Reverse Proxy Server for Ubuntu 23.04
What You Will Need
Before you start, you will need the following:
- An Ubuntu Server (Version 20.04 LTS or newer). If you don’t have it, download it from Ubuntu’s official website.
- Nginx installed on your server. If you don’t have it, don’t worry, we will cover this step in the tutorial.
- Basic knowledge of Linux commands and text editors such as nano or vim.
Step 1: Update Your Ubuntu Server
First, ensure your Ubuntu server is up to date. Open the terminal and execute the following commands:
sudo apt update
sudo apt upgrade
These commands will update the package lists and upgrade all the installed packages to their latest versions.
Step 2: Install Nginx
Next, install Nginx by using the command:
sudo apt install nginx
After installation, start the Nginx service with:
sudo systemctl start nginx
You can also enable Nginx to start on boot with:
sudo systemctl enable nginx
Step 3: Configure Nginx as a Reverse Proxy
To configure Nginx as a reverse proxy, you need to edit the Nginx configuration file. Use the text editor of your choice (we’re using nano here) to open the file:
sudo nano /etc/nginx/sites-available/default
Delete everything in this file and replace it with the following:
server {
listen 80;
location / {
proxy_pass http://your_backend_server_ip;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
Replace your_backend_server_ip with the IP address of your backend server.
Save and exit the text editor (In nano, use CTRL+X, then press Y and enter to save and exit).
Next, check the syntax of your configuration file with:
sudo nginx -t
If the syntax is okay, reload Nginx to apply the changes:
sudo systemctl reload nginx
Congratulations! You have set up Nginx as a reverse proxy server on your Ubuntu Server.
Step 4: Test the Setup
You can test if the reverse proxy is working by visiting your server’s public IP address in a web browser. If it’s set up correctly, you should see the default webpage of your backend server.
Conclusion on Setting Up a Reverse Proxy
In this tutorial, we walked through the steps needed to set up a reverse proxy server using Nginx on an Ubuntu Server. If you followed all the steps carefully, you should have a working reverse proxy server.
