Introduction
First, let’s understand what Nginx and CentOS are before delving deeper into their relationship. Nginx is an open-source web server that originated in Russia but has gained popularity globally. Nginx has gained traction due to its ability to handle high traffic loads while optimizing server resources efficiently. On the other hand, CentOS is a popular Linux distribution that is widely used to host web applications and services. CentOS is free and community-driven, making it ideal for web developers and system administrators.
When using Nginx server on CentOS, you can leverage the strengths of both systems to enhance your website’s performance and security.
What is Nginx Server?
Nginx is a lightweight, high-performance web server that can handle hundreds of thousands of concurrent connections efficiently. Nginx was created to solve the C10K problem, which refers to the challenge of efficiently handling an increasing number of connections to a web server. Nginx does this effectively by using an event-driven architecture and asynchronous processing. This allows Nginx to handle multiple requests simultaneously and handle high traffic loads without slowing down.
What is CentOS?
CentOS is a community-driven, free Linux distribution that is widely used for hosting web applications and services. CentOS is based on Red Hat Enterprise Linux (RHEL), which provides stability and security patches. CentOS is popular among web developers and system administrators due to its ease of use, stability, and security.
