gearmand man page

gearmand — Gearman client/worker connector.

Synopsis

gearmand --daemon

Description

This is the main executable for Gearman::Server. It provides command-line configuration of port numbers, pidfiles, and daemonization.

Options

--daemonize / -d
Make the daemon run in the background (good for init.d scripts, bad for running under daemontools/supervise).
--port=4730 / -p 4730
Set the port number, defaults to 4730.
--listen hostname / -L hostname
Address the server should listen on.

Default is
--pidfile=/some/dir/gearmand.pid
Write a pidfile when starting up
--debug=1
Enable debugging (currently the only debug output is when a client or worker connects).
--accept=10
Number of new connections to accept each time we see a listening socket ready. This doesn't usually need to be tuned by anyone, however in dire circumstances you may need to do it quickly.
--wakeup=3
Number of workers to wake up per job inserted into the queue.

Zero (0) is a perfectly acceptable answer, and can be used if you don't care much about job latency. This would bank on the base idea of a worker checking in with the server every so often.

Negative One (-1) indicates that all sleeping workers should be woken up.

All other negative numbers will cause the server to throw exception and not start.
--wakeup-delay=
Time interval before waking up more workers (the value specified by --wakeup) when jobs are still in the queue.

Zero (0) means go as fast as possible, but not all at the same time. Similar to -1 on --wakeup, but is more cooperative in gearmand's multitasking model.

Negative One (-1) means that this event won't happen, so only the initial workers will be woken up to handle jobs in the queue.
--version
Display the version and exit.
