Install and configure compute node¶
The compute node handles connectivity and security groups for instances.
Install the components¶
# apt install neutron-linuxbridge-agent
Configure the common component¶
The Networking common component configuration includes the authentication mechanism, message queue, and plug-in.
Note
Default configuration files vary by distribution. You might need
to add these sections and options rather than modifying existing
sections and options. Also, an ellipsis (...
) in the configuration
snippets indicates potential default configuration options that you
should retain.
Edit the
/etc/neutron/neutron.conf
file and complete the following actions:In the
[database]
section, comment out anyconnection
options because compute nodes do not directly access the database.In the
[DEFAULT]
section, configureRabbitMQ
message queue access:[DEFAULT] # ... transport_url = rabbit://openstack:RABBIT_PASS@controller
Replace
RABBIT_PASS
with the password you chose for theopenstack
account in RabbitMQ.In the
[DEFAULT]
and[keystone_authtoken]
sections, configure Identity service access:[DEFAULT] # ... auth_strategy = keystone [keystone_authtoken] # ... www_authenticate_uri = http://controller:5000 auth_url = http://controller:5000 memcached_servers = controller:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = neutron password = NEUTRON_PASS
Replace
NEUTRON_PASS
with the password you chose for theneutron
user in the Identity service.Note
Comment out or remove any other options in the
[keystone_authtoken]
section.
In the
[oslo_concurrency]
section, configure the lock path:[oslo_concurrency] # ... lock_path = /var/lib/neutron/tmp
Configure networking options¶
Choose the same networking option that you chose for the controller node to configure services specific to it. Afterwards, return here and proceed to Configure the Compute service to use the Networking service.
Configure the Compute service to use the Networking service¶
Edit the
/etc/nova/nova.conf
file and complete the following actions:In the
[neutron]
section, configure access parameters:[neutron] # ... auth_url = http://controller:5000 auth_type = password project_domain_name = default user_domain_name = default region_name = RegionOne project_name = service username = neutron password = NEUTRON_PASS
Replace
NEUTRON_PASS
with the password you chose for theneutron
user in the Identity service.See the compute service configuration guide for the full set of options including overriding the service catalog endpoint URL if necessary.
Finalize installation¶
Restart the Compute service:
# service nova-compute restart
Restart the Linux bridge agent:
# service neutron-linuxbridge-agent restart
