Init scripts on lucid have a pid file in /run which doesn't exist

[Rowan Wookey]

In nginx 1.2.4 from https://launchpad.net/~nginx/+archive/stable/ the lucid build is attempting to use the pid file in /run

start() {
  test_nginx_config
  # Check if the ULIMIT is set in /etc/default/nginx
  if [ -n "$ULIMIT" ]; then
   # Set the ulimits
   ulimit $ULIMIT
  fi
  start-stop-daemon --start --quiet --pidfile /run/$NAME.pid \
   --retry 5 --exec $DAEMON -- $DAEMON_OPTS || true
}

/run doesn't exist on lucid it should be reverted back to /var/run currently this build can't be restarted without killing nginx and the status check fails.

/run has been added to nginx-common.dirs so whether or not /run is part of the normal file system layout, it will be sure to exist. I can understand that this might break some policies for lucid, but lucid is the only release that currently lacks /run. I don't plan to maintain yet another "special case". Especially not one that I can solve with this simple solution.

This resolution has been uploaded and published in the ppa.

It's still broken since the pid file never gets put in /run the pid file is set to
pid /var/run/nginx.pid

You could either update nginx.conf to use /run/nginx.pid or symlink /run to /var/run/ in lucid.

[Michael Lustfield (michaellustfield)]

Are you using the latest PPA? Did you maybe make some modifications to
the init script before upgrading which prevented the new script from
being installed?

I did a fresh install on lucid.

/etc/nginx/nginx.conf sets the pid file to /var/run/nginx.pid hence the init script can't get the pid from /run on lucid.

[Michael Lustfield (michaellustfield)]

This is what I get for being too tired and working on things. I'll get this corrected as soon as I get home.

[Michael Lustfield (michaellustfield)]

This should be resolved now... Could you please check?

[Rowan Wookey (rwky)]

Yep that works, I tested both a clean install and an upgrade. Thank you :)

[Rowan Wookey (rwky)]

Scratch that now logrotate is broken, the logrotate file needs to be checking /var/run/nginx.pid

/etc/cron.daily/logrotate:
cat: /run/nginx.pid: No such file or directory
kill: 2: Usage: kill [-s sigspec | -signum | -sigspec] [pid | job]... or
kill -l [exitstatus]
error: error running shared postrotate script for '/var/log/nginx/*.log '
run-parts: /etc/cron.daily/logrotate exited with return code 1

[Thomas Ward (teward)]

I've uploaded a fix to the PPA that should fix the logrotate issue. Can you please check?

[Rowan Wookey (rwky)]

Yep that fixed, everything looks ok now.

[Thomas Ward (teward)]

Okay, marking as Fix Released, then.

[Michael Heuberger (michael.heuberger)]

Thomas, I'm still having this issue. What fix did you upload?

[Thomas Ward (teward)]

Michael, we only uploaded a fix to the PPA for nginx. Make sure you're using that. And of course, this could have been undone by a later update to the PPA. However, its usually customary to file a separate bug after one bug's been released/closed, can you do me a favor and tell me the package version(s) you're running, and whether or not they're from the PPA or not?

[Thomas Ward (teward)]

I've confirmed a regression exists that caused this bug to resurface. Please see this bug: https://bugs.launchpad.net/nginx/+bug/1131394

[Michael Heuberger (michael.heuberger)]

i'm running nginx version 1.2.7

[Thomas Ward (teward)]

The regression has been fixed in Bug 1131394.
