rpos.js as systemd service

[cdaher78]

Hello brothers.

If I run node rpos.js directly at /home/pi/rpos the service inits correctly without any issues.

But I need to make it run automatically and tried to make rpos.js to init as a service on raspberry reboot.

When I start the service it soon fails.

service parameters on /lib/systemd/system/onvifcam.service

[Service] Type=simple User=pi ExecStart=/usr/bin/node /home/pi/rpos/rpos.js

I have added /home/pi/rpos to PATH.

node version is v8.17.0 npm version is 6.13.4 OS is Raspberry Pi OS 10 (Buster)

What am I missing here? I'm not aware of Node.js particularities.

Thanks.

The error log says Error: ENOENT: no such file or directory, open './rposConfig.json'

It cannot find the config file

You probably need to set the folder it runs from in the Systemd config file. It will be called something like Run Directory, or PWD or CWD or Start Folder

Hey Roger,

Thanks for your comment.

After some research and struggling I've made it work. At the service file was needed to point for a "WorkingDirectory".

There goes working service config:

[Unit] Description=ONVIF/RTSP Server Requires=network.target After=network.target

[Service] Type=simple Restart=always StandardOutput=syslog StandardError=syslog SyslogIdentifier=onvifcam User=pi WorkingDirectory=/home/pi/rpos ExecStart=/usr/bin/node rpos.js

[Install] WantedBy=multi-user.target

It would be great if this project were compatible with Bullseye and newer versions of Node.js and multi streaming capability (at least 2 different and editable streams with his own resolution, framerate, bitrate).

Congrats to you and the contributors for this awesome development job.

Hi I've added your startup service to the project. Many thanks Roger
