Step-by-Step Guide to Installing Nginx on RHEL 8

 Installing Nginx on Red Hat Enterprise Linux (RHEL) 8 is a critical task for setting up a robust and efficient web server. Below is a step-by-step guide for installing Nginx on RHEL 8, which can be adapted for a blog post, tutorial, or documentation.

### Introduction:
- Introduce Nginx as a popular, high-performance web server and reverse proxy.
- Explain the objective of the guide: to install Nginx on a RHEL 8 system.

### Pre-requisites:
- A RHEL 8 server.
- Sudo or root privileges.

### Step-by-Step Installation:

#### Step 1: Register Your RHEL System
- Ensure your system is registered with Red Hat Subscription Management and is subscribed to the required repositories.
 
  sudo subscription-manager repos --enable=rhel-8-for-x86_64-appstream-rpms
 

#### Step 2: Install Nginx
1. **Install Nginx:**
   - Nginx is available in the AppStream repository in RHEL 8:
    
     sudo dnf install nginx
     

#### Step 3: Start and Enable Nginx Service
1. **Start the Nginx service:**
 
   sudo systemctl start nginx
   
2. **Enable Nginx to start automatically at system boot:**
   
   sudo systemctl enable nginx
   

#### Step 4: Verify the Nginx Installation
- Confirm that Nginx is running:
 
  sudo systemctl status nginx
 
- Access the default Nginx landing page by visiting `http://your_server_ip/` in a web browser.

#### Step 5: Configure Firewall Settings
- If your system uses firewalld, allow HTTP and HTTPS traffic:
 
  sudo firewall-cmd --permanent --zone=public --add-service=http
  sudo firewall-cmd --permanent --zone=public --add-service=https
  sudo firewall-cmd --reload
 

#### Step 6: Basic Configuration of Nginx
- Discuss the basic structure of Nginx's configuration files located in `/etc/nginx/`.
- Guide on editing the default server block configuration:
 
  sudo vi /etc/nginx/nginx.conf
 
- Mention the importance of testing the configuration and restarting Nginx after changes:
 
  sudo nginx -t
  sudo systemctl restart nginx
 

### Post-Installation Tips:
- Suggest best practices for managing Nginx, like setting up virtual hosts (server blocks).
- Briefly mention securing Nginx with SSL/TLS.

### Conclusion:
- Recap the importance of using Nginx for web serving and reverse proxying.
- Encourage readers to explore advanced Nginx features and configurations.
