Hi,

In RoR to start the app we normally use ‘ruby script/server’, in  
enhancement to these a gem was introduced to do the same work and that  
is mongrel.

the syntax for mongrel is ’ mongrel\_rails start -e -p  
 ’

to create a cluster that is to run the app in multiple ports and work as  
a daemon the mongrel cluster is used.

the syntax for mongrel cluster is ’ mongrel\_rails cluster::start ’

to make this command work first we have to create a mongrel\_cluster.yml  
with all required details

mongrel\_rails cluster::configure -e -p -a  
127.0.0.1 -N -c /path/to/your/app

this command will create a mongrel\_cluster.yml file which will be  
utilised by the mongrel cluster

Hope this info is clear,

Rgds
