快速搭建本地私有儲存雲, 使用Raspberry Pi 2安裝OpenStack DevStack



0. 我的環境是Mac OS X 10.10
1.
- 使用Ubuntu 14.04 LTS image for Raspberry Pi 2 https://wiki.ubuntu.com/ARM/RaspberryPi
- Download image and unzip to Mac desktop
- use diskutil list 找到你的SD card 例如是/dev/disk1
- sudo diskutil umountDisk /dev/disk1
- sudo dd bs=1m if=~/Desktop/Pi\ 2\ image/2015-04-06-ubuntu-trusty/2015-04-06-ubuntu-trusty.img of=/dev/disk1
- 用這張SD card 幫Raspberry Pi 2開機

2.
- 登入Raspberry pi, 預設是沒有openssh server, 請先外接HDMI螢幕和USB鍵盤登入.
- sudo apt-get install openssh-server

3. 開始安裝Openstack
- sudo apt-get -y update
- sudo apt-get -y install git vim
- git clone https://github.com/openstack-dev/devstack.git -b stable/icehouse devstack/
- sudo devstack/tools/create-stack-user.sh
- sudo su stack
- cd
- git clone https://github.com/openstack-dev/devstack.git -b stable/icehouse devstack/
- sudo chown -R stack:stack /opt/stack
- cd devstack/
- vim local.conf # copy in the contents of the one below. 私有儲存雲只需要帳號(keystone)與儲存(swift)部分, 因此簡化local.conf如下:

[[local|localrc]]

# Credentials
DATABASE_PASSWORD=devstack
ADMIN_PASSWORD=devstack
SERVICE_PASSWORD=devstack
SERVICE_TOKEN=devstack
RABBIT_PASSWORD=devstack

# Services
ENABLED_SERVICES=mysql,key
ENABLED_SERVICES+=,s-proxy,s-object,s-container,s-account

# Branches
KEYSTONE_BRANCH=stable/icehouse
NOVA_BRANCH=stable/icehouse
NEUTRON_BRANCH=stable/icehouse
SWIFT_BRANCH=stable/icehouse
GLANCE_BRANCH=stable/icehouse
CINDER_BRANCH=stable/icehouse
HEAT_BRANCH=stable/icehouse
TROVE_BRANCH=stable/icehouse
HORIZON_BRANCH=stable/icehouse

# Swift Configuration
SWIFT_REPLICAS=1
SWIFT_HASH=66a3d6b56c1f479c8b4e70ab5c2000f5

# Enable Logging
LOGFILE=/opt/stack/logs/stack.sh.log
VERBOSE=True
LOG_COLOR=True
SCREEN_LOGDIR=/opt/stack/logs


# 啟動OpenStack相關服務, 使用./stack
# 如果需要將OpenStack服務停止,使用./unstack

Test the Authentication from Keystone, 請注意單雙引號要正確.
$curl -d '{"auth":{"passwordCredentials":{"username":"demo","password":"devstack"},"tenantName":"demo"}}' -H "Content-type: application/json" http://localhost:5000/v2.0/tokens

可以得到關於整個服務的相關資訊, 例如是, 最重要的就是swift的publicURL以及Region (預設Region名稱是RegionOne):
之後在使用Openstack SDK的時候就需要這些資訊.

到這裡我們已經完成一個利用OpenStack快速搭建一個本地私有儲存雲的過程, Swift服務網址如下：
http://192.168.10.170:8080/v1/AUTH_9fa3258c21744af99682681f636ea831
username:demo
password:devstack
region:RegionOne
tenantName:demo
這些參數都是使用OpenStack SDK需要的部份.

你可以安裝python-swiftclient來進行簡單操作
>sudo pip install python-swiftclient
使用swift cli之前, 需要export一些環境變數
export OS_AUTH_URL=http://192.168.10.170:35357/v2.0
export OS_USERNAME=demo
export OS_TENANT_NAME=demo
export OS_PASSWORD=devstack

>swift stat
>swift list #列出目前有的container
>swift post abc #產生一個container named abc
