大概意思是：使用ssh測試以下是否能夠正常連接，要是可以的話就繼續，不可以的話就直接報錯了。之後，會用ssh命令在你指定的主機的/root/.ansible/tmp/這個下面穿件一堆臨時目錄並且從你的ansible的管理機的上面按照你的需求呢生成一個.py的文件(這塊怎麽生　　　　　　成的不太清楚反正和各種模塊有關系，得看源碼但我看不懂。。。)之後就會把這個.py的文件下發到你指定的主機上，怎麽下發呢？（要是不相信你可以寫一個shell腳本把這個.py文件抓出來看下裏面的代碼）

就是用sftp或者scp（這個可以在配置文件中指定）傳過去到/root/.ansible/tmp/這個下面的臨時目錄中，之後用ssh遠程執行命令/usr/bin/python .py文件，執行完成後再把所有的臨時目錄和.py文件刪除，這個ansible的管理過程就執行完成了。

解決上面的報錯：yum -y install openssh-clients
