Installing and configuring Apache webserver

1. Install Apache webserver. See Prerequisites for complete installation instructions.

2. Verify that Apache is installed correctly. Enter the following at the command line:

    sudo systemctl start httpd
   

   You should see the apache server active on default port 80: Active: active (running) since Mon 2020-06-01 22:22:43 GMT; 2s ago

3. Enable the Apache server to start up automatically at system boot time.

    sudo systemctl enable httpd
   

4. Update the host firewall to allow requests to the apache web server.

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

5. Update Apache to listen on port 8080. Add a new line to httpd.conf below the default Listen 80 entry.

    sudo nano /etc/httpd/conf/httpd.conf 
   

    # Change this to Listen on specific IP addresses as shown below to 
    # prevent Apache from glomming onto all bound IP addresses.
    #
    #Listen 12.34.56.78:80
    Listen 80
    Listen 8080
   

6. Open a browser and check that Apache is available at http://127.0.0.1:8080. You should see a test page. This means that Apache is running and succesfully configured to listen on port 8080.
