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)

--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

--version
