However, in this case, you still need to use the user for remote connection, therefore, to allow remote access, you need to perform the following operations: 1. Allow the root user to log on Remotely Anywhere and have any operation permissions on all databases. The specific operations are as follows: log ON to mysql: mysql-u root-p "youpassword" as the root user ON the local machine for authorization: mysql> grant all privileges on *. * TO 'root' @ '%' identified by 'youpassword' with grant option; overload authorization table: flush privileges; exit mysql database: exit 2. Allow the root user to log on remotely from a specific IP address and have any operation permissions on all databases. The specific operation is as follows: log on to mysql with the root user on the local machine first: m Ysql-u root-p "youpassword": grant all privileges on *. * TO root @ "172.16.16.152" identified by "youpassword" with grant option; overload authorization table: flush privileges; exit mysql database: exit 3.
