Configure Tomcat To Run on Linux Startup

Auto-start Apache Tomcat on Linux

If you are using the core version of Apache Tomcat and would like auto-start it on Linux here are the simple steps. I assume that you already have a running Apache Tomcat and know how to navigate to the terminal and have necessary system permission to proceed with this tutorial. Depending on the distribution that you are using you may need to find a specific location for the configuration or init.d folder.

1. Start by creating startup script into folder /etc/init.d/ or /etc/rc.d depending on what Linux distribution you are using.

$sudo vi tomcat

2. Enter the following scripts inside tomcat file

#!/bin/bash
# 
# tomcat
#
# chkconfig: 35
# description: Start up the Tomcat servlet engine.
# processname: tomcat

# /etc/init.d/tomcat


RETVAL=$?
CATALINA_HOME="/opt/apache-tomcat-8.5.30"

case "$1" in
 start)
        if [ -f $CATALINA_HOME/bin/startup.sh ];
          then
    echo $"Starting Tomcat"
            $CATALINA_HOME/bin/startup.sh
        fi
;;
 stop)
        if [ -f $CATALINA_HOME/bin/shutdown.sh ];
          then
    echo $"Stopping Tomcat"
            $CATALINA_HOME/bin/shutdown.sh
        fi
;;
 *)
 echo $"Usage: $0 {start|stop}"
exit 1
;;
esac

exit $RETVAL

NOTE
You will need to set the CATALINA_HOME and point it to the location where you deploy your Apache Tomcat.

Example:

CATALINA_HOME="/opt/apache-tomcat-8.5.30"

3. In this tutorial, we will create a symbolic link in Runlevel 3

$cd /etc/init.d/rc5.d/
$sudo ln -s ../init.d/tomcat S01tomcat
$sudo ln -s ../init.d/tomcat K01tomcat

In case you’re wondering, what S or K means: S is to start the application and K stands for to kill or shutdown the application. The number denotes the order. There are a lot of articles already available on the Internet about Linux Runlevel. You can check out Linux Runlevels Explained and Understanding init scripts

Distribution Notes

SLES 11 SP4
In SLES11, once you created the files tomcat1 and tomcat2 inside init.d folder you don’t need to create the symbolic link manually. Instead, execute the following command

$chkconfig --set tomcat1 on
$chkconfig --set tomcat2 on

To verify type the following code

$chkconfig

The output should look like this.

runlevel services via chkconfig
