systemd with logs to journald

systemd with logs to journald

[Bill Lipa]

Hello,

Is there a recommended way to run unicorn under systemd and get its
stdout/err to go to journald rather than into a file on disk?  I
prefer to minimize the number of places I have to look for errors.

Thank you!

Remove the stdout_path and stderr_path directives from the
config file.

unicorn won't change stdout/stderr by default, so journald
should pick up anything that goes there.

Admittedly, I haven't gotten around to trying journald, just
systemd + syslog.  That combo handles stdout/stderr fine.

No problem :>

Please don't drop the Cc: to unicorn-public@bogomips.org,
other readers are following along.

You should never need -D (--daemonize) with systemd or any
process manager.  -D is intended for standalone init scripts
when the launching process could go away before the daemon.

Yes, that service file should be the recommended way for
systemd.

Thanks for the pointers!  I came across the official example too late,
but I'll convert over now.
