Tasks​

  1. Configure Apache to serve a basic website that shows "Hello RHCSA!".

  2. Use this basic HTML file:

    <!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <title>Hello RHCSA!</title>
    </head>
    <body>
        <h1>Hello RHCSA!</h1>
        <p>Welcome to my Apache server.</p>
    </body>
    </html>

Solution​

1. Install Apache Web Server​

On Red Hat-based systems like CentOS or RHEL, you can install Apache using yum:

sudo yum install httpd

2. Start and Enable Apache​

Start the Apache service and enable it to start automatically on boot:

sudo systemctl start httpd
sudo systemctl enable httpd

3. Create a Basic HTML File​

Create a simple HTML file that contains the desired content. For this task, create a file named index.html with the following content:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Hello RHCSA!</title>
</head>
<body>
    <h1>Hello RHCSA!</h1>
    <p>Welcome to my Apache server.</p>
</body>
</html>

4. Move to Apache's Document Root​

The default document root for Apache on CentOS/RHEL is /var/www/html/. Copy or move the index.html file to this directory:

sudo mv index.html /var/www/html/

5. Set Permissions (optional)​

Ensure that Apache has permissions to read the files in /var/www/html/. Usually, Apache runs as the apache or httpd user and group. Set the correct permissions if needed:

sudo chown -R apache:apache /var/www/html/
sudo chmod -R 755 /var/www/html/

6. Configure Firewall (optional)​

If the firewall is enabled, allow HTTP traffic (port 80):

sudo firewall-cmd --zone=public --add-service=http --permanent
sudo firewall-cmd --reload

7. Access the Website​

Open a web browser and enter your server's IP address or hostname in the address bar:

http://your_server_ip_address/

You should see the webpage displaying "Hello RHCSA!".
