Installing phpMyAdmin onto Amazon EC2 instance

I've configured my EC2 instance as a LAMP, following Amazon's tutorial. That appears to be functioning correctly (I can see phpinfo() in a file I've uploaded OK).

I then tried to install phpMyAdmin by doing the following:

sudo yum --enablerepo=epel install phpmyadmin

I can see that phpMyAdmin is now in /usr/share/phpmyadmin, so I added an symbolic link:

sudo ln -s /usr/share/phpmyadmin /var/www/html/phpmyadmin

I then edited http.conf to add AllowOverride all to <Directory "/var/www/html">.

And then restarted the server:

sudo service httpd restart

But whenever I visit http://ift.tt/1u8GLGM I get a 403 Forbidden response from the server: You don't have permission to access /phpmyadmin on this server.

I feel like I'm missing something really obvious, but I cannot figure out what.
