The original poster shared this Apache config this in the comments:
 <Directory "/usr/share/phpmyadmin"> # Order Deny,Allow # Deny from all Allow from 127.0.0.1 </Directory> Alias /phpmyadmin /usr/share/phpmyadmin Alias /phpMyAdmin /usr/share/phpmyadmin Alias /mysqladmin /usr/share/phpmyadmin 
 That’s your problem. You are trying to install phpMyAdmin manually in the main /var/www/html directory. But this Apache config has three aliases that would override that. The phpMyAdmin in /usr/share/phpmyadmin is actually the standard RPM package install location.
 So if you want to you can just comment out those Alias lines like this. Heck, comment out the <Directory> stuff as well:
 # <Directory "/usr/share/phpmyadmin"> # Order Deny,Allow # Deny from all Allow from 127.0.0.1 # </Directory> # Alias /phpmyadmin /usr/share/phpmyadmin # Alias /phpMyAdmin /usr/share/phpmyadmin # Alias /mysqladmin /usr/share/phpmyadmin 
 Restart Apache and then go to your URL of:
 http://the_url_of_your_site/phpmyadmin/ 
 And now the upgraded version you installed should load as expected.
 The other alternative is to rename /var/www/html/phpmyadmin to something like /var/www/html/phpmyadmin4 to get around that Alias. But you don’t need the Alias if you are installing directly into the web root of your server.
 EDIT: And if you want to upgrade the version of phpmyadmin in /usr/share, then keep those Alias directives in place but use the following modified instructions. Please double-check these before running:
   - cd /usr/share
- sudo mv phpmyadmin phpmyadmin-OLD NOTE: This is a backup of your old phpmyadmin just in case. Feel free to delete this phpmyadmin-OLDwhen you are sure you are in good shape with the new phpmyadmin.
- sudo wget https://files.phpmyadmin.net/phpMyAdmin/4.9.1/phpMyAdmin-4.9.1-all-languages.tar.gz
- sudo tar -xzvf phpMyAdmin-4.9.1-all-languages.tar.gz -C /usr/share
- sudo mv phpMyAdmin-4.9.1-all-languages phpmyadmin
- sudo rm phpMyAdmin-4.9.1-all-languages.tar.gz 
- sudo adduser phpmyadmin 
- sudo passwd phpmyadmin 
- sudo chown -R phpmyadmin:apache phpmyadmin/
- cd phpmyadmin
- mkdir config 
- chmod o+rw config 
- sudo cp config.sample.inc.php config/config.inc.php NOTE: Before re-installing I copy the config.inc.php in a directory,and after the installation I restore it from /config.inc.php config/config.inc.php) sudo chmod o+w config/config.inc.php service
- sudo httpd restart
 Just please note, there are a few things that are “wonky” but not dangerous about your instructions. For example, there was no sudo set before many commands. Maybe that was because it was in /var/www/html but I added sudo. Also your chown was 100% wrong with chown -R phpmyadmin.apache when that should be chown -R phpmyadmin:apache.
   
phpmyadmindirectory to another name (for examplephp-my-admin), then try to gohttp://your.web.site/php-my-admin/.
