I recently configured two servers. The first to use Apache and phpMyAdmin. On the other server I have a maria-DB server correctly configured.
phpMyAdmin it's reading the config file, but I can't connect to MariaDB server and PMA is throwing
#2002 Cannot log in to the MySQL server
Using mysql command to connect from the web server to the database server and using the same user/password, I can successfully connect to the database server.
No errors in mysql, all the ports for mysql are opened in the firewall, no php errors. I didn't have any luck finding the problem.
Edit:
Accesing the Server via Shell
[root@pw000i rafael]# mysql -h [IP ADRESS TO THE REMOTE SERVER] -u rafael -p
Enter password:

I'm using Fedora 20 on both servers. Any Ideas?

Solved, the guilty was SELinux.
