How to install PHP 7.4 With Nginx on Ubuntu 20.04

install php 7.4 with nginx on ubuntu 20.04

PHP is one of the most popular server scripting languages used for creating dynamic pages. Many popular CMS is written in PHP including, WordPress, Laravel, Magento, and many more.

The PHP 7.4 version was officially released on November 28th, 2019 with a number of new features. It has also few incompatibilities so you should take care before upgrading from the previous version.

In this tutorial, we will show you how to install PHP7.4 with Nginx on Ubuntu 20.04 server.

Prerequisites

  • An Ubuntu 20.04 VPS (we’ll be using our SSD 2 VPS plan)
  • Access to the root user account (or access to an admin account with root privileges)

Log in to the Server & Update the Server OS Packages

First, log in to your Ubuntu 20.04 server via SSH as the root user:

ssh root@IP_Address -p Port_number

You will need to replace ‘IP_Address‘ and ‘Port_number‘ with your server’s respective IP address and SSH port number. Additionally, replace ‘root’ with the username of the admin account if necessary.

Before starting, you have to make sure that all Ubuntu OS packages installed on the server are up to date. You can do this by running the following commands:

apt-get update -y
apt-get upgrade -y

Install Nginx

By default, the latest version of Nginx is available in the Ubuntu 20.04 default repository. You can install it with the following command:

apt-get install nginx -y

After installing Nginx, start the Nginx service and enable it to start at system reboot with the following command:

systemctl start nginx
systemctl enable nginx

You can also verify the installed version of Nginx using the following command:

nginx -v

You should get the following output:

nginx version: nginx/1.18.0 (Ubuntu)

Install PHP7.4

By default, Ubuntu 20.04 ships with PHP 7.4 in its upstream repositories. You can install it easily by just running the following command:

apt-get install php7.4 -y

Once the PHP is installed, verify the installed version with the following command:

php --version

You should get the following output:

PHP 7.4.3 (cli) (built: Oct  6 2020 15:47:56) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
    with Zend OPcache v7.4.3, Copyright (c), by Zend Technologies

PHP configurations related to Nginx is stored in /etc/php/7.4/fpm/php.ini file. You can modify it for better performance.

Install PHP7.4-FPM and Other Extensions

Nginx does not contain native PHP processing. So you will need to install PHP-FPM for processing the PHP files. FPM is an alternative PHP FastCGI implementation with some additional features useful for heavy-loaded sites.

You can install PHP7.4-FPM with other necessary extensions by running the following command:

apt-get install php7.4-fpm php7.4-cli php7.4-mysql php7.4-curl php7.4-json -y

Once all the packages are installed, start the PHP7.4-FPM service and enable it to start at system reboot:

systemctl start php7.4-fpm
systemctl enable php7.4-fpm

Configure Nginx to Process PHP Files

Next, you will need to configure Nginx to process PHP files.

To do so, create a new Nginx virtual host configuration file with the following command:

nano /etc/nginx/sites-available/example

Add the following lines:

server {
        listen 80;
        server_name test.example.com;
        root /var/www/html;
        index info.php;

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.4-fpm.sock;
    }
}

Save and close the file then enable the Nginx virtual host configuration file with the following command:

ln -s /etc/nginx/sites-available/example /etc/nginx/sites-enabled/

Next, verify the Nginx for any syntax error with the following command:

nginx -t

You should get the following output:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Finally, restart the Nginx service to apply the configuration changes:

systemctl restart nginx

Next, create a info.php file to verify the PHP version:

nano /var/www/html/info.php

Add the following code:

<?php phpinfo();

Save and close the file when you are finished.

Verify PHP

At this point, Nginx is configured to process PHP files. Its time to test it.

Open your web browser and type the URL http://test.example.com. You should see the following screen:
