What is a Web Server?
A web server is a server that stores and delivers web pages and other content to users’ computers. It is the backbone of the internet, allowing users to access information and interact with websites. Web servers use HTTP (Hypertext Transfer Protocol) to communicate with clients, such as web browsers, and deliver the requested content in the form of HTML, images, videos, and other multimedia.
Why Choose Debian 9 for Your Web Server?

It is an open-source operating system that is free to use and has a large community of developers and users. Debian 9 (code-named “Stretch”) is the latest stable release of Debian and comes with many updated packages and features.

Web Server Debian 9 Install
Step 1: Install the Apache Web Server
The Apache web server is one of the most popular web servers in the world. It is fast, reliable, and easy to configure. To install Apache on Debian 9, simply run the following command:
sudo apt-get install apache2
Step 2: Configure Apache
After installing Apache, you need to configure it to work with your system. The main configuration file for Apache is located at /etc/apache2/apache2.conf. You can edit this file using your favorite text editor, such as nano or vim. Here are some important settings that you should consider:
- ServerName: Sets the fully qualified domain name of the server
- DocumentRoot: Sets the directory where the web pages are stored
- ErrorLog: Sets the file where errors are logged
- DirectoryIndex: Sets the default file to be served when a directory is requested
Step 3: Test Your Installation
After configuring Apache, you should check if it is working properly. To do this, open your web browser and go to http://localhost/. You should see the Apache default page that says “It works!” If you see this page, congratulations! You have successfully installed and configured Apache.
Step 4: Install PHP and MySQL
If you want to create dynamic web pages, you need to install PHP and MySQL. PHP is a server-side scripting language that is used to create web applications, while MySQL is a relational database management system that is used to store data. To install PHP and MySQL on Debian 9, run the following command:
sudo apt-get install php7.0 php7.0-mysql mysql-server
Step 5: Configure PHP and MySQL
After installing PHP and MySQL, you need to configure them to work with Apache. The main configuration file for PHP is located at /etc/php/7.0/apache2/php.ini, while the main configuration file for MySQL is located at /etc/mysql/mysql.conf.d/mysqld.cnf. Here are some important settings that you should consider:
- display_errors: Sets whether to display errors in the browser
- max_execution_time: Sets the maximum time that a script can run
- post_max_size: Sets the maximum size of POST data
- upload_max_filesize: Sets the maximum size of uploaded files
- bind-address: Sets the IP address that MySQL listens on
- max_connections: Sets the maximum number of concurrent connections to MySQL
Step 6: Test Your Installation
After configuring PHP and MySQL, you should check if they are working properly. To do this, create a new PHP file in your Apache web root directory and add the following code:
<?php phpinfo(); ?>
Save the file as info.php and open your web browser to http://localhost/info.php. You should see a page that displays the PHP version and configuration information. If you see this page, congratulations! You have successfully installed and configured PHP and MySQL.
