无法启动mysql服务

我无法从我的Ubuntu服务器重新启动我的MySQL服务。 这是错误:

mysql.service - LSB: Start and stop the mysql database server daemon Loaded: loaded (/etc/init.d/mysql; bad; vendor preset: enabled) Active: failed (Result: exit-code) since mer. 2016-06-08 17:31:06 CEST; 54s ago Docs: man:systemd-sysv-generator(8) Process: 4087 ExecStart=/etc/init.d/mysql start (code=exited, status=1/FAILURE) juin 08 17:31:06 SRV-OVH-GIC03-V /etc/init.d/mysql[4569]: 0 processes alive and '/usr/bin/mysqladmin --defaults-file=/etc/mysql/debian.cnf ping' resulted in juin 08 17:31:06 SRV-OVH-GIC03-V /etc/init.d/mysql[4569]: [61B blob data] juin 08 17:31:06 SRV-OVH-GIC03-V /etc/init.d/mysql[4569]: error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2 "No such file or directory")' juin 08 17:31:06 SRV-OVH-GIC03-V /etc/init.d/mysql[4569]: Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists! juin 08 17:31:06 SRV-OVH-GIC03-V /etc/init.d/mysql[4569]: juin 08 17:31:06 SRV-OVH-GIC03-V mysql[4087]: ...fail! juin 08 17:31:06 SRV-OVH-GIC03-V systemd[1]: mysql.service: Control process exited, code=exited status=1 juin 08 17:31:06 SRV-OVH-GIC03-V systemd[1]: Failed to start LSB: Start and stop the mysql database server daemon. juin 08 17:31:06 SRV-OVH-GIC03-V systemd[1]: mysql.service: Unit entered failed state. juin 08 17:31:06 SRV-OVH-GIC03-V systemd[1]: mysql.service: Failed with result 'exit-code'. 

我试着重新启动mysql服务(sudo服务mysql重启)。 套接字似乎缺less,所以我寻找如何创build它,我find的所有解决scheme是重新启动mysql服务…我怎样才能解决这个错误?

运行mysqld --help并检查,如果它报告任何configuration问题

检查/var/log/mysql

尝试直接运行它并检查错误:

 mkdir /var/run/mysqld/ chown mysql: /var/run/mysqld/ mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --socket=/var/run/mysqld/mysqld.sock
