User Manual -% Rainbows! Hackers <rainbows-public@yhbt.net> -% December 3, 2009 - -# NAME - -rainbows - rackup-like command to launch Rainbows! - -# SYNOPSIS - -rainbows [-c CONFIG_FILE] [-E RACK_ENV] [-D] [RACKUP_FILE] - -# DESCRIPTION - -A rackup(1)-like command to launch Rack applications using Rainbows!. -It is expected to be started in your application root (APP_ROOT), -but the "working_directory" directive may be used in the CONFIG_FILE. - -While Rainbows! takes a myriad of command-line options for -compatibility with ruby(1) and rackup(1), it is recommended to stick -to the few command-line options specified in the SYNOPSIS and use -the CONFIG_FILE as much as possible. - -# RACKUP FILE - -This defaults to \"config.ru\" in APP_ROOT. It should be the same -file used by rackup(1) and other Rack launchers, it uses the -*Rack::Builder* DSL. - -Embedded command-line options are mostly parsed for compatibility -with rackup(1) but strongly discouraged. - -# UNICORN OPTIONS --c, \--config-file CONFIG_FILE -: Path to the Unicorn-specific config file. The config file is - implemented as a Ruby DSL, so Ruby code may executed. - See the RDoc/ri for the *Unicorn::Configurator* class for the full - list of directives available from the DSL. - --D, \--daemonize -: Run daemonized in the background. The process is detached from - the controlling terminal and stdin is redirected to "/dev/null". - Unlike many common UNIX daemons, we do not chdir to \"/\" - upon daemonization to allow more control over the startup/upgrade - process. - Unless specified in the CONFIG_FILE, stderr and stdout will - also be redirected to "/dev/null". - --E, \--env RACK_ENV -: Run under the given RACK_ENV. See the RACK ENVIRONMENT section - for more details. - --l, \--listen ADDRESS -: Listens on a given ADDRESS. ADDRESS may be in the form of - HOST:PORT or PATH, HOST:PORT is taken to mean a TCP socket - and PATH is meant to be a path to a UNIX domain socket. - Defaults to "0.0.0.0:8080" (all addresses on TCP port 8080) - For production deployments, specifying the "listen" directive in - CONFIG_FILE is recommended as it allows fine-tuning of socket - options. --N, \--no-default-middleware -: Disables loading middleware implied by RACK_ENV. This bypasses the - configuration documented in the RACK ENVIRONMENT section, but still - allows RACK_ENV to be used for application/framework-specific purposes. - -# RACKUP COMPATIBILITY OPTIONS --o, \--host HOST -: Listen on a TCP socket belonging to HOST, default is - "0.0.0.0" (all addresses). - If specified multiple times on the command-line, only the - last-specified value takes effect. - This option only exists for compatibility with the rackup(1) command, - use of "-l"/"\--listen" switch is recommended instead. - --p, \--port PORT -: Listen on the specified TCP PORT, default is 8080. - If specified multiple times on the command-line, only the last-specified - value takes effect. - This option only exists for compatibility with the rackup(1) command, - use of "-l"/"\--listen" switch is recommended instead. - --s, \--server SERVER -: No-op, this exists only for compatibility with rackup(1). - -# RUBY OPTIONS --e, \--eval LINE -: Evaluate a LINE of Ruby code. This evaluation happens - immediately as the command-line is being parsed. - --d, \--debug -: Turn on debug mode, the $DEBUG variable is set to true. - --w, \--warn -: Turn on verbose warnings, the $VERBOSE variable is set to true. - --I, \--include PATH -: specify $LOAD_PATH. PATH will be prepended to $LOAD_PATH. - The \':\' character may be used to delimit multiple directories. - This directive may be used more than once. Modifications to - $LOAD_PATH take place immediately and in the order they were - specified on the command-line. - --r, \--require LIBRARY -: require a specified LIBRARY before executing the application. The - \"require\" statement will be executed immediately and in the order - they were specified on the command-line. - -# SIGNALS - -The following UNIX signals may be sent to the master process: - -* HUP - reload config file, app, and gracefully restart all workers -* INT/TERM - quick shutdown, kills all workers immediately -* QUIT - graceful shutdown, waits for workers to finish their - current request before finishing. -* USR1 - reopen all logs owned by the master and all workers - See Unicorn::Util.reopen_logs for what is considered a log. -* USR2 - reexecute the running binary. A separate QUIT - should be sent to the original process once the child is verified to - be up and running. -* WINCH - gracefully stops workers but keep the master running. - This will only work for daemonized processes. -* TTIN - increment the number of worker processes by one -* TTOU - decrement the number of worker processes by one - -See the [SIGNALS][4] document for full description of all signals -used by Rainbows!. - -# RACK ENVIRONMENT - -Accepted values of RACK_ENV and the middleware they automatically load -(outside of RACKUP_FILE) are exactly as those in rackup(1): - -* development - loads Rack::CommonLogger, Rack::ShowExceptions, and - Rack::Lint middleware -* deployment - loads Rack::CommonLogger middleware -* none - loads no middleware at all, relying - entirely on RACKUP_FILE - -All unrecognized values for RACK_ENV are assumed to be -"none". Production deployments are strongly encouraged to use -"deployment" or "none" for maximum performance. - -Note the Rack::ContentLength and Rack::Chunked middlewares are also -loaded by "deployment" and "development", but no other values of -RACK_ENV. If needed, they must be individually specified in the -RACKUP_FILE, some frameworks do not require them. - -# SEE ALSO - -* unicorn(1) -* *Rack::Builder* ri/RDoc -* *Unicorn::Configurator* ri/RDoc -* [Rainbows!
