建立对应目录站点

| [root@m01 ~]# mkdir -p /etc/ansible/ansible_playbook/file

注意：上面命令用于建立存放 ansible-playbook 文件的目录。
编写基础模块的 Playbook
实现如下功能：
- 基础仓库准备；
- 安装 rsync 服务端；
- 安装 nfs-utils 服务端；
- 创建 www 用户指定 UID/GID；
- 准备 rsync 客户端密码文件。

编写应用模块 rsync 的剧本：
- 安装 rsync 服务端；
- 配置 rsync 服务端；
- 启动 rsync 服务端；
- 准备对应的数据存储仓库/backup、/data 并授权为 www；
- 准备虚拟用户和密码文件权限 600；
- 变更配置，重载服务。
准备对应配置文件存放至/etc/ansible/ansible_playbook/files/：
