Change phpMyAdmin alias to / on centos

Trying to remove the alias from the URL when accessing phpMyAdmin.

Edited the phpMyAdmin.conf file with "Alias / /usr/share/phpMyAdmin" but I get an error 403 when trying to access. I added "/db" instead of "/" and it works fine.

Alias /db /usr/share/phpMyAdmin
Alias / /usr/share/phpMyAdmin

Web page returns Error 403 Forbidden.
