MySQL remote connection settings

If the web and database are not on the same server, the MySQL server must allow remote connections to run the website properly.
There are two ways to set the remote connection of MySQL:

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 'myuser' @ '192. 168.1.3 'identified by 'mypassword' with grant option;
