【题目 1】Ansible 服务部署：部署 MariaDB 集群[2 分]

使用OpenStack 私有云平台，创建 4 台系统为centos7.9 的云主机，其中一台作为 Ansible 的母机并命名为 ansible，另外三台云主机命名为 node1、node2、node3；使用这一台母机，编写 Ansible 脚本（在/root 目录下创建 example 目录作为 Ansible 工作目录，部署的入口文件命名为 cscc_install.yaml ） ， 对其他三台云主机进行安装高可用数据库集群 （MariaDB_Galera_cluster，数据库密码设置为 123456）的操作（所需的安装包在 HTTP 服务中）。完成后提交 Ansible 节点的用户名、密码和 IP 地址到答题框。（考试系统会连接到你的Ansible 节点，去执行 Ansible 脚本，请准备好 Ansible 运行环境，以便考试系统访问）

【题目 4】Python 运维开发：基于 Openstack Python SDK 实现云主机创建[1 分]

使 用 已 建 好 的 OpenStack Python 运 维 开 发 环 境 ，在 /root 目 录 下 创 建sdk_server_manager.py 脚本，使用 python-openstacksdk Python 模块，完成云主机的创建和查询。创建之前查询是否存在"同名云主机"，如果存在先删除该镜像。

（1）创建 1 台云主机：云主机信息如下：

云主机名称如下：server001

镜像文件：cirros-0.3.4-x86_64-disk.img

云主机类型：m1.tiny

网络等必要信息自己补充。

（2）查询云主机：查询云主机 server001 的详细信息，并以 json 格式文本输出到控制台。 完成后提交 OpenStack Python 运维开发环境 Controller 节点的 IP 地址，用户名和密码提交。

1.执行 sdk_server_manager.py 脚本,成功创建云主机，计 0.5 分

2.检查创建的云主机状态正确，计 0.5 分

（1）代码实现

创建云主机所需的镜像、类型、网络是用name来识别的，需要提前创建好
