解决mysql“Access denied for user 'root'@'loc..

大致意思就是给mysql中的root用户添加密码 （密码我就用******表示）

[ooo@localhost ~]$ mysqladmin -u root -p ******
Enter password:
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: YES)'

[ooo@localhost ~]$ sudo /etc/init.d/mysqld stop
停止 MySQL： [确定]


[ooo@localhost ~]$ sudo mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
[1] 17641

[ooo@localhost ~]$ nohup: ignoring input and redirecting stderr to stdout
Starting mysqld daemon with databases from /var/lib/mysql
mysql -u root mysql （注意这里要自己输入 没提示的）
mysql> UPDATE user SET Password=PASSWORD('******') where USER='root';
