Cannot start the domoticz daemon in systemd but can be started in terminal

[cmisip]

The systemd script in /etc/systemd/system is:

Code: Select all

[Unit]
Description=Domoticz Home Automation Service
After=network-online.target

[Service]
Type=simple
User=pi
Group=pi
WorkingDirectory=/home/pi/domoticz
ExecStart=/home/pi/domoticz/domoticz -daemon -www 8080 -sslwww 443 -pidfile /var/run/domoticz/domoticz.pid
Restart=on-failure

[Install]
WantedBy=multi-user.target

The result of starting the systemd script:

Code: Select all

If I run the execstart code in the command line, the domoticz daemon is created. Why can't systemd do the same?

Code: Select all

home/pi/domoticz/domoticz -daemon -www 8080 -sslwww 443 -pidfile /var/run/domoticz/domoticz.pid

Result of running in commandline as user pi:

Code: Select all

pi@rpidhcpserver:~/domoticz $ /home/pi/domoticz/domoticz -daemon -www 8080 -sslwww 443 -pidfile /var/run/domoticz/domoticz.pid

domoticz: Domoticz is starting up....

I did use systemd tmpfiles.d to create /run/domoticz. /etc/tmpfiles.d/domoticz.conf contains

Code: Select all

#Type Path        Mode UID        GID        Age Argument
d     /run/domoticz 0755 pi     pi     -   -

Thanks,

I think I figure it out. Type has to be oneshot and RemainAfterExit=yes so ExecStop is not called immediately.

Code: Select all

[Unit]
Description=Domoticz Home Automation Service
After=network-online.target

[Service]
Type=oneshot
User=pi
Group=pi
WorkingDirectory=/home/pi/domoticz
ExecStart=/home/pi/domoticz/domoticz -daemon -www 8080 -sslwww 4443 -pidfile /var/run/domoticz/domoticz.pid
RemainAfterExit=yes
Restart=on-failure
RestartSec=5s

[Install]
WantedBy=multi-user.target
