, 10:21, 17 December 2014→Starting up programs automatically upon system boot: add runlevel 4 for SME 9
If your package implements a server or daemon, you will probably want it to be started automatically when the system boots.
If your package implements a server or daemon, you will probably want it to be started automatically when the system boots.
The SME Server boots in runlevel 7, so you can get an idea of the startup processes by listing the contents of <tt class="FILENAME">/etc/rc.d/rc7.d</tt>.
The SME Server 8.1 boots in runlevel 7, SME Server 9.0 boots in runlevel 4, so you can get an idea of the startup processes by listing the contents of <tt class="FILENAME">/etc/rc.d/rc7.d</tt>. (or rc4.d for SME Server 9.0)
These are similar to the init scripts you may be familiar with from other Linux systems, with one important differnce. Instead of pointing to scripts within <tt class="FILENAME">/etc/rc.d/init.d</tt>, all of those init entries are links to <tt class="FILENAME">/etc/rc.d/init.d/e-smith-service</tt>. This is a wrapper which checks the configuration database to see if the service is supposed to be running and if so, starts the service from <tt class="FILENAME">/etc/rc.d/init.d/whatever</tt>.
