【1】故障信息
Starting MySQL. ERROR! The server quit without updating PID file(xxx/x.pid)
[ERROR] Could not create unix socket lock file /usr/local/mysql/sock/mysql.sock.lock.
2018-11-30T03:01:12.764913Z 0 [ERROR] Unable to setup unix socket lock file.
2018-11-30T03:01:12.764928Z 0 [ERROR] Aborting
【2】解决办法
比如我这里报错是:Starting MySQL. ERROR! The server quit without updating PID file (/data/mysql/mysql_3306/data/db4.pid).
一般是权限问题,给你报错的目录加个权限即可。
chown -R mysql:mysql /data/mysql/mysql_3306
chmod 755 -R /data/mysql/mysql_3306
这样就解决了
