Ansible a little trial.

After we've installed the ansible,

Password-free login is configured.

Now we can check the connectivity of management hosts and managed hosts

Ansible all-m Ping

In our actual production we tend to use sudo to perform root permissions for ordinary users.

Ansible all-m ping-u Ansible-sudo

We can find a directory to create a host list file inventory.cfg

If we create it in the home directory,

Cat/home/inventory.cfg

[Webservers]
192.168.220.98
192.168.220.116

Ansible all-m ping-i inventory.cfg

To specify the host list here, we can also place the inventory.cfg file somewhere else.

For example, if we put it in the/etc/ansible directory, we need to specify a detailed location here.

Ansible all-m ping-i/etc/ansible/inventory.cfg

Note: You often need to get details of the execution process when debugging an Automation script in Ansible, you can add a-V or a-VVV after the command to get detailed output results

Ansible all-m Ping-v

Ansible all-m PING-VVV
