Install and configure compute node¶

Install the components¶

# yum install openstack-neutron-linuxbridge ebtables ipset

Configure the common component¶

The Networking common component configuration includes the authentication mechanism, message queue, and plug-in.

• Edit the /etc/neutron/neutron.conf file and complete the following actions:

  • In the [database] section, comment out any connection options because compute nodes do not directly access the database.

  • In the [DEFAULT] section, configure RabbitMQ message queue access:

    [DEFAULT]
    # ...
    transport_url = rabbit://openstack:RABBIT_PASS@controller
    

    Replace RABBIT_PASS with the password you chose for the openstack 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 the neutron 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]
    # ...
    url = http://controller:9696
    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 the neutron user in the Identity service.

Finalize installation¶

1. Restart the Compute service:

   # systemctl restart openstack-nova-compute.service
   

2. Start the Linux bridge agent and configure it to start when the system boots:

   # systemctl enable neutron-linuxbridge-agent.service
   # systemctl start neutron-linuxbridge-agent.service
