Configuring Keystone

Hello people!! I’m am having this problem configuring keystone. I’m trying to create a tenant for an administrative user and a tenant for other openstack services:

$ keystone tenant-create --name=admin --description=“Admin Tenant”
$ keystone tenant-create --name=service --description=“Service Tenant”

I get the following error:
Unable to establish connection to controller:35357/v2.0/tenants

Please help me solving this error!!

1 - Check whether keystone service is running.
2 - Check log files at /var/log/keystone/keystone.log
3 - This could very well be an authentication issue too, so ensure the right credentials are used. Source the file with the correct credentials. Depending on whether UUID or PKI was used, I would start at the link below for troubleshooting:
