Nginx重写-仅重定向到一个域

Question

I am looking to redirect all requests that match http://s.domain.com to redirect to http://domain-new.com

I have the following and it seems to redirect all requests to the second domain. I would only like to redirect on an exact match.

 if ($request_uri ~ "s.domain.com"){
       rewrite ^ http://domain-new.com;
     }

You can create a server block for the subdomain and redirect that to the new domain

server {
    listen 80;
    server_name s.domain.com;
    rewrite ^ http://domain-new.com$request_uri? permanent;
}

This should work for only redirecting the index:

server {
    listen 80;
    server_name s.domain.com;
    # for index.xyz pages
    location ~ ^/index\..+$ {
        rewrite ^ http://domain-new.com$request_uri? permanent;
    }
    # for pages with index left out
    location / {
        rewrite ^/$ http://domain-new.com permanent;
    }
}
