necessary to create these symlinks if i do not want to start the server automatically at start up.

    Thanks a lot,
    Teena

  49. Amos

    Congrats Teena. It’s not as nice and easy a process as it could be, that’s for sure. Startup scripts seem to be the achilles heel of server applications that aren’t packed for a particular distribution. So many must get written and customized for particular distributions but so few seem to get submitted back for inclusion in the core distributions.

  50. Erik

    Hello,

    Tomcat does not work well when installed from the repository, that’s true, but the fix for this is not too complicated (at least if you insist on using the package):

    First install the package (note that you should match your tomcat version with your java version, and I’ve not come around to update my server, so this pertains to java 5 with tomcat 5, however I suspect the procedure for fixing tomcat 6 with java 6 should be similar to this).

    In the file /etc/default/tomcat5 uncomment and set up JAVA_HOME (see above for the path, but note that if you do not use java 6 and tomcat 6 you should change it to look something like “/usr/lib/jvm/java-1.5.0-sun”), also make sure the following line is uncommented (in the same file):

    TOMCAT5_SECURITY=no

    This will turn off jaas-security. This is what makes tomcat impossible to use out of the box.

    You may also wish to set up the -tag since it’s set up, per default to open tomcat at port 8180. You do this in /etc/tomcat/server.xml like this (note the port-attribute, and the number, you can probably alter the existing -tag, just make sure you have the right one — check the comment!):

    That way you should get tomcat 5 from the repositories to work. I’m guessing jaas is turned on as some kind of precaution against getting sued or something, and why the JAVA_HOME variable isn’t reflected by the update-java-alternatives command is beyond my understanding.

    Cheers!

  51. Erik

    P.S. I foolishly used XML syntax for describing the update of the server.xml file. (I’ll give it another try):

    You may also wish to set up the Connector-tag since it’s set up, per default to open tomcat at port 8180. You do this in /etc/tomcat/server.xml like this (note the port-attribute, and the number, you can probably alter the existing Connector-tag, just make sure you have the right one — check the comment!):

    <!– Define a non-SSL Coyote HTTP/1.1 Connector on port 8080 –>
    <Connector className=”org.apache.coyote.tomcat5.CoyoteConnector”
    port=”8080″ minProcessors=”5″ maxProcessors=”75″
    enableLookups=”true” acceptCount=”10″ debug=”0″
    connectionTimeout=”20000″ useURIValidationHack=”false” />

    That way you should get tomcat 5 from the repositories to work.

  52. Erik

    By the way, you may also want to check the update-rc.d command in Debian/Ubuntu, with it you can make the init-script set up automatically. Unfortunately not the actual script, but the linking and such.

  53. Breen

    Hello,

    I followed your instructions (thanks for doing this) and was able to install Tomcat 6.0.18 on Ubuntu 8.04 to the point where I get the index.html page displayed when I go to http://localhost:8080 . However, it seems none of the relative links are reachable from the top level page (e.g. http://localhost:8080/docs). It just spins waiting for localhost until it times out.

    $CATALINA_HOME is set to /usr/share/tomcat (as is $CATALINA_BASE, by default), but if /usr/share/tomcat/webapps/ROOT is the root directory where the index.html page is found, one would expect http://localhost:8080/docs to resolve to the path /usr/share/tomcat/webapps/ROOT/docs . However, the docs directory is to be found at /usr/share/tomcat/webapps/docs .

    Can someone please tell me what I need to do to fix this and complete the installation?

  54. StunningNikon

    Hi,

    It was a great thing to setup Tomcat6.0.18 on my Ubuntu Machine. Thats a lot for this awesome documentation.
    I ran startup.sh from the /usr/local/tomcat/bin folder. The below are the outputs which I was getting.

    nikon@Stunning:/usr/local/tomcat/bin$ ls start*
    startup.bat startup.sh
    nikon@Stunning:/usr/local/tomcat/bin$ startup.sh
    bash: startup.sh: command not found
    nikon@Stunning:/usr/local/tomcat/bin$ ksh
    $ startup.sh
    ksh: startup.sh: not found [No such file or directory]
    $ ls -l startup.sh
    -rwxr-xr-x 1 nikon nikon 1956 2008-07-21 20:01 startup.sh

    I was able to http://127.0.0.1:8080/ get this page loaded. “If you’re seeing this page via a web browser, it means you’ve setup Tomcat successfully. Congratulations!” Not sure how this came as the startup.sh didn’t work correctly.
    I tried clicking on the Admistration/Status http://127.0.0.1:8080/manager/status. It said Page Load Error (Firefox can’t establish a connection to the server at 127.0.0.1:8080.)

    Can anyone help me on this.
    Out of curiosity, I installed Ubuntu and Java/Eclipse and wanted to install Tomcat and the mySQL too.

  55. SMut

    The howto’s okay and the startupscript is okay, but the tomcat’s running on port 8080 and does not interact with – for example – an existing Apache 2, no logrotation and so on…
    Maybe I’ll write a howto about those issues next.

    @stunningnikon: you can’t start a shellscipt by typing it’s name as long as the script does not reside in a directory which is in the path of your shell you are using. The correct syntax of starting scripts is /path/to/the/script/shellscript.sh
    If you are ‘sitting’ in this directory type ./shellscript.sh or bash shellscipt.sh – however…
    What the hell are you trying to install Tomcat, Java/Eclipse and MySQL for?
    Just try to learn basics first, Java is an extremly hard entry point if you want to start hacking, in my opinion.

    Steffen

    tar xvzf apache-tomcat-6.0.18.tar.gz
    of course using tab key you dont have to change all of that…
    sudo mv apache-[tab] /usr/local/tomcat

    I know in Zope for instance you have to create a user called zope and give it rights to its own directories, Never use ROOT to do zope’s job (run scripts etc.) So in case of tomcat may be there should be a user admin who haws rights to tomcats files/folders?

    I am not really sure about that!?

    thank you for the tutorial,

    but there is a small error :
    it should be
    dpkg –get-selections | grep sun-java
    instead of
    dpkg –get-selections | grep sun-java

    Note that tomcat6 is now available as an official Ubuntu package (starting from 8.10 release) so this whole howto could be replaced by “sudo apt-get install tomcat6″.

    After setting up tomcat. this is what i get on start up
    Using CATALINA_BASE: /usr/share/tomcat6
    Using CATALINA_HOME: /usr/share/tomcat6

    sorry am new to apache. how do i solve this

  61. anix

    be sure that you have a directory /usr/share/tomcat6;
    if you have this directory, you can try to make the directory logs under /usr/share/tomcat6 by
    mkdir /usr/share/tomcat6/logs

  64. aden

    I have to install Tomcat as a part of a Tafe assignment but I don’t really know anything about it so how do I test to see if it is running. I tried ps -A but I can’t see any process named tomcat or anything similar.

  65. Kamal

    Thank you very much for writing this, I was able to follow the instructions and get it setup in a few minutes. One thing that might be worth adding is the need to enable multiverse repository (for installing sun-jdk6)

  67. gettica

    I am running tomcat6 on ubuntu which I downloaded as part of bitnami’s redmine stack. When I go to 127.0.0.1:8080, Tomcat’s welcome pops up. The docs & examples are loaded correctly. I added a “manager” and an “admin” to the tomcat-users.xml file as instructed. I restarted tomcat6 and I am still unable to log in to either the manager webapp or the host-manager webpapp with the user ID and password that I entered into tomcat-users. It gives me a continual loop of requesting the id and password until I hit cancel. Help!

  68. pcs305

    gettica,

    Make sure you removed the comments from the tomcat-users.xml file.
    (remove the on the line before the statement.

    Hi there,
    It just worked. Precise instructions particularly to me :)

  71. Risto

    Hi,

    I’m trying to run a Java web application on localhost. Op sys: Ubuntu, Tomcat 6.0.
    I installed tomcat 6.0 under /usr/share/tomcat6 and tried to direct /etc/init.d/tomcat6 (as far as I know this is what starts the tomcat on startup) to start the tomcat from /usr/share/tomcat6/bin.

    When I start my computer the tomcat runs and I can see default page, but when I try to vist my app page I get Nullpointer on MySQL connection close().
    But if I shutdown tomcat (using /etc/init.d/tomcat6 stop) and restart the tomcat directly from /usr/share/tomcat6/bin startup.sh. Then everything works fine.

    So basically with command “/usr/share/tomcat6/bin/startup.sh” I can see my app, but with command “/etc/init.d/tomcat6 start” I can’t. Allthough both of them start tomcat.

    I want that I can see my app right after computer stars (so I don’t manually have to start tomcat).

    Can anybody help?

    Regards,
    Risto

  72. Risto

    Already got it fixed.

  73. joja

    flawless! thank you :D and you are just very correct about not installing from ubuntu archives, they screw the manager and the host-manager..

  74. sid

    hey the option for dpkg is –get-selection which is
    (double hyphen)get(single hyphen)selection
    do you think you guys can make it more clear?

    enjoying your site a lot-pretty useful, thank you!

  75. marius

    Do you know if runlevels have changed in Jaunty? I cannot get the script to start automatically, even though it’s been working fine in previous versions. It starts fine in a terminal, just not on computer startup.

  76. kinglok

    I can’t agree olaf no more. He really saves my life in starting up tomcat as unprivileged user.

    What’s more I start up tomcat by using djb daemontools, here comes the commands and scripts:

    useradd tomcat -g nogroup -d /java/tomcat6/ -s /bin/false -p’*’ -r
    useradd tomcatlog -g nogroup -d /tmp -s /bin/false -p’*’ -r

    cd /java/tomcat
    chown -R tomcat webapps temp logs work conf

    mkdir -p /var/service/

  77. Bucky24

    I am not sure if this has been covered in an earlier post, but the way given to set up the tomcat-users.xml file did not work for me.

    This did, however:

    The role tags were added automatically when I restarted the server, but I don’t know if this will happen for everyone, so I am leaving them in.

    -Bucky24

  78. Bucky24

    it left out the xml tags….

  79. Bucky24

    Oh well, I can’t get it post the tags…

    Whoever is using Netbeans IDE on Ubuntu, don’t try to install Tomcat6 that comes with Netbeans distribution! This is the right way to install Apache-tomcat6. Thanks to the author!

  81. Alberto

    It took me forever to find the answer to fix autostart on ubuntu 9.04.

    Here it is:

    1. First remove old symlinks with sudo update-rc.d -f tomcat remove

    2. Execute the follwoing: sudo update-rc.d tomcat start 99 2 3 4 5 S . stop 0 1 6 .

  83. Tudor

    Isn’t Tomcat in the repositories? I’m using Jaunty and a simple sudo-apt get install tomcat6 did the job for me!

  84. vikitor

    Thank you very much!, This how to has proven to be extremely useful.

  85. Luca

    Hi, thank’you very much for this tutorial.
    It saved my life! I had some jsp apps connecting to a MySQL db that just did not work with tomcat6 package from ubuntu repos!!! Now they work flawless! This also applies to Karmic, not just to Jaunty.

    Just for my curiosity: is tomcat6 from ubuntu a free implementation of tomcat 6 specifications or it is just the official apache tomcat app packaged for ubuntu?
    If not, wouldn’t be a good idea to create a ppa for the latest Apache Tomcat 6 from official site?

  86. Weeber

    Wow alberto, I needed that link too. For some reason tomcat wouldn’t even start manually installing it the way described here but with your link to ubuntuforums it autostart and everything thanks! My ubuntu version is 9.04.

  87. Weeber

    Also, from the ubuntuforums: “it took me days, but I finally realized that tomcat will only start during boot if the startup script is in /etc/rcS.d .. When the start-up script is in /etc/rc2.d – The script doesnt give any errors, and the tomcat logs do not indicate any problems .. its like the process just poofs.”

    Thank you very much. My pc died and I decided to switch to ubuntu on my new laptop. Installed myEclipse, but the tomcat6 wouldn’t work. I really appreciate making this information available. Did notice a few changes from tomcat5.
    thanks again.

  91. tsaid

    There’s a better workaround so you can keep Ubuntu’s Tomcat6 (taken from http://ubuntuforums.org/showthread.php?p=8541057, by DisDis)

    In a terminal:

    1. sudo apt-get install tomcat6
    2. cd /usr/share/tomcat6
    3. sudo ln -s /var/lib/tomcat6/conf conf
    4. sudo ln -s /etc/tomcat6/policy.d/03catalina.policy conf/catalina.policy
    5. sudo ln -s /var/log/tomcat6 log
    6. sudo chmod -R 777 /usr/share/tomcat6/conf

    sudo apt-get install tomcat6 cd /usr/share/tomcat6 sudo ln -s /var/lib/tomcat6/conf conf sudo ln -s /etc/tomcat6/policy.d/03catalina.policy conf/catalina.policy sudo ln -s /var/log/tomcat6 log sudo chmod -R 777 /usr/share/tomcat6/conf

    There. Now just go to Window/Preferences/Sever/Runtime Environments, add the Apache Tomcat6 Server and use /usr/share/tomcat6 as the installation directory!

  92. ghoyz

    my tomcat is configure but the default web directory is $CATALINA_HOME/webapps/ROOT/index.html
    i want to change the directory to $CATALINA_HOME/webapps cant someone help me tnx

  93. op

    you may read the tomcat documentation?

    webapps/ROOT/index.xhtml is actually the file you see when you dont use a context (http.//host/index.xhtml)

    this is the ROOT context.

    If you dont want to have it in webapps/ROOT you can place a ROOT.xml context file in tomcat/conf/Catalina/localhost/ROOT.xml and let tomcat know in which directory or .war file the root context resides.

    (just in case)

    so how do you start or stop the tomcat server?

  100. Scott

    Thank you! Your instructions were simple and worked flawlessly with Tomcat 6.0.29 on CentOS 5.4.

  101. zack

    Works fine!
    But Tomcat runs as”root”. How to run it under user “tomcat”?

  102. zack

    Ok, Googling is great!
    I found another script. It also works fine and starts tomcat using user tomcat. You just need to make sure you have a user “tomcat”.

    Cheers & have fun!

    You can fix that problem if you configure /usr/local/tomcat/conf/tomcat-users.xml file. You have to uncomment the next piece:

    I made some research on internet and forums but i didnt find an answer.

    So, somebody could help me it will be nice

    This file is needed to run this program

    me podrian ayudar cual es la causa por favor

  121. mario

    @Carlos Silva

    Hola Carlos. Lo que te ocurre es porque necesitas que los .sh tengan permiso de ejecución (-x). Para solucionarlo, puedes ejecutar el comando “chmod +x *.sh” estando en /apache-tomcat-6.0.18/bin/

    Un saludo.
    ———————–

    Hi Carlos. You need yo add execution perms to .sh files. To fix it you can execute command “chmod +x *.sh” being at /apache-tomcat-6.0.18/bin/

  122. michelle

    i am having problems properly setting JRE_HOME variable. i get this output:

    michelle@SQA-2:/usr/local/tomcat/bin$ sudo ./startup.sh
    [sudo] password for michelle:
    Using CATALINE_BASE: /usr/local/tomcat
    Using CATALINA_HOME: /usr/local/tomcat
    Using CATALINA_TMPDIR: /usr/local/tomcat/temp
    Using JRE_HOME: /usr
    Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar

    i feel like that line “Using JRE_HOME: /usr” should definitely have more to it…and i added this line to the end of .bashrc

    “export JAVA_HOME=/usr/lib/jvm/java-6-sun”

    logged in and out…did everything and i still get the same output when i try and run tomcat…any clue??

  123. michelle

    i just added a new file in tomcat/bin with the line “JAVA_HOME=/usr/lib/jvm/java-6-sun”
    now the output comes out but tomcat doesnt actually run…

    now any ideas??

    any help would be much appreciated

  124. al

    hi michelle,

    stop your tomcat service and you only need to add this line:
    JAVA_HOME=”/usr/lib/jvm/java-6-sun”
    JRE_HOME=”/usr/lib/jvm/java-6-sun”

    into /etc/environment.

    and check your tomcat/bin directory, if there’s setenv.sh file exist then you must also put this line below into setenv.sh file:
    export JAVA_HOME=/usr/lib/jvm/java-6-sun

    logout from that machine (reboot not needed) and run echo $JAVA_HOME it should be same as you defined above, tomcat is ready :)
