我是个新手求大侠们指点:
刚弄的云服务器 今天ssh登录时偶然发现root密码登录后提示:
Last failed login: Fri Dec 15 10:41:37 CST 2017 from 51.15.220.221 on ssh:notty
There were 49 failed login attempts since the last successful login.
请问这是安全隐患吗?是怎么形成的?需要怎么处理?
我忘了我的根密码..。然后我停止mysql服务器并使用skip-grant-tables;重新启动它,我通过以下方式更改了根密码
mysql>update mysql.user set password='12345' where user='root';
mysql> select user,password from mysql.user;
我得到的是::
+------+-------------------------------------------+
| user | password
