To install a the CLI alone on a separate system, do the following:

1. Use the dnf config-manager tool to enable the yum repositories and do one of the following:
   • If you are using ol8_UEK6, use the following command:

     sudo dnf config-manager --enable ol8_UEKR6 ol8_appstream

   • If you are using ol8_UEK7, use the following command:

     sudo dnf config-manager --enable ol8_UEKR7 ol8_appstream

2. Ensure that no version of ansible is present on the system. If any are, uninstall them. For example, the following shows that there are no versions of ansible installed:

   rpm -q ansible
   package ansible is not installed

3. Install the CLI:

   sudo dnf install ansible-core

You interact with the CLI by entering commands with a series of options. The CLI command with the --help flag returns the following syntax information:

ansible-galaxy --help
usage: ansible-galaxy [-h] [--version] [-v] TYPE ...

Perform various Role and Collection related operations.

positional arguments:
  TYPE
    collection   Manage an Ansible Galaxy collection.
    role         Manage an Ansible Galaxy role.

options:
  --version      show program's version number, config file location, configured module search path, module location, executable location and exit
  -h, --help     show this help message and exit
  -v, --verbose  Causes Ansible to print more debug messages. Adding multiple -v will increase the verbosity, the builtin plugins currently evaluate up to -vvvvvv. A
                 reasonable level to start is -vvv, connection debugging might require -vvvv.

The positional arguments section lists the available resources to manage using the CLI. You can obtain additional information about these resources by adding the resource name before the --help flag. For example, the following shows actions available for the collection resource:

ansible-galaxy collection --help
usage: ansible-galaxy collection [-h] COLLECTION_ACTION ...

positional arguments:
  COLLECTION_ACTION

                     server and the installed copy. This does not verify
                     dependencies.
