systemd init script #39

Hi, how to create a systemd init script for application using endless package ?

Thank you

klingtnet commented 7 years ago

The process is the same as for any other systemd service script except that ExecReload should be defined. You can probably copy and paste the example from the manual:

[Service]
...
ExecReload=/bin/kill -HUP $MAINPID
...

@klingtnet Thank you

However, I'm using capistrano style deployment, and ExecReload together with WorkingDir does not work well, it's a hit and miss, sometimes it works, many times don't

That's strange, systemd should keep track of the processes new PID and the working dir should also be inherited from the forked process. Unfortunately, I don't have any experience with Ruby/capistrano, so good luck.
