When your machine turns on or reboots, you want certain things to happen automatically. If the 'machine' is a web server hosting websites defined by [[Apache]] and also a database server running [[MySQL]], then naturally you would want Apache and MySQL to start automatically. In SysV-style systems that still use <code>init</code> and the rc.d run levels, you can use either <code>chkconfig</code><ref>http://linuxcommand.org/man_pages/chkconfig8.html</ref> (RedHat and derivatives) or <code>sysv-rc-conf</code> or <code>update-rc.d</code><ref>http://manpages.ubuntu.com/manpages/precise/man8/update-rc.d.8.html</ref>for Debian variants to make that permanent. The old SysV style init has now largely been replaced by <code>systemd</code>, so this article is just to guide you through some of the equivalents across multiple ways of doing init.

To switch to single-user mode, what used to be called '''runlevel 1''', on a modern Linux running SystemD, you would now use the command:

<code>sudo systemctl isolate rescue.target</code>
