You can do this with the builtin chkconfig utility:

Code: Select all

sudo /sbin/chkconfig --list

This command show you all the services and their status on each runlevel.

If you don't see your service in it (mysqld for example?), you can add it.

Code: Select all

sudo /sbin/chkconfig --add mysqld

You also need to set it to ON, in the desired runlevel.
For servers this is mostly runlevel 3.

Code: Select all

sudo /sbin/chkconfig --level 3 mysqld on

Now it should start when the system is rebooted.

For the record the runlevels:
0 - Halt
1 - Single-user text mode
2 - Not used (user-definable)
3 - Full multi-user text mode
4 - Not used (user-definable)
5 - Full multi-user graphical mode (with an X-based login screen)
6 - Reboot
