AIX Open Source

Hi Team,

I am trying to setup ansible on AIX, so we have installed ansible and python on AIX servers. On client one of the server having python2 and other having python3. 

I am not sure how python2 was installed, it seems it was installed manually with all dependency altogether with rpm command.

Python3 was installed with dnf install command, so everything was installed automatically and updated. Python3 client is not working because having some link with other directory but python2 is working fine which is having link with /usr/bin/ directory. So I am not sure which is the correct way of doing this setup. 

Would you please help?

Hi Manoj,

Ansible looks for python interpreter in /usr/bin/python. Old RPM packages created a symlink in /usr/bin for python binaries. New RPM packages don't do it anymore. Because you didn't provide any error message, I can suppose that this is the reason for your failure - the failing server doesn't have /usr/bin/python.

The choices you have:

• create symlinks in /usr/bin. I wouldn't recommend unless you know what you're doing.
• add a variable ansible_python_interpreter: /opt/freeware/bin/python3 in your playbooks. This is my favourite way of solving the problem.
• add a global configuration interpreter_python = /opt/freeware/bin/python3 in /opt/freeware/etc/ansible/ansible.cfg on your Ansible controller node.

Hello Andrey,

I try to update ansible.cfg with below content. But still getting same error. Can you please check whether added variable is correct or not? Anything else we need to do.

This is my ansible.cfg file, in lieu of discovered_interpreter_python I used ansible_python_interpreter but same issue. I also try to use this ansible_python_interpreter: /opt/freeware/bin/python3 

 cat ansible.cfg
[defaults]

log_path=/home/automation/ansible/systemfiles/ansible_logs
discovered_interpreter_python=/opt/freeware/bin/python3
forks=10
