关于ansible，尝试执行脚本时被拒绝的权限

Question

我是newbee with ansible，所以我在尝试运行自己的playbook时遇到错误。

我的剧本失败，这个动作：

# run check-feed-adapter-folders script. the script tries to create some folders on HDFS. 
- command: "{{check_feed_adapter_folders_outputpath}}/check.sh" 

这是ansible-剧本命令的输出：

TASK: [command {{check_feed_adapter_folders_outputpath}}/check-feed.sh] ******* 
<127.0.0.1> REMOTE_MODULE command /var/app/check-feed-adapter-folders/check-feed.sh 
<127.0.0.1> EXEC ['/bin/sh', '-c', 'mkdir -p $HOME/.ansible/tmp/ansible-tmp-1423231416.19-167270274703096 && echo $HOME/.ansible/tmp/ansible-tmp-1423231416.19-167270274703096']

msg: [Errno 13] Permission denied 

FATAL: all hosts have already failed -- aborting 

这是奇怪的，因为如果我尝试手动运行该脚本，它完美作品

[root@dub-vcd-vms171 core2door.ansible]# sh /var/app/check-feed-adapter-folders/check-feed.sh  [INFO][CheckTopologyFolder][2015-02-06 14:05:32] CheckFeedFolder:41 - Started main method CheckTopologyFolder. param1: /var/app/feed-adapter/feed-adapter-SIP-Pub.properties

[WARN][CheckTopologyFolder][2015-02-06 14:05:33] NativeCodeLoader:62 - Unable to load native-hadoop library for your platform... using builtin-java classes where applicable 

如果我尝试通过shell更改命令，则出现同样的错误：

failed: [127.0.0.1] => {"changed": true, "cmd": "/var/app/check-feed-adapter-folders/check-feed.sh", "delta": "0:00:00.004738", "end": "2015-02-06 14:12:10.257034", "rc": 126, "start": "2015-02-06 14:12:10.252296", "warnings": []} 
stderr: /bin/sh: /var/app/check-feed-adapter-folders/check-feed.sh: Permission denied 

FATAL: all hosts have already failed -- aborting 

有人能帮助我吗？

如果您可以通过sh /.../check.sh运行命令并且命令模块内的运行不起作用（权限被拒绝），那么我认为该文件不可执行。

为了解决这一呼吁明确/bin/sh /.../check.sh在你的剧本：

# run check-feed-adapter-folders script. the script tries to create some folders on HDFS. 
- command: /bin/sh "{{check_feed_adapter_folders_outputpath}}/check.sh" 

Alternativly你可以检查你的脚本是否有在文件（#!/bin/sh）的开始家当线并使其executeable（chmod 755 /.../check.sh）。
