PhpMyAdmin is the most popular web-based client for managing MySQL servers. PHPMyAdmin is written in the PHP programming language. It provides a user-friendly web interface to access and manage MySQL databases. This article will introduce installing phpMyAdmin on Fedora system.
#Conditions: We assume that the Apache (HTTP) web server, PHP and MySQL database server have been installed on the system.
Step 1: Configure REMI Repository
The latest packages for phpMyAdmin can be found in the Remi repository. Use the following command to install it in your system.
### Fedora 28 $ sudo rpm -Uvh http://rpms.famillecollet.com/fedora/remi-release-25.rpm ### Fedora 27 $ sudo rpm -Uvh http://rpms.famillecollet.com/fedora/remi-release-27.rpm ### Fedora 26 $ sudo rpm -Uvh http://rpms.famillecollet.com/fedora/remi-release-26.rpm
Step 2: Install phpmyadmin
After enabling the Remi repository on your system, let us install phpMyAdmin using the yum package manager. All dependencies will be installed automatically.
$ sudo dnf --enablerepo=remi,remi-test install phpMyAdmin
Step 3: Allow remote access
By default, phpMyAdmin only allows access from localhost. If you want to make it accessible from a remote machine, edit phpMyAdmin's Apache configuration file.
$ sudo vi /etc/httpd/conf.d/phpMyAdmin.conf
Now check the following sections. Change Require local to Require all granted, this will disable local restricted access and make phpMyAdmin accessible from the network.
Alias /phpMyAdmin /usr/share/phpMyAdmin Alias /phpmyadmin /usr/share/phpMyAdmin <Directory /usr/share/phpMyAdmin/> AddDefaultCharset UTF-8 <IfModule mod_authz_core.c> # Apache 2.4 Require all granted </IfModule> <IfModule !mod_authz_core.c> # Apache 2.2 Order Deny,Allow Deny from All Allow from 127.0.0.1 Allow from ::1 </IfModule> </Directory>
After making any changes in the Apache configuration file, the Apache service must be restarted to reload the updated settings.
$ sudo service httpd restart
Step 4: Access phpmyadmin in your browser
Now, you can access phpmyadmin in your browser using the following URL. The remote user changes localhost with the system IP address.
http://localhost/phpMyAdmin/
