Solve the Problem of MySQL remote connection authorization

After MySQL is installed, the server cannot be remotely connected. The following message is displayed:

Host '1970. 181.149.27 'is not allowed to connect to this MySQL Server

Solution:
1. Change Table Method

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-pvmware

Mysql> use MySQL;

Mysql> Update user set host = '%' where user = 'root ';

Mysql> select host, user from user;

2. Authorization Law

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 with the IP address 220.181.149.27, and use mypassword as the password
Grant all privileges on *. * To 'root' @ '220. 181.149.27 'identified by 'mypassword' with grant option;

Grant all privileges on *. * To 'root' @ '192. 181.149.27 'identified by '20140901' with grant option;
