Nginx to apache reverse proxy, instruct use of unix sockets

  • 772

My Nginx reverse proxy works on the same machine as the webserver(apache) as follows 

server {  server_name site.net;
    location / {
        proxy_pass http://localhost:82;
        proxy_set_header   Host             $host;
        proxy_set_header   X-Real-IP        $remote_addr;

    }
}

Now instead of using TCP connections to the backend apache, how can I tune it to use unix sockets?

Edit:
Can someone help with the full flow, instructing apache to listen on unix sockets too

nginx

  1. While you most likely could set Nginx to proxy redirect to a socket using unix:/path/to/socket syntax, Apache Listen directive only accepts IPv4 or IPv6, so as far as I know you can't get Apache to listen on an unix socket.

  2. You need to define an upstream like this:

    upstream upstream_name {
        server unix:/path/to/socket fail_timeout=0;
}

    And then set proxy_pass to reference that upstream by name, i.e.,

    proxy_pass http://upstream_name
