How to deploy website on my own server?

Due to china mainland network speed,  I want to deploy website on my own server.
Could you give me some tutorial about how to deploy it?

Another question is: How could I deploy this web site under some prefix?
e.g. I want to access my site in this url:  `https://example.com/somesubpath/` instead of root path: `https://example.com/`
I got some error when try this.
