Mysql 8 remote access

1. Delete or comment the bind_address parameter from the my.ini file.

(The file name is different depend on the OS. On Linux my.ini is
actually my.cnf located in directory /etc/mysql/)

2. Restart the service.

3. Create the root user (yes, a new user because what exists is ‘root@localhost’ which is local access only):

   CREATE USER 'root'@'%' IDENTIFIED BY '123';

4. Give the privileges:

   GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';

For DBA user, add WITH GRANT OPTION at the end.

e.g. CREATE USER 'root'@'%' IDENTIFIED BY '123' WITH GRANT OPTION;

Because it does not work CREATE with GRANT?

MySQL 8 can no longer create a user with GRANT, so there is an error in IDENTIFIED BY '123' if you try to use it with GRANT, which is the most common error.
