#MySQL #Socket

本文记录了一次MySQL服务启动失败的故障排查过程，主要错误为尝试启动MySQL守护进程时超时，连接本地MySQL服务器失败，提示无法通过'/var/lib/mysql/mysql.sock'套接字连接到服务器。检查mysqld是否正在运行及该套接字文件是否存在。

# service mysqld start
Timeout error occurred trying to start MySQL Daemon.
启动 MySQL： [失败]

# mysqladmin status
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/var/lib/mysql/mysql.sock' exists!

# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
