1.建个数据库用于远程访问：

CREATE DATABASE db_firm DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

2.配置一个用户用于远程登录：

CREATE USER ‘user1‘@‘%‘ IDENTIFIED BY ‘123‘;

3.授予用户权限：

GRANT ALL PRIVILEGES ON db_firm.* TO ‘user1‘@‘%‘;

FLUSH PRIVILEGES;

4.远程登录：

mysql -u user1 -p123 -h 168.171.127.71

mysql 远程连接数据库
