How do I establish an HTTPS connection from client by the server public key to that specific server?

Question

I have a client-server model.

The server generated a key pair and shipped public keys to all the clients. In order to confirm the server is the real server I gonna to make connection to, I want to establish an HTTPS connection by the server public key to that specific server.

How can I do that? Or is there any better way to authenticate the server?

This is the first time I ask at stackoverflow. So, if you have any suggestion please don't hesitate to tell me. Thank you.

我认为我需要的是“证书和公钥固定”这个词。
