I am very pleased to present the installation script for Officeonline without limitations and Docker.
We tested it on Debian 8.7, Ubuntu 14.04 and Ubuntu 16.04. Just Download the script and run it as sudo or root.
I advise you to use HAProxy (I will integrate it in the script soon).
Just run the script and do not stop it. It will take 2-8 hours (It depends on the speed of your serve) to install everything you need to use it with Owncloud. You just have to replace SSL Certificates and key in /etc/loolwsd/.
I would like to thank community members for supporting me and testing.
