Question

我是ansible的新手，所以我在尝试运行自己的剧本时遇到错误。

我的剧本因此动作失败：

# 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-playbook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

这很奇怪，因为如果我尝试手动运行脚本，它可以完美地运行

[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
[INFO][CheckTopologyFolder][2015-02-06 14:05:32] CheckFeedFolder:47 - Trying to create the folder on HDFS

[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，则会出现同样的错误：

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中的运行不起作用（权限被拒绝），那么我认为该文件不可执行。

要在剧本中明确解决此问题/bin/sh /.../check.sh：

# 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"

另外，你可以检查你的脚本是否在文件的开头（#!/bin/sh）有一个shebang行，并使其可执行（chmod 755 /.../check.sh）。

关于ansible，在尝试执行脚本时权限被拒绝
