mysql cannot connect remotely Can't connect to MySQL server on 'xxx.xxx.xxx.xxx' (10060 "Unknown error")

Many friends have installed mysql on their servers, and then found that they have turned on the mysql service in the server, and then turned off the firewall, but they can't connect, and then use the user to log in. The password is also entered correctly, but it isCan't connect, and prompts this error

At this time, it was found that because the host only set the local connection, it needs to be modified to connect

Enter the database

mysql -u root -p

Enter the root password to enter the database

use mysql;

Use this library of mysql

Check the user's host

select host,user from user;

At this time, I found that the host of my adai user can only be connected locally. At this time, I need to change it to %, so that others can use this account to connect

update user set host='%' where user='adai';

Let's check again

The modification has been completed at this time, and the connection can be successfully connected at this time
