Understanding the web server and how it works is essential. A web server in Linux is software that displays web content, such as web pages, images, and videos, to the clients, usually browsers, across the internet or a private network. Web servers on Linux systems are one of the primary tools for running websites and web applications.

The web server, in turn, monitors incoming requests by various clients over HTTP or HTTPS, processes them, and finally serves the respective resources.

Most Popular Web Server in Linux
Here’s a list of some of the most common web servers currently running on Linux:

1. Apache HTTP Server
Apache HTTP Server is one of the most widely-used open-source web servers, flexible, secure, and used in various segments of technology.

2. Nginx
Nginx is another high-performance, lightweight web server in Linux, commonly used as a reverse proxy or load balancer for seamless and better efficiency in handling concurrent connections.

3. LiteSpeed
The LiteSpeed web server in Linux proves to be a high-speed, scalable web server that is highly oriented to performance and security.

4. Caddy
Another popular web server in Linux is Caddy. It’s a new, user-friendly web server that automatically manages SSL certificates.

Core Features of the Web Servers in Linux
HTTP/HTTPS protocols: These basic protocols are used to offer content over the internet using the features of the web servers.
Virtual hosting: With the best web servers in Linux, one can host more than one domain on a single server.
Security: Using SSL/TSL, web servers provide encryption for secure data transfer.
Configuration Files: Linux-web servers are highly configurable via text files. This can be done through httpd.conf with Apache or through nginx.conf with Nginx.
Modules/Extensions: Using web servers, users get a mechanism by which the capability of a server to serve different kinds of dynamic content increases. Many software applications use PHP or Python for the same reason.
