You will need to generate a key pair on your control node and transfer the public key to the managed nodes. Now that Ansible is installed, you must configure SSH key-based authentication (which uses asymmetric cryptography) from the control node to the managed nodes for Ansible to work seamlessly. Python version = 3.6.8 (default, Oct 11 2019, 15:04:54) Īfter the installation, you can make changes to the default Ansible settings by modifying parameters in the ansible.cfg file.

# ansible -versionĬonfigured module search path = Īnsible python module location = /usr/local/lib/python3.6/site-packages/ansible-2.9.6-p圓.6.egg/ansibleĮxecutable location = /usr/local/bin/ansible

This command installs six packages:Īfter the installation, run the ansible -version command to check the version of Ansible installed. To install Ansible on the RHEL 8 control node after registering with the Satellite server, run the command yum install ansible.

Repository' ansible-2.9-for-rhel-8-x86_64-rpms' is enabled for this system. # subscription-manager repos -enable ansible-2.9-for-rhel-8-x86_64-rpms Repository' satellite-tools-6.6-for-rhel-8-x86_64-rpms' is enabled for this system. On the control node, you must register with the Satellite server, enable the Satellite tools, and enable the Ansible repository by using the following commands: # subscription-manager repos -enable satellite-tools-6.6-for-rhel-8-x86_64-rpms If you are using RHEL Satellite to install Ansible on an RHEL 8 system, make sure you add the repositories for Red Hat Ansible Engine 2.9 for RHEL 8 x86_64 (RPMs) from the Satellite GUI and sync the repositories from the CDN to the Satellite. Managed nodes can also use SFTP or SCP for communication, and this can be modified in the Ansible configuration file ( ansible.cfg). By default, Ansible uses SSH to communicate with managed nodes. To use all Ansible modules, you need to install Python on the managed nodes as well. With RHEL 7, we have Python 2.7 installed by default, and with RHEL 8, we have Python 3.6 by default. You can install Ansible on any machine with Python 2 (version 2.7) or Python 3 (versions 3.5 and higher). To use Ansible in your environment, you must set up a management node (also called a control node) where you will install Ansible. Check out the first article, Demystifying Ansible for Linux sysadmins, if you have not already. In this article, I discuss the prerequisites for installing Ansible, Ansible installation using the Satellite server, setting up Ansible for automation, introduction to playbooks, inventory files, and go through a use case for Ansible.
