MYSQL登录错误：mysqladmin: connect to server at 'localhost' failed
无法修改密码用 service mysqld stopmysqld_safe --skip-grant-tables &输入 mysql -uroot -p 回车进入>use mysql;> update user set password=PASSWORD("newpass")where user="root"; 更改密码为 newpassord> flush privileges; 更新权限> quit 退出
service mysqld restartmysql -uroot -p新密码进入
===========================================================
二，忘记本地root的登录密码
解决过程：
1、编辑/etc/my.cnf
在[mysqld] 配置部分添加一行
skip-grant-tables
2、保存后重启mysql
[root@localhost etc]# service mysqld restartShutting down MySQL. [ OK ]Starting MySQL. [ OK ]3、登录数据库重新设置root密码
[root@localhost ~]# mysql -uroot -p mysqlEnter password:
直接回车进入

4、删除/etc/my.cnf文件中添加的“skip-grant-tables”行，重启mysql；
用新设的密码就能正常登录了；
