FAQs )(Frequently Asked Questions)
What is Apache Web Server?
Apache Web Server is a free, open-source web server software that is widely used to serve web pages. It’s known for its flexibility, reliability, and extensibility.
How do I install Apache Web Server?
Apache can be installed on various operating systems. On Linux, it’s often installed using package managers like
yum. On Windows, you can download the installer from the Apache website. Each platform has its specific installation steps.
Can Apache run on both Windows and Linux?
Yes, Apache Web Server can be run on Windows, Linux, and MacOS, making it a versatile choice for different environments.

This depends on your operating system. On Linux, you typically use commands like
sudo systemctl start httpd or
sudo systemctl stop httpd. On Windows, you can start or stop Apache from the Services management console.
How do I configure virtual hosts in Apache?
Virtual hosts allow you to host multiple websites on a single server. You configure them by editing the
vhosts.conf file in your Apache configuration directory.
What are Apache modules and how do I use them?
Apache modules add extra features to the server. They can be enabled or disabled in the Apache configuration files. Common modules include mod_ssl for HTTPS, mod_rewrite for URL rewriting, and mod_security for security enhancements.
How do I secure my Apache Web Server?
