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.
It's because the identity API changed from
export OS_AUTH_URL=http://server-ip:5000/v2.0
to
export OS_AUTH_URL=http://server-ip/identity
You can get more from the OpenStack Doc
Check your httpd is running
systemctl status httpd
If it is exited or not started .
Enable the httpd
systemctk s

I have the following scenario:
server: Ubuntu 20.04.3 LTS
openstack installed with devstack
watcher 2.2.0
Every services seem to be working and i can see the watcher dashboard on localhost.
But I think I have an auth problem between watcher and keystone :
Error contacting Watcher server: Unable to establish connection
to http://x.x.x.x:9322/v1/services: HTTPConnectionPool(host='x.x.x.x', port=9322):
Max retries exceeded with url: /v1/services (Caused by NewConnectionError('<urllib3.connection.
HTTP Connection object at 0x7fba33b1be50>: Failed to establish a new connection: [Errno 111] Connexion refusée')).
Attempt 6 of 6
I'm testing something on a VM, I put the same IP and the same password everywhere
Where should I look first ?
I am trying on an application and previously it worked and the data was able to be persisted into MongoDB. But recenntly , we had a change of router and thus we went ahead to regenerate SDK and etc but we still has the connection error.
Error :
2017/01/26 9:24:27 [WARNING] [kaa_bootstrap_manager.c:612] (-7) - Could not find next Bootstrap access point (protocol: id=0x56C8FF92, version=1)

2017/01/26 9:24:27 [ERROR] [kaa_client.c:240] (-7) - Failed to process OUT event for the client socket 3
And thus , we went ahead with troubleshooting where one of the staffs i emailed passed me a link for troubleshooting .
https://kaaproject.github.io/kaa/docs/v0.10.0/Administration-guide/Troubleshooting/
I followed already but i had an error where im stucked with writing 'kaa-node restart' to restart the node service.
Here are the commands for troubleshooting:
Connect to your Kaa Sandbox via ssh:
$ ssh kaa#<YOUR-SANDBOX-IP>
password: kaa
Stop the Kaa service:
$ sudo service kaa-node stop
Clear the Kaa logs:
$ sudo rm -rf /var/log/kaa/*
Start the Kaa service:
$ sudo service kaa-node start
I typed 'sudo service kaa-node start'. it gave me:
kaa#kaa-sandbox.kaaproject.org:~$ sudo service kaa-node start
* Starting Kaa Node daemon (kaa-node):
/bin/bash: /var/log/kaa/kaa-node-server.init.log: Permission denied
Try verifying the Kaa host on the Management page. Also, the Sandbox Web UI (the Management page) is able to restart all the necessary Kaa services on the Sandbox after the Kaa host change.
Please note that the Kaa host should match the PC host IP address accessible from the network your applications are running in.
Please try and let me know if this works for you.
I installed cloudify3.4 according to the cloudify DOCS. When I install the manager, and executed like this:
# cfy bootstrap --install-plugins -p openstack-manager-blueprint.yaml -i openstack-manager-blueprint-inputs.yaml
an error occurred:
[ERROR] Workflow failed: Task failed 'fabric_plugin.tasks.run_script' -> Timed out trying to connect to 192.168.17.15 (tried 5 times)
I have already build a extern network 192.168.17.0/24 and I have already installed

cloudify_openstack_plugin-1.4-py27-none-linux_x86_64-redhat-Maipo.wgn
So, how to solve this error? Thank you to everyone who helped me!
It seems that you can't connect the manager.
Please make sure that you have an ssh connection from the CLI to the manager.
Since you are bootstrapping an Openstack manager you should make sure to have an external IP if you are outside of Openstack or that the CLI is on the same network if you are on Openstack.
I'm trying to deploy Openstack Icehouse on Ubuntu Server 14.04 by following the official document. But after Keystone\Nova\Neutron\Glance were deployed, when I tried to launch a CirrOS instance by
nova boot -nic ... -image ... -flavor ...
, it failed.
The log in Nova client shows that:
The Neutron client(Yes, it's neutron. I guess there are interactions between them in booting) tried to connect with Neutron server to create a port on tenant's network.
But Neutron client set up the token-getting request using {username:neutron, password:REDACTED} to Keystone server and used that token to request for creating port to Neutron server.
Finally, the Neutron Server decided that that's an authentication problem.
I'm sure that I requested to create instance using tenant 'demo''s info($OS_TENANT_NAME, $OS_USERNAME, $OS_PASSWORD, $OS_AUTH_URL were properly set with 'demo''s value) by
source demoopenrc.sh
with demo's credential in that file.
Is that something wrong in the Neutron client's configuration or booting process? I paste a part of the neutron.conf here:
the Keystone setting
[keystone_authtoken]
auth_uri = http://controller:5000
auth_host = controller
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = neutron
admin_password = neutronpass
signing_dir = $state_path/keystone-signing
Since the Neutron client used 'neutron' user's credential for token getting, is there something wrong in this part?
The problem has been solved after nearly a month. For anyone still interested in this problem, please visit here
I have devstack installed on a ubuntu 12.04 and I could get logged into Dashboard , Now I changed the IP of my ubuntu machine. After changing the IP, I couldn't log into Dashboard anymore
I gets the following error message. I can see my old IP in the error message.

Is there a documented procedure available to change the IP address manually ?
My New IP doesn't have connection to internet so I wouldn't be able to redeploy devstack
Thanks guys for your answers..
I missed to update my answer, I fixed that issue in an easy way.
Solution is first run unstack.sh and then run stack.sh once more. It will do the necessary fix. Since I haven't made much progress with Devstack after installation it makes me more confident to run stack.sh
For the second time when you run stack.sh its not needed to connect to internet, So my issue is fixed.
Feel free to share your thoughts on this.
You will need to change the IP address hard-coded in OpenStack configuration files generated by devstack. They are stored in /etc/ and elsewhere.
http://xmodulo.com/2013/04/how-to-change-ip-address-after-openstack-installation-via-devstack.html
Here's a few steps I've taken to get back online.
backup the answers file...
cp packstack-answers-20130417.txt packstack-answers.txt-SAVE
replace ip addresses...
sed -i '/s/10\.10\.248\.11/10\.32\.70\.10/g' packstack-answers-20130417.txt
Delete the cinder loopback devices, installer fails if it exists
losetup -d /dev/loop0
List what's left mounted via the loop.
losetup -a
rm /var/lib/cinder/cinder-volumes
Now rerun the deploy scripts
packstack --answer-file=packstack-answers-20130417.txt
Fix up other IP addressing concerns with nova-manage in the CLI.
Should work from here.
