ansible自己总结（playbook）
#这个是你选择的主机- hosts: webservers
#这个是变量
vars:
http_port: 80
max_clients: 200
#远端的执行权限
remote_user: root
tasks:
#利用yum模块来操作
- name: ensure apache is at the latest
version
yum: pkg=httpd state=latest
- name: write the apache config file
template: src=/srv/httpd.j2
dest=/etc/httpd.conf
#触发重启服务器
notify:
- restart apache
- name: ensure apache is running
service: name=httpd state=started
#这里的restart
apache 和上面的触发是配对的。这就是handlers的作用。相当于tag
handlers:
- name: restart apache
service: name=httpd state=restarted
