What Is Nginx? – Semalt Expert

Nginx [engine x] is another HTTP technique and reverse proxy server. Nginx functions as a mail proxy server, and a generic TCP/UDP proxy server, whereby it authenticates different web requesters to make a visitor reach a website. Igor Sysoev originally wrote this proxy server. Other hosting packages may use methods such as the LAMP stack (Linux + Apache + MySQL + PHP) to power WordPress. Nginx can be a powerful setup regarding revere proxy approach. Necessarily, there are many ways which webmasters can employ to implement Nginx. You can be able to use all of its features at the same time making use of the Apache server. Majority of the websites which are hosted on a Nginx server run on an Apache setup. There are HTTPS response headers as well as other proxies referring to it as the web servers.

This guideline by Michael Brown, the Semalt Customer Success Manager, explains the use of a standalone Nginx setup. Instead of relying on the apache server technique, you can use Nginx alone like the primary server. There may be some special considerations when implementing Nginx on WordPress. There is some crucial information which a user needs to know about Nginx. For instance:

  • All configurations are possible in the admin panel on the server level configuration. As a result, there is no directory-level configuration. Unlike Apache's .htaccess or IIS's web.config files, WordPress cannot modify a Nginx configuration.
  • The way permalinks function is a bit different on Nginx than on other Apache servers.
  • Nginx cannot generate the rewrite rules for you. Nginx does not have a .htaccess-type capability hence it is impossible to configure the server from a user end.
  • You use plugins to install your permalinks. It is essential to install an "index.php" which can form a panel for allowing modifications to your server.
  • For users who may want to gain some limited htaccess capability, they can install htscanner PECL extension for PHP. Unfortunately, this is only a developmental modification and can come with its complications. Ensure you have a robust debugging method before adopting this technique.

In this Nginx guideline, the assumption is that you have already installed Nginx. As a result, installation and instructions on how it operates are not inclusive.

Important information regarding Nginx

  • The Nginx helper maps map.conf file automatically whenever a new website is created. In some cases, you may need to reload Nginx manually to ensure the changes take to affect. Nginx also stores websites in a php-fpm form, whenever a new site is present.
  • Large websites can make use of Nginx as one can be able to multiple setup domains.
  • There are symbolic links, meaning that you do not need to worry about accidental deletes or adjustments in the entire server.


For website owners needing a reverse-proxy server, Nginx setup can be an essential approach. The entire configuration makes a common assumption that the root of the site or blog is present on the host. The point of reference is at the server level itself and not on the user side. People must modify the rules when they alter aspects of the website like adding a blog.
