  OpenStack网络(neutron)允许您创建并将其他OpenStack服务管理的接口设备附加到网络上。可以实现插件来适应不同的网络设备和软件,从而为OpenStack体系结构和部署提供灵活性。
  它包括以下组成部分:

Configure the metadata agent

The metadata agent provides configuration information such as credentials to instances.
Edit the /etc/neutron/metadata_agent.ini file and complete the following actions:

    ○ In the [DEFAULT] section, configure the metadata host and shared secret:
        [DEFAULT]
        # ...
        nova_metadata_host = stack.flex.net
        metadata_proxy_shared_secret = 1234 

        Replace METADATA_SECRET with a suitable secret for the metadata proxy.
Configure the Compute service to use the Networking service

Note: The Nova compute service must be installed to complete this step.
Edit the /etc/nova/nova.conf file and perform the following actions:

    ○ In the [neutron] section, configure access parameters, enable the metadata proxy, and configure the secret:
        [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
        service_metadata_proxy = true
        metadata_proxy_shared_secret = 1234
Finalize installation
  1. The Networking service initialization scripts expect a symbolic link /etc/neutron/plugin.ini pointing to the ML2 plug-in configuration file, /etc/neutron/plugins/ml2/ml2_conf.ini. If this symbolic link does not exist, create it using the following command:
    # ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
  2. Populate the database:
    # su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf \
      --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron
    注意:由于脚本需要完整的服务器和插件配置文件,数据库填充将在稍后用于网络。 
  3. Restart the Compute API service:
    # systemctl restart openstack-nova-api.service
  4. Start the Networking services and configure them to start when the system boots.
For both networking options:
    # systemctl enable neutron-server.service \
      neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
      neutron-metadata-agent.service
    # systemctl start neutron-server.service \
      neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
      neutron-metadata-agent.service

For networking option 2, also enable and start the layer-3 service:
    # systemctl enable neutron-l3-agent.service
    # systemctl start neutron-l3-agent.service
