今天在启动MysqL时出现以下问题：
[root@www ~]# MysqL -u root -p Enter password: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
网上的答案是各种各样的，最终解决问题的方法总结为以下，好多都是没有设置初始密码造成此问题的。
解决方法如下：
[root@www ~]# service MysqLd stop #先关闭MysqL服务 Stopping MysqLd: [ OK ] [root@www ~]# MysqL ERROR 2002 (HY000): Can't connect to local MysqL server through socket '/var/lib/MysqL/MysqL.sock' (2) [root@www ~]# MysqL -u root -p #关闭服务后又出现如下问题 Enter password: ERROR 2002 (HY000): Can't connect to local MysqL server through socket '/var/lib/MysqL/MysqL.sock' (2) [root@www ~]# MysqL -u root MysqL #键入此命令进入MysqL Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Welcome to the MysqL monitor.
