首先停掉mysql服务，在/etc/f中添加skip-grant-tables，同时可以添加skip-networking选项来禁用网络功能，防止这时其他人通过网络连接到数据库
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
symbolic-links=0
skip-grant-tables #添加这一行
启动服务，进入数据库
MariaDB [(none)]> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
[emailprotected]，没有就用update添加
MariaDB [mysql]> select host,user,password from user;
+-----------------------+------+-------------------------------------------+
| host | user | password |
+-----------------------+------+-------------------------------------------+
| % | LEE | *E6CC90B878B948C35E92B003C792C46C58C4AF40 |
| % | root | *E6CC90B878B948C35E92B003C792C46C58C4AF40 |
| localhost | root | |
| localhost.localdomain | | |
| 127.0.0.1 | root | |

#更新数据库
MariaDB [mysql]> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
在之后退出数据库，把刚才改的配置文件还原回来，重启数据库就好了。
