Ansible 部署服务

使用赛项提供的 OpenStack 私有云平台，创建 2 台系统为 centos7.5 的云主机，其中一台作为 ansible 的母机并命名为 ansible，另外一台云主机命名为 node1，通过 http 服务中的ansible.tar.gz 软件包在 ansible 节点安装 ansible 服务；并用这台母机，编写 ansible 脚本（在/root 目 录 下 创 建 ansible_ftp 目 录 作 为 ansible 工 作 目 录 ， 部 署 的 入 口 文 件 命 名 为install_ftp.yaml）。install_ftp.yaml 文件中需要完成的内容为
（1）yaml 中被执行节点为 node1，执行者为 root；
（2）使用 copy 模块将 ansible 节点的 local.repo 传到 node 节点；（local.repo 用于配置2021 年职业院校技能大赛“云计算”赛项 赛卷node 节点的 yum 源，可自行创建）
（3）使用 yum 模块安装 ftp 服务；
（4）使用 service 模块启动 ftp 服务。
