How to install phpMyAdmin on CentOS, Red Hat, and Fedora

The phpMyAdmin application adds a browser interface to an existing MySQL or MariaDB server, so the package source and web-server defaults matter as much as the application files. On Red Hat-family systems, distribution packages integrate it with Apache and PHP-FPM while keeping updates under DNF.

Current Fedora repositories ship phpMyAdmin directly. CentOS Stream 9 and Red Hat Enterprise Linux 9 use EPEL, with separate repository preparation for each platform before the shared package-install step.

The packaged Apache policy accepts only local requests by default. A local HTTP 200 response from http://127.0.0.1/phpmyadmin/ proves that Apache, PHP-FPM, and phpMyAdmin are serving the login page without exposing the database console to the network.

1. Install the DNF repository plugin on CentOS Stream 9.

   $ sudo dnf install --assumeyes dnf-plugins-core

2. Enable the CRB repository on CentOS Stream 9.

   $ sudo dnf config-manager --set-enabled crb

3. Install the EPEL 9 release packages on CentOS Stream 9. Example output:

   $ sudo dnf install --assumeyes \
     https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm \
     https://dl.fedoraproject.org/pub/epel/epel-next-release-latest-9.noarch.rpm
   Installed:
     epel-next-release-9-11.el9.noarch
     epel-release-9-11.el9.noarch
   
   Complete!

1. Enable CodeReady Builder for the RHEL 9 architecture.

   $ sudo subscription-manager repos --enable codeready-builder-for-rhel-9-$(arch)-rpms

2. Install the EPEL 9 release package on RHEL 9.

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

1. Install phpMyAdmin and Apache from the enabled DNF repositories.

   $ sudo dnf install --assumeyes phpMyAdmin httpd

   Fedora users begin here because the phpMyAdmin package is already available from Fedora's enabled repositories.

2. Test the packaged Apache configuration.

   $ sudo apachectl configtest
   AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 192.0.2.10. Set the 'ServerName' directive globally to suppress this message
   Syntax OK

3. Enable PHP-FPM with immediate startup.

   $ sudo systemctl enable --now php-fpm

4. Enable Apache with immediate startup.

   $ sudo systemctl enable --now httpd

5. Confirm the local phpMyAdmin endpoint returns HTTP 200.

   $ curl --head http://127.0.0.1/phpmyadmin/
   HTTP/1.1 200 OK
   Server: Apache/2.4.68 (Fedora Linux)
   X-Powered-By: PHP/8.5.8
   X-Robots-Tag: noindex, nofollow

   The packaged /etc/httpd/conf.d/phpMyAdmin.conf uses Require local. Remote access needs a separate policy limited to trusted clients and protected with HTTPS.
