ためしに、マニュアルで mongrel をリスタートしてみる

> mongrel_rails cluster::restart --clean
!!! Configuration file does not exist. Run mongrel_rails cluster::configure.
cluster::restart reported an error. Use mongrel_rails cluster::restart -h to get help.

Rails アプリケーションフォルダに入って、mongrel cluster configure してみる。

mongrel_rails cluster::configure -e production -p 3000 -N 2
mongrel_rails cluster::restart --clean

すると、スタートしたみたい。
