引言
本萌新在搭建KubeEdge时踩了很多坑，走了很多弯路，浪费了很多时间，大多数问题都是墙的原因。此贴尽可能采用了手动部署yaml文件的方式，最终部署成功，故记录过程用于反思与回顾，请大神多多批评指正。
正文
一、环境准备，两节点都需要配置
1.1、主机准备
| 主机名 | IP地址 | 最低配置 | 操作系统 | 内核版本 |
|---|---|---|---|---|
| ke-cloud | 192.168.129.135 | 4C 4G | CentOS 7.6 | 3.10.0-957.el7.x86_64 |
| ke-edge1 | 192.168.129.136 | 2C 2G | CentOS 7.6 | 3.10.0-957.el7.x86_64 |
1.2、关闭防火墙和selinux
$ systemctl stop firewalld
$ systemctl disable firewalld
# 临时关闭
$ setenforce 0
# 永久关闭
$ sed -i 's/enforcing/disabled/' /etc/selinux/config
1.3、关闭swap分区，若没有swapp分区可以忽略不进行操作
$ swapoff -a
$ sed -i 's/.*swap.*/#&/' /etc/fstab
1.4、主机名解析
#添加hosts
$ cat >> /etc/hosts << EOF
192.168.129.140 cloud
192.168.129.141 edge1
140.82.114.3 github.com
EOF
二、kubeadm安装kubernetes集群
2.1、安装docker (两节点都需要安装)
#1、安装docker依赖软件包
$ sudo yum install -y yum-utils device-mapper-persistent-data lvm2
#2、添加Yum源，国内源速度快很多
#国内源安装快很多
$ sudo yum-config-manager \
--add-repo https://mirrors.ustc.edu.cn/docker-ce/linux/centos/docker-ce.repo
#3、安装docker-ce
$ yum install docker-ce docker-ce-cli containerd.io -y
$ systemctl start docker && systemctl enable docker
systemctl start cloudcore.service && systemctl enable cloudcore.service
$ docker info |grep Cgrou
#4、验证安装是否成功
$ docker version

# 快照《安装docker》
2.2、安装k8s集群，只需要在ke-cloud上进行安装，ke-edge1不需要join到集群
#1、配置内核参数，将桥接的IPv4流量传递到iptables的链
$ cat > /etc/sysctl.d/k8s.conf <<EOF
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
$ sysctl --system
#2、配置国内kuberneetes的yum源，由于网络原因，中国无法直接连接到google的网络，需要配置阿里云的yum源
$ 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
#3、安装kubectl、kubeadm、kubelet
$ yum install -y kubelet-1.17.1 kubeadm-1.17.1 kubectl-1.17.1
//输出信息
Installed:
kubeadm.x86_64 0:1.17.1-0 kubectl.x86_64 0:1.17.1-0 kubelet.x86_64 0:1.17.1-0
Dependency Installed:
conntrack-tools.x86_64 0:1.4.4-7.el7 cri-tools.x86_64 0:1.19.0-0 kubernetes-cni.x86_64 0:0.8.7-0
libnetfilter_cthelper.x86_64 0:1.0.0-11.el7 libnetfilter_cttimeout.x86_64 0:1.0.0-7.el7 libnetfilter_queue.x86_64 0:1.0.2-2.el7_2
socat.x86_64 0:1.7.3.2-2.el7
$ systemctl enable kubelet
$ reboot
#4、初始化集群，在cloudmaster上执行kubeadm init
$ kubeadm init --kubernetes-version=1.17.1 \
--apiserver-advertise-address=192.168.129.140 \
--image-repository registry.aliyuncs.com/google_containers \
--service-cidr=10.96.0.0/12 \
--pod-network-cidr=10.244.0.0/16
//以下是执行完毕后输出的部分信息
Your Kubernetes control-plane has initialized successfully!
To start using your cluster, you need to run the following as a regular user
:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/
Then you can join any number of worker nodes by running the following on eac
h as root:
kubeadm join 192.168.129.140:6443 --token a8h86d.zt3nv5yvn0jl2vha \
--discovery-token-ca-cert-hash sha256:345e373e14a82caad48fb1061682b045915b2097d662336db53b6a02d1f80662
#5、配置kubectl工具
$ mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
#6、查看主节点状态
$ kubectl get node
$NAME STATUS ROLES AGE VERSION
cloudmaster NotReady master 27h v1.17.1
$ kubectl get pods -n kube-system
#7、部署flannel网络
$ kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
#若该文件拉取不到，使用如下部署文件
$ yum install vim -y
$ vim kube-flannel.yaml
kube-flannel.yaml

三、安装kubeedge集群
3.1、安装CloudCore （在cloudmaster节点操作）
安装有两种方式，一种源码编译手动安装，还有一种是使用ke提供的工具-keadm。手动安装比较繁琐，对于新手而言是一种很大的心智负担，最好大家还是都用keadm这个工具去安装，但是，这种方式安装最大的问题就是国内的墙的问题会导致很多某些资源无法下载，比如说 CRD的yaml,cloudcore启动的service，所以我会结合两者，采用半手动半工具的安装方式去完成ke的集群搭建。
#1、下载keadm
$ mkdir kubeedge
$ cd kubeedge/
$ yum install wget -y
# 快照《安装k8s》
$ wget https://github.com/kubeedge/kubeedge/releases/download/v1.5.0/keadm-v1.5.0-linux-amd64.tar.gz #失败的话建议手动安装
#解压
$ tar -zxvf keadm-v1.5.0-linux-amd64.tar.gz
$ cd keadm-v1.5.0-linux-amd64/keadm && chmod +x keadm && mv keadm /usr/local/bin
#验证keadm是否安装成功
$ keadm version
version: version.Info{Major:"1", Minor:"5", GitVersion:"v1.5.0", GitCommit:"8b0913e04ef4ef826af6715d336e23a66e3774df", GitTreeState:"clean", BuildDate:"2020-11-13T08:04:56Z", GoVersion:"go1.15", Compiler:"gc", Platform:"linux/amd64"}
#快照《安装keadm》
#2、使用keadm安装cloudcore
$ keadm init --advertise-address=192.168.129.140 --kubeedge-version=1.5.0
Kubernetes version verification passed, KubeEdge installation will start...

Usage:
keadm init [flags]
Examples:
keadm init
- This command will download and install the default version of KubeEdge cloud component
keadm init --kubeedge-version=1.5.0 --kube-config=/root/.kube/config
- kube-config is the absolute path of kubeconfig which used to secure connectivity between cloudcore and kube-apiserver
Flags:
--advertise-address string Use this key to set IPs in cloudcore's certificate SubAltNames field. eg: 10.10.102.78,10.10.102.79
--domainname string Use this key to set domain names in cloudcore's certificate SubAltNames field. eg: www.cloudcore.cn,www.kubeedge.cn
-h, --help help for init
--kube-config string Use this key to set kube-config path, eg: $HOME/.kube/config (default "/root/.kube/config")
--kubeedge-version string Use this key to download and use the required KubeEdge version
--master string Use this key to set K8s master address, eg: http://127.0.0.1:8080
--tarballpath string Use this key to set the temp directory path for KubeEdge tarball, if not exist, download it

–advertise-address=xxx.xx.xx.xx 这里的xxx.xx.xx.xx换成master机器的ip,可以是内网地址，也可以是公网ip地址，–kubeedge-version=1.5.0 意思是指定安装的ke的版本，如果你默认不指定那么keadm会自动去下载最新的版本。很遗憾，我在执行
keadm init --advertise-address=xxx.xx.xx.xx --kubeedge-version=1.5.0
命令的时候出错了，这个错的问题在于网络被墙了，特别是在公有云的虚拟机上，出现这种问题的概率特别大，这种问题咋解决，一种是翻墙翻出去，另外一种是在/etc/hosts下添加如下内容

# 配置文件

#加入集群
$ cd /etc/kubeedge/
$ keadm join --cloudcore-ipport=192.168.129.140:10000 --kubeedge-version=1.5.0 --token=
-cloudcore-ipport表示的是cloudcore的对外暴露的ip就是公网ip了，如果你是在公有云服务器上的记得打开安全组的端口
--kubeedge-version就是ke的版本
--token= 这个token是上一步集群的token
[y/N]:
# 此处输入N，checksum失败不影响配置，不必担心。选择y通过不了。
提示：如果github下载不下来就将master上的文件拷贝过来
edgecore.service
[Unit]
Description=cloudcore.service
[Service]
Type=simple
ExecStart=/etc/kubeedge/kubeedge-v1.5.0-linux-amd64/edge/edgecore --logtostderr=false --log-file=/var/log/kubeedge/edgecore.log -v=3
Restart=always
RestartSec=10
[Install]
WantedBy=multi-user.target
3.5、检查ke集群是否安装完成
[root@master kubeedge]# kubectl get node
NAME STATUS ROLES AGE VERSION
cloudmaster Ready cloudmaster 27h v1.17.1
cloudedge Ready agent,edge 4h24m v1.19.3-kubeedge-v1.5.0
四、常用指令
# 查看 systemd托管列表
$ systemctl list-unit-files
$ systemctl start cloudcore.service && systemctl enable cloudcore.service
# 查看节点状态
$ kubectl get node
$ kubectl get po -A
$ kubectl get po -n kube-system
$ kubectl get po -o wide
#查看网络状态
$ yum install net-tools -y
$ netstat -ntlp
#查看docker状态docker
$ docker images | grep kubeedge-pi-counter
# 传文件
$ scp kubeedge-pi-counter.tar 192.168.129.151:/root/
tmp目录下的文件
注意事项：
1、一般情况下，使用完成尽量挂起虚拟机，不然容器停掉，启动后node会处于not reday状态。
2、如果node处于not reday状态了，执行一下重启脚本，执行命令如下：
bash restart_kubeedge.sh
脚本内容：
#!/bin/bash
for i in `docker ps -a | awk '{print $1}' | grep -v CONT`;do docker restart $i;done
for i in `docker ps -a | awk '{print $1}' | grep -v CONT`;do docker restart $i;done
