我是 ansible 的新手，正在尝试自动化一些步骤。

此任务第一次运行良好。

# Copy Root ssh keys within all devices
- hosts: etall
  tasks:
    - name: ssh keygen
      command: ssh-keygen -t rsa -f /root/.ssh/id_rsa -q -P ""

第二次它只是在收集事实后挂起。设置ANSIBLE_DEBUG=1显示挂在的步骤：

16584 1554867575.39541: _low_level_execute_command(): executing: /bin/sh -c '/usr/bin/python /root/.ansible/tmp/ansible-tmp-1554867574.524454-229535370546451/AnsiballZ_command.py && sleep 0'

在客户端机器上跟踪时：

/usr/bin/python -m trace --trace /root/.ansible/tmp/ansible-tmp-1554873279.0459487-106888464136363/AnsiballZ_command.py

<---output snippet---->
AnsiballZ_command.py(16):     import base64

    import base64
ImportError: No module named base64

我可以import base64之后/usr/bin/python

这在第一次运行时不是问题。在客户端计算机上重新安装操作系统后也可以使用。

版本：

ansible 2.7.6
  config file = /user/user1/plays/ansible.cfg
  configured module search path = ['/user/user1/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /user/user1/p363/lib/python3.6/site-packages/ansible-2.7.6-py3.6.egg/ansible
  executable location = /user/user1/p363/bin/ansible
  python version = 3.6.3 (default, Jul  8 2018, 21:13:48) [GCC 4.8.5 20150623 (Red Hat 4.8.5-28)]

客户端机器中的 Python 版本是 2.7.5

配置 

ansible-config dump --only-changed
DEFAULT_FORKS(/user/user1/plays/ansible.cfg) = 1
DEFAULT_HOST_LIST(/user/user1/plays/ansible.cfg) = ['/user/user1/plays/hosts.ini']

收集事实后挂起。

这在第一次运行时完成得很好。在客户机上重新安装操作系统后也能正常工作。
