MySQL will not start

The most common reason for the MySQL database server not starting is that another MySQL database is already running on the same port. To find out if this is the case, do the following:

  1. Quit MAMP PRO.
  2. Open the Activity Monitor located in your /Applications/Utilities folder.
  3. Activate the entry “All Processes” in the “View” menu.
  4. Type “mysqld” into the search field on the top right.

    Activity Monitor - mysqld

  5. Quit every process you find after your search.
  6. Restart MAMP PRO.
  7. If MySQL still refuses to start check the log file for error messages.
