# mysql 被黑客攻击了 惨痛教训
|
||
|
|
**今天鼓捣c++ 项目的时候 需要用下nacos 准备docker 安装个发现数据库被黑客攻击了太惨了，还好数据没丢只是 把我的root 权限给改了。
|
||
|
|
自己的mysql 密码太简单了，以后要把密码复杂化**
|
||
|
|
下面解决方法
|
||
|
|
先用本地用户登录mysql
|
||
|
|
赋予远程账号全部权限；
|
||
|
|
刷新配置；
|
||
|
|
修改远程账号密码
|
||
|
|
刷新配置；
|
||
|
|
|
||
|
|
|
||
|
|
```
|
||
|
|
mysql> grant all on *.* to root@'%';
|
||
|
|
Query OK, 0 rows affected (0.00 sec)
|
||
|
|
|
||
|
|
mysql> flush privileges;
|
||
|
|
Query OK, 0 rows affected (0.00 sec)
|
||
|
|
|
||
|
|
mysql> ALTER USER 'root'@'%' IDENTIFIED BY 'xxxxxx';
|
||
|
