== Managed node requirements

// Source : https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html //

The managed node (the machine that Ansible is managing) does not require Ansible to be installed, but requires **Python 2.7**, or **Python 3.5 - 3.11** to run Ansible-generated Python code

== RHEL 6 utilizes Python 2.6

// Source : https://access.redhat.com/articles/6977724 //

RHEL 6 utilizes Python 2.6, and with the release of Ansible Core 2.13, managed nodes running Python 2.6 are no longer supported

=== Frequently asked questions

Question: RHEL 6 and RHEL 7 include newer versions of Python in the Software Collections repositories, can I install a newer version of Python so that newer versions of Ansible Core will still support these RHEL releases? This will not work, as the Python bindings for items such as yum are contained within the yum package, and the bindings are only included for the version of Python shipped with the respective RHEL release (Python 2.6 for RHEL 6, Python 2.7 for RHEL 7).

Question: I have RHEL 6 systems I need to manage with Ansible – what options do I have? Ansible Core 2.13, planned to be included with RHEL 8.7 and 9.1, is planned to remove support for RHEL 6 clients. For the RHEL System Roles use case, **one option would be to use Ansible Engine 2.9** on a RHEL 7 or RHEL 8 control node. Ansible Engine 2.9, for the RHEL System Roles use case follows the life cycle dates of Ansible Automation Platform version 1.2 as specified on the Red Hat Ansible Automation Platform Life Cycle page.

== Adding Python 2.7 to RHEL6 

// Source : https://access.redhat.com/solutions/92933 //

Python 2.7 (and Python 3.3) is available through the Red Hat offering called Red Hat Software Collections (RHSCL).

Once the RHSCL repository is added to the system's repositories, then Python 2.7 can be installed with yum such as:
Raw
yum install python27-python


-------------------------

== Install Python 2.7 with Software Collections

// Source : https://docs.datastax.com/en/jdk-install/doc/jdk-install/installPython27RHEL.html //

** Not supported **

Verify your Python version:
<code bash> 
python -V
</code>

If Python is not version 2.7.x, install it from the Software Collections ( SCL ) Repository: 
<code bash>
sudo yum update
sudo yum install scl-utils
sudo yum install centos-release-scl-rh
sudo yum install python27
sudo scl enable python27 bash
</code>


Verify the update: 
<code ->
$ python -V
Python 2.7.8
</code>

After logging out or restarting, you must enable python 2.7: 
<code bash>
sudo scl enable python27 bash
</code>

== Utiliser un Execution Environment avec un Ansible Engine en 2.9

Une autre façon est d’utiliser un Exécution Environment avec un Ansible Engine en 2.9.

Par exemple : « Automation Hub Ansible Engine 2.9 execution environment », parce que Ansible 2.9 support RH6.

Avec cette approche il n’est pas nécessaire de modifier les cibles. Par contre il sera probablement nécessaire de faire évoluer l’Execution Envionment.
