NAME

start_server - a superdaemon for hot-deploying server programs

SYNOPSIS

  start_server [options] -- server-prog server-arg1 server-arg2 ...

  # start Plack using Starlet listening at TCP port 8000
  start_server --port=8000 -- plackup -s Starlet --max-workers=100 index.psgi

DESCRIPTION

This script is a frontend of Server::Starter. For more information please refer to the documentation of the module.

OPTIONS

--port=(port|host:port)

TCP port to listen to (if omitted, will not bind to any ports)

If host is not specified, then the program will bind to the default address of IPv4 ("0.0.0.0"). Square brackets should be used to specify an IPv6 address (e.g. --port=[::1]:8080)

--path=path

path at where to listen using unix socket (optional)

--dir=path

working directory, start_server do chdir to before exec (optional)

--interval=seconds

minimum interval to respawn the server program (default: 1)

--signal-on-hup=SIGNAL

name of the signal to be sent to the server process when start_server receives a SIGHUP (default: SIGTERM). If you use this option, be sure to also use --signal-on-term below.

--signal-on-term=SIGNAL

name of the signal to be sent to the server process when start_server receives a SIGTERM (default: SIGTERM)

--pid-file=filename

if set, writes the process id of the start_server process to the file

--status-file=filename

if set, writes the status of the server process(es) to the file

--envdir=ENVDIR

directory that contains environment variables to the server processes. It is intended for use with envdir in daemontools. This can be overwritten by environment variable ENVDIR.

--enable-auto-restart

enables automatic restart by time. This can be overwritten by environment variable ENABLE_AUTO_RESTART.

--auto-restart-interval=seconds

automatic restart interval (default 360). It is used with --enable-auto-restart option. This can be overwritten by environment variable AUTO_RESTART_INTERVAL.

--kill-old-delay=seconds

time to suspend to send a signal to the old worker. The default value is 5 when --enable-auto-restart is set, 0 otherwise. This can be overwritten by environment variable KILL_OLD_DELAY.

--restart

this is a wrapper command that reads the pid of the start_server process from --pid-file, sends SIGHUP to the process and waits until the server(s) of the older generation(s) die by monitoring the contents of the --status-file

--backlog

specifies a listen backlog parameter, whose default is SOMAXCONN (usually 128 on Linux). While SOMAXCONN is enough for most loads, large backlog is required for heavy loads.

--help

prints this help

--version

prints the version number
