So I used script/server webrick and it works, but how do I use MySQL  
now? I already configured database.yml… when I try to run  
script/server without webrick I get this error:

!!! Path to log file not valid: log/mongrel.log

Thanks for the help

Make sure that you have a log directory in your rails application’s  
root.

Do you have your config\database.yml set up something like this:

development:  
adapter: mysql  
database: myapp\_development  
username: root  
password: my\_pswd  
host: localhost

# Warning: The database defined as ‘test’ will be erased and

# re-generated from your development database when you run ‘rake’.

# Do not set this db to the same as development or production.

test:  
adapter: mysql  
database: myapp\_test  
username: root  
password: my\_pswd  
host: localhost

production:  
adapter: mysql  
database: myapp\_production  
username: root  
password: my\_pswd  
host: localhost
