extend couchdb part of "step-by-step"-guide #326
Description
When I tried installing cozy with the step by step guide on arch linux, the couchdb section was the first where I got problems. I think other people may encounter the same problems as well, so it might be a good idea to change some things:
on step 3) it says, that the command 'couchdb' should be available after installing couchdb. On arch linux this is not the case, and after doing a very quick google search, I did not get the impression that there's an official couchdb CLI. We should maybe use another method for the user to check if couchdb got correctly installed and is running fine.
on step 6.4) the curl command fails for me with the message you are not a server admin. I did not have couchdb installed before, it's a fresh installation. It would be cool if the docs had a plan B for that case.
I, for example, visited the admin interface of couchdb manually and added the administrator there.
on step 8.3) starting data-system fails, because it wants to connect to a couchdb database called "cozy", which did not exist in my case, and in the quide it looks like there is no command to add it. After adding the databse, i was able to start the data-system and the 2 other apps.
step 9) Even though I was able to start the 3 apps, including the controller, visitting localhost:9104 just tells me {"error":"Error: { error: 'not_found: missing' }","trans":"Error: { error: 'not_found: missing' }"}, so I'm stuck here at the moment.
