I followed https://www.theurbanpenguin.com/installing-devstack-on-ubuntu-16-04/ tutorial to install devstack(queens release) on my Ubuntu 16.04 server.
After the installation was done I ran the following commands
export OS_USERNAME=admin
export OS_TENANT_NAME=admin
export OS_PASSWORD=<password>
export OS_AUTH_URL=http://server-ip:5000/v2.0
openstack image create --public --disk-format qcow2 --container-format bare --file /home/cse3/ubuntu_images/ubuntu-14.04-server-cloudimg-amd64-disk1.img ubuntu
But whenever I open http://server-ip:5000/v2.0 in my browser I am getting unable to connect error. When I create an image from the command line I get the following message
Failed to discover available identity versions when contacting http://server-ip:5000/v2.0. Attempting to parse version from URL.
Unable to establish connection to http://server-ip:5000/v2.0/tokens: HTTPConnectionPool(host='server-ip', port=5000): Max retries exceeded with url: /v2.0/tokens (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f84ebecabd0>: Failed to establish a new connection: [Errno 111] Connection refused',))
Can anyone suggest what steps need to be followed to remove this error?
After installing the Devstack, you should be able to view the OpenStack dashboard at http://server-ip if the server-ip is a public IP. The AUTH_URL is for you to authorize the API when you are using the SDK or the client library. And this is actually how the dashboard (Horizon) works with the Keystone identity service.
If the server_ip is not a public IP, you need to set up a proxy port in your server and your browser.
