修改MySQL密码 set password for 'root'@'localhost'=password('root'); 远程连接 创建新用户 注意：root账号在debian系统中无法直接开启远程连接，所以需要新建mysql用户；
CREATE USER 'your_username'@'%' IDENTIFIED BY 'your_password'; 将your_username替换为你想要创建的用户名，将your_password替换为你想要设置的密码。
新用户授权 GRANT ALL PRIVILEGES ON . TO 'your_username'@'%' WITH GRANT OPTION; 刷新MySQL权限 FLUSH PRIVILEGES;
