3. create the ansible.cfg configuration file, and add the inventory and roles path.

NOTE: you can always use the Ansible global configuration file (/etc/ansible/ansible.cfg) as a reference in case you forget any key-value pair to use in the configuration file.

[lisa@drdev1 ~]$ vim /home/lisa/ansible/ansible.cfg
[defaults]
inventory=/home/lisa/ansible/inventory
roles_path=/home/lisa/ansible/roles
ask_pass=false
remote_user=root

[privilege_escalation]
become=true
become_method=sudo
become_user=root
become_ask_pass=false

4. Verify the inventory configuration

[controller@drdev1 ~]$ cd /home/lisa/ansible/
[lisa@drdev1 ansible]$ ansible --list-hosts all
  hosts (5):
    host1.tekneed.com
    host2.tekneed.com
    host3.tekneed.com
    host4.tekneed.com
    host5.tekneed.com

5. Verify the current Ansible configuration file.

[lisa@drdev1 ansible]$ ansible --version

ansible 2.8.18
  config file = /home/lisa/ansible/ansible.cfg
  configured module search path = ['/home/lisa/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3.6/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 3.6.8 (default, Oct 11 2019, 15:04:54) [GCC 8.3.1 20190507 (Red Hat 8.3.1-4)]
