Configuring a Default Runlevel or Target Unit

Whereas a persistent service is one that is started at server boot time, a persistent (default) runlevel or target unit is a group of services that are started at boot time. Both classic SysVinit and Upstart define these groups of services as runlevels, while systemd calls them target units.

Configuring the SysVinit default runlevel

You set the persistent runlevel for a Linux server using SysVinit in the /etc/inittab file. A portion of this file is shown here:

# cat /etc/inittab # # inittab This file describes how the INIT process should # set up the system in a certain run-level. ... id:5:initdefault: ...

The initdefault line in the example shows that the current default runlevel is runlevel 5. To change this, simply edit the /etc/inittab file using your favorite editor and change the 5 to one of the following runlevels: 2, 3, or 4. Do not use the runlevels 0 or 6 in this file! This would cause your server to either halt or reboot when it is started up.
