How to Install Remi RPM on Rocky Linux

Are you looking to install Remi RPM on Rocky Linux to unlock the latest versions of PHP, Memcached, Redis, and more? Remi’s RPM repository is a must-have for anyone running web servers or enterprise applications on Rocky Linux, offering fast access to up-to-date software that the default repositories often lack.

By following this guide, you’ll learn how to quickly add and enable the Remi RPM repository on Rocky Linux 10, 9, or 8. This ensures your system stays secure, compatible, and high-performing, whether you’re a developer needing the newest PHP features or a sysadmin focused on stability and security.

Updating Rocky Linux Before Importing the Remi RPM

Before installing new packages, make sure your Rocky Linux system is up to date. Upgrading existing packages minimizes the risk of conflicts during installation. Next, run the following command to refresh your system:

sudo dnf upgrade --refresh -y

This command upgrades all installed packages to their latest available versions.

Import the Remi RPM Repository on Rocky Linux

Remi requires the Code Ready Builder (CRB) repository (PowerTools on Rocky Linux 8) and EPEL (Extra Packages for Enterprise Linux) as dependencies. CRB provides development tools and libraries, while EPEL supplies additional packages Remi needs to function.

Choose the appropriate commands for your Rocky Linux version (10, 9, or 8) below.

Install dnf-plugins-core so the dnf config-manager commands work on minimal Rocky Linux systems:

sudo dnf install -y dnf-plugins-core

Importing the Remi PHP Repository for Rocky Linux 10

Rocky Linux 10 targets EL10 compatibility. First, enable the Code Ready Builder (CRB) repository:

sudo dnf config-manager --set-enabled crb

Next, install EPEL:

sudo dnf install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-10.noarch.rpm

Finally, install the Remi repository:

sudo dnf install -y https://rpms.remirepo.net/enterprise/remi-release-10.rpm

Importing the Remi PHP Repository for Rocky Linux 9

Rocky Linux 9 targets RHEL 9 compatibility and requires both the EPEL release and EPEL Next release packages. First, enable the Code Ready Builder (CRB) repository:

sudo dnf config-manager --set-enabled crb

Next, install both EPEL release packages:

sudo dnf install -y https://dl.fedoraproject.org/pub/epel/epel{,-next}-release-latest-9.noarch.rpm

Finally, install the Remi repository:

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

Importing the Remi PHP Repository for Rocky Linux 8

Rocky Linux 8 targets RHEL 8 compatibility and uses the PowerTools repository. First, enable the PowerTools repository:

sudo dnf config-manager --set-enabled powertools

If PowerTools is not recognized on your system, use the crb label instead:

sudo dnf config-manager --set-enabled crb

Next, install EPEL:

sudo dnf install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

Finally, install the Remi repository:

sudo dnf install -y https://rpms.remirepo.net/enterprise/remi-release-8.rpm

Rocky Linux is an RHEL-compatible distribution and does not require subscription management. Rocky Linux 10 and 9 use the crb (Code Ready Builder) repository, while Rocky Linux 8 uses powertools. Rocky Linux 9 requires both epel-release and epel-next-release packages per EPEL 9 requirements, while versions 10 and 8 only require the single epel-release package.

Enable Remi PHP Modules

Listing Available PHP Modules

With Remi enabled, you can access multiple PHP versions through DNF modules. This is particularly essential for developers supporting legacy applications on older PHP versions or leveraging the latest PHP features.

To see all available PHP versions, run this command:

sudo dnf module list php

Rocky Linux 9 - AppStream
Name     Stream       Profiles                     Summary
php      8.1          common [d], devel, minimal   PHP scripting language
php      8.2          common [d], devel, minimal   PHP scripting language

Remi's Modular repository for Enterprise Linux 9 - x86_64
Name     Stream       Profiles                     Summary
php      remi-7.4     common [d], devel, minimal   PHP scripting language
php      remi-8.0     common [d], devel, minimal   PHP scripting language
php      remi-8.1     common [d], devel, minimal   PHP scripting language
php      remi-8.2     common [d], devel, minimal   PHP scripting language
php      remi-8.3     common [d], devel, minimal   PHP scripting language
php      remi-8.4     common [d], devel, minimal   PHP scripting language

Hint: [d]efault, [e]nabled, [x]disabled, [i]nstalled

The output shows both the default Rocky Linux PHP modules and the additional versions available through Remi’s repository.

Choose Your PHP Version

PHP Version	Primary Focus	Best For	Active Support Until
PHP 8.2	Latest stable features and optimizations	New projects and actively maintained applications	December 2025
PHP 8.3	Cutting-edge features and performance improvements	Greenfield projects requiring the latest PHP capabilities	November 2026
PHP 8.4	Newest stable release with latest enhancements	Development environments and forward-looking production systems	November 2027

Enable your chosen PHP version. For example, to enable PHP 8.3:

sudo dnf module enable php:remi-8.3 -y

For other versions, replace 8.3 with 8.2 or 8.4 as needed.

Enable only one PHP module version at a time. If you have previously enabled a different PHP version, you must disable it first with sudo dnf module disable php:remi-[old-version] -y before enabling a new version to avoid module conflicts.

Verify the PHP module is enabled:

sudo dnf module list php | grep remi

Install and Verify PHP

Install the enabled PHP version:

sudo dnf install -y php

Verify the installation succeeded:

php --version

Once verified, if you’re running a web server, start the PHP-FPM service and enable it to start on boot:

sudo systemctl enable --now php-fpm

Verify PHP-FPM is running:

sudo systemctl status php-fpm

Enable Redis and Memcached from Remi RPM

Beyond PHP, Remi provides up-to-date versions of Redis and Memcached, two critical caching tools that improve application performance. In many cases, these packages are newer than what’s available in the default Rocky Linux repositories.

Enable and Install Memcached via Remi RPM

Memcached is a high-performance, distributed memory caching system that speeds up dynamic web applications by reducing database load. To begin, check available Memcached versions in Remi:

sudo dnf module list memcached

Next, enable the Memcached module and install it:

sudo dnf module enable memcached:remi -y

sudo dnf install -y memcached

Then, start and enable Memcached:

sudo systemctl enable --now memcached

Verify Memcached is running:

sudo systemctl status memcached

Enable and Install Redis via Remi RPM

Redis is an open-source, in-memory data structure store used as a cache, database, and message broker. To begin, check which Redis versions are available in Remi:

sudo dnf module list redis

Next, enable your desired Redis version. For example, to enable Redis 7.0:

sudo dnf module enable redis:remi-7.0 -y

Then install and verify Redis:

sudo dnf install -y redis

redis-cli --version

Finally, start the Redis service and enable it to start on boot:

sudo systemctl enable --now redis

Verify Redis is running:

sudo systemctl status redis

For deeper configuration and usage guidance for these tools, see the dedicated guides on installing PHP on Rocky Linux.

Troubleshooting Common Issues

If you encounter issues while installing or enabling Remi repositories, here are solutions to common problems:

Module Not Found Error When Enabling PHP

This occurs when you try to enable a PHP version that Remi doesn’t provide. Verify available versions:

sudo dnf module list php

Check that the version you want exists in the Remi repository list. Only enable versions shown with the remi- prefix (for example, remi-8.3, not just 8.3).

CRB Repository Not Enabled

EPEL installation fails if CRB isn’t enabled first. Verify CRB status:

sudo dnf repolist enabled | grep crb

If no output appears, CRB is disabled. Enable it:

sudo dnf config-manager --set-enabled crb

Verify it’s enabled:

crb            Rocky Linux 9 - CRB            enabled

Remi Repository Not Recognized

After installing Remi RPM, verify it’s properly enabled:

sudo dnf repolist | grep remi

Expected output shows multiple Remi repositories:

remi                 Remi's RPM repository               enabled
remi-modular         Remi's Modular repository           enabled
remi-safe            Safe Remi's RPM repository          enabled

If missing, reinstall the Remi release package that matches your Rocky Linux version (replace 9 with 10 or 8 as needed):

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

Module Enable Fails with Conflicting Versions

Attempting to enable a new PHP version while another is active produces this error:

Error: It is not possible to switch enabled streams of a module unless explicitly enabled via configuration option module_stream_switch.
It is recommended to rather remove all installed content from the module, and reset the module using 'dnf module reset <module_name>' command. After you reset the module, you can install the other stream.

Check which PHP module is currently enabled:

sudo dnf module list php | grep '\[e\]'

Disable the currently enabled version before enabling a new one:

sudo dnf module disable php:remi-8.2 -y

Then enable your desired version:

sudo dnf module enable php:remi-8.3 -y

Apply the same disable-then-enable approach if you encounter module conflicts when switching Redis or Memcached streams.

EPEL or Remi Repository Installation Fails

Download failures typically indicate URL mismatches or connectivity issues. Verify your Rocky Linux version:

cat /etc/rocky-release

Match the version number in the repository URL to your system version (8, 9, or 10). Test connectivity to the repository:

curl -I https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm

A successful response shows HTTP/2 200. Network errors or 404 responses indicate URL problems or connectivity issues.

Conclusion

You now have access to the Remi RPM repository on Rocky Linux, unlocking multiple PHP versions (8.2, 8.3, 8.4), up-to-date Redis and Memcached packages, and other enterprise-grade tools. This setup lets developers support legacy applications while using modern PHP features and helps system administrators maintain current caching infrastructure for high-performance deployments. Remember to enable only one PHP module version at a time and verify installations with the --version checks shown above to ensure your system is ready for production workloads.
