OpenStack 基金會的白金會員有Canonical(ubuntu),HP,IBM,Intel,RedHat,SUSE. 這是每年要交50萬美金的. (http://www.openstack.org/foundation/companies/)

台灣的雲端產業協會也是金牌會員之一.

看看這些會員名單, 就應該明白 OpenStack 將是他們未來產品的一環,我們大概就是使用者的角色了.

上個月VMware 發表新產品,就展示了如何在她的環境下建立OpenStack,也證明了這點.

去年至開始Trace OpenStack 程式時,花了一些時間來建立開發環境, 也作了些紀錄備忘.

以下就是環境設定的紀錄與指令說明:

要運行OpenStack 就要裝Linux.

我們先在Windows上用VMWare Player裝CentOS6.5.

下載keystone-2014.1.1 source code.

安裝openstck keystone.

再裝Eclipse.

主要是要在Eclipse來 Trace程式, 所以要安裝PyDev.

做過幾次每次都不太一樣, 所以要隨機應變, 見招拆招了.

重點就是把keystone的python dependencies裝全.

**2014901


-install the dependencies directly into your system from the requires files:

# Install the dependencies for running keystone
$ pip install -r requirements.txt

# Install the dependencies for developing, testing, and running keystone
$ pip install -r test-requirements.txt

# Use 'python setup.py' to link Keystone into Python's site-packages
$ python setup.py develop

(裝了以上開發設定後在正式環境就會有問題, 所以CentOS VM 要先備份.  正式環境就跳過這段)

-import keystone to eclipse PyDev

-install pastedeploy

[root@localhost markhsia]# pip install pastedeploy
