How to Change Apache's Default HTTP Port on Linux (Debian/Ubuntu)

Verifying Apache Status and Default Port

• 🎯 Verify Apache 2 status using sudo systemctl status apache2 to ensure it's active and running.
• 💡 Test the default HTTP port (80) by navigating to http://localhost or http://localhost:80 in your browser to confirm Apache is accessible.

Editing Apache Configuration File

• 🛠️ Access the Apache configuration file by using the command sudo nano /etc/apache2/ports.conf.
• 📌 Locate the Listen 80 directive within the ports.conf file.

Changing and Restarting Apache Service

• ⚡ Modify the Listen directive from 80 to your desired port, for example, 7000.
• 💾 Save the changes by pressing Ctrl+O, Enter, and exit the editor with Ctrl+X.
• 🔄 Restart the Apache service to apply the changes with sudo systemctl restart apache2.

Verifying the New Port Configuration

• ✅ Confirm that Apache is running again using sudo systemctl status apache2.
• 🚀 Test the new port by accessing http://localhost:7000 in your browser to ensure Apache is now listening on the custom port.
