  • 连接mysql时报:message from server: "Host '192.168.76.89' is not allowed to connect to this MySQL server 处理方案

    1、先用localhost方式连接到MySQL数据库,然后使用MySQL自带的数据库mysql;

              use mysql; 

    2、执行:select host from user where user = 'root';  发现,host的值就是localhost。

         所以将它的值改掉:update user set host='%' where user = 'root'; 

    3、修改完成后,执行:flush privileges;  

         将修改内容生效,再次配置时,用IP地址或者localhost 就都能正常连接到MySQL数据库了。

    操作如下:

    mysql> use mysql

    You can turn off this feature to get a quicker startup with -A

    Database changed

    mysql> select host from user where user = 'root';

    +-----------+

    | host      |

    +-----------+

    | localhost |

    +-----------+

    1 row in set (0.00 sec)

    mysql> update user set host='%' where user = 'root';

    Query OK, 1 row affected (0.00 sec)

    Rows matched: 1  Changed: 1  Warnings: 0

    mysql> select host from user where user = 'root';

    +------+

    | host |

    +------+

    | %    |

    +------+

    1 row in set (0.00 sec)

    mysql> flush privileges;

    Query OK, 0 rows affected (0.00 sec)

    mysql>
