1.环境说明

系统：ubuntu16.04 LTS

openstack版本：queen

opendaylight版本：release/oxygen-sr3

2.集成步骤

（1）主机提前准备安装好git等基本配置

宿主机ip：192.168.0.10（eth0，只有一块网卡）

（2）pip源地址也换为国内的豆瓣源

安装pip

$ sudo apt-get install python-pip -y

创建pip配置文件&设置pip源：　

　 $ mkdir ~/.pip

　 $ vim ~/.pip/pip.conf

输入以下内容，没有配置文件可以创建：

[global]

index-url = http://pypi.douban.com/simple/

trusted-host = pypi.douban.com

（3）下载devstack

创建stack用户

$ sudo useradd -s /bin/bash -d /opt/stack -m stack

设置权限

$ echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack

下载源码

$ sudo su - stack

$ git clone https://git.openstack.org/openstack-dev/devstack -b stable/ocata

设置配置文件

$ cd devstack

$ vim local.conf

local.conf内容如下：

[[local|localrc]]

开始安装openstack和opendaylight，运行脚本

$ ./stack

3.验证环境

（1）检查Open vSwitch (virtual layer-2 switch)是否 正在被监听，通过ports 6640and6653端口：

$ sudo ovs-vsctl show | grep '6640\|6653'

（2）检查opendaylight进程正在执行“

$ ps aux | grep opendaylight

（3）检查OVS的配置和接口mapping

$ sudo ovs-vsctl get Open_vSwitch . other_config

输出结果：{local_ip="192.168.0.10", provider_mappings="public:veth-pub-int"}

（4）在neutron的配置文件中查看opendaylight是否是service plugin，path： /etc/neutron/neutron.conf.

$ grep -i odl /etc/neutron/neutron.conf

输出结果：service_plugins = odl-router_v2

（5）查看ml2 的配置文件是否有opendaylight的配置：

path：/etc/neutron/plugins/ml2/ml2_conf.ini

$ grep -i 'opend\|odl\|8087' /etc/neutron/plugins/ml2/ml2_conf.ini

（6）检查neutron-agent是否正常工作

$ neutron agent-list

（7）检查弄否登陆opendaylight命令行环境

$ /opt/stack/opendaylight/distribution-karaf-0.7.0-SNAPSHOT/bin/client

4.构建网络拓扑

（1）构建网络拓扑如下：

（2）查看ovs

$ sudo ovs-vsctl show

（3）查看br-int网桥上的openflow流表项

$ sudo ovs-ofctl --protocol=OpenFlow13 dump-flows br-int

（4）由配置文件或者通过以下命令，可知openstack外网的绑定的网桥是：provider_mappings="public:veth-pub-int"

由于本环境在devstack部署环境下，没有在veth-pub-int和物理网卡之间做地址转换，所以需要手动配置iptables nat规则：

$ sudo iptables -t nat -A POSTROUTING -s 172.24.5.0/24 -o eth0 -j MASQUERADE

PS：172.24.5.0/24：veth-pub-int 的IP地址，eth0为宿主机的物理网卡

（5）网络连接结构：

 

（6）验证虚拟机能够访问外网：

5.注意事项

（1）搭建过程应该不算难，主要是我在搭建过程中走了一些弯路，按照文档来搭建应该不会有问题。

（2）目前有个问题，就是odl现在没有web界面，正常情况下，是可以在ODL中看到拓扑的，但是因为我集成的配置文件，配置的是latest-snapshot，我问了这方面的老师，他说可能是因为这个版本没有将这个显示web feature放进去，可能是这个原因，所以我推荐换一个发布版的版本，如：latest-release。
