How to grant remote access permissions to mysql server for user?

Question

If I do SHOW GRANTS in my mysql database I get

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' 
    IDENTIFIED BY PASSWORD 'some_characters' 
    WITH GRANT OPTION

If I am not mistaken, root@localhost means that user root can access the server only from localhost. How do I tell MySQL to grant root the permission to access this mysql server from every other machine (in the same network), too?

Answer 1

This grants root access with the same password from any machine in *.example.com:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%.example.com' 
    IDENTIFIED BY 'some_characters' 
    WITH GRANT OPTION;
FLUSH PRIVILEGES;

If name resolution is not going to work, you may also grant access by IP or subnet:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.%'
    IDENTIFIED BY 'some_characters'  
    WITH GRANT OPTION;
FLUSH PRIVILEGES;
