With no modification, attempting to start the service through systemd produces a fatal error.
journalctl -xeu trafficserver.service:
> traffic_cop[5972]: unable to locate local state directory '/var/run/trafficserver'
Attempting to resolve this issue through custom systemd unit with RuntimeDirectory option results in another fatal error due to insufficient permissions (a symptom of configuration, not the root cause).
/etc/systemd/system/trafficserver.service.d/runtimedir_override.conf
> [Service]
> RuntimeDirectory=trafficserver
journalctl -xeu trafficserver.service:
> traffic_manager[6493]: Fatal: [LocalManager::initMgmtProcessServer] failed to bind socket at /var/run/trafficserver/processerver.sock
The resolution is to be able to create this directory with the expected write permission for trafficserver, or more preferrably override it in the environment defaults for the unit in /etc/defaults/trafficserver.
It's perhaps better to use tmpfiles.d for this, but I like being able to clean up the process directory on exit (especially in /run), so I've come up with a systemd solution.
This can either go in the /lib/systemd/system/trafficserver.service file (beware of upgrades), or in a custom unit under /etc/systemd/system/trafficserver.service.d/ .
Additionally, this solution requires that you have the 'install' program on your system.
The actual paths will most likely depend on your system.
/etc/systemd/system/trafficserver.service.d/runtimedir_override.conf
> [Service]
> ExecStartPre=/usr/bin/install -m0755 -o trafficserver -g trafficserver -d /run/trafficserver
> ExecStopPost=/bin/rm -r /run/trafficserver
I'm providing this as my resolution to this issue. I haven't seen this fix anywhere else short of creating a boot-time tmpfile.d directory or manually creating a permanent directory. Hopefully this helps!
