Ansible : Use Playbook#4
2015/07/15 |
|
To use "notify", "handlers", it's possible to execute a task which is defined in "handlers" after a task completed which has "notify" method.
|
|
| [1] | For example, create a Playbook which sshd is restarted after editing sshd_config. |
|
[cent@dlp ~]$
vi playbook_sample.yml
- hosts: target_servers
become: yes
become_method: sudo
handlers:
- name: restart sshd
service: name=sshd state=restarted
tasks:
- name: edit sshd_config
lineinfile: >
dest=/etc/ssh/sshd_config
regexp="{{ item.regexp }}"
line="{{ item.line }}"
with_items:
- { regexp: '^#PermitRootLogin', line: 'PermitRootLogin no' }
notify: restart sshd
tags: Edit_sshd_config
