運維離不開自動化,python的發展更是給自動化注入了一劑興奮劑;還記得當時公司年會,你們都在嗨皮,苦逼的運維攻城獅還在賣力的給一個大客戶手動開通500臺雲主機的情形,如今想一想好傻O(∩_∩)O哈哈~。若是早點接觸pyVmomi,就不至於這麼苦逼了。python
pyVmomi is the Python SDK for the VMware vSphere API that allows you to manage ESX, ESXi, and vCenter.官方如是說。本身這裏寫篇博客整理一下,也但願對還停留在手工時代的同窗有所幫助。git
壞境配置:github
一、網絡環境:express
安裝pyvmomi的server和VMware vCenter 網絡打通;apache
二、系統環境:bash
pyvmomi用pip安裝,因此須要有python和pip;pyvmomi 6.0.0須要的python版本支持爲2.7, 3.3 和 3.4, 支持的vSphere 版本爲:6.0, 5.5, 5.1 和 5.0。網絡
安裝以下:app
$sudo apt-get install python-pip $sudo pip install pyvmomi $sudo pip freeze | grep pyvmomi #查看安裝的pyvmomi版本,如今是6.0版本 pyvmomi==6.0.0 #若是已經安裝過,升級用pip install --upgrade pyvmomi
或者也能夠下載源碼包安裝,https://github.com/vmware/pyvmomi.git:less
$sudo python setup.py install
三、pyvmomi提供了一些社區樣本項目,能夠參考編寫本身的代碼:運維
git clone https://github.com/vmware/pyvmomi-community-samples.git
四、下面是 pyvmomi給出的獲取全部vm的腳本:
