运维离不开自动化,python的发展更是给自动化注入了一剂兴奋剂;还记得当时公司年会,大家都在嗨皮,苦逼的运维攻城狮还在卖力的给一个大客户手动开通500台云主机的情形,现在想想好傻O(∩_∩)O哈哈~。如果早点接触pyVmomi,就不至于这么苦逼了。
pyVmomi is the Python SDK for the VMware vSphere API that allows you to manage ESX, ESXi, and vCenter.官方如是说。自己这里写篇博客整理一下,也希望对还停留在手工时代的同学有所帮助。
坏境配置:
1、网络环境:
安装pyvmomi的server和VMware vCenter 网络打通;
2、系统环境:
pyvmomi用pip安装,所以需要有python和pip;pyvmomi 6.0.0需要的python版本支持为2.7, 3.3 和 3.4, 支持的vSphere 版本为:6.0, 5.5, 5.1 和 5.0。
安装如下:
1

|
$ sudo apt-get install python-pip
$ sudo pip install pyvmomi
$ sudo pip freeze | grep pyvmomi #查看安装的pyvmomi版本,现在是6.0版本
pyvmomi==6.0.0 #如果已经安装过,升级用pip install --upgrade pyvmomi
|
或者也可以下载源码包安装,https://github.com/vmware/pyvmomi.git:
1
|
$ sudo python setup.py install
|
3、pyvmomi提供了一些社区样本项目,可以参考编写自己的代码:
1
|
git clone https: //github .com /vmware/pyvmomi-community-samples .git
