Centos 9 is a popular Linux distribution that is widely used for servers and other enterprise applications. One of the most important components of any web server is the programming language that it uses. In this tutorial, we will show you how to install PHP, one of the most widely used programming languages, on a Centos 9 server.

Before you begin, you will need to have a Centos 9 server up and running. You can either use a physical server or a virtual machine. You will also need to have root access to the server.

Step 1: Update the Server

Before we begin installing PHP, it is important to update the server to ensure that all the packages are up-to-date. You can do this by running the following command:

sudo yum update

Step 2: Install PHP

Now that the server is updated, we can go ahead and install PHP. You can do this by running the following command

sudo yum install php

This command will install the latest version of PHP that is available in the Centos 9 repository.

Step 3: Verify the Installation

Once the installation is complete, you can verify that PHP is installed and running by running the following command:

php -v

This command will display the version of PHP that is currently installed on the server.

Step 4: Configure PHP

After PHP is installed, you will need to configure it to work with your web server. The most popular web servers are Apache and Nginx. In this tutorial, we will show you how to configure PHP to work with Nginx.

First, we will create a new PHP-FPM pool by creating a new file in the /etc/php-fpm.d directory.

sudo nano /etc/php-fpm.d/www.conf

In this file, you will need to configure the user and group that PHP-FPM will run as, as well as other settings. Once you have made the necessary changes, save the file and exit.

Next, we will configure Nginx to work with PHP-FPM. To do this, we will create a new server block in the Nginx configuration file.

sudo nano /etc/nginx/conf.d/default.conf

In this file, you will need to add the following code to the server block:

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

This code tells Nginx to pass all requests for PHP files to PHP-FPM, which will then handle the request.

Step 5: Restart Services

After you have configured PHP and Nginx, you will need to restart both services to apply the changes. You can do this by running the following command:

sudo systemctl restart php-fpm
sudo systemctl restart nginx

Congratulations! You have now successfully installed PHP on your Centos 9 server and configured it to work with Nginx.
