在 anisble 上运行 python 脚本

我有一个 ansible 服务器，我发现它运行良好，但是当我尝试在部署的服务器上运行 python 脚本时，我得到了no such file or directory，即使我直观地确认它们在那里。

这是我的 anisble 剧本代码：

create a user directory and a dev subdirectory
- name: Create directory for python files
  file: path=/home/{{ user_name }}/python_files
    state=directory
    owner={{ user_name }}
    group={{ user_name }}
    mode=755

- name: Copy python file over
  copy: 
    src=example.py 
    dest=/home/{{ user_name }}/python_files/example.py
    owner={{ user_name }}
    group={{ user_name }}
    mode=777 

- name: Execute script
  command: /home/{{ user_name }}/python_files/example.py

这是我收到的错误：

部署的服务器上的目录权限看起来正常：

achilles@ansible-test:~/python_files$ ll
total 12
drwxr-xr-x  2 achilles achilles 4096 Apr 12 15:56 ./
drwxr-xr-x 18 achilles achilles 4096 Apr 12 15:56 ../
-rwxrwxrwx  1 achilles achilles  153 Apr 12 15:56 example.py*

有什么建议吗？我不认为我忽略了显而易见的问题，但我对 ansible 还很陌生，而且关联没有帮助。

答案1

为了在另一个目录中运行 Python 脚本，您需要实现一个chdir。Ansible允许您通过其参数执行此操作args。

例子：

- name: Execute Script
  command: python example.py
  args:
    chdir: /home/{{user_name}}/python_files/

答案2

尝试使用绝对路径并仔细检查目标路径是否存在于远程服务器中。

答案3

错误来自 shebang 中 Python 代码的第一行。存在剪切和粘贴错误。
