Openstack网络服务Neutron主要负责网络连接任务，包括租户网络及子网的创建、网卡端口配置、访问IP地址管理以及高级网络服务（负载均衡DBaas、防火墙FwaaS）功能。以上功能通过不同的插件和代理来实现二层、三层及四七层网络虚拟化，常见的代理L3(3层)，DHCP(动态主机IP地址)，以及插件代理，插件式的实现可以容纳不同的网络设备和软件，为OpenStack架构与部署提供了灵活性。
Neutron的组成如下：
为了减轻网络的负载，网络服务在单独节点上（三个网络节点上）进行部署，但为了方便Neutron API的统一管理与调用，Neutron Server是部署在控制节点上，即Neutron需要在控制节点上配置neutron的管理和ml2插件配置，需要在网络节点上配置neutron-openvswitch-agent、 neutron-l3-agent、neutron-dhcp-agent和neutron-metadata-agent服务，以及创建外网访问br-ex网桥配置。网络服务架构，计算节点上安装配置neutron-openvswitch-agent和openvswitch服务，服务架构同下图类似：
此外，由于本部署采用了HA高可用架构，同三个控制节点上管理集群类似，在三个网络节点同样安装了pacemaker集群管理软件，用于网络节点上neutron-openvswitch-agent、 neutron-l3-agent、neutron-dhcp-agent和neutron-metadata-agent服务的高可用配置。
首先在控制节点上通过0-set-config.sh设置网络节点配置信息：
| 1 2 3 4 5 | declare -A networker_map=(["network01"]="192.168.2.14" ["network02"]="192.168.2.15" ["network03"]="192.168.2.16"); ### 网络HA集群默认部署节点（必须存在该主机名的节点） network_host=network01 ### 网络节点是否单独部署，若是设置为yes，否设置为no networker_split=yes |
然后执行安装脚本install-configure-neutron.sh，会完成neutron的所有配置安装，install-configure-neutron.sh在完成控制节点上配置，会调用 install-configure-pacemaker-networkers.sh脚本进行网络节点HA集群部署，然后调用install-configure-neutron-networkers.sh完成网络节点上服务配置及br-ex外网网桥创建及配置。
PS. 网络节点单独部署优势不仅可以减少虚拟机访问的网络负载，还可以将Openstack控制集群与网络集群隔离开，如果控制集群发生异常，不影响网络集群，此时已经创建的虚拟机可以正常访问，不影响其中运行业务，这一点可以大大减少故障范围，也可以方便进行故障恢复。
此情景不需要构建网络节点高可用集群，直接在控制节点上安装所有网络服务，将所有网络服务加入到控制节点上pacemaker资源中即可。
首先在控制节点上通过0-set-config.sh设置网络节点配置信息：让网络节点和控制节点重叠即可，并设置网络节点单独部署配置项为no
| 1 2 3 4 5 | declare -A networker_map=(["controller01"]="192.168.2.11" ["controller02"]="192.168.2.12" ["controller03"]="192.168.2.13"); ### 网络HA集群默认部署节点（必须存在该主机名的节点） network_host=controller01 ### 网络节点是否单独部署，若是设置为yes，否设置为no networker_split=no |
然后执行install-configure-neutron.sh安装即可，实际安装过程中，会跳过 install-configure-pacemaker-networkers.sh脚本，不会创建网络节点的高可用集群，由于网络节点和控制节点融合，所有的网络服务都会加入到控制节点pacemaker上资源中。
