pyvmomi 实现VMware自动化

523rwfe

  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 2 3 4

$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

4、下面是 pyvmomi给出的获取所有vm的脚本：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119

5、执行之后输出格式如下：
