Proxy Server

Set up a proxy

In this step we will setup an apache proxy server: Our server is an ubuntu server (18.04.2).

Install and setup apache

We can install the apache server with the following commands:

sudo apt update
sudo apt install apache2

Now we have to set it up by editing the 000-default.conf. You can use vim or any other text-editor:

vim /etc/apache2/sites-available/000-default.conf

Edit the file to have these lines:

<VirtualHost *:80>
        ServerName <yourdomain.example.com>
        ServerAdmin webmaster@localhost
        ProxyPass "/" "http://localhost:4000/"
        ProxyPassReverse "/" "http://localhost:4000"
</VirtualHost>

Enable the proxy and proxy_http modules with this command:

a2enmod proxy proxy_http

Restart the apache server:

systemctl restart apache2

Enable HTTPS

We use certbot to set up HTTPS. The easiest and most up-to-date instructions can be found on https://certbot.eff.org/instructions. Setting this up should take about 5 minutes.
