Linux下启动mysql

[root@training ~]# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111)

原因是mysql server没有启动

[root@training ~]# /etc/rc.d/init.d/mysqld status
mysqld is stopped
[root@training ~]# /etc/rc.d/init.d/mysqld start
Starting mysqld:                                           [  OK  ]

[root@training ~]# mysql -uroot -p123456
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
