Install Apache Webserver:

#apache #linux #aws #devops

To install the Apache web server on Ubuntu using the terminal, follow these steps:

Open Terminal:
You can press Ctrl + Alt + T to open a terminal window.
Update Package List:
Run the following command to update the package list before installing Apache:

   sudo apt update

Install Apache: Use the following command to install Apache:

   sudo apt install apache2

Start Apache Service: Once Apache is installed, start the Apache service:

   sudo systemctl start apache2

Enable Apache to Start at Boot: To ensure that Apache starts automatically when your system boots up, enable the Apache service:

   sudo systemctl enable apache2

Check Apache Status: You can verify whether Apache is running by checking its status:

   sudo systemctl status apache2

This command will display information about the Apache service's current status.

Adjust Firewall (if needed): If you have a firewall enabled (like ufw), you might need to allow HTTP traffic. You can use the following command:

   sudo ufw allow 'Apache'

Replace 'Apache' with 'WWW Full' if you're using the default UFW application profiles.

Test Apache Installation: Open a web browser and enter your server's IP address or domain name. If Apache is installed correctly, you should see the default Apache2 Ubuntu Default Page.

That's it! You've successfully installed Apache on your Ubuntu system. You can now proceed to install other components of your LAMP stack, such as MySQL and PHP, to complete your web server setup.
