Adding services to Linux startup on boot

Many times, when installing a program or service on a Linux distribution, the installers do not take care of the process of creating the proper links/files to autostart the service upon reboot.

For my own reference, here it is:

This procedure is different for Ubuntu vs. CentOS.

Ubuntu

• update-rc.d serviceNameIn/etc/init.d defaults
• Here is a great reference

CentOS

• chkconfig serviceNameIn/etc/init.d on
• You may have to edit the init.d script by finding the line that reads:
• # chkconfig: - 64 36 ( for example ) and make sure the - is replaced by the runlevels you want it running in, i.e. 2345
  
• Here is a man page
