O n the left menu bar search for “ Server status ” section under that select “ Apache status “. Clicking on it will display the server version in the second line.
Apache HTTP server is the world’s most used web server. Most of the web hosting providers use Apache as their web server. This is the reason 67% of web servers in the world use Apache as their web server. It is actively maintained by open community developers around the world and the last release is 2.4.13. The Apache HTTP Server Project is an effort to develop and maintain an open-source HTTP server for modern operating systems including UNIX and Windows. The goal of this project is to provide a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards.
Configuring the source tree
The next step is to configure the Apache source tree for your particular platform and personal requirements. This is done using the script configure included in the root directory of the distribution. (Developers downloading an unreleased version of the Apache source tree will need to have autoconf and libtool installed and will need to run buildconf before proceeding with the next steps. This is not necessary for official releases.)
To configure the source tree using all the default options, simply type ./configure. To change the default options, configure accepts a variety of variables and command line options.
The most important option is the location --prefix where Apache is to be installed later, because Apache has to be configured for this location to work correctly. More fine-tuned control of the location of files is possible with additional configure options.
Also at this point, you can specify which features you want included in Apache by enabling and disabling modules. Apache comes with a wide range of modules included by default. They will be compiled as shared objects (DSOs) which can be loaded or unloaded at runtime. You can also choose to compile modules statically by using the option --enable-module=static.
Additional modules are enabled using the --enable-module option, where module is the name of the module with the mod_ string removed and with any underscore converted to a dash. Similarly, you can disable modules with the --disable-module option. Be careful when using these options, since configure cannot warn you if the module you specify does not exist; it will simply ignore the option.
In addition, it is sometimes necessary to provide the configure script with extra information about the location of your compiler, libraries, or header files. This is done by passing either environment variables or command line options to configure. For more information, see the configure manual page. Or invoke configure using the --help option.
For a short impression of what possibilities you have, here is a typical example which compiles Apache for the installation tree /sw/pkg/apache with a particular compiler and flags plus the two additional modules mod_ldap and mod_lua:
$ CC='pgcc' CFLAGS='-O2'
./configure --prefix=/sw/pkg/apache
--enable-ldap=shared
--enable-lua=shared
When configure is run it will take several minutes to test for the availability of features on your system and build Makefiles which will later be used to compile the server.

Details on all the different configure options are available on the configure manual page.
Apache is a popular open-source, cross-platform web server that is, by the numbers, the most popular web server in existence. It’s actively maintained by the Apache Software Foundation.
Some high-profile companies using Apache include Cisco, IBM, Salesforce, General Electric, Adobe, VMware, Xerox, LinkedIn, Facebook, Hewlett-Packard, AT&T, Siemens, eBay, and many more (source).
In addition to its popularity, it’s also one of the oldest web servers, with its first release all the way back in 1995. Many cPanel hosts utilize Apache today. Like other web servers, Apache powers the behind-the-scenes aspects of serving your website’s files to visitors.
Because Apache doesn’t perform as well in some benchmarks, especially for static websites or websites with high traffic, Kinsta uses the NGINX web server instead of Apache. Though NGINX hasn’t been around for as long as Apache, it’s quickly grown in popularity and market share since its launch in 2004.
How Does Apache Work? Web Server Basics Explained
While there’s a lot of complexity underpinning how a web server functions, the basic job of all web servers is to accept requests from clients (e.g. a visitor’s web browser) and then send the response to that request (e.g. the components of the page that a visitor wants to see).
The Apache web server has modules which add more functions to its software, such as MPM (for handling multi-processing modes) or mod_ssl for enabling SSL v3 and TLS support (suggested reading: TLS vs SSL). Some common features seen in Apache include:
- IPv6
- FTP
- Perl, Lua, and PHP
- Bandwidth throttling
- WebDAV
- Load balancing
- URL rewriting
- Session tracking
- Geolocation based on IP address
While a web server is an essential part of any website, it’s important to note that casual WordPress users are unlikely to interact with their web server directly most of the time.
Apache vs Nginx Usage Stats
When you look at every single website on the Internet, Apache is the most popular web server. It powers 47% of the websites with a known web server, according to W3Techs.
However, Apache’s usage greatly drops when you start looking at the web’s most highly trafficked sites. Apache only powers:
- 27.1% of the 100,000 most popular sites
- 21.5% of the 10,000 most popular sites
- 16.2% of the 1,000 most popular sites
This drop-off likely stems, at least in part, from Apache’s lower benchmarks for high traffic websites.
Conversely, NGINX, the web server that Kinsta uses, is used by a majority of high-traffic sites, powering:
- 56.1% of the 100,000 most popular sites
- 63.2% of the 10,000 most popular sites
- 57% of the 1,000 most popular sites
If you check the Google Search trends since 2004, you can see this trend play out where Apache’s popularity (as a search term) is decreasing while NGINX’s is creeping up.
How To Check Which Web Server You’re Using
If you want to see whether you’re using Apache or NGINX, you can often (but not always) look at your site’s HTTP header.
What Version Of Apache
To view your site’s HTTP header, you can:
- Use the Network tab of Chrome Developer Tools
- Use a tool like Pingdom or GTmetrix
Apache HTTP header
This method may not work if you’re using a service like Cloudflare, though.
