nginx - How to automatically resolve the pointing URL when creating a second-level domain name for a website?

Question

Previous steps:

1. Create a second-level domain name in dns
2. Second-level domain name specifies A record binding
3. Server binding second-level domain name

Current needs:

1. The user creates the domain name xxx.example.com on the website
2. Accessing this domain name automatically jumps to example.com/xxx
3. How to implement this?

Answer 1

Use pan-parsing processing. First, parse *.example.com to example.com, so that all subdomain names will point to example.com. Next, judge the request, take out the * part, and make the corresponding jump (for example, use $_SERVER['SERVER_NAME']).

Answer 2

nginx should be able to do it, and it’s a good idea 0.0

server{
    listen 80;
    server_name sec-domain.domain.com;
    location / {
        proxy_pass domain.com/sec-domain;
    }
}

Answer 3

1. Domain name pan-resolution
2.apache uses mod_rewrite
