devstack setup record

原因：

      看IBM的cloudman博客【天天5分鐘玩轉Openstack】學習的時候，有用到devstack，之前也看到devstack，遂想本身也踩踩坑裝一個。

      天天5分鐘玩轉Openstack地址：  https://www.ibm.com/developerworks/community/blogs/132cfa78-44b0-4376-85d0-d3096cd30d3f?lang=zh （2017/07/27 記錄）

 

開始：

      找到官方文檔 https://docs.openstack.org/developer/devstack/

      看到：If you do not have a preference, Ubuntu 16.04 is the most tested, and will probably go the smoothest.

      因此從裝 Ubuntu 16.04 開始。

 

動手：

   1.安裝系統：

      1. 下載ubuntu的桌面系統： https://www.ubuntu.com/download/desktop

      2. 下載好的鏡像刻到U盤中： 用UltraISO【啓動】->寫入硬盤映像 #菜單的第三個，而後第4個。

      3. U盤啓動後開始按步驟安裝完畢。

   2.設置系統：

      1. 系統裝好後發現ssh不了，坑爹的發現竟然默認不裝openssh-server，理解不了，跟公司申請了外網的代理以後。發現 set http_proxy=10.167.129.21:8080的方式不行。

      2. 參照其餘的解決方案，直接設置到 /etc/apt/apt.conf ， 內容以下：

Acquire::http::proxy "http://10.167.129.21:8080/";
Acquire::ftp::proxy "ftp://10.167.129.21:8080/";
Acquire::https::proxy "https://10.167.129.21:8080/";

      3. pip 的安裝的時候使用代理的方式爲： sudo pip install --upgrade pip --proxy=10.167.129.21:8080

      4. 設置了下源爲阿里雲的，直接修改 /etc/apt/sources.list ， 內容以下：

# deb cdrom:[Ubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1)]/ xenial main restricted
deb-src http://archive.ubuntu.com/ubuntu xenial main restricted #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted

deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe
deb http://mirrors.aliyun.com/ubuntu/ xenial multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse #Added by software-properties
deb http://archive.canonical.com/ubuntu xenial partner
deb-src http://archive.canonical.com/ubuntu xenial partner
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-security multiverse

      5. 更新系統源並更新系統 ：

sudo apt-get update
sudo apt-get upgrade 

    3.環境準備：

      1. git工具安裝。（devstack須要用到）

apt-get install git

      2. pip源的設置。（devstack須要用到）

stack@Jump-DevStack:~$ cat .pip/pip.conf

[global]
trusted-host=mirrors.aliyun.com
index-url=http://mirrors.aliyun.com/pypi/simple

    4.開始安裝：

      1. stack用戶做成。（devstack須要通常用戶執行）

sudo useradd -s /bin/bash -d /opt/stack -m stack
echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack
sudo su - stack

      2.下載devstack

git clone https://git.openstack.org/openstack-dev/devstack
cd devstack

      3. 建立local.conf文件，拷貝sample文件/opt/stack/devstack/samples/local.conf 到 /opt/stack/devstack/local.conf，進行修改，我修改的地方以下：

ADMIN_PASSWORD=admin1234
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
HOST_IP=193.168.140.127   #本機地址，這個是須要提早改好的

GIT_BASE=http://git.trystack.cn  #後面這三個是國內的openstack的源的地址，國外的下載實在太慢了。
NOVNC_REPO=http://git.trystack.cn/kanaka/noVNC.git
SPICE_REPO=http://git.trystack.cn/git/spice/spice-html5.git

你能夠提早下載好全部的openstack源碼,分別須要如下：  #能夠直接去官網git clone xxxxx.git的方式弄到本地例如： git clone git://git.openstack.org/openstack/heat.git
nova glance cinder horizon keystone neutron swift heat ceilometer tempest

      3. 最後一部開始安裝，官網的給出15-20分鐘，我只能呵呵：

./stack.sh

 

    5.我遇到的問題及解決：

      1.錯誤： generate-subunit: command not found

         #緣由缺乏相關包

         #解決方法：安裝相關包，以下

sudo apt-get install python-pip
sudo pip install --upgrade pip
sudo pip install -U os-testr

 

      2.錯誤消息以下：
