ansible api实现命令异步执行

代码也可以在这里查看https://github.com/ivonlee/ansible/blob/master/ansible_api_async_run.py

tornado上实现ansible api异步执行，方便php写的运维后台调用，当然php后台还是要做一个类似于队列的东西，将任务存在redis或者mongodb里面，然后有个php进程持续监听任务队列。

下面的脚本运行后，可以用类似POSTMAN工具进行post数据测试，如果你的平台本来就是python的，那更方便了，自己写个简陋的web界面，直接执行了，不用tornado做web容器了。

mongodb里面的表信息，ansible_task是收到的任务，ansible_job里面有任务执行结果

上代码，python比较搓，求大牛带我
