Blank page after install on CentOS 6.6

安装

I’m trying to install Discourse on CentOS 6.6 running on my VM on my local box. I’ve followed instruction on http://www.howtoinstalldiscourse.com/how-to-install-discourse-on-centos/. I got it running, but all i got is a blank page with these errors on my Chrome developer tools console:

GET http://localhost.newlum:85/assets/preload_store-df49ca825a94fb1f1c180909abe34900.js
GET http://localhost.newlum:85/assets/locales/en-4091e96b228c0c127f871d1f56ea5fa1.js

Uncaught ReferenceError: Discourse is not defined(anonymous function)
GET http://localhost.newlum:85/assets/browser-update-fd9405eb2b168d517a8ab2e955a292e2.js

I don’t think the js files are loaded properly, maybe some kind of permission issue, but have no idea how to fix, as I’ve never used docker or nginx. If you can give me some pointer would be great. thanks!

I doubt Docker is installed correctly.

What does docker --info and docker --version report?

Devicemapper is not supported. It’s super buggy in Docker. You need AUFS working.

Also that’s an old version of Docker, the current version is 1.6.1 or higher.
