I have no experience in openstack and would appreciate anyone who can help and guide me with this issue. I'm installing openstack in virtual environment (Ubuntu 12.04) and this came out:
- git clone git//git.openstack.org/openstack/requirements.git/opt/stack/reqiurements Cloning into '/opt/stack/requirements'... fatal:unable to connect to git.openstack.org: git.openstack.org[0: 192.237.223.224]: errno=Connection refused git.openstack.org[1: 2001:4800:7813:516:3bc3:d7f6:ff04:aacb]: errno=Network is unreachable
I had the same problem, the git protocol is blocked in my testing environment.
The solution is to modify the sourcerc file in the devstack installation folder to use https instead of git. You have to look for that line and change it. This file is also known as the local.conf file.
Default setting in sourcerc file:
GIT_BASE=${GIT_BASE:-git://git.openstack.org}
Modified setting that should bypass git restrictions:
GIT_BASE=${GIT_BASE:-https://git.openstack.org}
Simply add this modified line to the local/localrc section of your local.conf file in the DevStack directory and it should use the HTTPS protocol instead of the Git protocol! More info on the local.conf file here - http://devstack.org/configuration.html
Make change in stackrc :
-GIT_BASE=${GIT_BASE:-git://git.openstack.org}
+GIT_BASE=${GIT_BASE:-https://www.github.com}
This would solve problem for you.
Sorry, can't help you with your particular error, but in general, the easiest way to install openstack is http://devstack.org/

This manual is about OpenStack together with Ironic project, but it won't affect you anyway. And you can omit "Install ironic client" step.
In the git clone command replace the protocol - git:// with http://, in the repository URL and try. May be the network, to which your machine is connected, is prohibiting the git protocol.
Changing to "http" worked for me.
This is my custom bash script to install openstack ocata. It covers the installation of openstack core projects which includes keystone, nova, glance, nova, neutron and horizon dashboard.
Please follow the instructions in the document and execute the script in your environment. We can add additional compute node with this script.
