EX294: Create a static host inventory file

This blog is just a simple example of static inventories, more information can be found at Ex294: Inventories.

1 Default inventory file

The default inventory file is /etc/ansible/hosts, which will be created automatically during the installation of Ansible.

2 Using non-default inventory files

Both "ansible" and "ansible-playbook" support a command-line option "-i" or "--inventory" to specify inventory.

ansible all -i ./myhosts -m shell -a 'hostname'

ansible-playbook --inventory=./myhosts playbook.yml
