==Start a boot a custom service==
===Start at the boot time a custom service===
If you want to start a custom service on the SME Server, you will have to follow some steps.

The init script below is just a wrapper, a launcher that will start the real script which will do the job for you (see SCRIPT=<COMMAND> to give the path to your job script). Of course the init script is here only if you want to add a service by hand and thus not installed by a rpm.<br />

In that case of you have installed a service which comes from a rpm but without init script in the runlevel 7 you have to follow from this [[Add_a_custom_service#allow_a_service_to_start_for_a_particular_time |section]]

You have to say to SME Server to add that script to each run level you have specified at the top of your init script( Default-Start: 2 3 4 5 and Default-Stop: 0 1 6 ). For Linux using rpm as centos or redhat, you can use

chkconfig YOUR_SERVICE_NAME --add
chkconfig YOUR_SERVICE_NAME --add
You can set the levels where the initscript has to start
chkconfig YOUR_SERVICE_NAME --level 2345 on
If you want to see which runlevel your script will run in
chkconfig YOUR_SERVICE_NAME --list
chkconfig YOUR_SERVICE_NAME --list
However it is not enough for SME server since we have to add service to rc7.d and to say to our distro to start that service at boot, therefore let's go to the section below

=== General Service Handling ===
=== General Service Handling ===
SME Server uses [http://smarden.org/runit/ runit], a UNIX init scheme with service supervision. See the man page of [http://smarden.org/runit/sv.8.html the 'sv' command]
All other linux common way to start or stop services are also valuable
