學習openstack 安裝實驗環境，經過諸多挫折，順利搭建，記錄如下，以作備忘。

環境： linux ubuntu16.04.3 , 虛擬機器上安裝，openstack是由devstack安裝 版本stable/pike

兩主機，一個是controller控制節點，安裝所有元件，另一臺是compute1計算節點

控制主機三個虛擬網路卡，計算主機兩個虛擬網路卡

首先兩臺電腦安裝 ubuntu16.04.3 server版，controller第一網路卡設定靜態ip：192.168.0.102, 計算節點compute第一個網路卡ip：192.168.0.103，安裝openssh 並設定允許root遠端登入

分別在兩臺主機開始安裝以下步驟：

1.修改apt為國內源

vi /etc/apt/sources.list

deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse

2.更新源

apt update

3.取得devstack程式碼

git clone http://git.trystack.cn/openstack-dev/devstack -b stable/pike

4.建立stack使用者

devstack/tools/create-stack-user.sh

5.移動目錄

mv devstack /opt/stack

chown -R stack:stack /opt/stack/devstack

6.切換到 stack 使用者

su – stack

cd devstack

7.編輯local.conf
在 /opt/stack/devstack 目錄下，建立 local.conf，控制節和計算節點分別如下

————–controller節點———————-

—————compute node common section

ENABLED_SERVICES=n-cpu,q-agt,n-api-meta,placement-client,n-novnc
NOVA_VNC_ENABLED=True
NOVNCPROXY_URL=”http://$SERVICE_HOST:6080/vnc_auto.html”

—————compute node special section

HOST_IP=192.168.1.103
FLAT_INTERFACE=ens33
VNCSERVER_PROXYCLIENT_ADDRESS=$HOST_IP
VNCSERVER_LISTEN=$HOST_IP

ENABLED_SERVICES+=,c-vol

8.執行安裝指令碼

./stack.sh

如果中途退出 可以再次執行
也可以執行 ./unstack.sh ./clean.sh清理後重新再執行./stack.sh 直至安裝成功
