In reference to this guide:
I have followed the guide to install Magento2 into a RHEL 7.2 server word-for-word, however, have not managed to get past the permissions check within the setup wizard.
As per the screenshot below, the permissions as far as I can see, are set correctly and the directories are writable by the Apache user, however, the check just fails.
I have run a further test by temporarily changing the permissions on one folder to 777, however, this also has no effect and still shows up as failed, so I can't help thinking there's something I've missed. I've spent 2-3 hours on this already so have finally given up.
Please see the below screenshot as a reference to my setup:
