playbook作业

创建Web内容目录
按照下方所述，创建一个名为 /home/student/ansible/webcontent.yml 的 playbook：
该 playbook 在 dev 主机组中的受管节点上运行
创建符合下列要求的目录 /webdev：
所有者为 devops 组
具有常规权限：owner=read+write+execute，group=read+write+execute，other=read+execute
具有特殊权限: set group ID
用符号链接将/webdev目录链接到/var/www/html/webdev
创建文件 /webdev/index.html，其中包含如下所示的单行文本：Development
在 dev 主机组中主机上浏览此目录（例如 http://node1.example.com/webdev/ ）将生成以下输出：
Development

[student@ansible ansible]$ vim webcontent.yml
