建议三种网络选择 GRE

注意：接与上一篇博客内容进行更新
由于整个开源openstack安装过程过于繁琐，命令太长，太繁琐，于是把整个安装命令写成shell脚本。

脚本数量内容过多，已经推送自我的github源码托管中心了。
这是本篇脚本内容所在的github仓库位置
Flat网络脚本
controller节点 compute 节点

GRE网络脚本
controller节点 compute 节点

VLAN网络脚本文件
controller节点 compute 节点

[root@controller centos]# cd /usr/local/bin/这是所有需要的脚本的整个路径

5.2通过脚本创建neutron网络
5.15网络服务的操作命令已经编写成shell脚本，通过脚本进行一键安装。如下：

创建flat网络
#Controller节点
执行脚本iaas-install-neutron-controller-flat.sh进行安装
#Compute节点
执行脚本iaas-install-neutron-compute-flat.sh进行安装

创建gre网络
#Controller节点
执行脚本iaas-install-neutron-controller-gre.sh进行安装
#Compute节点
执行脚本iaas-install-neutron-compute-gre.sh进行安装

创建vlan网络
#Controller节点
执行脚本iaas-install-neutron-controller-vlan.sh进行安装
#Compute节点
执行脚本iaas-install-neutron-compute-vlan.sh进行安装

下面是本篇内容的命令的详细操作过程（脚本中已经包含该篇命令的所有操作，但是建议还是熟悉下整个过程之后再运行脚本）

5.15 选择Neutron网络模式
以下任意选择一种方式进行安装
