As an little update on this, i was able to get beyond that problem, by:
@ sudo apt-get install ruby-dev@

In order to get passenger working with my nginx, withouth having to recompile nginx again,
I decided to install a stand alone passenger version*, and use nginx as a reverse proxy.
Forwarding does work with (within nginx configuration)
proxy_pass http://127.0.0.1:4000;

• By running passenger like this:
  @ cd ~/openproject-ce@
  @ passenger start —daemonize —address 127.0.0.1 —port 4000 @

I am using a subdomain like:
op.domain.tld

which does serve the running passenger via nginx.
Sadly all i can see here does not look like openproject, but like some sort of misconfiguration :
'mysql2' database is not configured. Available: ["production", "adapter", "database", "host", "username", "password", "encoding"] (ActiveRecord::AdapterNotSpecified)

I uploaded this to pastebin, see: [ http://pastebin.com/Kb40ePHS ]

Now I am stuck again …. .
Looking forward to some help here :)

It seems, my config/database.yml was not correct,
i changed it, according to the ‘Manual Installation guide’.

And the error messages changed!
When i go to op.domain.tld, i get:

Action Controller: Exception caught

Sprockets::FileNotFound in Homescreen#index
Showing /home/openproject/openproject-ce/app/views/layouts/base.html.erb where line #43 raised:

couldn't find file 'bundles/openproject-global'
  (in /home/openproject/openproject-ce/app/assets/stylesheets/default.css.sass:28)

Rails.root: /home/openproject/openproject-ce

So, anyone got an idea what to do next?

Did you run the remaining rake tasks after your initial database issue?

The error stems from missing precompiled assets, which are built as follows:

[openproject@host] RAILS_ENV="production" ./bin/rake assets:precompile

An unrelated side note: Is there a reason why you can’t use the packaged installation method , or are you running some unsupported distro?

Best,
Oliver

Thanks for your answer.

I already tried that, sadly this did not help; as i said, i did everything stated by the manual, but used passenger as a stand alone version … .

I am on a Raspberry 2; there is no openproject package for this platform … .

Any ideas left?

Hey Mark,

this is definitely an issue with the webpack-based assets. Please make sure your npm/node installation works and try to check the output of the command I’ve linked you above. You may also want to manually run webpack in the frontend folder with $(npm bin)/webpack --progress.

What distro are you running on Raspberry? I must admit to have never tried that, but a debian/fedora flavor should work fine with our package.

Best,
Oliver

Hi Oliver,

Node version:

openproject@pi ~ $ node —version
v0.12.7

And once again:

openproject@pi ~/openproject-ce $ RAILS_ENV=“production” ./bin/rake assets:precompile
/home/openproject/openproject-ce/vendor/bundle/ruby/2.3.0/gems/fog-1.23.0/lib/fog/rackspace/mock_data.rb:42: warning: key “name” is duplicated and overwritten on line 80
$(npm bin)/webpack —config webpack.config.js
sh: 1: /home/openproject/openproject-ce/frontend/node_modules/.bin/webpack: not found

Tasks: TOP => assets:precompile => assets:compile_environment => assets:webpack

Running “$(npm bin)/webpack —progress” results in:

openproject@pi ~/openproject-ce/frontend $ $(npm bin)/webpack —progress
-su: /home/openproject/openproject-ce/frontend/node_modules/.bin/webpack: No such file or directory

Ok, something seems to be wrong here … .

What distro are you running on Raspberry? I must admit to have never tried that, but a debian/fedora flavor should work fine with our package.

I am using Rasobian 8 which is based on Debian 8; the problem is pi’s hardware, which is not supported. (no prebuilt packages)
