VNet-Security-Setup-Azure

This repository contains the necessary instructions for setting up a secure network within Azure, including installing and configuring Nginx on an Ubuntu VM within the Azure Virtual Network (VNet). Below are the steps to install and configure Nginx on an Ubuntu VM hosted on Azure.

Steps to Install and Configure Nginx on Ubuntu (VM)

1. Access the VM Using Azure Bastion

To access the VM securely, use Azure Bastion. Follow these steps to connect to your VM:

• Go to the Azure portal.
• Navigate to Bastion under your created VNet (e.g., vnet-demo-network-Bastion).
• Click Connect.
• Choose SSH as the authentication type.
• Use your SSH private key (e.g., .pem file) to authenticate.
• Enter the username (azureuser) and select the private key you downloaded when you created the VM.
• Click Connect. This will open a terminal session on the VM.

2. Update the Ubuntu System

Once connected to your VM, it's important to update the package list and upgrade existing packages:

sudo su -
sudo apt update
sudo apt upgrade -y

3. Install Nginx

Now, install Nginx on the Ubuntu VM:

sudo apt install nginx -y

4. Start and Enable Nginx

After installation, start the Nginx service and enable it to start on boot:

sudo systemctl start nginx
sudo systemctl enable nginx

5. Create and Configure the HTML File

Create a simple static HTML page that will be served by Nginx. You can edit the default HTML file or create a new one:

sudo vim /var/www/html/index.html

Add your HTML content to this file. You can find the HTML code used in this project in the repository. If you'd like to see the exact HTML content I used, you can access it directly in the index.html file of this repository Save and exit the editor by pressing Esc then typing :wq and pressing Enter.

6. Restart Nginx to Apply Changes

To ensure Nginx picks up the changes to the HTML file, restart the Nginx service:

sudo systemctl restart nginx

7. Verify Nginx Installation

To verify that Nginx is serving the page correctly, run the following command from the Bastion terminal:

curl localhost:80
