Hi there,

I’m new to playing with EventMachine and I wondered if anyone has a nice  
way of backgrounding it and start / stopping it from the command line  
like an init script.

e.g. ./mydaemon start|stop

I’ve not seen an example of this and search through the Juggernaut gem  
source I couldn’t get the come I’d stolen from it to work with a basic  
echo server.

e.g. mydaemon start|stop

Any ideas?

Here’s what I did :

# =============================

# script/em\_manager

# I did a chmod +x on this file

#!/usr/bin/env ruby  
require ‘rubygems’  
require ‘daemons’  
options = {  
:app\_name =\> “em\_manager”,  
#:ARGV =\> [‘start’, ‘-f’, ‘–’, ‘param\_for\_myscript’]  
#:dir\_mode =\> :normal,  
#:dir =\> path,  
:multiple =\> false,  
#:ontop =\> true,  
:mode =\> :load,  
:log\_output =\> true,  
#:keep\_pid\_files =\> true,  
#:backtrace =\> true,

# :monitor =\> true

}

#=====================

# app/daemons/em\_client.rb

EventMachine::run {  
(…)  
}

Daemons.run(’./app/daemons/em\_client.rb’, options)
