 【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)
 (1)环境准备
 节点 地址
 ansible 192.168.100.10
 node1 192.168.100.20
 node2 192.168.100.30
 node3 192.168.100.40
 (2)环境配置
 [root@localhost ~]# hostnamectl set-hostname ansible
 [root@localhost ~]# su
 [root@ansible ~]#
[root@localhost ~]# hostnamectl set-hostname node1
 [root@localhost ~]# su
 [root@node1 ~]#
[root@localhost ~]# hostnamectl set-hostname node2
 [root@localhost ~]# su
 [root@node2 ~]#
[root@localhost ~]# hostnamectl set-hostname node3
 [root@localhost ~]# su
 [root@node3 ~]#
将ip地址映射成主机名(其他3台节点配置一样,此处省略)
[root@ansible ~]# vi /etc/hosts
 192.168.100.10 ansible
 192.168.100.20 node1
 192.168.100.30 node2
 192.168.100.40 node3
 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
#关闭防火墙和selinux(其他3台节点配置一样,此处省略)
 [root@ansible ~]# systemctl stop firewalld && setenforce 0
ansible节点部署ansible服务(通过CRT远程工具将提供的ansible软件包上传到ansible节点)
[root@ansible ~]# tar -xvf ansible.tar.gz
#删除centos自带的源并配置本地yum源安装ansible服务
 [root@ansible ~]# mv /etc/yum.repos.d/* /home/

【题目 2】Ansible 服务部署:部署ELK 集群服务[2 分]
 使用赛项提供的OpenStack 私有云平台,创建三台 CentOS7.9 系统的云主机分别命名为elk-1、elk-2 和elk-3,Ansible 主机可以使用上一题的环境。要求Ansible 节点编写剧本,执行 Ansible 剧本可以在这三个节点部署 ELK 集群服务(在/root 目录下创建 install_elk 目录作为 ansible 工作目录,部署的入口文件命名为 install_elk.yaml)。具体要求为三个节点均安装Elasticserach 服务并配置为 Elasticserach 集群;kibana 安装在第一个节点;Logstash 安装在第二个节点。(需要用到的软件包在 HTTP 服务下)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 ansible 节点,执行 ansible 脚本,准备好环境, 以便考试系统访问)
 1.执行yaml 文件正确计 0.5 分
 2.检查 ELK 服务部署正确计 1.5 分
 (1)配置主机映射:
 修改当前节点主机名为ansible,并修改ansible节点主机映射,命令如下:
 [root@localhost ~]# hostnamectl set-hostname ansible
 [root@localhost ~]# bash
 [root@ansible ~]# cat /etc/hosts
 172.128.11.162 ansible
 172.128.11.217 node1
 172.128.11.170 node2
 172.128.11.248 node3
 配置免密访问,虚拟机root用户密码为000000,命令如下:(考试的时候命名为elk-1、elk-2 和elk-3)
 [root@ansible ~]# ssh-keygen
 [root@ansible ~]# ssh-copy-id node1
 [root@ansible ~]# ssh-copy-id node2
 [root@ansible ~]# ssh-copy-id node3
 将ansible节点的域名解析文件复制给安装Elasticsearch集群服务的三个节点,命令如下:
 [root@ansible ~]# scp /etc/hosts node1:/etc/
 [root@ansible ~]# scp /etc/hosts node2:/etc/
 [root@ansible ~]# scp /etc/hosts node3:/etc/

 [root@ansible example]# rpm -ivh /root/elasticsearch-6.0.0.rpm
 [root@ansible example]# cp -rf /etc/elasticsearch/elasticsearch.yml elk1.yml
 [root@ansible example]# cat elk1.yml | grep -Ev “^KaTeX parse error: Expected group after '^' at position 2: |^̲#" cluster.name…|^#”
 cluster.name: ELK
 node.name: node2
 node.master: false
 node.data: true
 path.data: /var/lib/elasticsearch
 path.logs: /var/log/elasticsearch
 network.host: 172.128.11.170
 http.port: 9200
 discovery.zen.ping.unicast.hosts: [“node1”,“node2”,“node3”]

【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
