调用handlers，在tasks的下级notify调用

listen将被调用的多个handlers命名为组名

notify可以指定handlers的name或listen

meta： flush_handlers 指定tasks任务结束就调用handlers

示例如下

[root@jack7-1 ansible]# cat test7.yml

• hosts: PA
  remote_user: root
  tasks:

  • name: check apache
    shell: ss -nlt
    notify: reload

  handlers:

  • name: reload
    service:
    name: httpd
    state: reloaded

示例如下

[root@jack7-1 ansible]# less test6.ym

• hosts: PA
  remote_user: root
  tasks:

  • name: cron
    cron:
    name: echo hello
    user: root
    minute: ‘20‘
    hour: ‘10‘
    job: echo hello jack
    notify: h1

  • meta: flush_handlers

  • name: change 8888 to 8080
    lineinfile:
    path: /etc/httpd/conf/httpd.conf
    backrefs: yes
    regexp: Listen 8888
    line: Listen 8080
    backup: yes
    notify: h2

  handlers:

  • name: reload apache
    listen: h1
    service:
    name: httpd
    state: reloaded
  • name: touch file
    listen: h1
    file:
    path: /root/test.apache
    state: touch
    mode: 0755
    owner: jack
  • name: mkdir hao
    listen: h2
    file:
    path: /root/hao
    state: directory
    owner: jack
    mode: 0777
  • name: reload cron
    listen: h1
    service:
    name: crond
    state: restarted
