What is Nginx, and What Benefits Does It Provide?

Nginx is a server software used to create web applications, present content on the Internet, and host websites amongst other things. It is an incredibly powerful open source web server, known for its small memory footprint and good scalability. Nginx is popular for its ease of use, great performance, and low resource consumption. It is also used to reverse-proxy requests from other web servers, such as Apache or Lighttpd, and by developers and system administrators to provide a secure, stale, and Content Delivery Network (CDN). Although it’s popular for serving static content, Nginx is also great for hosting dynamic web applications.

Nginx is fast and it quickly becomes the go-to server software for many webmasters. It is especially suitable for high-load websites, as it can handle thousands of simultaneous connections without major performance impact. Nginx is available on most platforms, including Windows and Mac. It is also easy to setup and maintain with minimal configuration.

The main benefits of using Nginx are performance, security, cost-efficiency, ease of use and scalability. Websites hosted on Nginx are faster, as Nginx generally processes HTTP requests quicker than other web servers. This makes it ideal for hosting high-traffic websites and applications. Furthermore, Nginx is more secure against attacks and cyber threats, and it supports shared hosting on a single server with greater redundancy and scalability.

What Version of PHP Are You Using?

Using the most current version of PHP is always recommended. Many web-hosting providers provide support for PHP 7.2 and above. For those requiring more security, PHP 8 is now available. PHP 8 is the latest, most secure version of PHP that is designed to provide greater speed and reliability. Additionally, the latest versions of PHP are more efficient than previous versions, making them more reliable to use for web applications, ecommerce websites and online stores.

The support for different versions of PHP largely depends on the Nginx version and the operating system. For the most part, all versions of Nginx can be used to run a variety of PHP versions. The only exception is Nginx 1.4 which is not compatible with PHP 7.4 or higher. Older versions of Nginx may not be compatible with the latest versions of PHP.

How to Install 3 Versions Of PHP On Nginx?

Installing multiple versions of PHP on Nginx is easy. To start, make sure the Nginx server is installed and running. Then, install the necessary packages by running the following commands:

  • sudo apt-get update
  • sudo apt-get install php5 php7.1 php7.2

Next, create a configuration file for each version of PHP. The following is an example of a configuration file for PHP 7.1:

upstream php-handler {

server {
listen 80;
server_name localhost;
root /var/www/html/;
index index.php;

location ~ .php$ {
include fastcgi.conf;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;
fastcgi_pass php-handler;
location / {
try_files $uri $uri/ =404;

Save the file as php7.1.conf in the /etc/nginx/sites-available/ directory and also create php7.2.conf and php5.conf. Once all of the configuration files are created, run the following command to enable the configurations:

sudo ln -s /etc/nginx/sites-available/php7.1.conf /etc/nginx/sites-enabled/
sudo ln -s /etc/nginx/sites-available/php7.2.conf /etc/nginx/sites-enabled/
sudo ln -s /etc/nginx/sites-available/php5.conf /etc/nginx/sites-enabled/

The commands above will create symbolic links for each of the configuration files. The symbolic links will allow Nginx to serve requests from the different versions of PHP. Finally, restart the Nginx server to apply the changes with the following command:

sudo /etc/init.d/nginx restart

What Are The Pros and Cons Of Multiple Version Installation?

Installing multiple versions of PHP on Nginx has both advantages and disadvantages. The most obvious advantage is the increased flexibility that it provides. By having multiple versions of PHP installed on your Nginx server, you can easily switch between them to test functionality or quickly update the codebase. It also makes troubleshooting easier as the different versions can be analysed separately.

Multiple version installation also has its downsides, namely increased complexity and performance overhead. Managing multiple versions of PHP can be difficult and it is essential to keep track of security patches and ensure each version is up to date. Additionally, Nginx may require extra resources to manage multiple versions of PHP.

How to Monitor Nginx Usage?

Keeping track of server performance is important to ensure optimal performance and to pinpoint potential issues. To monitor Nginx usage, you can use any of the following tools:

  • Webmon – a real-time web-monitoring service which allows you to monitor Nginx performance using graphs and charts.
  • Google Analytics – a powerful analytics tool that helps you track web traffic, identify user engagement and more.
  • New Relic – a comprehensive performance monitoring solution for applications.
  • Psacct/Acct – an accounting system that helps you track Nginx usage and performance.

It is important to monitor Nginx usage regularly to ensure your server is running optimally. Additionally, monitoring your Nginx server can also help you identify potential security issues and address them quickly.


Installing multiple versions of PHP on Nginx is relatively easy and provides greater flexibility and security for web applications. Although, it may add complexity and require more resources. Properly monitoring Nginx usage and performance is essential to ensure optimal performance and security.
