If you cannot start mysql service in snow leopard, as well as in the panel prefs seems 'warning the consumerOrnearbyOrmysql databaseOrinformation directory isn't possessed through the mysql user', you need to:

  • sudo chown -RL root:mysql /usr/local/mysql
  • sudo chown -RL mysql:mysql /usr/local/mysql/data
  • sudo /usr/local/mysql/support-files/mysql.server start

It labored for me personally
