setup multiple virtual hosts on same port in nginx

When you run multiple websites, it might be a good idea to run them on same port to save resources and server costs. If you use virtual hosts, then here’s how to setup multiple virtual hosts using same port in NGINX.

 

How to Setup Multiple Virtual Hosts using Same Port in NGINX

Here are the steps to setup multiple virtual hosts using same port in NGINX. Before you proceed make sure you have enabled virtual hosts in NGINX. Here are the steps to do it.

 

Let’s say you want to host 2 websites www.example.com and api.example.com on port 80.

 

1. Create Virtual host files

Create 2 separate virtual host files – one for each website


$ sudo vim /etc/nginx/sites-available/www.example.com
$ sudo vim /etc/nginx/sites-available/api.example.com

 

2. Add Virtual Host Configuration

Add the following lines of code in the 2 files

#www.example.com


server {
 listen 80
 server_name www.example.com
 root /var/www/www.example.com/html/example/app; #also add a root dir here
 location / {
  proxy_set_header Host $host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_pass http://127.0.0.1:3836;
 }
}

 

 

#api.example.com


server {
 listen 80
 server_name api.example.com
 root /var/www/api.example.com/html/example/app; #also add a root dir here
 location / {
  proxy_set_header Host $host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_pass http://127.0.0.1:3836;
 }
}

 

The key is to differentiate the 2 configs with server_name directive. Also, use the appropriate root folder location for each website.

 

 

3. Enable the domains

Next, enable the 2 domains


$ sudo ln -s /etc/nginx/sites-available/www.example.com /etc/nginx/sites-enabled/www.example.com
$ sudo ln -s /etc/nginx/sites-available/api.example.com /etc/nginx/sites-enabled/api.example.com

 

 

4. Reload NGINX web server

Reload NGINX server to apply changes.

$ sudo service nginx reload

 

That’s it! NGINX will serve both your websites from the same port.
