    以下操作命令和方法均是在 mysql5.6.24 版本上,其他版本略有差异。

    一、登录mysql

    [root@db-1-198 ~]# mysql -h127.0.0.1 -uroot -p'DbMingX28' -P3306 -S /tmp/mysql3306.sock

    mysql>

    二、查看现有的数据库实例

    mysql> show databases;
    +------------------------+
    | Database         |
    +------------------------+
    | information_schema |
    | mysql |
    | performance_schema |
    | test |
    +------------------------+
    4 rows in set (0.01 sec)

    三、创建数据库实例

    mysql> show databases;
    +------------------------+
    | Database |
    +------------------------+
    | information_schema |
    | mysql |
    | performance_schema |
    | test |
    +------------------------+
    4 rows in set (0.01 sec)

    四、创建用户并授权该实例的所有权限给新创建的用户

    mysql> grant all on wangming.* to 'wmuser'@'192.168.1.%' identified by 'Pz4p6uA13K';
    Query OK, 0 rows affected (0.00 sec)
    
    mysql> flush privileges;
    Query OK, 0 rows affected (0.03 sec)
    
    mysql> show grants for 'wmuser'@'192.168.1.%';
    +-----------------------------------------------------------------------------------------------------------------------+
    | Grants for wmuser@192.168.1.% |
    +-----------------------------------------------------------------------------------------------------------------------+
    | GRANT USAGE ON *.* TO 'wmuser'@'192.168.1.%' IDENTIFIED BY PASSWORD '*4C1597C9C4060CCA85B46F5851DFEEEAF2BE459F' |
    | GRANT ALL PRIVILEGES ON `wmuser`.* TO 'wmuser'@'192.168.1.%' |
    +-----------------------------------------------------------------------------------------------------------------------+
    2 rows in set (0.00 sec)

    五、使用新创建的用户测试登录

    [root@db-1-198 ~]# mysql -h192.168.1.198 -uwmuser -p'Pz4p6uA13K' -P3306 -S /tmp/mysql3306.sock
    Warning: Using a password on the command line interface can be insecure.

    mysql>
