Forbidden :You don’t have permission to access /phpmyadmin on this server

None of the configuration above worked for me on my CentOS 7 server. After hours of searching, that what worked for me:
Edit file phpMyAdmin.conf
sudo nano /etc/httpd/conf.d/phpMyAdmin.conf
And replace the existing … node with the following:

AddDefaultCharset UTF-8

# Apache 2.4

#Require ip 127.0.0.1
#Require ip ::1
Require all granted



# Apache 2.2
Order Deny,Allow
Deny from All
Allow from 127.0.0.1
Allow from ::1

On a fresh install on CENTOS7 I have tried the above methods (edit phpMyAdmin.conf and add Require all granted), it still does’nt work. Here is the solution : install the mod_php module :
$ sudo yum install php

then restart httpd :
$ sudo systemctl restart httpd

and voila !
