安装mysql-server后不能启动

[ilttv]

apt安装mysql-server后，出现下面的错误 /usr/bin/mysqladmin: connect to server at 'localhost' failed error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111)' Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists! 不知道该怎么解决啊
