Two major solutions to problems in MySQL remote connection

This article describes how to solve the MySQL remote connection problem. We all know that the MySQL remote connection problem is often encountered in actual operations, so it is better for you to know more about it. I hope it will help you in this regard.

Solution:

1. ALTER 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 -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 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 '123456' WITH GRANT OPTION;  
  
  
mysql> flush privileges;
