Download and extract PHPMyAdmin package

dnf install zip unzip -y
cd /usr/share/
wget https://files.phpmyadmin.net/phpMyAdmin/5.0.1/phpMyAdmin-5.0.1-all-languages.zip
unzip phpMyAdmin-5.0.1-all-languages.zip
mv phpMyAdmin-5.0.1-all-languages phpmyadmin

Now create tmp directory and set the appropriate permissions for phpmyadmin directory using below commands.

mkdir /usr/share/phpmyadmin/tmp
chown -R apache:apache /usr/share/phpmyadmin
chmod 777 /usr/share/phpmyadmin/tmp

Next, edit the config.sample.inc.php file using below commands

cd /usr/share/phpmyadmin
cp config.sample.inc.php config.inc.php
vi config.inc.php

Now find below line and enter root password in quotes

$cfg[‘blowfish_secret’] = ‘your-secure-password’;

also add below lines for caching in same file.

$cfg[‘TempDir’] = ‘/tmp/’;

then save changes to file and exit

After that we need to configure Apache for PHPMyAdmin so that it can be accessible. use below command to edit its configuration file.

vi /etc/httpd/conf.d/phpmyadmin.conf

and add below lines in this file.

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

   <IfModule mod_authz_core.c>
     # Apache 2.4
     <RequireAny>
      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>

<Directory /usr/share/phpmyadmin/setup/>
   <IfModule mod_authz_core.c>
     # Apache 2.4
     <RequireAny>
       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>

Finally save changes to file and exit.

Restart Apache web server

systemctl restart httpd

Now open your web browser and type below URL, do not forget to replace your server ip address. You should see similar page

http://SERVER-IP/phpmyadmin

Enter your login information to login PHPMyAdmin.
