Guide: Using NGINX as frontend webserver for MEAN
MEAN serves its pages on port 3000 per default, the easiest way to use port 80 (http) or 443 (https) is to utilize NGINX, this will also allow you later down the road to use the power of NGINX cache, or load balancing.
Ubuntu 16.04 server, and a MEAN stack installed. You can find a guide HERE, on how to install MEAN on Ubuntu 16.04
Step One – Installing NGINX
sudo apt install nginx
NGINX is now installed and you can find it on http://YOUR_SERVER_IP, however we need it to function as a proxy.
Step Two – Making NGINX work as a proxy
Open NGINX’s configuration file
sudo nano /etc/nginx/sites-enabled/default
Now find the location part of the configuration and insert the following line into the file as shown in the picture below
Note I’m using http://localhost:3000 since the NGINX application is on the same machine as the MEAN stack, change the IP to reflect your MEAN servers IP
Now just restart NGINX
sudo service nginx restart
Check that your server is redirecting by going to the address of your NGINX servers IP address.
You now have a working proxy server for your MEAN stack!
