Hi all --

I'm trying to set up keystone and while create the admin tenant, I get this error :

An unexpected error prevented the server from fulfilling your request. (HTTP 500)

Looking at logs I see :

OperationalError: (OperationalError) (1045, "Access denied for user 'keystone'@'allinone' (using password: YES)") None None

I created the keystone database and users as directed and gave privileges to keystone user on %, localhost and allinone.

What else needs to be done for this ?

Mysql is complaining. Check the database credentials you're passing to it.

import os

from keystone.server import wsgi as wsgi_server

name = os.path.basename(__file__)

# NOTE(ldbragst): 'application' is required in this context by WSGI spec.

# The following is a reference to Python Paste Deploy documentation


application = wsgi_server.initialize_application(name)

If this not there keystone will not import db

I navigated between many forums to figure out the answer and I found out a good solution, which is working for me:

Instead of typing the command: # su -s /bin/sh -c "keystone-manage db_sync" keystone, you must type only: /bin/sh -c "keystone-manage db_sync" keystone

The issue came that: if you have already loggin as a root so you haven't needed anymore to use the "su -s" command at the beginning.

After that, you can execute the command: openstack service create --name keystone ==description "OpenStack Identity" identity, which will work perfectly fine.

This answer worked for me when following the latest Liberty documentation. I didn't have to change any db passwords or whatnot. This should be the accepted answer.

I have struggled with the same issue, but none of them seem to work. I am trying to install liberty on centos 7. Have changed the /etc/keystone/keystone.conf "connection = mysql://keystone:keystone123@localhost/keystone" had controller earlier instead of localhost. None of these seem to work

Thank you, this has worked for me, installation guide is a bit inconsistent as most commands are as root, so you naturally put that in as root as well
