OpenStack stein安裝（十）install neutron on compute

1. Install the components

   # yum install openstack-neutron-linuxbridge ebtables ipset

2. 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:openstack123@dbs.flex.net

○ In the [DEFAULT] and [keystone_authtoken] sections, configure Identity service access:
    [DEFAULT]
    # ...
    auth_strategy = keystone

    [keystone_authtoken]
    # ...
    www_authenticate_uri = http://stack.flex.net:5000
    auth_url = http://stack.flex.net:5000
    memcached_servers = dbs.flex.net:11211
    auth_type = password
    project_domain_name = default
    user_domain_name = default
    project_name = service
    username = neutron
    password = neutron123
    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

3. Configure networking options

   選擇下列網絡選項中的一個，或兩個全選，參看下面的兩個章節。並返回這裏再向下繼續配置.
   ○ Networking Option 1: Provider networks
   ○ Networking Option 2: Self-service networks

4. 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://stack.flex.net:9696
   auth_url = http://stack.flex.net:5000
   auth_type = password
   project_domain_name = default
   user_domain_name = default
   region_name = RegionOne
   project_name = service
   username = neutron
   password = neutron123

5. Finalize installation

   ○ 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
