BEANSTALKD(1)BEANSTALKD(1)NAMEbeanstalkd - simple, fast work queue
SYNOPSISbeanstalkd [options]
DESCRIPTION
Beanstalkd is a simple work-queue service. Its interface is generic,
though it was originally designed for reducing the latency of page
views in high-volume web applications by running time-consuming tasks
asynchronously.
When started, beanstalkd opens a socket (or uses a file descriptor pro‐
vided by the init(1) system, see ENVIRONMENT) and listens for incoming
connections. For each connection, it reads a sequence of commands to
create, reserve, delete, and otherwise manipulate "jobs", units of work
to be done. See file doc/protocol.txt in the beanstalkd distribution
for a thorough description of the meaning and format of the beanstalkd
protocol.
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(2) 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(2). 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(5) 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(1). See sd_listen_fds(3) for
details.
