I have installed openstack having one controller and 2 compute nodes on centos 7. After successful installation of openstack when i open dashboard it shows the following errors:

Error: Unauthorized: Unable to retrieve network quota information. Error: Unauthorized: Unable to retrieve networks. Error: Unauthorized: Unable to retrieve list of security groups

How do i resolve these ?

Verify that the services are running. Go to the CLI on the controller node, check the status of neutron,nova, keystone, and glance. Depending on you distro some tools to use are

# openstack-status# openstack-service status

or just look at the individual services.

That's correct

# source keystonerc_admin
# openstack-status
# systemctl | grep openstack
# systemctl | grep neutron

Check your logs, auth is done through keystone (/var/log/keystone/keystone.log) Neutron is /var/log/neutron/server.log and horizon is /var/log/horizon/horizon.log THey may be able to get give a better reason

You need ssh trusting relationships between nodes.
