my.cnf (my.ini on windows)

#Replace xxx with your IP Address 
bind-address        = xxx.xxx.xxx.xxx

OR

sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf


then

CREATE USER 'myuser'@'localhost' IDENTIFIED BY 'mypass';
CREATE USER 'myuser'@'%' IDENTIFIED BY 'mypass';

Then

GRANT ALL ON database_name.* TO 'myuser'@'localhost';
GRANT ALL ON database_name.* TO 'myuser'@'%';

SELECT User, Host FROM mysql.user;

檢查 server 上開啟的 listen port:

netstat --tcp --listen --numeric-ports
