First, host planning Create 4 virtual machines as a demo ansible environment, install the operating system as CentOS 7.4. 1 of them as management host, the other 3 as the managed host. IP and host name are: IP host name note 192.168.128.10 Ansible-manager Management host 192.168.128.11 Ansible-demo1 managed host 1 192.168.128.12
