Learn to enable and use the Remi repository on RHEL 10 / CentOS 10 for installing modern PHP, MariaDB, and LAMP‑stack components safely and selectively.
The Remi repository offers up-to-date versions of popular server-side software—such as PHP, MySQL, and MariaDB—not typically included in the default Enterprise Linux distributions. Combining Remi with EPEL and the CodeReady Builder (CRB) repository lets you access cutting-edge packages while maintaining system stability on RHEL 10 or CentOS 10.

Let’s dive in.
Remi provides:
| Benefit | Description |
| Latest Builds | Access to modern PHP, MySQL, and MariaDB versions |
| Software Collections | Maintain multiple versions side-by-side |
| Selective Enabling | Enable the repo only when needed to avoid conflicts |
| Wide Coverage | Supports Enterprise Linux 10 (RHEL, CentOS Stream, etc.) |
✅ Prerequisites: Enable EPEL & CRB |
Before enabling Remi, ensure two vital repositories are active:
# 1. EPEL (Extra Packages for Enterprise Linux)
sudo dnf install -y epel-release
# 2. Enable CodeReady Builder (CRB) for RHEL systems
sudo subscription-manager repos --enable codeready-builder-for-rhel-10-$(uname -m)-rpms
These are required because Remi’s packages often depend on components within EPEL and CRB.
🔄 Option 1: Install Remi for RHEL 10 / CentOS 10 |
# 1. Install Remi repository
sudo dnf install -y https://rpms.remirepo.net/enterprise/remi-release-10.rpm
# 2. Optional: Clean cache
sudo dnf clean all && sudo dnf makecache
🔄 Option 2: Temporarily Enable Remi for Specific Packages |
# Install a specific package using Remi without enabling it permanently
sudo dnf --enablerepo=remi install <package-name>
🔄 Option 3: Permanently Enable Remi |
Edit /etc/yum.repos.d/remi.repo:
[remi]
enabled=1
[remi-safe]
enabled=1 # if needed
Then run:
sudo dnf repolist
This shows active Remi repositories alongside base repos.

🖥️ Example: Switch to Remi PHP 8.3 |
sudo dnf module reset php
sudo dnf module enable php:remi-8.3/common
sudo dnf install -y php php-cli php-fpm php-mysqlnd
🖥️ Example: Install PHP 8.4 as Software Collection |
sudo dnf install -y php84-php php84-php-fpm php84-php-mbstring
These commands leverage Remi’s modular structure to safely manage parallel versions.
# Enable Remi temporarily for installation
sudo dnf --enablerepo=remi install httpd mariadb-server php
# Start services
sudo systemctl enable --now httpd
sudo systemctl enable --now mariadb
| Strategy | Pros | Cons |
|---|---|---|
Temporary enable (--enablerepo) | Avoids overrides, safe | More typing, manual each time |
Permanent enable (enabled=1) | Convenient for frequent use | Risk of accidental system-wide overrides |
Using modules (php:remi-8.3) | Enables version control, stable | Requires familiarity with modular workflows |
🔧 Metadata or GPG issues? |
sudo dnf clean all && sudo dnf makecache
🔧 Dependency conflicts? |
sudo dnf --disablerepo="*" --enablerepo=remi install <package>
🔧 Module version misalignment? |
sudo dnf module reset php
sudo dnf module list php
