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… /usr/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:30:in `gem_original_require': no such file to load -- /home/rails/projects/jokes/config/environment (LoadError) from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:30:in`require’ from /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel/rails.rb:157:in `rails' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/bin/mongrel_rails:116:in`cloaker\_’ from /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel/configurator.rb:138:in `call' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel/configurator.rb:138:in`listener’ from /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/bin/mongrel\_rails:98:in `cloaker_' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel/configurator.rb:51:in`call’ from /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel/configurator.rb:51:in `initialize' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/bin/mongrel_rails:83:in`new’ from /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/bin/mongrel\_rails:83:in `run' from /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel/command.rb:211:in`run’ from /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/bin/mongrel\_rails:248 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.
