Installing Tomcat on VPS will not enable tomcat service through which users can stop and restart tomcat using command service tomcat restart. To enable this service you will have to create a new file in /etc/init.d as tomcat and also you have to copy the following contents into it which are given below:-
#vi /etc/init.d/tomcat
#!/bin/bash
#
# Startup script for Tomcat
#
# chkconfig: 345 84 16
# description: Tomcat jakarta JSP server
#Necessary environment variables
export CATALINA_HOME=”/usr/local/tomcat”
if [ ! -f $CATALINA_HOME/bin/catalina.sh ]
then
echo “Tomcat not available…”
exit
fi
start() {
echo -n -e ‘\E[0;0m'"\033[1;32mStarting Tomcat: \033[0m \n"
su -l tomcat -c $CATALINA_HOME/bin/startup.sh
echo
touch /var/lock/subsys/tomcatd
sleep 3
}
stop() {
echo -n -e '\E[0;0m'"\033[1;31mShutting down Tomcat: \033[m \n"
su -l tomcat -c $CATALINA_HOME/bin/shutdown.sh
rm -f /var/lock/subsys/tomcatd
echo
}
status() {
ps ax --width=1000 | grep "[o]rg.apache.catalina.startup.Bootstrap start” | awk ‘{printf $1 ” “}’ | wc | awk ‘{print $2}’ > /tmp/tomcat_process_count.txt
read line < /tmp/tomcat_process_count.txt
if [ $line -gt 0 ]; then
echo -n “tomcatd ( pid ”
ps ax –width=1000 | grep “[o]rg.apache.catalina.startup.Bootstrap start” | awk ‘{printf $1 ” “}’
echo -n “) is running…”
echo
else
echo “Tomcat is stopped”
fi
}
case “$1? in
start)
start
;;
stop)
stop
;;
restart)
stop
sleep 3
start
;;
status)
status
;;
*)
echo “Usage: tomcatd {start|stop|restart|status}”
exit 1
esac
Once you run the above commands save and exit from the file and now assign permissions to files that you have created
#chown 755 /etc/init.d/tomcat
Enable it for all the Run-levels
#chkconfig –add tomcat
#chkconfig tomcat on
After the permissions are set you can Start, Stop and restart Tomcat on VPS by using the following commands given below:-
#service tomcat restart <<< To restart tomcat
#service tomcat stop <<< To stop Tomcat
#service tomcat start <<< To start Tomcat
#service tomcat Status <<< to check the status of Tomcat
