就是按照找到的教程 但是在my.cnf 中找不到mysql 那就看看它包含的目录里面有一个server.cnf 在这个文件中找到了mysql的部分那就添加一下skip-grant-tables到里面

然后

重启MariaDB

进入到mysql

mysql

Welcome to the MariaDB monitor. Commands end with ; or \g.

Your MariaDB connection id is 5

Server version: 10.1.13-MariaDB Source distribution

Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

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

Database changed

MariaDB [mysql]> UPDATE user SET Password = password('123456') WHERE User = 'root';

Query OK, 1 row affected (0.05 sec)

Rows matched: 1 Changed: 1 Warnings: 0

MariaDB [mysql]> flush privileges;

Query OK, 0 rows affected (0.01 sec)

MariaDB [mysql]> quit

这样再到前面的目录里面删除之前加进去的东西就好了

继续重启MariaDB服务
