Openstack架构构建及详解(5)--Neutron组件(1)
5、验证
[root@controller ~]# source admin-openrc.sh
列出加载的扩展模块，确认成功启动neutron-server进程。
[root@controller ~]# neutron ext-list

2、配置neutron节点
1、编辑/etc/sysctl.conf文件，包含下列参数：
net.ipv4.ip_forward=1
net.ipv4.conf.all.rp_filter=0
net.ipv4.conf.default.rp_filter=0
[root@network ~]# sysctl -p
net.ipv4.ip_forward = 1
net.ipv4.conf.all.rp_filter = 0
net.ipv4.conf.default.rp_filter = 0
安装网络组件
yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch
编辑/etc/neutron/neutron.conf文件并完成下列操作：
a.编辑[database]小节，注释任何connection选项。因为network节点不能直接连接数据库。
b.编辑[DEFAULT]小节，配置RabbitMQ消息队列访问
[DEFAULT]
…
rpc_backend=rabbit
rabbit_host= controller.nice.com
rabbit_password= RABBIT_PASS
c.编辑[DEFAULT]和[keystone_authtoken]小节，配置认证服务访问：
[DEFAULT]
…
auth_strategy= keystone
[keystone_authtoken]
…
auth_uri= http://controller.nice.com:5000/v2.0
identity_uri= http://controller.nice.com:35357admin_tenant_name= service
admin_user= neutron
admin_password= NEUTRON_PASS
d.编辑[DEFAULT]小节，启用Modular Layer2(ML2)插件,路由服务和重叠IP地址功能：
[DEFAULT]
…
core_plugin
