tornado实现ansible api web请求

这两天在写运维平台中的ansible命令执行功能，运维平台是php的，尝试了php的exec ?system?passthru?popen等函数，ansible 里面host ssh认证改为www，apache运行用户也为www，各种尝试，最后执行结果返回为空数组，执行 ssh www@192.168.3.169 ‘df -h’这种命令也是成功的，只是执行ansible命令不行，ansible-doc也可以。

<?PHP$cmd="/usr/bin/ansible 192.168.3.169 -m setup";exec($cmd,$result,$Errorcore);var_dump($result);?>

后来想想就换种方式吧，正好ansible-api是python的，就用tornado做个接口，然后php去调用接口执行命令
