How to Install PHP 8.2 in CentOS 9 Stream

---

PHP is a script language and interpreter that is freely available and used primarily on Linux Web servers.

To install PHP 8.2, we’ll need to add/enable the Remi RPM repositories which contain the PHP 8.2 packages that we need.

Pre-requisites :

• A system with CentOS 9 Stream installed and running.

• root access to the system.

First, let’s start by ensuring your system is up-to-date.

dnf update

Installing the EPEL and Remi Repository

---

For this, we use the PHP 8.2 packaged by Remi,

First, let us install the EPEL repository,

dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm

Next, install the Remi repository with the following command,

dnf install https://rpms.remirepo.net/enterprise/remi-release-9.rpm

Output:

[root@vps ~]# dnf install https://rpms.remirepo.net/enterprise/remi-release-9.rpm
