Nginx (“engine x”) is open source web server software technology that also does reverse proxying, load balancing, and caching and is popular because of its high-performance lightweight architecture.

What is Nginx server?

Nginx server is a free, open-source web server. It runs on 64bit Linux/Unix operating systems and is widely used for high-performance websites due to its lightweight architecture in comparison with Apache servers. In this article, we will provide you with basic information about Nginx, configuration examples, and which modules are required for certain features of your website. We will also answer frequently asked questions about the Nginx servers and provide practical solutions for common problems encountered on the web.


More about the NGINX server?

Nginx is a high-performance web server with a lightweight architecture. It runs on 64bit Linux/Unix operating systems and is widely used for high-traffic websites because it can handle more concurrent connections than Apache servers. Nginx has been shown to outperform Apache in benchmarks, especially when serving static files.

The Nginx configuration file is located at /etc/Nginx/Nginx.conf and contains directives that control the operation of the server. Nginx modules are located in the /usr/lib64/Nginx/modules directory. The most commonly used modules are:

  • core – basic Nginx functionality
  • SSL – provides SSL support
  • proxy – enables reverse proxy support
  • geo – enables geolocation support
  • event – enables event-driven programming model

There are many other modules available, and the list changes frequently. You can find a current list of Nginx modules at the Nginx wiki.

How does the Nginx server work?

Nginx is a powerful web server software that can handle large volumes of traffic very well. It’s also open source and free to use. In this article, we will take a look at how Nginx works and some of its benefits.

Nginx uses a master-worker model in which one master process delegates work to worker processes. Nginx is generally used as a web server software that can handle large volumes of traffic very well, but it’s also capable of acting as a reverse proxy and load balancer.

One of Nginx’s key benefits is its ability to handle a high number of concurrent connections. It can do this by using a variety of techniques such as keeping connections open for longer periods of time, or alternatively, by using event-driven programming. In this latter approach, new requests are pulled in by the worker processes when needed.

Nginx is also capable of serving static content very quickly and efficiently since it can deliver these directly from RAM if they have been cached before or served out of a storage device such as an SSD instead. Nginx has its own caching system called FastCGI which is also used by PHP.

Nginx works on most Unix-like operating systems and it has been shown to perform well even under very high loads, making it a favorite web server for many hosting companies and large sites such as Facebook and Wikipedia that receive millions of hits per day. You can see how Nginx performs with regards to other web servers on the benchmarking site, WebPageTest.org.

In conclusion, Nginx is a powerful and versatile web server software that has many benefits over other options such as Apache. It’s open-source and free to use, it can handle large volumes of traffic very well, and it’s also capable of serving static content quickly and efficiently. If you’re looking for a web server that’s reliable and can handle high loads, then Nginx is a great choice.

Benefits of using the NGINX server?

NGINX is an open-source reverse proxy server that has the capabilities to solve your hosting problems. It is known for its speed, reliability, and rich set of features.

Nowadays it is preferred by the majority of web hosts because it allows you to handle more traffic on a single machine while reducing resource utilization. The reason why NGINXis used more often than Apache is that it allows better memory utilization and faster web page load speeds.

NGINX, pronounced as Engine X, was released by Igor Sysoev in 2002. It has seen a tremendous rise since then. There are many benefits of using the NGINX server over other servers which are listed below:

It is faster than Apache and LiteSpeed. NGINX was designed in such a way that it sends the response back to the client only after fully loading all components of that file in memory, whereas in the case of Apache, each module loads into memory separately when required. This results in better utilization of resources making your website load faster. It is more resource-efficient. It uses a smaller amount of RAM and does not require frequent restarts.

It is scalable. You can add or remove NGINX web servers according to your website traffic and their performance will not be affected. NGINX Plus supports popular web servers with an API gateway for incoming traffic and commercial support.

It supports load balancing and reverses proxy functionality right out of the box without installing any additional software. It comes with a wide range of extensionless system resources when compared to other servers.

It supports HTTP, HTTPS, SMTP, POP3, and IMAP protocols for communication between web servers and clients. It requires external HTTP server authentication and an HTTP load balancer with an asynchronous architecture.

It can be easily integrated with various third-party software like WordPress which lets you run your blog more efficiently on the NGINX server.

It does not have any licensing issues. It is licensed under the BSD license which means it is free of cost to use for both commercial and noncommercial purposes.

It can be used as an HTTP or mail proxy, a reverse proxy, or a FastCGI webserver.

Bottom Line

NGINX server is a per-HTTP Web server that handles incoming requests for a website. NGINX is the most popular high-performance HTTP server in use today, with an upsurge of its share since 2015.

NGINX stands for Engine X. It was initially created by Igor Sysoev and is now actively developed by a community of about 300 programmers. NGINX’s main purpose is to be a Web server, but it can also act as a reverse proxy and HTTP cache, making it very flexible so that its use goes beyond merely serving Web pages.

Nowadays NGINX is used by more than half of the world’s top 1000 websites, so you will find it in virtually every data center. NGINX is recognized for its performance, stability, rich feature set, simple configuration, and low resource consumption.
