In order to run two Node apps on a single Droplet, you’ll need to configure a reverse proxy to direct requests to the correct applications. Nginx is a popular choice for doing this. Each app will need to be configured to listen on a separate port locally while Nginx will listen publicly with a “server block” for each app. A quick minimal example of the Nginx configuration would look like:
server {
listen 80;
server_name subdomain1.example.com;
location / {
proxy_pass http://localhost:PORT_ONE;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
server {
listen 80;
server_name subdomain2.example.com;
location / {
proxy_pass http://localhost:PORT_TWO;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
Depending on the details of your applications, there may be additional configuration needed. Check out these tutorials for more information. The first covers Nginx server blocks; the second is specifically on using Nginx as a reverse proxy for Node apps:
@asb i did the same config but the sub domain not working. but the ip:port still running right
did it need to setup DNS ??
