Mysql远程连接报错:Host is not allowed to connect to this MySQL server

原因:MySQL为设置远程访问权限。
在该服务器终端进行更新权限

第一步、登录mysql

[root@iZwz9ge5ckboywt63qr7qgZ ~]# mysql -u root -p

输入密码

Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 492
Server version: 5.7.39-log Source distribution

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

第二步、使用数据库

mysql> use mysql

结果

Database changed

第三步、更新用户访问主机数据

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

结果

Query OK, 1 row affected (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 0

最后一步,更新权限。(要加 符号 ;)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.04 sec)
