PHP 8.4 is not yet ready for production release but alpha releases are there for testing and sharing feedback with the development team. In this article we will install PHP 8.4 on Rocky Linux / AlmaLinux and the same process should apply for CentOS Stream flavors 9 or 8. In the last article we covered installation of PHP 8.4 on Ubuntu Linux. For the expected changes and features of PHP 8.4, check out the following links / resources:
It’s also a good practice to perform this installation on a newly provisioned instance of Rocky / AlmaLinux to avoid breaking you active system with applications serving live traffic.
Add EPEL and REMI repositories
First, we need to add EPEL and REMI repositories into the system.
- Add EPEL repository
sudo dnf -y install epel-release- Install REMI repository
## EL 9-based systems ##
sudo dnf install -y https://rpms.remirepo.net/enterprise/remi-release-9.rpm
## EL 8-based systems ##
sudo dnf install -y https://rpms.remirepo.net/enterprise/remi-release-8.rpmValidation can be done by listing available repositories in the system.
$ sudo dnf repolist
repo id repo name
appstream Rocky Linux 8 - AppStream
baseos Rocky Linux 8 - BaseOS
epel Extra Packages for Enterprise Linux 8 - x86_64
extras Rocky Linux 8 - Extras
remi-modular Remi's Modular repository for Enterprise Linux 8 - x86_64
remi-safe Safe Remi's RPM repository for Enterprise Linux 8 - x86_64You may be required to enable remi-safe repository which contain unstable software packages.
sudo dnf config-manager --set-enabled remi-safeInstall PHP 8.4 on Rocky / AlmaLinux / CentOS Stream
After the two repositories are added, the installation of PHP 8.4 can be done on your local system. To find out about the latest versions of PHP available in the system, run the following command:
sudo dnf module list phpInstall PHP 8.4 by running the command below:
sudo dnf install php84You will be prompted to accept installation, type y and press <ENTER>

Is this ok [y/N]: yNotice that this installation is from SCL and it is independent from your system, keeping the base OS safe. Few points to take note:
- The installation is under the /opt/remi/php84 directory
- Configuration files are placed inside the /etc/opt/remi/php84 directory
To get the version of PHP 8.4 installed, use the command:
