openstack compute (nova) "error"
I'm trying to install OpenStack compute (nova) .. when I run command **nova list**
then out the results ERROR: You must provide a username via either --os_username or env[OS_USERNAME]
how to code a solution for me?
Answer
If you used devstack (http://devstack.org/) to deploy OpenStack you can use openrc trick:
$cd devstack/
$source openrc admin admin # for admin rights
or
$source openrc demo demo # for demo user
Otherwise you need to export OS variables manually:
$export OS_USERNAME = admin
$export OS_TENANT_NAME = <yourtenant>
$export OS_PASSWORD = <yourpasswd> # password which you used during deployment etc

If you want manually install all the services here's handy manual https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst
I'd recommend to install it once by this manual to learn how it works, and then use latest stable devstack each time when you need to set up a new environment just to save your time.
