Scroll down to the `Directory` section and adjust the settings according to your preferences, such as enabling `.htaccess` files or setting the `AllowOverride` directive.
To host your website files, navigate to the `/var/www/html/` directory using `cd /var/www/html/`. This is the default location where Apache looks for web pages. Create a new file named `index.html` using `sudo nano index.html` and add your HTML content. Save the file and exit the editor.
If you want to host multiple websites on your Raspberry Pi, you can create virtual hosts. Start by creating a new directory for your website within the `/var/www/` directory, such as `/var/www/mywebsite/`. Then, create a new configuration file in `/etc/apache2/sites-available/` using a command like `sudo nano /etc/apache2/sites-available/mywebsite.conf`. Configure the virtual host by specifying the `ServerName`, `DocumentRoot`, and other relevant directives.
Enable the virtual host using `sudo a2ensite mywebsite.conf` and disable the default site with `sudo a2dissite 000-default.conf`. Finally, restart the Apache service using `sudo service apache2 restart` for the changes to take effect. Your Raspberry Pi web server is now set up and ready to host your websites.
Create a Network-Attached Storage (NAS) Device
Creating a Network-Attached Storage (NAS) device with your Raspberry Pi is an excellent way to centralize your file storage and backup needs.
