your auth_credentials are not mapping correctly to keystone commands.

for the first user better you set environmental variables like OS_SERVICE_TOKEN and OS_SERVICE_ENDPOINT by the following command.

openssl rand -hex 10  (this will produce a 10 digit key copy it) then type
export OS_SERVICE_TOKEN=10 digit key   
export OS_SERVICE_ENDPOINT=http://controller:35357/v2.0

if this works properly then for second time onwards you have to create admin-openrc.sh filef first. then execute the following command

keystone --os-username=admin --os-password=ADMIN_PASS --os-auth-url=http://controller:35357/v2.0 token-get

this returns a token with name and id generated randomly (don't panic output would be bigger than your screen) after that run the below command

keystone --os-username=admin --os-password=ADMIN_PASS --os-tenant-name=admin --os-auth-url=http://controller:35357/v2.0 \
token-get

now copy the credentials to your admin-openrc file

export OS_USERNAME=admin
export OS_PASSWORD=ADMIN_PASS
export OS_TENANT_NAME=admin
export OS_AUTH_URL=http://controller:35357/v2.0

just remember where you create this file its better to create it in /etc/keystone then source it by the command

source admin-openrc.sh

you have to source this everytime if you restart your system

yeah..i m usin juno .why would we need the openssl command. i tried all the commans but im getin the vfollowing error. ERROR (CommandError): Invalid OpenStack Nova credintials.

Queen ( 2015-01-23 03:37:16 -0500 )edit

why do we need token

Queen ( 2015-01-23 03:37:31 -0500 )edit

Thanks! This helped. I just downloaded the admin-openrc.sh from the panel and copied it to /etc/keystone. Do I have to copy this to every controller? and can I add a script to rc.local so it will source on boot?

image description This error comes when you are not authenticated. you can solve this error in two ways 1, source your creds admin file. which will be in the controller node. source creds admin Now I have attached screenshot PLEASE go through it.

2.open the creds-admin file and do export SERVICE_TOKEN=ADMIN export SERVICE_ENDPOINT="http://${HOST_IP}:35357/v2.0"

now you can execute any command prior to your congifuration.

Hope it resolves youur problem.

OpenStack uses keystone to do Authentication, the error indicate that you have not provided user credentials(username, password) as well as the keystone endpoint, you need to provide these information like this:

OS_REGION_NAME=RegionOne
OS_IDENTITY_API_VERSION=2.0
OS_USERNAME=admin
OS_PASSWORD=password
OS_AUTH_URL=http://192.185.180.100:5000/v2.0
OS_TENANT_NAME=admin

then execute the nova flavor-list.

Hope that helps!

hello queen. i guess your second question is VM creation. if the previous issues is resolved and all your services are up and running you can directly go for launch instance. from installation docs
