Linux – shutting down tomcat process smoothly in Linux

linuxtomcat

This has been bugging me for a while.

In my JSF development cycle, I do a lot of tomcat reload and sometimes to the point of restarting tomcat. I notice that at times, shutting down tomcat using shutdown.sh doesn't work, because when starting it via startup.sh says the address is already in use for port 8080. And in the linux shell, I have to do something like this:

ps auwx | grep -i tomcat
kill -9 <tomcatPid>

Is there any way to be able to shutdown tomcat cleanly, like the the tomcat service in Windows ?

I'm currently using opensuse linux 11.2, and I don't add my tomcat onto my services yet.
Still starting and shutdown it manually from the shell.

You can avoid 2 commands by simply running:

pkill -f catalina

to gracefully kill process matching with text catalina.

And to check whether catalina process is still running you can then do:

pgrep -fl catalina

And finally to kill with brute force try:

pkill -9 -f catalina

Tomcat – Cron shell script to restart Tomcat

This is a rough outline of a script that would do what you want. Of course, you'll have to flesh it out and you can change the argument to sleep (shown here as five seconds).

#!/bin/bash
while ps | grep | grep > /dev/null
do
    sleep 5
done
kill
restart

You can combine the two greps into one using a regular expression if necessary. Note: when you are doing this sort of thing, you can sometimes get false positives when grep finds itself (although your two greps prevent this). In order to avoid that, you can do grep [s]omething which will find "...something..." but not "grep something" in the output of ps.

Tomcat – Start & shutdown as tomcat as non-root user

Tomcat on ubuntu stores configuration under /etc/tomcat*. Normal users may not have read access to all configuration files (e.g. /etc/tomcat6/tomcat-users.xml). If you'd like to run tomcat as a normal user for testing/development I'd recommend just download tomcat binary distribution and untar/unzip to some directory under your $HOME. Then run bin/startup.sh and you're done. This also saves you the hassle of running sudo for each tomcat configuration change.

BTW, if you don't have specific requirements for Tomcat5 I'd recommend using a more recent version (Tomcat6/Tomcat7).
