Is not allowed to connect to this MySQL Server
Keyword: is not allowed to connect to this MySQL Server
If you want to connect to your MySQL instance, this error occurs:

Error 1130: Host '192. 168.1.3 'is not allowed to connect to this MySQL Server

Solution:
1. Change the table. It may be that your account is not allowed to log on remotely, but only on localhost. At this time, you only need to log in to MySQL on the computer of localhost, and change the "host" entry in the "user" table in the "MySQL" database to "%" from "localhost"

Mysql-u root-pvmwaremysql> use MySQL; mysql> Update user set host = '%' where user = 'root'; mysql> select host, user from user;

2. Authorization method. For example, if you want myuser to use mypassword to connect to the MySQL server from any host.

Grant all privileges on *. * To 'myuser' @ '%' identified by 'mypassword' with grant option;
If you want to allow myuser to connect to the MySQL server from a host whose IP address is 192.168.1.3, and use mypassword as the password
Grant all privileges on *. * To 'root' @ '192. 168.1.3 'identified by 'mypassword' with grant option;

Grant all privileges on *. * To 'root' @ '10. 10.40.54 'identified by '123' with grant option;
