Welcome, webmasters and hosting technicians! If you want to keep your website optimized and secure, you should know how to check your server Apache version. Apache, as you may know, is the most popular web server software worldwide. It powers about 40% of websites on the internet, according to Netcraft’s survey.
As a website owner or developer, you must keep your server software up-to-date to maintain compatibility with the latest web technologies, plugins, and security patches. But how do you check your Apache version? What are the benefits and drawbacks of upgrading or downgrading? How can you troubleshoot version conflicts and errors? In this comprehensive guide, we’ll answer all these questions and more.
1. What Is Apache Server?
Apache HTTP Server, commonly referred to as Apache, is an open-source, cross-platform software that runs on Unix, Linux, Windows, and other operating systems. It was first released in 1995 and has since evolved to become the most widely used web server on the planet. Apache supports a variety of programming languages, such as PHP, Perl, Python, and Ruby, as well as SSL/TLS encryption and virtual hosting.
2. Why Check Server Apache Version?
Knowing your Apache version is useful for several reasons:
- Compatibility: Each Apache version may have different features, bugs, and requirements that affect how your website behaves, interacts with databases, or loads content. By checking your current version, you can ensure that your website is optimized and compatible with your software stack.
- Security: Older Apache versions are more vulnerable to security breaches, attacks, and exploits. Hackers can exploit known vulnerabilities to gain access to your server, steal sensitive data, or install malware. By checking and updating your Apache version, you can reduce the risk of security breaches.
- Performance: Apache versions may vary in terms of speed, memory usage, and resource allocation. By checking and comparing different versions, you can optimize your website performance and ensure that your server can handle high traffic and load demands.
3. How to Check Your Server Apache Version?
There are several ways to check your Apache version, depending on your operating system, hosting provider, or access level:
Method |
Description |
|---|---|
Apache HTTP Server Version |
If you have access to your server command line interface, you can type the following command to get the Apache version: |
httpd -v |
This will output the Apache version, like “Server version: Apache/2.4.6 (CentOS)” |
cPanel Apache Version |
If you have a cPanel hosting account, you can find the Apache version in the “Server Information” section: |
cPanel > Home > Server Information |
Look for the “Apache version” field, which should display the current version number. |
phpinfo Apache Version |
If you have PHP installed on your server, you can create a PHP script that will display the Apache version: |
<?php phpinfo(INFO_MODULES); ?> |
This will show a comprehensive PHP information page, including the Apache version in the “Loaded Modules” section. |
4. What Are the Latest Apache Versions?
As of September 2021, the latest stable release of Apache is version 2.4.48, which was released on September 14, 2021. This version includes several bug fixes and security enhancements, such as mitigations against HTTP/2 flood attacks and NULL pointer dereference in the mod_proxy module.
Before version 2.4, Apache was developed under the 2.2 branch, which is now considered outdated and no longer supported. If you’re still using Apache 2.2 or earlier, you should upgrade to version 2.4 or later to benefit from the latest features and security measures.
