Chapter 8. Install Private Automation Hub

With all the prerequisites set and in place, the final step is to modify the inventory file for a clustered automation hub installation and run setup.sh.

Within this reference environment, the controlplane-1.site1.example.com system is used to run the setup.sh for the clustered automation hub environment as it can access all the nodes.

Note

The following installation is done on site Ansible Site 1 of this reference environment Ansible Automation Platform cluster. After completion, ensure to follow the same steps for Ansible Site 2.

On controlplane-1.site1.example.com, as the ansible user, perform the following:

  1. Change directory into ansible-automation-platform-setup-2.1.0-1.tar.gz 

    cd ansible-automation-platform-setup-2.1.0-1/
    Copy to Clipboard Toggle word wrap

  2. Backup the existing inventory file 

    $ cp inventory inventory-controller.bkup
    Copy to Clipboard Toggle word wrap

  3. Modify the inventory file to include with the appropriate information about your environment. Below is an example of this reference environment.

  5. Encrypt the credentials_ah.yml file using ansible-vault. 

    $ ansible-vault encrypt credentials_ah.yml
    Copy to Clipboard Toggle word wrap 
    New Vault password:
Confirm New Vault password:
