I have a CentOS 6 32bit VPS and I'd like to determine, How do I know which apps automatically run on startup?

EDIT: I have tried chkconfig --list but I don't understand what these lines meant:

[root@server2 ~]# chkconfig --list

The columns 0-6 are your runlevels. Basically the columns indicate which services are started/stopped at what system stage or run level.

Most systems/servers operate at runlevel 3, aka: 'init:3' in inittab terms.

Use the command runlevel to find what is the run level, which is the number before on or off. So if your run level is 2, you can grep 2:on from the above output and find all the services that are on. Usually run level is set in /etc/inittab, but can be changed.
