@psychobunny Ok. I will start the translation of the docs this afternoon because in UTC+2, it's 1H AM.

@velderia I have managed : http://nodebb-129968.euw1.nitrousbox.com:4567
Details of the installation :

• RAM : 640 MB
• Region host : Europe
• Storage : 1000 MB

Nice :o, it looks like Github ^^.

Good job, i like this !

This guide : https://docs.nodebb.org/en/latest/installing/os/windows8.html doesn't work on Windows Azure ?

I was interested by LevelDB because I searched on google and on the project page, the author said that LevelDB is fast and lightweight.

I tried to use leveldb on a debian machine. But it does not work.
I got this error :

error: Unable to initialize Level DB! Is Level DB installed? Error :Cannot read property 'Store' of undefined

Note : I ran the setup with root user.

@psychobunny Added Nitrous.IO : https://github.com/NodeBB/NodeBB/pull/1836

unixfox created this issue in NodeBB/NodeBB

closed Update guide openshift with redis and added nitrous.io #1836
