Topic: Tomcat doesnt seem to be working

[EastEnder01]

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?

[cactus]

Where do I start to troubleshoot?

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

Code: [Select]

signal-event remoteaccess-update

Where do I start to troubleshoot?

Start with this command...

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

And view the logs in...

/opt/tomcat/logs

[william_syd]

This is what I did...

Code: [Select]

Login as root

mkdir sun

cd sun

Download latest JDK (jdk-6u7-linux-i586-rpm.bin)

chmod a+x jdk-6u7-linux-i586-rpm.bin

tar -xvzf apache-tomcat-6.0.14.tar.gz

mv apache-tomcat-6.0.14 /opt/tomcat

Go into server manager and create a user named tomcat

chown -R tomcat:tomcat /opt/tomcat/

chmod 770 /opt/tomcat/

signal-event user-modify tomcat

Tried as you suggested - I removed the previous installation and reinstalled exactly as you outined above.  Still nothin

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?

[EastEnder01]

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

[cactus]

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

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

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

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

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

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:

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...

Yes I did

Gives me this:

Using CATALINA_HOME:   /opt/tomcat

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...

[EastEnder01]

when i try going to www.mysite:8080 I get a "Page cannot be found error"

[william_syd]

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.
