• /etc/sysconfig/gearmand
  # This is a configuration file for /etc/init.d/gearman-job-server; it allows
# you to perform common modifications to the behavior of the gearman-job-server
# daemon startup without editing the init script (and thus getting prompted by
# dpkg on upgrades).  We all love dpkg prompts.

# Examples ( from http://gearman.org/index.php?id=manual:job_server )
#
# Use drizzle as persistent queue store
# PARAMS="-q libdrizzle --libdrizzle-db=some_db --libdrizzle-table=gearman_queue"
#
# Use mysql as persistent queue store
# PARAMS="-q libdrizzle --libdrizzle-host=10.0.0.1 --libdrizzle-user=gearman \
#                       --libdrizzle-password=secret --libdrizzle-db=some_db \
#                       --libdrizzle-table=gearman_queue --libdrizzle-mysql"
#
# Missing examples for memcache persitent queue store...

# Parameters to pass to gearmand.

• запускаем gearmand:
  chkconfig gearmand on
  /etc/init.d/gearmand start

• проверить, что в mysql cоздалась таблица queue
