连接被拒绝，我无法进入我的服务器

Question

我不确定我的网站是否被黑客入侵，或者有一个与服务器相关的错误。我的网站运行良好，自从我发表了它，昨天我访问了它，它说，连接拒绝。我通知了我的主机提供商，他们告诉我要创建一个新的数据库连接，当我打开phpMyAdmin时，我收到一个奇怪的错误，上面写着：

Warning in ./libraries/plugins/auth/AuthenticationCpanel.php#629
mysqli_connect(): (HY000/2002): Can't connect to local MySQL server 
through socket '/var/lib/mysql/mysql.sock' (2)

当我试图将ssh插入我的服务器时，我会得到以下错误：

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Add correct host key in /c/Users/Game330/.ssh/known_hosts to get rid of this mes   sage.
Offending RSA key in /c/Users/Game330/.ssh/known_hosts:1
RSA host key for [wesocular.com]:60504 has changed and you have requested strict    checking.

有什么问题吗？

Answer 1

如果您读取错误消息，您将看到原因：The RSA host key for [wesocular.com]:60504 has changed, and the key for the corresponding IP address [46.105.40.12]:60504 is unknown.

然后是如何修复它的解决方案：Add correct host key in /c/Users/Game330/.ssh/known_hosts to get rid of this message. Offending RSA key in /c/Users/Game330/.ssh/known_hosts:1

因此，您可以删除/c/Users/Game330/.ssh/known_hosts文件中第1行中的键，并再次尝试通过SSH登录。
