串連mysql時報：message from server: "Host '192.168.76.89' is not allowed to connect to this MySQL server

處理方案：

1、先用localhost方式串連到MySQL資料庫，然後使用MySQL內建的資料庫mysql;

          use mysql； 

 

2、執行：select host from user where user = ‘root‘;  發現，host的值就是localhost。

     所以將它的值改掉：update user set host=‘%‘ where user = ‘root‘; 

 

3、修改完成後，執行：flush privileges;  

     將修改內容生效，再次配置時，用IP地址或者localhost 就都能正常串連到MySQL資料庫了。

操作如下：

mysql> 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
