ubuntu - 远程服务器不小心更改了sshd配置，关闭了ssh访问权限，现在访问不了服务器了，应该怎么办才好

Question

如题，刚刚在操作服务器的时候，更改了sshd的配置，现在ssh远程登录提示没权限，应该怎么办才好。。

Answer 1

If it is a cloud server, such as Alibaba Cloud or linode, you can generally access the terminal directly through the console.
If it is a self-built cloud server, such as ESXi, it can be accessed through the vcenter management machine.
If it is a physical machine directly, then see Check to see if there is a remote service such as ilo configured. You can directly connect to the terminal through the remote service.

Answer 2

Where is the remote server located? If you are purchasing a cloud host, does the service provider have relevant control rights? If it is managed, it probably needs to be handled manually.
