The spawn-fcgi command is included with the lighttpd + web server, but can be used with both Apache and lighttpd (and any other web server supporting + externally managed FCGI processes). + + You decide a starting port (default is 8000) and the number of FCGI process instances you'd + like to run. So if you pick 9100 and 3 instances, you'll start processes on 9100, 9101, and 9102. + + Examples: + spawner # starts instances on 8000, 8001, and 8002 + spawner -p 9100 -i 10 # starts 10 instances counting from 9100 to 9109 + EOF + + opts.on(" Options:") + + opts.on("-p", "--port=number", Integer, "Starting port number (default: #{OPTIONS[:port]})") { |OPTIONS[:port]| } + opts.on("-i", "--instances=number", Integer, "Number of instances (default: #{OPTIONS[:instances]})") { |OPTIONS[:instances]| } + opts.on("-e", "--environment=name", String, "test|development|production (default: #{OPTIONS[:environment]})") { |OPTIONS[:environment]| } + opts.on("-s", "--spawner=path", String, "default: #{OPTIONS[:spawner]}") { |OPTIONS[:spawner]| } + opts.on("-d", "--dispatcher=path", String, "default: #{OPTIONS[:dispatcher]}") { |dispatcher| OPTIONS[:dispatcher] = File.expand_path(dispatcher) } + + opts.separator "" + + opts.on("-h", "--help", "Show this help message.") { puts opts; exit } + + opts.parse! +end + +ENV["RAILS_ENV"] = OPTIONS[:environment] +OPTIONS[:instances].times { |i| spawn(OPTIONS[:port] + i) }
