Example LINUX init Script
From time to time, people want me to create LINUX init scripts for them. I usually just take an existing one for another service and change it up to work for my new application, but most of them have become so long these days that I end up having to hack out a ton of code just to reduce them down to the very basic script I need. I decided to create this very simple template so I wouldn’t have to keep trimming down the more complex scripts that one tends to find in /etc/init.d these days.
This script is chkconfig compatible, so call it the name of your new service and put it in /etc/init.d
The chkconfig: 235 section indicates the the default runlevels. For instance, if we called this script /etc/init.d/new-service and ran chkconfig new-service on, it would be active in runlevels 2,3 and 5.
The 98 and 55 numbers indicate the order of startup and kill. This means that using this tag, the startup symbolic link would be named S98new-service and the symbolic link to kill the process would be named K55new-service.

Obviously change all instances of “new-service” to the name of your actual service… Enjoy!
