Reverse Proxy Nginx Ubuntu 20.04

Requirement

• Web Server Running (Apache2 on IP 10.10.10.1:80)
• Reverse Proxy (Nginx on IP 10.10.10.2)

Assumption

It is assumed that a web server is already running. In this example, the web server runs on IP 10.10.10.1:80.
The reverse proxy server will be running on a different VM or server with IP 10.10.10.2.

Installation

Install Nginx

apt install nginx

Unlink default config nginx

unlink /etc/nginx/sites-enabled/default

Create file reverse-proxy.conf in /etc/nginx/sites-availible

touch /etc/nginx/sites-available/reverse-proxy.conf

Add the following configuration to the file:

server {
    listen 80;
   # listen 443 ssl;
    server_name www.domain.com;
    access_log /var/log/nginx/reverse-proxy-access.log;
    error_log /var/log/nginx/reverse-proxy-error.log;
   # ssl on;
       # include snippets/ssl-defaults.conf;
       # include snippets/proxy-defaults.conf;

    location / {
        #Set header Proxynya
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Accept-Encoding "";

         #Tujuan permintan diteruskan
        proxy_pass http://10.10.10.1/;
    }
}

Then, create a symbolic link for reverse-proxy.conf in sites-enabled:

ln /etc/nginx/sites-available/reverse-proxy.conf /etc/nginx/sites-enabled/reverse-proxy.conf

Check if the configuration is correct:

nginx -t

Restart Nginx and enable it to start automatically on boot:

systemctl restart nginx

systemctl enable nginx

Test the setup by accessing the reverse proxy server's IP.
If the configuration is correct, you should see the web server from Server 1.

Happy trying!
