Note to self: Stop forgetting this!
Make a service start at boot:
chkconfig httpd --add chkconfig httpd on --level 235
Check if a service has been set this way:
chkconfig --list httpd
What is that –level ### stuff?
1 Single-User mode
2 Multi-user mode console logins only (without networking)
3 Multi-User mode, console logins only
4 Not used/User-definable
5 Multi-User mode, with display manager as well as console logins (X11)
Thanks Wikipedia for the table!
Most users run X from one of two runlevels: 3 or 5. Runlevel 3 places your system in multi-user mode with full networking capabilities. The machine will boot to a text-based login prompt with all necessary preconfigured services started. Most servers are run in runlevel 3, as X is not necessary to provide any services utilized by most users. Runlevel 5 is similar to 3, except that it automatically starts X and provides a graphical login screen. Many workstation users prefer this method, because it never forces them to see a command prompt.
