MySQL will not start

The most common reason for MySQL not starting is that another MySQL process is already running on the same port. To check for this and resolve it:

  1. Quit MAMP PRO.

  2. Open Activity Monitor (/Applications/Utilities/Activity Monitor).

  3. In the View menu, select All Processes.

  4. Type mysqld into the search field in the top right.

    Activity Monitor - mysqld

  5. Quit every mysqld process listed in the results.

  6. Start MAMP PRO again.

  7. If MySQL still does not start, check the log file for error messages.
