It is important to start by updating the system to ensure that all packages are in their latest version.

sudo apt update
sudo apt upgrade

        

Ubuntu includes Apache2 in its default repositories, making it easy to install using the command apt.

sudo apt install apache2

        

Once the installation is complete, the Apache2 server should start automatically. You can check its status with the following command:

sudo systemctl status apache2

        

You should see output similar to this, indicating that Apache2 is running:

● apache2.service - The Apache HTTP Server
     Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)
     Active: active (running) since Thu 2024-07-18 10:00:00 UTC; 1min 23s ago
   ...


        

If you have the UFW (Uncomplicated Firewall) enabled on your machine, you need to allow HTTP and HTTPS traffic. You can do it with the following commands:

sudo ufw allow 'Apache Full'

        

To check the status of the firewall and the rules that are applied, use:

sudo ufw status

        

To ensure that Apache2 is working correctly, open your web browser and navigate to your server's IP address. If you are running Apache on your local machine, you can use localhostand you can also use 127.0.0.1.

http://localhost

        

You should see the default Apache2 welcome page, confirming that the web server is installed correctly and working.

It is useful to know how to handle the Apache2 service. Here are some essential commands:

• Start Apache2:

  sudo systemctl start apache2
  
                  

• Stop Apache2:

  sudo systemctl stop apache2
  
                  

• Restart Apache2:

  sudo systemctl restart apache2
  
                  

• Reload Apache2 (applies configuration changes without disconnecting current connections):

  sudo systemctl reload apache2
  
                  

• Enable Apache2 to start automatically at system boot:

  sudo systemctl enable apache2
  
                  

• Disable Apache2 from starting automatically:

  sudo systemctl disable apache2
  
                  

The Apache2 configuration files are located in the /etc/apache2. Some important files and directories include:

• /etc/apache2/apache2.conf: Main configuration file.
• /etc/apache2/sites-available/: Configuration files for available sites.
• /etc/apache2/sites-enabled/: Symbolic links to files in sites-availablefor enabled sites.
• /etc/apache2/conf-available/y /etc/apache2/conf-enabled/: For global configuration modules.
• /var/www/html/: Default root directory for web documents.

To create a new website, you can copy the default configuration file and modify it according to your needs:

sudo cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/mysite.conf

        

Edit the file mysite.confwith a text editor:

sudo nano /etc/apache2/sites-available/mysite.conf

        

Inside this file, you can define the root directory of the website, the server name, etc. Here's a basic example:

<VirtualHost *:80>
    ServerAdmin webmaster@mysite.com
    ServerName mysite.com
    ServerAlias www.mysite.com
    DocumentRoot /var/www/mysite

    <Directory /var/www/mysite>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

        

Enable the new site and reload Apache2:

sudo a2ensite mysite.conf
sudo systemctl reload apache2

        

Congratulations! You now have Apache2 installed and configured on your Ubuntu server. Apache2 is a robust and flexible web server that can handle everything from small personal websites to large enterprise applications. Feel free to explore more about its configuration and additional modules to expand its functionality.
