Solve:

Plan One: Change the table:

Use MySQL, select User,host,password from user;

Update user Set host = '% ' where user= ' root ';

Programme II: Authorization Law:

For example, if you want to myuser use MyPassword to connect to a MySQL server from any host.
GRANT all privileges on * * to ' myuser ' @ ' percent ' identified by ' MyPassword ' with GRANT OPTION;
If you want to allow users to connect to the MySQL server from a host myuser IP 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;
