Examples of /etc/init.d/freeswitch

Unix-style /etc/init.d/freeswitch

The various unix-based systems often start FreeSWITCH from a script that lives in /etc/init.d/freeswitch.

Linux

Debian/Ubuntu

You should only need to use this if you are not installing from a pre-built package.

The existing start-up scripts can be found in the `src/freeswitch/debian/` directory, however these are tied in closely with the layout of the package builder and may not be suitable for your needs.

Below is a fully functional init.d script which you can use with any standard FreeSWITCH build (assuming you haven't changed --prefix).

Adding users / fixing permissions

Add the user and group to your system, and change the required permissions for the directory; replace with your installation location as required:

adduser --disabled-password  --quiet --system --home /usr/local/freeswitch --gecos "FreeSWITCH Voice Platform" --ingroup daemon freeswitch
chown -R freeswitch:daemon /usr/local/freeswitch/ 
chmod -R o-rwx /usr/local/freeswitch/

Installing the script

Create the file `/etc/init.d/freeswitch` with the following code:

/etc/init.d/freeswitch

#!/bin/bash

Make the script executable and make it auto start on system boot:

chmod +x /etc/init.d/freeswitch
update-rc.d freeswitch defaults

Run priority

You can modify the run priority in two places.

The first is using DAEMON_ARGS, using the arguments explained FreeSwitch_FAQ#Q:_How_do_I_setup_high_priority_to_my_freeswitch_daemon.3F, for example:

 DAEMON_ARGS="-nc -np" – normal (system) default priority
 DAEMON_ARGS="-nc -lp" – low priority
 DAEMON_ARGS="-nc -rp" – high real time priority

The second is to modify the --nicelevel of start-stop-daemon, for example:

	...
	DAEMON_ARGS="-nc -np" - normal (system) default priority
	...
	start-stop-daemon --start --quiet --nicelevel -19 --pidfile $PIDFILE --exec $DAEMON --test > /dev/null -- \
                || return 1
        do_setlimits
        start-stop-daemon --start --quiet --nicelevel -19 --pidfile $PIDFILE --exec $DAEMON -- \
                $DAEMON_ARGS \
                || return 2
	...

Fedora

Note: Also tested on CentOS 5.5 with perfect results, just as always set chmod +x /etc/init.d/freeswitch

This script runs FreeSWITCH as root (NOT RECOMMENDED)
Use the -u USER option to switch to a different user on startup. (see SECURITY NOTE in the script)

Be sure to run:

chkconfig freeswitch on

So that the script is added to all the rc#.d directories.
