Step-by-Step Guide to Installing Nginx on Ubuntu

Installing Nginx on Ubuntu is a common task for web administrators and developers. Below is a step-by-step guide that you can adapt for a blog post, tutorial, or instructional document.

### Introduction:
- Briefly introduce Nginx and its uses as a high-performance web server, reverse proxy, and HTTP cache.
- Outline the purpose of the guide: a straightforward installation of Nginx on an Ubuntu system.

### Pre-requisites:
- An Ubuntu server or desktop (mention specific versions if the guide is version-specific).
- Sudo or root access on the system.

### Step-by-Step Installation:

#### Step 1: Update Ubuntu Packages
- Start with updating the package lists to ensure you get the latest version of Nginx:

  sudo apt update


#### Step 2: Install Nginx
- Install Nginx using Ubuntu’s package manager:
 
  sudo apt install nginx
 

#### Step 3: Start and Manage the Nginx Service
1. **Start the Nginx Service:**
 
   sudo systemctl start nginx
 
2. **Enable Nginx to Start at Boot:**
 
   sudo systemctl enable nginx
 
3. **Check Nginx Service Status:**
 
   sudo systemctl status nginx
 

#### Step 4: Adjust Firewall Settings
- If UFW (Uncomplicated Firewall) is enabled, allow Nginx traffic:
 
  sudo ufw allow 'Nginx Full'
  sudo ufw status
 

#### Step 5: Verify Nginx Installation
- Confirm that Nginx is properly installed and accessible:
  - In a web browser, visit your server’s IP address or domain name: `http://your_server_ip/`
  - You should see the default Nginx welcome page.

#### Step 6: Configure Nginx (Optional)
- Basic configuration steps can include:
  1. **Navigate to Nginx's configuration directory:**
    
     cd /etc/nginx

  3. **Make necessary changes and save the file.**
  4. **Test the configuration for errors:**
   
     sudo nginx -t
    
  5. **Reload Nginx to apply changes:**
    
     sudo systemctl reload nginx
