У меня проблема с MAMP, я устанавливаю порты следующим образом: Apache: 8888 MySQL: 8889, но MySQL не работает. Итак, я прочитал файл mysql_error_log.err, у меня есть это:

161018 14:21:13 mysqld_safe mysqld from pid file /Applications/MAMP/tmp/mysql/mysql.pid ended
  

но я не понимаю, что это такое. Но я видел в этой строке

 > InnoDB: Error: could not open single-table tablespace file ./racehistory/users.ibd
  

это не имя моей базы данных, мое имя базы данных RaceHistory . Возможно, проблема здесь, но в этом случае я не знаю, как изменить MySQL, в phpMyAdmin я создал базу данных с именем: RaceHistory .
Я попытался изменить порт MySQL, я попробовал с 3300, 3306 и случайными портами, с 3300 это сработало на мгновение, и снова произошел сбой.
Так что, если у вас есть какие-либо идеи!
Спасибо! (И извините за мой английский)

РЕДАКТИРОВАТЬ: я пытаюсь запустить apache и mysql с помощью терминала, поэтому я зашел в /MAMP/ bin и делаю sh start.sh , он запускается для apache, но для mysql у меня есть это:

 161018 15:45:39 mysqld_safe mysqld from pid file /Applications/MAMP/tmp/mysql/mysql.pid ended
  

Итак, я перешел в tmp / mysql, и у меня нет файла mysql.pid!

Ваше сообщение об ошибке дает некоторые довольно хорошие подсказки, что делать дальше.
