Hosting two Node.JS apps on same domain

问题

I have two node js applications I am running on the same box and I would like for it to run the first node js app for all routing except if the url is www.domain.com/blog to go to the other node js application. Is this even possible with this setup or do I have to setup subdomains and use nginx or something?

You can achieve this using nginx as a reverse proxy.

Assuming you have your blog node process running on port 3000 and another node process on 3001 a simple config would look like;

upstream blog {
   server 127.0.0.1:3000;
}


upstream other {
   server 127.0.0.1:3001;
}


server {
    listen 80;
    server_name www.domain.com;

    location /blog  {
        proxy_pass          http://blog;
        proxy_http_version  1.1;
        proxy_set_header    Host                $http_host;
        proxy_set_header    Upgrade             $http_upgrade;
        proxy_set_header    Connection          "Upgrade";
        proxy_set_header    X-Real-IP           $proxy_protocol_addr;
        proxy_set_header    X-Forwarded-For     $proxy_add_x_forwarded_for;
        proxy_set_header    X-Forwarded-Proto   tcp;
        proxy_set_header    X-NginX-Proxy       true;
    }

    location / {
        proxy_pass          http://other;
        proxy_http_version  1.1;
        proxy_set_header    Host                $http_host;
        proxy_set_header    Upgrade             $http_upgrade;
        proxy_set_header    Connection          "Upgrade";
        proxy_set_header    X-Real-IP           $proxy_protocol_addr;
        proxy_set_header    X-Forwarded-For     $proxy_add_x_forwarded_for;
        proxy_set_header    X-Forwarded-Proto   tcp;
        proxy_set_header    X-NginX-Proxy       true;
    }
  }
