本文主要是介绍在线云原生边缘计算KubeEdge安装配置（二），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
1. K8S集群部署，可以参考如下博客
请安装k8s集群，centos安装k8s集群
请安装k8s集群，ubuntu安装k8s集群
请安装kubeedge cloudcore centos安装K8S
2.安装kubEedge
2.1 编辑kube-proxy使用ipvs代理
kubectl edit configmaps kube-proxy -n kube-system #修改kube-proxy
#大约在40多行37 ipvs:38 excludeCIDRs: null39 minSyncPeriod: 0s40 scheduler: ""41 strictARP: true #这里由原来的false修改为true42 syncPeriod: 0s43 tcpFinTimeout: 0s44 tcpTimeout: 0s45 udpTimeout: 0s46 kind: KubeProxyConfiguration47 metricsBindAddress: ""48 mode: "ipvs" #这里原来是空的修改为ipvs49 nodePortAddresses: null50 oomScoreAdj: null51 portRange: ""52 showHiddenMetricsForVersion: ""53 winkernel:54 enableDSR: false55 forwardHealthCheckVip: false56 networkName: ""57 rootHnsEndpointName: ""58 sourceVip: ""kubectl rollout restart daemonset kube-proxy -n kube-system
kubectl get pods -n kube-system
2.2 基础服务提供，负载均衡器metallb
#无网络情况下，先上传kubeedge.tar 和 metallb-native.yaml文件
docker load -i kubeedge.tar #导入镜像#有网络可以直接拉去镜像
docker pull quay.io/metallb/controller:v0.13.5
docker pull quay.io/metallb/speaker:v0.13.5
wget https://raw.githubusercontent.com/metallb/metallb/v0.13.5/config/manifests/metallb-native.yaml
kubectl apply -f metallb-native.yaml

测试通过
kubectl delete -f nginx.yaml #删除无用的pod和svc
yum install iptables-services -y #安装iptables后期有用
systemctl start iptables.service
systemctl enable iptables.service
systemctl status iptables.service
3. 对于kubeEdge概述
KubeEdge由云和边缘组成。它建立在Kubernetes之上，为联网应用部署和云与边缘之间的元数据同步提供核心基础设施支持。所以如果我们想要设置KubeEdge，我们需要设置Kubernetes集群(可以使用现有的集群)，云端和边缘端在cloud side, 我们需要安装
Docker
Kubernetes cluster
cloudcore
在 edge side, 我们需要安装
Docker
MQTT （配置可以选用，不是一定需要）
edgecore
3.部署kubeedge cloudcore(主节点)
3.1 获取keadm工具
wget https://github.com/kubeedge/kubeedge/releases/download/v1.10.1/keadm-v1.12.1-linux-amd64.tar.gztar -zxvf keadm-v1.12.1-linux-amd64.tar.gz
cp keadm-v1.12.1-linux-amd64/keadm/keadm /usr/local/bin/
keadm version
3.2 部署cloudcore
#在master上部署
#设置云端 使用keadm初始化，安装cloudcore
docker pull kubeedge/cloudcore:v1.14.2
docker pull kubeedge/iptables-manager:v1.14.2keadm init --advertise-address=192.168.186.200 --set iptablesManager.mode="external" --profile version=v1.12.1 #这里的IP是负载均衡器metallb分配的IP，如果是云服务器则用公网#以上参数分别为master节点地址和要安装的KubeEdge版本。#keadm reset #安装错误可以重置
keadm gettoken #获取token
[root@k8s-ke-cloud docker]# kubectl get deployment -n kubeedge #上述多此执行后依然不行
NAME READY UP-TO-DATE AVAILABLE AGE CONTAINERS IMAGES SELECTOR
cloudcore 0/1 1 0 7m2s cloudcore kubeedge/cloudcore:v1.12.1 k8s-app=kubeedge,kubeedge=cloudcore
[root@k8s-ke-cloud docker]# kubectl delete deployment -n kubeedge #删除这个deployment
error: resource(s) were provided, but no name was specified
[root@k8s-ke-cloud docker]# kubectl delete deployment cloudcore -n kubeedge
deployment.apps "cloudcore" deleted
[root@k8s-ke-cloud docker]# [root@k8s-master01 ~]# keadm init --advertise-address=192.168.186.200 --set iptablesManager.mode="external" --profile version=v1.12.1
Kubernetes version verification passed, KubeEdge installation will start...
CLOUDCORE started

至此cloudcore部署完毕
