# Configuration

beaqnstalkd has no configuration file and only a handful of command-line options.

# Options

• -b <path>

  Use a binlog to keep jobs on persistent storage in directory <path>. Upon startup, beanstalkd will recover any binlog that is present in <path>, then, during normal operation, append new jobs and changes in state to the binlog.

• -c

  Perform online, incremental compaction of binlog files. Negates -n. This is the default behavior.

  Do not use this option, except to negate -n. Both -c and -n will likely be removed in a future beanstalkd release.

• -f <ms>

  Call fsync at most once every <ms> milliseconds. Larger values for <ms> reduce disk activity and improve speed at the cost of safety. A power failure could result in the loss of up to <ms> milliseconds of history.

  A <ms> value of 0 will cause beanstalkd to call fsync every time it writes to the binlog.

  This option has no effect without -b.

• -F

  Never call fsync. Equivalent to -f with an infinite <ms> value.

  This is the default behavior.

  This option has no effect without -b.

• -h

  Show a brief help message and exit.

• -l <addr>

  Listen on address <addr> (default is 0.0.0.0).

  Option -l has no effect if sd-daemon(5) socket activation is being used.

  See also Environment.

• -n

  Turn off binlog compaction, negating -c.

  Do not use this option. Both -c and -n will likely be removed in a future beanstalkd release.

• -p <port>

  Listen on TCP port <port>. Default is 11300.

  Option -p has no effect if sd-daemon socket activation is being used.

  See also Environment.

• -s <bytes>

  The size in bytes of each binlog file.

  This option has no effect without -b.

• -u <user>

  Become the user <user> and its primary group.

• -V

  Increase verbosity. May be used more than once to produce more verbose output. The output format is subject to change.

• -v

  Print the version string and exit.

• -z <bytes>

  The maximum size in bytes of a job.

# Environment

• LISTEN_PID, LISTEN_FDS

  These variables can be set by init. See sd_listen_fds for details.
