Ansible Playbook 仅在特定服务器上失败

Question

下面的 ansible-playbook 连接对我的所有服务器都正常工作，除了 dest_svr。以下命令失败。

ansible-playbook -vvvv /opt/test/Auto/site.yml  -i /opt/test/Auto/hosts.txt -e "source_host=dest_svr execmd=echo source_user=user2"

源 Ansible 服务器详细信息：

现在目标服务器详细信息：

user2@dest_svr:~$ uname -a

user2@dest_svr:~$ python --version                                                                                                                                                                                    
Python 2.7.14

注意：我只想更改我的剧本，不希望更改 ansible.cfg 中的任何内容，因为其他剧本不应受到影响。

Answer 1

据我所知，这是由以下原因造成的：

line 3: _ANSIBALLZ_WRAPPER: command not found

即this line, but a little digging seems to imply that SunOS shebang lines do not tolerate pointing to an executable that is, itself, also a shebang:

据我所知，修复方法是设置 -e ansible_python_interpreter=/the/path/to/the/real/python 或者我已经看到 some folks try -e 'ansible_python_interpreter="/bin/env python"' (I modified the path to env since apparently SunOS 在 /usr/bin/env 中没有 env 但是我没有 SunOS 实例来验证该理论，因此 买者自负)
