前提：node1与node2已经挂载好光盘且搭建好yum仓库

ansible实验：剧本，安装httpd服务_ansible

- name: install httpd
  hosts: node1,node2,node3                #被控主机
  remote_user: devops                      #用什么用户执行
  gather_facts: false                      #获取主机信息
  tasks:
          - name: yum install httpd
            yum:
                    name: httpd
                    state: present
          - name: start httpd
            systemd:
                    name: httpd
                    state: started
                    enabled: yes
