@Bri Yes I did. I follow this guide to install nodebb:CentOS 6/7 — NodeBB 1.x documentation
I installed node 7.0.0
So I am doing the host myself on Digital ocean route.
I was following this guide.
And I got as far as the "setup" for nodeBB itself.
Then I get This error:
19/9 23:39  - error: Your Redis version is not new enough to support NodeBB
How do I go about updating the Redis version inside of this node
Redis will not update to the latest version on Ubuntu since (if I'm correct) it isn't updated to the latest version on apt-get, to fix this you need to uninstall redis and follow this guide to manually compile and install the new Redis version.
A simpler way to get a newer version:
$ sudo add-apt-repository ppa:chris-lea/redis-server $ apt-get update $ apt-get install redis-server
Will attempt the simpler way posted by Julian here in the next hour.
I will update you, and thanks very much for help so far! Hope to gain some experience in node myself and be able to contribute back.
