MacPortで入れたMySQLの自動起動設定

MacPortsで入れたMySQLの自動起動設定。システム環境設定からやる方法もあるけどこっちの方が好き。
MacOS 10.6.7環境

$ sudo mkdir -p /opt/local/etc/LaunchDaemons/org.macports.mysql5
$ cd /opt/local/etc/LaunchDaemons/org.macports.mysql5
$ sudo curl -O http://robwilkerson.org/_resources/hotlink/blog/mysql5.wrapper
$ sudo curl -O http://robwilkerson.org/_resources/hotlink/blog/org.macports.mysql5.plist
$ sudo chown root:wheel /opt/local/etc/LaunchDaemons/org.macports.mysql5/*
$ sudo chmod 755 /opt/local/etc/LaunchDaemons/org.macports.mysql5/mysql5.wrapper
$ sudo chmod 644 /opt/local/etc/LaunchDaemons/org.macports.mysql5/org.macports.mysql5.plist
$ sudo ln -s /opt/local/etc/LaunchDaemons/org.macports.mysql5/org.macports.mysql5.plist /Library/LaunchDaemons/org.macports.mysql5.plist
