nginx和星号server_name？

Question

Is there a way to proxy all traffic to a certain server unless the domain is something different?

Basically a * for the server_name property?

server {
  listen 80;
  server_name foo.com
}

server {
  listen 80;
  server_name *
}

Or, is there a way to set a "default" server, and then it would use it if none of the other specific server configs match?

Answer 1

You can't use * for server_name . From the documentation :

A wildcard name may contain an asterisk only on the name's start or end, and only on a dot border.

However, you can use a regular expression:

server {
    server_name   ~^(www\.)?(.+)$;

    location / {
        root   /sites/$2;
    }
}

Answer 2

As @Valery Viktorovsky's answer says, you can't use a * for server_name . You can designate a server block as the "default" to receive all requests which don't match any others. See this post for an explanation. It would look like this:

server {
    listen 80 default_server;
    server_name wontmatch.com; # but it doesn't matter
}

See the docs for server_name for more.

只是一个快速更新......根据文档，通配符现在可以正常工作： http ： //nginx.org/en/docs/http/server_names.html

Answer 4

FYI, for those like me who were looking for something a little different, the following configuration will listen and respond to all port 80 request whether you use IP or URL (AKA everything):

server {
    listen 80 default_server;
    server_name _;
...
}

Taken from: http://nginx.org/en/docs/http/server_names.html

In catch-all server examples the strange name “_” can be seen:

server { listen 80 default_server; server_name _; return 444; } There is nothing special about this name,...

You will get errors on sudo service nginx restart or ... start while /etc/nginx/sites-enabled/default symbolic link is still active since it uses the same matching pattern. Simply remove that link and everything should work.
