2023云计算国赛样题梳理

typora-root

模块三 公有云(40)

任务1 公有云服务搭建(5分)

3.1.1 私有网络管理

在公有云中完成虚拟私有云网络的创建。

3.1.2 云实例管理

登录公有云平台,创建两台云实例虚拟机。
3.1.3 管理数据库

使用intnetX-mysql网络创建两台chinaskill-sql-1和chinaskill-sql-2云服务器,并完成MongoDB安装。

##创建云服务器与上一步一样
##node1与node2进行一样的操作

3.1.4 主从数据库

在chinaskill-sql-1和chinaskill-sql-2云服务器中配置MongoDB主从数据库。

#修改配置文件
[root@node1 ~]# vi /etc/mongod.conf 
bindIp: 0.0.0.0
replication:
  replSetName: test
#重启服务
[root@node1 ~]# systemctl restart mongod.service
#查看集群状态

3.1.8 NAT网关

根据要求创建一个公网NAT网关。

3.1.9云服务器备份

创建一个云服务器备份存储库名为server_backup,容量为100G。将ChinaSkill-node-1云服务器制作镜像文件chinaskill-image。

3.1.10 负载均衡器

根据要求创建一个负载均衡器chinaskill-elb。

3.1.11 弹性伸缩管理

根据要求新建一个弹性伸缩启动配置。

任务2 公有云服务运维(10分)

3.2.1 云容器引擎

在公有云上,按照要求创建一个x86架构的容器云集群。

3.2.2 云容器管理

使用插件管理在kcloud容器集群中安装Dashboard可视化监控界面。

3.2.3 使用kubectl操作集群

在kcloud集群中安装kubectl命令,使用kubectl命令管理kcloud集群。

#1 安装kubectl
其实node上是已经安装了kubectl的,但是会报这个错:
[root@kcloud-server ~]# kubectl get node
The connection to the server localhost:8080 was refused - did you specify the right host or port?
#这个其实是因为没有配置文件和环境变量的原因,为了记录整个过程,我把node节点上原有的kubectl卸载了。
然后重新安装:

先配置yum源(建议使用阿里的源,华为的不好用,期待完善)

cat <<EOF > /etc/yum.repos.d/kubernetes.repo

[kubernetes]

name=Kubernetes

baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/

enabled=1

gpgcheck=1

repo_gpgcheck=1

gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg

EOF

然后开始安装,注意,版本一定要和集群的版本对应
[root@kcloud-server ~]# yum install -y kubectl-1.25.1
2 下载配置文件

这个在官网的页面按照操作进行就行(链接:https://console.huaweicloud.com/cce2.0/?agencyId=07fb10cb020026b81f90c00e0ba587f6&region=cn-east-3&locale=zh-cn#/app/resource/cluster/detail/accessAPI?clusterName=test&clusterId=7631fcee-894f-11ec-b434-0255ac1002c7&type=api)

点这里:
3 安装和配置kubectl

mkdir -p $HOME/.kube
mv -f kubeconfig.json $HOME/.kube/config

4 切换kubectl的访问模式
[root@kcloud-server home]# kubectl get node
NAME          STATUS   ROLES    AGE   VERSION
172.16.1.25   Ready    <none>   14m   v1.25.3-r0-25.1.23

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-ZJQFQg5W-1686127383486)(/k8s2.png)]

3.2.4 安装Helm

使用提供的Helm软件包,在kcloud集群中安装Helm服务。

[root@kcloud-21836 ~]# tar -zxvf helm-v3.10.1-linux-amd64.tar.gz 
linux-amd64/
linux-amd64/helm
linux-amd64/LICENSE

3.2.5 根据提供的chart包mariadb-7.3.14.tgz部署mariadb服务,修改mariadb使用NodePort模式对其进行访问。

[root@kcloud-21836 ~]# helm install mariadb mariadb/
NAME: mariadb

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-EXoqGGhZ-1686127383486)(/mariadb1.png)]

3.2.6 在k8s集群中创建mariadb命名空间,根据提供的chart包mariadb-7.3.14.tgz修改其配置,使用NodePort模式对其进行访问。

[root@kcloud-21836 ~]# cat mariadbnamespace.yaml 
apiVersion: v1

3.2.11 私有仓库管理

在master节点添加搭建的本地私有chart仓库源,并上传wordpress-13.0.23.tgz包至chartmuseum私有仓库中。可以使用本地仓库chart源部署应用。

#为/data/charts授予777权限
chmod 777 /data/charts/
#查看svc
[root@kcloud-server ~]# kubectl get svc -n chartmuseum

3.2.15 ChartMuseum仓库部署

在k8s集群中创建chartmuseum命名空间,编写yaml文件在chartmuseum命名空间中使用chartmuseum:latest镜像创建本地私有chart仓库。

apiVersion: v1
kind: Namespace
metadata:
  name: chartmuseum
---
apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: chartmuseum
  name: chartmuseum
  namespace: chartmuseum
spec:
  replicas: 1
  selector:
    matchLabels:
      app: chartmuseum
  strategy:
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 1
    type: RollingUpdate
  template:
    metadata:
      labels:
        app: chartmuseum
    spec:
      containers:
      - image: chartmuseum/chartmuseum:latest
        imagePullPolicy: IfNotPresent
        name: chartmuseum
        ports:
        - containerPort: 8080
          protocol: TCP
        env:
        - name: DEBUG
          value: "1"
        - name: STORAGE
          value: local
        - name: STORAGE_LOCAL_ROOTDIR
          value: /charts
        resources:
          limits:
            cpu: 500m
            memory: 256Mi

      volumes:
      - name: charts-volume
        nfs:
          path: /data/charts
          server: 192.168.200.10
      restartPolicy: Always

  namespace: chartmuseum
spec:
  ports:
    - port: 8080
      protocol: TCP
      targetPort: 8080
  selector:
    app: chartmuseum

3.2.16 生命周期管理-配置Pod生命周期

登录kcloud集群节点,在default命名空间下创建一个名Pod,并进行Pod生命周期管理。

##nginx为例
apiVersion: v1
kind: Pod
metadata: 
  name: pod-hook-exec
  namespace: dev
spec:
  containers:
  - name: main-container
    image: nginx:1.17.1
    ports: 
    - name: nginx-port
      containerPort: 80
    lifecycle:
      postStart:
        exec: #在容器启动的时候执行一个命令,修改掉nginx的默认首页内容
          command: ["/bin/sh","-c","echo postStart... > /usr/share/nginx/html/index.html"]
      preStop: #在容器停止之前停止nginx服务
        exec:
          command: ["/usr/sbin/nginx","-s","quit"]

3.2.17 定时任务管理—创建定时任务

在kcloud集群节点/root目录下编写yaml文件date.yaml完成定时管理任务。

apiversion: batch/vl beta 
kind: CronJob
metadata:
	name: hello
spec:
	schedule: "*/1 * * * *"
	jobTemplate:
		spec:
			template:
				spec:
					containers:
					- name:hello
					  image:busybox
					  args:
					  - /bin/sh
					  - -C
					  - date;echo Hello from the Kubernetes cluster restartPolicy:OnFailure

3.2.18 HPA管理—创建HPA规则

在kcloud集群节点/root目录下编写YAML文件hpa.yaml,完成HPA管理。

[root@k8s-master-node1 ~]# cat web.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: web
  namespace: default
spec:
  replicas: 1
  selector:

        image: nginx:latest
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 80

        resources:
          requests:
            cpu: 500m  # 指定所需的 CPU 资源 request
[root@k8s-master-node1 ~]# cat hpa.yaml
apiVersion: autoscaling/v2beta2
kind: HorizontalPodAutoscaler
metadata:
  name: web
  namespace: default
spec:
  scaleTargetRef:
    apiVersion: apps/v1
    kind: Deployment

[root@k8s-master-node1 ~]# kubectl apply -f web.yaml
[root@k8s-master-node1 ~]# kubectl apply -f deployment.yaml
[root@k8s-master-node1 ~]# kubectl apply -f hpa.yaml

3.2.19 使用Helm模板
