问题
After changing proxy settings in open_uri.rb and server_manage.rb I finally managed to install neo4j behind a proxy server. The neo4j server is running on port 7000 ( It opens in the browser) but when i enter :
$rails generate scaffold post title body
Error:
/.rvm/gems/ruby-2.2.3/gems/neo4j-core-5.1.6/lib/neo4j-server/cypher_session.rb:51:in `open': Server not available on http://localhost:7000 (response code 403) (RuntimeError)
What should I do ? Any help is appreciated!!
$ ruby --version
ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-linux]
$ rails --version
Rails 4.2.2

My guess - proxy issues. Things may behave differently in your browser and code (because those are 2 different environment).
To check what exactly is going on with your database, you should try to make request to Neo4j manually, from command line.
Example with using curl:
# if auth enabled
curl -i --user username:password http://localhost:7000/db/data/
# if auth disabled
curl -i http://localhost:7000/db/data/
This will give you more details on what exactly is not working.
Also you can assemble basic ruby script that will make HTTP request, to check what you receive in response in this case.

A 403 might mean that your Neo4j authentication credentials are wrong. See http://neo4jrb.readthedocs.org/en/5.1.x/Setup.html#rails-configuration for details but basically, adding something like this to application.rb might do the trick:
config.neo4j.session_options = { basic_auth: { username: 'foo', password: 'bar'} }
Also, since you mentioned needing help with the proxy, you can add an initialize key to set that.
init = { proxy: { uri: 'http://myproxy', user: 'username', password: 'password' }}
auth = { username: 'neo4j', password: 'pwhere'}
config.neo4j.session_options = { basic_auth: auth, initialize: init }
