=========完整思路可参考如下============

https://www.cnblogs.com/dtiove/p/5716591.html

①：netstat -an|grep 3306查看本机和防火墙是否开放3306端口

来查看mysql默认的端口3306是否开启，允许哪个ip使用，如果你发现，前面有127.0.0.1，就说明，3306端口只能本机ip使用

②：打开mysql配置文件vi /etc/mysql/mysql.conf.d/mysqld.cnf

将bind-address = 127.0.0.1注销​

③：进入mysql，对远程用户进行授权，

grant all privileges on *.* to 'root'@'%' identified by 'xxxxxx';

这里的root 是你远程登录的用户，xxxxxx是你登录使用的密码，然后可以在mysql数据 表中查看到你这个用户已经被添加到user表中
