What is Apache Web Server?
Apache is an open-source web server software that powers more than 40% of the websites on the internet. It is developed and maintained by the Apache Software Foundation, a non-profit organization that promotes open-source software projects. Apache is compatible with various operating systems (Windows, Linux, macOS, etc.) and supports a wide range of web technologies, including PHP, Perl, Python, and Ruby.
Apache is known for its stability, security, and scalability. It can handle large volumes of web traffic and requests without compromising performance or uptime. Apache also offers a rich set of features and modules that allow you to customize and extend its functionality. For example, you can use Apache to host multiple websites on the same server, set up SSL encryption, and configure access control.

During the installation process, you may be prompted to enter a password for the default Apache user (www-data). You can skip this step or set a password of your choice.
Step 3: Test Apache Installation
After installing Apache, you can test if it is running by opening a web browser and typing your Raspberry Pi’s IP address. You should see the default Apache welcome page. Alternatively, you can use the following command to check Apache status:
Command |
Description |
|---|---|
sudo systemctl status apache2 |
Displays the Apache service status |
How to Configure Apache Web Server on Raspberry Pi?
By default, Apache is configured to serve files from the /var/www/html directory. You can use a text editor (e.g., Nano) to modify the Apache configuration file (/etc/apache2/sites-available/000-default.conf) and change the document root, server name, and other settings.
Here are some useful Apache configurations for Raspberry Pi:
1️⃣ Enable PHP Support
If you want to run PHP scripts on your Apache web server, you need to install the PHP module and enable it. Use the following commands:
Command |
Description |
|---|---|
sudo apt-get install php libapache2-mod-php |
Installs the PHP module and its dependencies |
sudo a2enmod php |
Enables the PHP module |
2️⃣ Set Up SSL Encryption
If you want to secure your web server with SSL encryption, you can obtain a free SSL certificate from Let’s Encrypt and configure Apache to use it. Use the following guide:
3️⃣ Configure Access Control
If you want to restrict access to your web server or certain directories, you can use Apache’s access control features. Use the following guide:
