= daemon-spawn * http://github.com/alexvollmer/daemon-spawn == DESCRIPTION: Daemon launching and management made dead simple. With daemon-spawn you can start, stop and restart processes that run in the background. Processed are tracked by a simple PID file written to disk. In addition, you can choose to either execute ruby in your daemonized process or 'exec' another process altogether (handy for wrapping other services). == SYNOPSIS: === WRITING A DAEMON: To create a new spawner, write a class that extends <tt>DaemonSpawn::Base</tt> and provides +start+ and +stop+ methods. For example: class MyServer < DaemonSpawn::Base def start(args) # process command-line args # start your bad self end def stop # stop your bad self end end MyServer.spawn!(:log_file => '/var/log/echo_server.log', :pid_file => '/var/run/echo_server.pid', :sync_log => true, :working_dir => File.dirname(__FILE__)) If you need command-line parameters, any arguments passed after one of the commands (start, stop, status or restart) will be passed to the +start+ method. The +spawn!+ method takes a hash of symbolized keys. At a minimum you _must_ specify the <tt>:working_dir</tt> option. You can also override the default locations for the log and PID files. See the <tt>examples</tt> directory for working examples. === RUNNING A DAEMON: Let's say that you have the example script listed above in <tt>bin/my_server</tt>. Here are the commands for starting, querying the status, restarting and stopping the daemon: bin/my_server start bin/my_server status bin/my_server restart bin/my_server stop Note that if any additional arguments are passed to either <tt>start</tt> or <tt>restart</tt> those will be passed to the +start+ method of an instance of your daemon class. == REQUIREMENTS: None! == INSTALL: * sudo gem install daemon-spawn == LICENSE: (The MIT License) Copyright (c) 2009 Evri, Inc.
