I am using a Fedora Linux droplet and successfully installed the web environment. My PHP script connects to a separate MySQL server which works on the c9.io development environment, but on my website i get the error: Connection failed: Permission denied. How do I configure my Linux droplet so that it allows external connections? You can see the error here: http://cjmurphy.online/invapp/cp.php
I have only gone as far as installing PHP and Apache, I’ve made no other changes to my droplet.
