Mongrel working but not mongrel cluster!

Rails Deployment

Hi guys,

I have installed mongrel and mongrel cluster in a new linux box … at
the end of the day I was able to lunch mongrel (mongrel_rails start -e
production) and all is working fine with.
However, when I tried to set a mongrel cluster the command mongrel_rails
cluster::start get the following output :

starting port 8000
starting port 8001
starting port 8002

But when I lunched the browser to the application url and port 8000 for
example, the mongrels seems not working.

I looked at the log file and get for the first mongrel instance :

** Daemonized, any open files are closed. Look at tmp/mongrel.8000.pid
and log/mongrel.8000.log for info.
** Starting Mongrel listening at 0.0.0.0:8000
** Changing group to mongrel.
** Changing user to mongrel.
** Starting Rails with production environment…
** Mounting Rails at /home/rails/projects/myapps…

from /usr/bin/mongrel_rails:16:in `load’
from /usr/bin/mongrel_rails:16

It’s the same thing for the two other instances.

My mongrel cluster configuration is as follows :

user: mongrel
group: mongrel
cwd: /home/rails/projects/myapps
log_file: log/mongrel.log
port: “8000”
environment: production
address: 127.0.0.1
pid_file: tmp/mongrel.pid
servers: 3

Can anyone give help me to get out of this ?

Thanks a lot in adavance

YAY … I finally find the problem !!!

Here’s how I proceeded … there are some mongrel_cluster behavior I
don’t yet understand but at least it’s now working fine on my server.

I checked if mongrel_rails start will work without specifying a
mongrel_cluster.yml … and yes it works !!
However, in the default setting only two instances are lunched from
ports 3000 and 3001.
As I checked the code source of mongrel_rails, it seems that it’s
merging the parameters passed to it with default ones (right ?).
So I tried to overwrite only the important parameters … like the port
numbers the number of servers and the environment variable. So I
modified my mongrel_cluster.yml from :

user: mongrel
group: mongrel
cwd: /home/rails/projects/myapps
log_file: log/mongrel.log
port: “8000”
environment: production
address: 127.0.0.1
pid_file: tmp/pids/mongrel.pid
servers: 3
debug: true

to

port: “8000”
environment: production
servers: 3

And now the command :

mongrel_rails cluster::start -C
/home/rails/projects/myapps/config/mongrel_cluster.yml

et voilà tout marche bien !!!

I hope that this will help some of you.
