Tomcat doesnt seem to be working
« on: July 14, 2008, 09:41:06 PM »
I installed tomcat following the instructions in http://wiki.contribs.org/Tomcat, but it does not seem to be working.  I cannot access http://mysite:8080, and a site I installed in an ibay has servlets that do not work.

I placed the necessary war file in tomcat/webapps

config show tomcat results in:
tomcat=service
    TCPPort=8080
    access=public
    status=enabled

Where do I start to troubleshoot?

What does /var/log/messages say? Any clues especially around the time you issued this command?

Start with this command...

[root@sme ~]# /opt/tomcat/bin/startup.sh

And view the logs in...

/opt/tomcat/logs

This gives me the following ourput:

And you still did not provide any information on the contents of /var/log/messages? Perhaps there are some clues there (especially when starting the service)...

It seems there are problems with the tomcat user/group... perhaps this might be the cause. I also do not see that you are starting the service... did you already do try to start the service?

On the user/group, these lines from the wiki/howto:

give me back the following:

[root@cmenl ~]# groupadd tomcat
groupadd: group tomcat exists
[root@cmenl ~]# useradd -g tomcat -d /opt/tomcat tomcat
useradd: user tomcat exists

As for starting the service doesn't /etc/rc.d/init.d/tomcat do that?

I tried doing this:

 /bin/su $TOMCAT_USER $TOMCAT_HOME/bin/startup.sh

and got this...
/bin/su: user /bin/startup.sh does not exist

So you created the user at a later stage, seems OK.

Yes but not by only adding the (sym)link.

That is because most likely the $TOMCAT_USER and $TOMCAT_HOME are set in the script and not known on the CLI. Why don't you just try the commands in the wiki, it states even in bold:
Quote from: http://wiki.contribs.org/Tomcat
Make startup script runable and make tomcat start automatically at boot
Which means reboot and the service should be started... did you already try that? Perhaps this will work as well, although I can not test it:
Code: [Select]
service tomcat start

Had done this right from the start - following the wiki...

And... what is the result when you try to access the server? This does not say much to me other than that it seems to be starting, but I have no way of testing this as I do not have it installed.

 I guess, as you said you already rebooted, the symlinks, that should start tomcat at boot time, might not be correct... provided that you can access your tomcat server now after manually starting it...

The only changes I made from the wiki was..

Create the tomcat user via the server-manager

Gave the tomcat user access to a shell but with no password set.

Prior to doing the above it appeared that JAVA_HOME wasn't being set.

I really don't think creating users and groups at the command line using regular linux tools is a good idea with smeserver.

$TOMCAT_USER and $TOMCAT_HOME are variables that have to be set to some value before you use them.

In the init script, they get set to tomcat and /opt/tomcat respectively.

So, to expand out that line like the script would you need to type

/bin/su tomcat /opt/tomcat/bin/startup.sh

Tried creating tomcat user in server-manager, but it wouldn't allow me.  It came back with an error message saying that a system user by the same name already exists.  I took that to mean that the tomcat user I created from the wiki was already there...

When I do that I get the following:

Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program

It should be defined in the script... you did create the script as stated in the wiki, did you? Or are you just trying to execute lines from that on the command line? If you did not create the script I think we have the reason that your tomcat server is not starting at boot time.

I am still wondering if you are following the HowTo to the letter as other user(s) have had no problems getting it to run with the instructions stated there.

I followed it absolutely to the letter...

The script I created was cut and paste from the wiki - as below:
#! /bin/bash
#
# tomcat Start the tomcat server.
#

NAME="Jakarta Tomcat 6"
TOMCAT_HOME=/opt/tomcat
CATALINA_HOME=/opt/tomcat
JAVA_HOME=/usr/java/jdk
CATALINA_OPTS="-Dfile.encoding=iso8859-1"
TOMCAT_USER=tomcat
LC_ALL=en_US
export TOMCAT_HOME CATALINA_HOME JAVA_HOME CATALINA_OPTS TOMCAT_USER LC_ALL
cd $TOMCAT_HOME/logs
case "$1" in
  start)
    echo -ne "Starting $NAME.\n"
    /bin/su $TOMCAT_USER $TOMCAT_HOME/bin/startup.sh
    ;;

  stop)
    echo -ne "Stopping $NAME.\n"
    /bin/su $TOMCAT_USER $TOMCAT_HOME/bin/shutdown.sh
    ;;

  *)
    echo "Usage: /etc/init.d/tomcat {start|stop}"
    exit 1
    ;;
esac

exit 0

Is there an easy way to start-over???

Comparing this post of you to the results shown in this post of william_syd I think it is starting fine as the output looks more or less the same.

That still leaves the issue why you can not access it. Does tomcat have errorlogs as well? Perhaps a clue might be in there.

After you have started it does it stay up? Try this a few times after starting the service:
Code: [Select]
ps aux | grep tomcatAbove should at least output all process run as the tomcat user under which the process should be started judging from the script.

If not it seems it does not stay up... otherwise it should be up and accessible. Did you try and access it from your server itself already?
Code: [Select]
elinks http://localhost:8080

This is from the only file in the tomcat log directory (catalina.out):
/opt/tomcat/bin/catalina.sh: line 273: /usr/java/jdk/bin/java: is a directory
/opt/tomcat/bin/catalina.sh: line 273: /usr/java/jdk/bin/java: is a directory
/opt/tomcat/bin/catalina.sh: line 273: /usr/java/jdk/bin/java: is a directory

From the cli, remove the tomcat user and group.

Then...

Code: [Select]
Go into server manager and create a user named tomcat

chown -R tomcat:tomcat /opt/tomcat/

chmod 770 /opt/tomcat/

db accounts setprop tomcat Shell /bin/bash

signal-event user-modify tomcat

Wouldn't this do as well (although your method might be preffered as you have the user displayed in te server-manager as well)?
Code: [Select]
usermod -s /bin/bash tomcat
