Once you adding the Remi repository, afterward you can proceed with the installation of PHP 8.2 on your Rocky Linux 9. Run the following command:
[samm@php82 ~]$ sudo dnf install php
When you enable the Remi PHP repository on your system, you’re laying the groundwork to install the PHP version that suits your needs. The available options provide you with flexibility, allowing you to seamlessly integrate with either Apache or Nginx. Additionally, those with the required expertise can amplify functionality by integrating tailored extensions that align precisely with their CMS or software development project needs.
Nginx PHP :
[samm@php82 ~]$ sudo dnf install php-fpm php-cli -yApache (httpd) PHP :
[samm@php82 ~]$ sudo dnf install php php-cli -yCheck for the currently active version of PHP with the following command:
[samm@php82 ~]$ php -v
PHP 8.2.8 (cli) (built: Jul 4 2023 14:52:54) (NTS gcc x86_64)

In addition to PHP itself, you may find it necessary to install extra PHP modules. To do this, you can make use of the following command. Just replace [module-name] with the specific package you want to install:
Moreover, the option exists to install multiple packages concurrently. Below following are some suggestions for the most commonly required modules you might consider installing:
[samm@php82 ~]$ sudo dnf install php-cli php-fpm php-curl php-mysqlnd php-gd php-opcache php-zip php-intl php-common php-bcmath php-imagick php-xmlrpc php-json php-readline php-memcached php-redis php-mbstring php-apcu php-xml php-dom php-redis php-memcached php-memcacheYou can run the following command to list all currently loaded PHP modules:

Zend OPcacheAdditionally, you can create a sample php file in the /usr/share/nginx/html/ folder as shown:
[samm@php82 ~]$ sudo vi /usr/share/nginx/html/info.phpThen add the following PHP code which will populate the version of PHP alongside installed modules.
<?php
phpinfo();
?>Remember to save your changes and exit the file. Afterward, make sure to restart the Nginx web server, as demonstrated below:
[samm@php82 ~]$ sudo systemctl restart nginx.serviceThen, open your web browser and go to the your ip address:
http://server-ip/info.php
The webpage offers a comprehensive array of information about the installed PHP version. This information includes details such as the build date, build system, architecture, and an extensive list of PHP extensions.
Finally, you should see a PHP info page displaying detailed information about your PHP installation.
Step 5: Using PHP 8.2 with Nginx on Rocky Linux 9
We will explore web server configurations for both Nginx and Apache to effectively host your PHP application.
PHP Application with Nginx web server
Another key point in the Nginx environment, PHP code is typically handled by a separate process known as PHP-FPM (FastCGI Process Manager). PHP-FPM acts as a kind of background service that’s always ready to process PHP requests as they come in. In this configuration, Nginx acts as a bridge, sending incoming requests over to PHP-FPM for smooth execution .
Initially, you need to install php-fpm.
[samm@php82 ~]$ sudo dnf install php-fpmOpen your Nginx server configuration and incorporate the following block within the existing http block. This addition will configure the Nginx server to forward PHP requests to PHP-FPM for execution, indeed.
[samm@php82 ~]$ sudo vi /etc/nginx/conf.d/samm.conf### HTTP ###
server {
listen 8080;
listen [::]:8080;
server_name samm.com;
root /opt/app-samm;
index index.html index.htm index.php;
location / {
try_files $uri $uri/ /index.php?$query_string;
index index.html index.htm index.php;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/run/php-fpm/www.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location ~ /\.ht {
deny all;
}
}Validate Nginx configuration is ok.
[samm@php82 ~]$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successfulAfter making these changes, then restart the Nginx web server.
[samm@php82 ~]$ sudo systemctl restart nginxPHP Application with Apache web server
Meanwhile, combining PHP with the Apache web server on Rocky Linux opens up possibilities for building dynamic and interactive web applications. In this tutorial, we’ll take you through the process of setting up PHP alongside Apache on your Rocky Linux system.
Once PHP is installed, the next step is to configure Apache to handle PHP files appropriately. To achieve this, open the Apache configuration file using your preferred text editor. For example, we’ll use the vim text editor:
[samm@php82 ~]$ sudo vi /etc/httpd/conf.d/sammlinux.confInside the file, you can define your virtual host. Here’s a basic example:
<VirtualHost *:80>
ServerAdmin [email protected]
ServerName www.sammlinux.com
ServerAlias sammlinux.com
DocumentRoot /var/www/sammlinux
ErrorLog /var/log/httpd/sammlinux.com-error.log
CustomLog /var/log/httpd/sammlinux.com-access.log combined
</VirtualHost> Then, save the changes and exit the text editor.
After that you can create a sample index.html file to test the webserver.
[samm@apache ~]$ sudo vi /var/www/sammlinux/index.htmlPaste the following lines in the file.
<html>
<head>
<title>Welcome to sammlinux.com!</title>
</head>
<body>
<h1>Congratulation! The virtual host for <span style="color:blue; font-size: 24px;">sammlinux.net</span> is now up and running!</h1>
</body>
</html>Then save the file and exit the text editor.
Once you’ve made adjustments to the Apache configuration, be sure to restart the Apache service to ensure the changes take effect:
[samm@php82 ~]$ sudo systemctl restart httpdEventually to ensure that PHP is working correctly with Apache, create a test PHP file in your web directory. Use the following command to create the file:
[samm@php82 ~]$ sudo vi /var/www/html/info.phpAdd the following PHP code to the file:
<?php
phpinfo();
?>Then save the file and exit the text editor.
Open a web browser and navigate to http://your_server_ip. You should see a page displaying detailed information about example of your newly configured virtual hosting page.
