SSH主机密钥验证失败而未能成功建立连接。预期服务器的SSH密钥会发生变化，或者你更换了服务器，就需要更新本地的`known_hosts`文件。
解决
以下是日志中的一些关键信息和可能的解决方案：
关键信息：
-
**SSH Resolver调用**：Remote - SSH扩展尝试连接到IP地址`27.23.24.103`。
-
**SSH客户端路径**：VSCode找到了`C:\Windows\System32\OpenSSH\ssh.exe`作为SSH客户端。
-
**SSH连接命令**：使用了以下命令尝试建立SSH连接：
```
"C:\Windows\System32\OpenSSH\ssh.exe" -T -D 60388 "27.23.24.103" bash
```
-
**主机密钥变更警告**：VSCode提示远程主机的RSA密钥发生了变化，这通常意味着本地的`known_hosts`文件中的密钥与远程主机当前的密钥不匹配。
-
**连接失败**：由于主机密钥验证失败，SSH连接尝试失败。
-
**取消连接**：在尝试安装和启动服务器时，连接被取消。
可能的解决方案：
-
**检查SSH密钥**：如果你预期服务器的SSH密钥会发生变化，或者你更换了服务器，你需要更新本地的`known_hosts`文件。
-
**更新`known_hosts`**：你可以通过以下方式更新或删除本地的密钥记录：
-
手动打开`C:\Users\Administrator\.ssh\known_hosts`文件，找到对应的主机条目并删除。
-
或者，使用SSH命令连接时，使用`-o StrictHostKeyChecking=no`参数来跳过密钥检查（这会降低安全性，因为它容易受到中间人攻击）。
-
**确保SSH客户端正确安装**：确保`ssh.exe`位于指定路径，并且可以正常工作。
-
**检查网络连接**：确保你的网络连接可以到达远程服务器的IP地址，并且没有防火墙或路由器设置阻止了SSH连接。
-
**检查服务器状态**：确认远程服务器已经启动并且SSH服务正在运行。
-
**检查SSH配置**：确认VSCode的SSH配置没有错误，包括用户名、端口以及任何需要的密钥或密码。
-
**查看详细日志**：如果问题仍然存在，你可以通过增加Remote - SSH扩展的日志级别来获取更详细的信息，以便进一步调试。
-
**联系系统管理员**：如果你不确定如何处理SSH密钥更改的问题，联系服务器的系统管理员获取帮助。
注意
跳过主机密钥检查会降低安全性，因此只在你信任网络环境和远程主机时才使用。在生产环境中，始终确保使用最新的密钥，并且不要跳过密钥检查。
