Я не могу запустить MySQL на Linux - Ошибка mysqld_safe

Question

Я нашел на многих форумах в Интернете, но я не нашел своего решения. При запуске MySQL службы в Linux Ubuntu Server 12.04, я получаю эту ошибку:

root@stroke:/# mysqld_safe & 
[1] 5789 
root@stroke:/# 131001 10:12:29 mysqld_safe Logging to syslog. 
131001 10:12:29 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql 
131001 10:12:29 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended 

Я уже дал разрешение на MySQL папки, я также пытался создать новый пароль для корневого MySQL , Но пока ничего не получилось.

Спасибо за помощь.

Некоторая информация:

root@stroke:/# /etc/init.d/mysql start 
Rather than invoking init scripts through /etc/init.d, use the service(8) 
utility, e.g. service mysql start 

Since the script you are attempting to invoke has been converted to an 
Upstart job, you may also use the start(8) utility, e.g. start mysql 
start: Job failed to start

Answer 1

MySQL работает под своим собственным пользователем, поэтому его запуск под root не является разумным решением. И теперь, когда вы уже пробовали, что некоторые из ваших файлов могут принадлежать root, чтобы служба не запускалась.

• Проверьте, что весь каталог с базой данных MySQL принадлежит mysql.
• Попробуйте начать сервис с помощью выскочки: start mysql
• В каталоге базы данных MySQL проверьте файл журнала.

Answer 2

ли порт 3306 уже используется? Попытка:

netstat -an | grep 3306 

Редактировать: как вы начинаете MySQL? Попытка:

/etc/init.d/mysql start
