Gearman Job Server / Ubuntu

  • 772

I have Gearman installed, running and passing jobs around perfectly fine but only when I manually start up the job queue with this command:

/usr/sbin/gearmand -p 4730 -vvvv -u gearman

If I do this I have another EC2 instance running as a worker and a third passing in jobs. Perfect, but I don't want to have to keep a terminal open (obviously) or mess around with screen. I'd like this to run on startup.

So:

$ ps aux | grep gearman
gearman    745  0.2  0.2   8096  1388 ?        Ss   19:11   0:00 /usr/sbin/gearmand --pid-file=/var/run/gearman/gearmand.pid --user=gearman --daemon --log-file=/var/log/gearman-job-server/gearman.log --listen=127.0.0.1

Looks good to me. But when I tell my worker to connect:

$ php workers/resize.php 
Waiting for job...
PHP Warning:  GearmanWorker::work(): gearman_connection_flush:write:111 in /home/ubuntu/workers/resize.php on line 20

Fail!

Also I have noticed nothing is going into the log file (it was not created automatically, but was referenced in this init.d script on install). I tried creating it and even chowning to gearman:gearman but no joy there, so it's tough to debug.

    The problem is that the daemon is listening on 127.0.0.1/local loopback rather than a public IP.

    This is specified in /etc/default/gearman-job-server on Ubuntu.

    Change it to the public IP of the machine, restart the daemon with the init script and all should be well.

  2. Typically this error happens due to a parameter in GearmanClient::addServer(). It doesn't like "localhost" as a parameter. Try specifying 127.0.0.1 or specifying nothing.
