Configuring Neutron to use Keystone

The Neutron configuration file found at /etc/neutron/neutron.conf has dozens of settings that can be modified to meet the needs of the OpenStack cloud administrator. A handful of these settings must be changed from their defaults as part of this installation.

To specify Keystone as the authentication method for Neutron, update the [DEFAULT] section of the Neutron configuration file on all hosts with the following setting:

[DEFAULT] 
... 
auth_strategy = keystone 

Neutron must also be configured with the appropriate Keystone authentication settings. The username and password for the neutron user in Keystone were set earlier in this chapter. Update the [keystone_authtoken] section of the Neutron configuration file on all hosts with the following settings:

[keystone_authtoken] 
... 
auth_uri = http://controller01:5000 
auth_url = http://controller01:35357 
memcached_servers = controller01:11211 
auth_type = password 
project_domain_name = default 

user_domain_name = default 
project_name = service 
username = neutron 
password = neutron
