Start applications after server restart

Question

How can I configure my CentOS 5.5 to autostart some applications after rebooting?
I want to start nginx, mysqld and call some commands like rvm use ree.

Answer 1

CentOS uses chkconfig to manage its startup scripts.
Type chkconfig --list to view the services that are configured to work with checkconfig, and their settings.
MySQL should already be in that list.

If it isn't already configured to be on at runlevel 3 (the default runlevel for centos servers), run chkconfig mysqld on

You could write your own startup script to work with chkconfig for Nginx. Then you'll be able to manage it the same way as MySQL.

To make the system run custom commands at startup, you can add them to the /etc/rc.local file.
