1. MySql安裝教程

https://dev.mysql.com/doc/refman/5.7/en/linux-installation-yum-repo.html

默認情況下mysq的 root用戶是不能遠程連接的

2. 查看linux防火墻是否開放3306端口

3. 添加防火墻例外

4. 重啟防火墻

5. 創建遠程連接用戶並授權

mysql> select host,user,password from mysql.user;

創建用戶

create user test identified by ‘123456‘;

授權

grant all privileges on *
 
.* to ‘test‘@‘%‘identified by ‘123456‘ with grant option;
flush privileges;

修改用戶密碼

update mysql.user set password=password(‘新密碼‘) where User="test" and Host="localhost";

刪除用戶

delete from user where User=‘test‘ and Host=‘localhost‘;

linux下mysql允許遠程連接
