PHP remote connection to MySQL

I. Table modification method

It may be that your account is not allowed to log on remotely, but only on localhost. In this case, you only need to use 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;

Mysql> flush rivileges

 

Ii. 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 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;

 

3. The method is the same as method 2, but it is only run in cmd.

Run the following command on the machine where MySQL is installed:

1. D:/MySQL/bin/> mysql-H localhost-u Root

// You can access the MySQL server.

2. mysql> grant all privileges on *. * To 'root' @ '%' with grant option

// Grant data access permissions to any host

3. mysql> flush privileges

// The modification takes effect.

4. mysql> exit

// Exit the MySQL server

In this way, you can log on to any other host as the root user.
