running Tomcat as a service/daemon on Linux

[Chris Ruegger <cr...@speakeasy.net>]

Is it possible to set up Tomcat on a Linux
machine such that I can start it/stop with the 
service command, i.e.

service tomcat start
service tomcat stop

If so, how would one do this? Do most people set up
Tomcat as a daemon on Unix machines? If so,
tips on how this is done appreciated!!

Copy the file TOMCAT/bin/tomcat.sh to the /etc/init.d directory.
the make the proper links to the run level directories. If you have
redhat, use the chkconfiig command after you copy the file.
i.e.

# to see what's running
chkconfig --list

#to turn on Tomcat
chkconfig -level 3 tomcat on

Tomcat does not use the daemon / service command to track
PID's it will issue a socket command when stopping.

all service does it to run a script found in /etc/init.d
(or /etc/rc.d/init.d on older systems).  So write a script
that starts and stops tomcat.

The Debian tomcat4 package comes with the following script
so it might need a bit of modification for your environment:-

f#! /bin/sh -e
#
# /etc/init.d/tomcat4 -- startup script for the Tomcat 4.0 servlet engine
#
# Written by Miquel van Smoorenburg <mi...@cistron.nl>.
# Modified for Debian GNU/Linux	by Ian Murdock <im...@gnu.ai.mit.edu>.
# Modified for Tomcat by Stefan Gybas <sg...@debian.org>.

PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
NAME=tomcat4
DESC="Tomcat 4.0 servlet engine"
DAEMON=/usr/bin/$NAME
CATALINA_HOME=/usr/share/$NAME

# The following variables can be overwritten in /etc/default/tomcat4

# Run Tomcat 4.0 as this user ID (default: tomcat4)
# Set this to an empty string to prevent Tomcat from starting automatically
TOMCAT4_USER=tomcat4

# The first existing directory is used for JAVA_HOME (if JAVA_HOME is not
# defined in /etc/default/tomcat4)
JDK_DIRS="/usr/lib/j2se/1.3 /usr/lib/j2sdk1.3"

# Arguments to pass to the Java virtual machine (JVM)
CATALINA_OPTS=""

# Use the Java security manager? (yes/no)
TOMCAT4_SECURITY="yes"

# End of variables that can be overwritten in /etc/default/tomcat4

# overwrite settings from default file
if [ -f /etc/default/tomcat4 ]; then
	. /etc/default/tomcat4
fi

test -f $DAEMON || exit 0

....and there you have your service.
Try service tomcat4 start and see what happens.
If you use sysv-init you can edit what runlevel you want tomcat to start.

I don't know what your OS is, but I installed via RPM and I have a 
script in /etc/rc.d/init.d named tomcat4.  No, it's not as handy as 
service tomcat4 start, but it works :-)  I typically wind up doing 
something like !?4 rest? anyway :-P (which grabs the last restart out of 
my history and executes it).  That's even shorter than service tomcat4 
restart :-D
