Knowing your Apache version is important for security updates, compatibility, and troubleshooting. By following these methods, you can easily determine your Apache version and stay informed about your web server's software.
What is Apache?
Before delving into the methods of checking Apache versions, it's important to have a basic understanding of what Apache is. Apache is a freely available, open-source web server software runs on numerous operating systems. It was initially released in 1995 and is maintained by the Apache Software Foundation.
Apache acts as an HTTP server, serving webpages and other files over the internet. Its main function is to efficiently handle requests from clients or users and deliver content reliably.
Renowned for its stability, security, and scalability, Apache is a popular selection for peoples, businesses, and other organizations seeking a dependable web server for hosting their websites. It also offers flexibility through a wide range of modules that allow web developers to customize the server's behavior according to their specific requirements. Apache follows a module-based system, enabling developers to add or remove components as needed.
To ensure the best performance and security, it is crucial to keep Apache up to date. Regular updates guarantee that you have the latest security patches and avoid potential issues encountered in previous versions.
Importance of Checking the Apache Version
Checking the Apache version on your server is important for several reasons.
By knowing the Apache version, you can stay informed about any security vulnerabilities that may affect your web server. Regularly updating Apache to the latest version ensures that you have the most up-to-date security patches, protecting your server and websites from potential threats.
Different versions of Apache may have varying features and configurations. Checking the version helps you ensure compatibility with other software and applications running on your server. It allows you to identify any potential compatibility issues and take appropriate measures to address them.
When encountering any issues or errors related to your web server, knowing the Apache version can be beneficial for troubleshooting. Certain problems may be specific to a particular version, and having this information can help you narrow down potential causes and find appropriate solutions more efficiently.
Overall, checking the Apache version is essential for maintaining security, ensuring compatibility, troubleshooting issues, and accessing appropriate documentation and support. It enables you to keep your web server up to date, secure, and optimized for efficient performance.
1. Checking the Apache Version from Terminal
There are multiple ways to check for Apache versions installed on your VPS, Cloud Dedicated Servers, and Dedicated Servers. Below are some of the most popular methods:
The output of the following command will display the current version of Apache installed on your system. Type the following command in your terminal and hit Enter.

Ensuring the security and reliability of your website relies on keeping Apache up to date. Two primary methods for checking the Apache version on your server have been discussed: through the command-line interface (CLI) or the Web Host Manager (WHM).
The CLI method involves utilizing a command-line interface to access your server and issue queries. This approach is suitable for experienced users who are familiar with server management.
Alternatively, the WHM method offers a user-friendly option for checking the Apache version through the Web Host Manager, even for users with limited experience in working with command-line interfaces. Simply access WHM, navigate to Server Status > Apache Status, and you will find the version of Apache installed on your server.
The cPanel method lets you check the Apache version on your server if you are a cPanel user and do not have access to the root level of the server at WHM.
Regardless of your chosen method, regularly checking your Apache version is crucial for safeguarding your website against security risks and reducing potential server issues. By keeping your version updated, you can ensure the optimal performance and protection of your website.
