[systemd-devel] Best approach to run python service in virtualenv with systemd

[Stanislav Kopp]

Hi all,

I'm trying to run kallithea using virtualenv, it kinda works (I can
stop/start service) with this unit file

########################################
[Unit]
Description=Start Kallithea service
After=network.target

[Service]
Type=forking
User=kallithea
WorkingDirectory=/srv/kallithea
ExecStart=/srv/kallithea/venv/bin/python2
/srv/kallithea/venv/bin/paster serve --daemon
--pid-file=/srv/kallithea/kallithea.pid
--log-file=/srv/kallithea/kallithea.log my.ini
PIDFile=/srv/kallithea/kallithea.pid

[Install]
WantedBy=multi-user.target
#########################################

but I always see "Failed to read PID from file
/srv/kallithea/kallithea.pid: Invalid argument" in "systemctl status",
I know that "PIDFile" option isn't a best practice and should be
avoided, but withou it service doesn't running.
Is there any better methods to run it or at least remove this pid error message?


Thanks,
Stan
