To run the RTPEngine under systemd control, follow these steps:
Clone the repository to your local machine:
# git clone https://github.com/voice4net/rtpengine-systemd.git
# cd rtpengine-systemd
Edit the configuration file "rtpengine-conf " to reflect your configuration. Then install the files in your system:
# cp rtpengine-conf /etc/default/rtpengine-conf
# cp rtpengine.service /usr/lib/systemd/system/rtpengine.service
# cp rtpengine-start /usr/bin/rtpengine/rtpengine-start
# cp rtpengine-stop-post /usr/bin/rtpengine/rtpengine-stop-post
# chmod +x /usr/bin/rtpengine/rtpengine-start
# chmod +x /usr/bin/rtpengine/rtpengine-stop-post
In the systemd unit file, the option "ExecStopPost" is used to clean the system after the RTPEngine daemon is stopped. This involves: deleting the forwarding table, the iptables related rules, and unload the kernel module (xt_RTPENGINE).
Now you can enable/start/stop/status of the rtpengine service as following:
# systemctl enable rtpengine.service
# systemctl start rtpengine.service
# systemctl status rtpengine.service
# systemctl stop rtpengine.service
If you do enable, then the rtpengine will be automatically started by the systemd after boot.
Note: This work is a translation of the SipWise ngcp-rtpengine-daemon.init script to what Systemd needs.
