Q: 

bindings between rails and mysql hosed after restoring to a new iMac

Had to restore from time machine/capsule to a new iMac after my MBP died. Everything but rails (2.3.5) connection to mysql is working.

My old socket connection in my database.yml was /opt/local/var/run/mysql5/mysqld.sock

To add to the fun, I seem to have multiple installs of mysql.

  1. How do I reconnect mysql to rails?
  2. How do I locate the "real" mysql, or where should it be installed?
  3. Is it safe to delete the rest?
  4. Is there a good url that will teach me how to troubleshoot this in the future?
