message from server: "Host ‘192.168.1.152’ is not allowed to connect to this MySQL server
在连接本机的mysql 数据库时，配置连接信息，连接发生错误，
message from server: "Host '192.168.1.152' is not allowed to connect to this MySQL server
But changing the IP address to localhost can connect to the MySQL database normally.
Solution:
Execute the following command in Navicat
select host from user where user = 'root'
It is found that the value of host is localhost,
so it is necessary to modify its value:
update user set host='%' where user = 'root'
After the modification is completed, execute
flush privileges
The modified content will take effect. When you configure it again, you can connect to the MySQL database normally with the IP address or localhost.
