echo 'net.bridge.bridge-nf-call-ip6tables=1' >> /etc/sysctl.conf
modprobe br_netfilter #表示向内核加入参数

openstack-config --set /etc/neutron/dhcp_agent.ini DEFAULT interface_driver linuxbridge
openstack-config --set /etc/neutron/dhcp_agent.ini DEFAULT dhcp_driver neutron.agent.linux.dhcp.Dnsmasq

openstack-config --set /etc/nova/nova.conf neutron metadata_proxy_shared_secret METADATA_SECRET
● 创建ML2插件文件符号连接
● 网络服务初始化脚本需要/etc/neutron/plugin.ini指向ML2插件配置文件的符号链接
ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
● 初始化数据库
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
● 重启计算节点nova-api服务
systemctl restart openstack-nova-api.service
● 开启neutron服务、设置开机自启动
[root@ct ~]# systemctl enable neutron-server.service \
neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
neutron-metadata-agent.service
[root@ct ~]# systemctl start neutron-server.service \

#ipset：iptables的扩展，允许匹配规则的集合而不仅仅是一个IP

physical_interface_mappings = provider:eth1
● 直接将node节点external网络绑定在当前节点的指定的物理网卡，不需要node节点配置网络名称，node节点只需要接收controller节点指令即可；controller节点上配置的external网络名称是针对整个openstack环境生效的，所以指定external网络绑定在当前node节点的eth0物理网卡上(也可能是bind0或br0)
[vxlan]
enable_vxlan = true #开启Vxlan网络
local_ip = 192.168.100.12

● 修改内核
echo 'net.bridge.bridge-nf-call-iptables=1' >> /etc/sysctl.conf #允许虚拟机的数据通过物理机出去
echo 'net.bridge.bridge-nf-call-ip6tables=1' >> /etc/sysctl.conf
modprobe br_netfilter #modprobe：用于向内核中加载模块或者从内核中移除模块。modprobe -r 表示移除

小结
三个节点都需要配置neutron网络，以下为部署思路：
配置neutron组件的用户、认证、endpoint
设置提供者provider网络（这里是桥接模式）
① 配置二层网络
② 配置网桥（插件）
③ 优化内核
④ 配置网桥接口与外部对接
⑤ 修改DHCP配置（修改配置文件、代理）
⑥ 配置网桥与内部组件的配置（修改配置文件、代理）
设置neutron与nova对接的配置
其中C1、C2节点配置相同
