Matthew Kassawara 117606139c Install: Neutron updates for Mitaka

Update neutron content for Mitaka.

1) Change 'public' to 'provider' and 'private' to
   'self-service' to improve distinction between these
   networks using neutronish terms.
2) Remove explicit installation of some packages due to
   dependency fixes.
3) Remove explicit configuration of verbosity.
4) Remove explicit configuration of ARP spoofing protection.
5) Remove extraneous configuration for the metadata agent.
6) Remove extraneous configuration for nova-neutron
   interaction.
7) Reduce discussion of MTU because Mitaka fixes most
   of the issues, but we still need to explain the
   most limitation of overlay networks.
8) Generally improve wording.

Install and configure compute node

The compute node handles connectivity and security groups <security group> for instances.

ubuntu or rdo or obs

Install the components

ubuntu

# apt-get install neutron-plugin-linuxbridge-agent conntrack

rdo

# yum install openstack-neutron-linuxbridge ebtables

obs

# zypper install --no-recommends openstack-neutron-linuxbridge-agent

debian

Install and configure the Networking components

# apt-get install neutron-plugin-linuxbridge-agent

Respond to prompts for database management, Identity service credentials, service endpoint, and message queue credentials.
Select the ML2 plug-in:

Note

Selecting the ML2 plug-in also populates the service_plugins and allow_overlapping_ips options in the /etc/neutron/neutron.conf file with the appropriate values.

ubuntu or rdo or obs

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] and [oslo_messaging_rabbit] sections, configure RabbitMQ message queue access:
```
[DEFAULT]
...
rpc_backend = rabbit

[oslo_messaging_rabbit]
...
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS
```
  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]
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_id = default
user_domain_id = 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.
rdo
- 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 neutron-compute-compute.

neutron-compute-install-option1.rst neutron-compute-install-option2.rst

Configure Compute to use Networking

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:35357
auth_type = password
project_domain_id = default
user_domain_id = 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

rdo

Restart the Compute service:

# systemctl restart openstack-nova-compute.service

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

obs

The Networking service initialization scripts expect the variable NEUTRON_PLUGIN_CONF in the /etc/sysconfig/neutron file to reference the ML2 plug-in configuration file. Edit the /etc/sysconfig/neutron file and add the following:
```
NEUTRON_PLUGIN_CONF="/etc/neutron/plugins/ml2/ml2_conf.ini"
```

Restart the Compute service:

# systemctl restart openstack-nova-compute.service

Start the Linux Bridge agent and configure it to start when the system boots:

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

ubuntu or debian

Restart the Compute service:
```
# service nova-compute restart
```

Restart the Linux bridge agent:

# service neutron-plugin-linuxbridge-agent restart
