2、重新连接mysql：
-
[root@zzs171 opt]
# /usr/bin/mysql -u root -p
-
Enter password:
3、修改mysql的root的密码：
进入mysql客户端之后，show databases; 会提醒先修改密码：
-
mysql> show databases;
-
ERROR

using ALTER USER statement before executing
this statement.
-
SET

'localhost' =
PASSWORD(

-
-

-
mysql>
SET PASSWORD
FOR
'root'@
'localhost' = PASSWORD(

-

【其他补充】
网上还有几种方案，但是都不行。例如：
-
方案一：
-
mysqladmin -u root password 123456，结果提示错误：error: 'Access denied for user 'root'@'localhost' (using password: NO)'
-
-
方案二：
-
用mysqld_safe skip-
grant-
tables进入mysql，然后
sql语句修改root密码，还是提示错误：-bash: mysqld_safe: command
not
found
