基於CentOS 6.8的OpenStack手動安裝-環境配置
1 環境
1.1 主機網路
1.1.1 系統的架構
1）節點分為控制節點、計算節點、塊儲存節點、物件儲存節點
2）所有管理網路(10.168.0.0/24)和虛擬網路都使用私網地址連線共有網路（網際網路203.0.113.x/8）
3）物理網路與虛擬網路(非10.168.0.0/24段)應當處於不同的網段
4）本架構NAT中的閘道器地址為10.168.0.1
5）物理節點使用NAT保持時間同步
1.1.2 部署資訊
1)控制節點
hostname=rodm.cmdschool.org
ip address=10.168.0.125
OS=CentOS 6.8
2)計算節點
hostname=rod0[1-2].cmdschool.org
ip address=10.168.0.[126-127]
OS=CentOS 6.8
1.1.3 名稱服務（可選）
vim/etc/hosts
輸入如下資訊：
10.168.0.125rodm.cmdschool.org 10.168.0.126rod01.cmdschool.org 10.168.0.127rod02.cmdschool.org
