Проблема с MySQL

Если не используется InnoDB - отключите его с помощью skip-innodb добавив его в секцию [mysqld]

Соответственно, при отключении скорее всего появится сообщение "Unknown table engine 'InnoDB'".

Himiko:
можете запустить команду:
mysql -u root -pПАРОЛЬ_ROOT_ОТ_MYSQL -e "select engine from information_schema.tables" | sort | uniq -c
Покажет, какие типы таблиц у вас используются.

Himiko:
Может есть смысл вообще выключить его. (skip-innodb)

-------- Recommendations -----------------------------------------------------
General recommendations:
Run OPTIMIZE TABLE to defragment tables for better performance
MySQL started within last 24 hours - recommendations may be inaccurate
Enable the slow query log to troubleshoot bad queries
Adjust your join queries to always utilize indexes
Set thread_cache_size to 4 as a starting value
Increase table_cache gradually to avoid file descriptor limits
Variables to adjust:
query_cache_size (>= 8M)
join_buffer_size (> 128.0K, or always use indexes with joins)
thread_cache_size (start at 4)
table_cache (> 64)
