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 <Directory> ... </Directory> node with the following:

<Directory /usr/share/phpMyAdmin/>
   AddDefaultCharset UTF-8

   <IfModule mod_authz_core.c>
     # Apache 2.4
     <RequireAny>
       #Require ip 127.0.0.1
       #Require ip ::1
       Require all granted
     </RequireAny>
   </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>

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 !

You need to follow the following steps:

Find line that read follows

Require ip 127.0.0.1

Replace with your workstation IP address:

Require ip 10.1.3.53

Again find the following line:

Allow from 127.0.0.1

Replace as follows:

Allow from 10.1.3.53

Also find deny from all and comment it in the entire file.

Save and close the file.Restart Apache httpd server:

# service httpd restart

Edit: Since this is the selected answer and gets best visibility ... please also make sure that PHP is installed, otherwise you get same Forbidden error.
