How to Install PHP 7.x on CentOS 8 For Nginx

To install PHP 7.x on CentOS 8 for Nginx, you can use the following steps:

1. Add the repository for PHP 7.x:

sudo dnf install https://rpms.remirepo.net/enterprise/remi-release-8.rpm

This will add the Remi repository to your system, which contains packages for PHP 7.x.

2. Enable the Remi repository:

sudo dnf module enable php:remi-7.4

Replace 7.4 with the version of PHP you want to install (e.g., 7.3 or 7.2).

3. Install PHP and the PHP-FPM package:

sudo dnf install php-fpm

This will install the latest version of PHP and the PHP-FPM package available in the repository.

4. Start the PHP-FPM service and enable it to start automatically on boot:

sudo systemctl start php-fpm
sudo systemctl enable php-fpm

5. Configure Nginx to use PHP-FPM:

Edit the Nginx configuration file (e.g., /etc/nginx/nginx.conf) and add the following lines in the server block:

location ~ \.php$ {
    include fastcgi_params;
    fastcgi_pass unix:/run/php-fpm/www.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}

Save the file and reload the Nginx configuration:

sudo nginx -s reload

6. Test the installation:

Create a PHP file in the document root of your web server with the following code:

test.php

<?php
phpinfo();
?>
