Automate shutdown command via Ansible playbook

[xinhua...@gmail.com]

I'm using ansible 2.9. There is no shutdown module available.

I need to automate shutdown command via Ansible playbook. The target hosts are different distributions of CentOS servers - 7 or 6. When I ran the playbook to shutdown them, the execution will hang forever for one of CentOS 7 servers. I had to hit Ctrl-C. The execution stopped when example8 is down. It is CentOS 7. The example7 is CentOS 6 and does not hang forever.

inventory file:

[shutdown_300]
example1

[shutdown_301]
example2

[shutdown_302]
example3

[shutdown_303]
example4

[shutdown_304]
example5

[shutdown_305]
example6

[shutdown_306]
example7

example8

[shutdown_30:children]
shutdown_306
shutdown_305
shutdown_304
shutdown_303
shutdown_302
shutdown_301
shutdown_300

Here is the playbook:

---
- hosts: shutdown_30
  gather_facts: no

  tasks:
    - name: Shutdown order 30 
      raw: shutdown -h now
      ignore_unreachable: true
      ignore_errors: true

command to run the playbook:

ansible-playbook -i inventory shutdown.yml

Is there better way to prevent hang because the host is down?

Don't waste time on working around problems in unsupported software.

Instead use the energy to upgrade to something supported.

A more recent version is not published as an RPM for RHEL systems. If
you want one, I publish tools to build RPMs for it at

You probably have no use for the current ansible package. It is a very
bulky agglomeration of roughly 100 ansible collection modules, and
*all* the necessary scripts and python modules for basic ansible
operation are in the ansible-core package. I suspect that if you rip
out ansible, install ansible-core, and install the ansible collection
modules on if and when needed, you will have a much more stable
ansible setup.
