一 、handlers和notify结合触发条件
handlers(触发器): 定义一些task列表,与之前剧本中task没有关系,只有资源发送变化才会采取一定的操作
notify:notify中调用handler中定义的操作
二、修改配置文件,重启服务
1、yum安装httpd
[root@linux-node1 ~]# tree ansible/ ansible/ ├── files │ └── httpd.conf ├── file.yaml └── httpd.yaml
[root@linux-node1 ansible]# cat httpd.yaml
---
- hosts: date
remote_user: root
tasks:
- name: install httpd package
yum: name=httpd
- name: copy conf file
copy: src=files/httpd.conf dest=/etc/httpd/conf backup=yes
- name: start service
service: name=httpd state=started enabled=yes
2、修改配置文件端口8081,在次执行,httpd服务没有重启
[root@linux-node1 ansible]# cat httpd.yaml
---
- hosts: date
remote_user: root
tasks:
- name: install httpd package
yum: name=httpd
- name: copy conf file
copy: src=files/httpd.conf dest=/etc/httpd/conf backup=yes
notify: restart service
- name: start service
service: name=httpd state=started enabled=yes
handlers:
- name: restart service
service: name=httpd state=restarted


三、定义多个notify
ansible-playbook 之handlers和notify(三)
