Hi there

I have installed mongrel using rubygems and I have filled the mongrel  
configuration file in my rails config directory, which is:

cwd: /var/www/my\_http\_dir/  
log\_file: log/mongrel.log  
port: “8100”  
environment: production  
address: 127.0.0.1  
pid\_file: tmp/pids/mongrel.pid  
servers: 2

The problem is that when I try to start mongrel using the command line  
order ‘mongrel\_rails mongrel::start -C config/mongrel\_cluster.yml’  
appears this error message

\*\* Ruby version is not up-to-date; loading cgi\_multipart\_eof\_fix  
\*\* Loading settings  
from  
/var/www/ktala/mob1970.org/cheatsheetsandrecipes/config/mongrel\_cluster.yml  
(they override command line).  
!!! Unknown configuration setting: servers  
mongrel::start reported an error. Use mongrel\_rails mongrel::start -h  
to get help.

Can anybody tell me what is happening? Why servers params is not ok?

Thanks in advance

Regards

Miquel

First… First I would recommend that you use thin and not mongrel…

Second… Whats your ruby version? ruby -v

Third… are you able to start one mongrel like so mongrel\_rails start  
-d ?
