The Apache HTTP Server Project is an effort to develop and maintain anopen-source HTTP server for modern operating systems including UNIX andWindows. The goal of this project is to provide a secure, efficient andextensible server that provides HTTP services in sync with the current HTTPstandards.
The Apache HTTP Server ('httpd') was launched in 1995 and it has been the most popular web server on the Internet sinceApril 1996. It has celebrated its 25th birthday as a project in February 2020.
Once the server's private key and certificate are ready, you can begin with SSL configuration of Apache web server. In many cases, this process is comprised of 2 steps – enabling modssl and creating virtual host for port 443/TCP. Enabling modssl is very easy, all you need to do is to open httpd.conf file and remove comment mark from line. How to install and secure apache web server on Debian 10 Linux operating system.

The Apache HTTP Server—known as Apache web server or simply Apache—is considered the standard for general-purpose HTTP activities and services. It offers a wide range of modules to deliver optimum flexibility in support of URL rewriting, proxy servers, and granular access management and control. Apache is a popular choice among web developers because it uses CGI, embedded interpreters, and FastCGI to support server-side scripting. This allows for the rapid and effective execution and implementation of highly dynamic coding.
There are plenty of well-known Apache alternatives—nginx, XAMPP, Caddy, and Microsoft IIS, among many others—but none of them offer the same breadth of usage provided by Apache. Apache is so widely used it has more than a 50% share in the commercial web server marketplace. It’s especially popular for use with Unix-like operating systems, although it supports most platforms. This includes Windows, OS X, OS/2, and others.

However, Apache’s flexibility and breadth of usage come at the expense of simplicity in many cases. The configuration structure is complex, and many of the advanced functionalities are difficult to use. This Apache server tutorial will explain the basics of Apache, providing instructions for Apache web server configuration in Linux, step by step. The aim is to help you not only set up Apache server, but also monitor it. My recommended tool for this purpose is SolarWinds® Server & Application Monitor for Apache.
A Simple Definition of Apache
Apache is a process-based, modular, open-source web server application designed to establish a new thread for each connection occurring simultaneously. Apache supports a range of functionalities, covering everything from authentication mechanisms to server-side programming languages. It also supports virtual hosting, allowing you to use one Apache web server to serve multiple websites. Most Apache capabilities are delivered as individual modules, allowing you to extend and enhance Apache’s core utilities.
How to Set Up Apache Server
You may find yourself becoming overwhelmed as you start to set up Apache server. As an open source, advanced application capable of a wide range of functions, Apache web server configuration and setup is fairly complex.
You can install and set up Apache server in two ways.
- Vendor-based installation. As it’s an open source web application, anyone can make an installer to suit their individual environment. Vendors like Red Hat, SUSE, and Debian have used this capability to customize Apache server configuration and file location by taking the base operating system and other installed programs into account.
- Source code installation. The alternative to using a vendor-based installer is to set up Apache server by building and installing directly from the source code. This approach enables you to set up Apache server in platform-independent manner available for all operating systems.
With both installation options, modules can be compiled in the form of a dynamic shared object, or DSO. A DSO is an object file capable of being shared and utilized by numerous applications. DSO modules are separate from the core Apache file. The DSO approach to compiling modules is popular because it makes adding, updating, and removing modules easy.

Apache Web Server Ssl Configuration Tool
This Apache server tutorial will now provide instructions for Apache web server configuration in Linux, step by step.
- Update your system repositories. This involves downloading the most recent version of a software by updating the Ubuntu repositories’ local package index. To do this, go to the terminal and enter the command “$ sudo apt update” into it.
- Install Apache by using the “apt” command. For this example, let’s use Apache2. Just input the following command— “$ sudo apt install apache2” —as sudo, which will install Apache2 and all necessary dependencies. At this stage, you may be asked whether you want to continue the installation process. Enter “Y” to indicate you would like to, and installation will begin.
- Verify Apache has been successfully installed. When the installation procedure has finished, check the version number to confirm Apache2 is now installed on your system. Enter “$ apache2 -version” to do this. The server version will appear, hopefully confirming Apache2 has been installed.
How to Set Up Apache Virtual Servers
When using virtual hosts, it’s important to undertake virtual server Apache configuration. Modifying configuration settings will ensure they reflect the domain specifics, which will allow Apache to respond to domain requests correctly and successfully. The process for completing virtual server Apache configuration is simple:
- First, input “$ sudo nano /etc/apache2/sites-available/example.com.conf” to open your virtual host configuration file.
- Replace “example.com” appropriately. Next, you’ll be able to modify the following:
ServerName example.com
ServerAdmin admin@example.com
ServerAlias www.example.com
DocumentRoot /var/www/example.com/public_htmlAgain, be sure to replace all example components with the appropriate information. When modified, the end result should resemble the following:
<VirtualHost *:80>
ServerName example.com
ServerAdmin admin@example.com
ServerAlias www.example.com
DocumentRoot /var/www/example.com/public_html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost> - If an error occurs, reference these instructions to ensure nothing has been mistyped or inputted incorrectly.
Best Apache Server Monitoring Tool
After setting up Apache web server, I highly recommend the use of a monitoring tool to help you test Apache server and monitor it effectively. There are several such tools on the market, but SolarWinds Server & Application Monitor (SAM) tops my list. This tool allows you to easily define specific performance metrics to facilitate proactive monitoring of Apache Cassandra, Apache Geronimo, and Apache Tomcat.
