Hello.

I use capistrano with mongrel and apache.

When I cap deploy:start, It launches nothing. So I :  
sd-17133:/var/rails/canardps3/current# mongrel\_cluster\_ctl start  
Starting all mongrel\_clusters…  
/usr/local/bin/mongrel\_cluster\_ctl:7:in `chdir': No such file or directory - /etc/mongrel_cluster (Errno::ENOENT) from /usr/local/bin/mongrel_cluster_ctl:7:in`run’  
from /usr/local/bin/mongrel\_cluster\_ctl:55  
guess it may be the problem. Any idea on what can I do to fix this ?

Have you tried passing a configuration file in?

I have my config file for prod, qa, etc. under  
./config/{environment}\_mongrel.conf

The cluster can be started with -c ./path/to/config/file (which has  
startup directory, ports, etc)…or you can create a directory in  
/etc/mongrel\_cluster that has symlinks to all your config files for  
each environment.

Sylvain, can you post your mongrel\_cluster\_ctl to the list? It looks  
like  
your start script is trying to find a file but it’s not there.

clearly you are missing a configuration file on the server. /etc/  
mongrel\_cluster… you need to create a configuration file to start  
your mongrel cluster. It first looks into your rails config directory  
and then in /etc/mongrel\_clusters.

Ok, I get the config file, but in fact this don’t make the cap  
deploy:start  
working.

Some information :

my script/spin :

#!/bin/sh

/var/rails/canardps3/current/script/process/spawner \

mongrel \

–environment=production \

–instances=1 \

–address=127.0.0.1 \

–port=8000

my spawner :

#!/usr/bin/env ruby

require File.dirname(_ **FILE** _) + ‘/…/…/config/boot’

require ‘commands/process/spawner’

I got no error except  
C:\railsapp\canardps3\>cap deploy:start

- executing `deploy:start’
- executing “cd /var/rails/canardps3/current && sudo -p 'sudo  
password: ’

but a ps aux | grep mongrel isn’t returning a thing.

Were can I find some clue ?
