sudo systemctl restart docker
其他设置
#每台主机都需要设置
swapoff -a
sed -ri 's/.*swap.*/#&/' /etc/fstab
sudo systemctl stop ufw
sudo systemctl disable ufw
cat <k8s的安装
kubeadm引导安装
#安装golang并添加环境变量
sudo wget https://dl.google.com/go/go1.18.3.linux-amd64.tar.gz
sudo tar -zxvf go1.18.3.linux-amd64.tar.gz -C /usr/local/

master初始化
systemctl enable --now kubelet
#查看有哪些参数需要指定
kubeadm init -h
# 一般指定以下参数即可
#默认镜像为Google无情况下会导致拉取失败，更换为阿里云的镜像
#指定网段以及kubernetes版本
kubeadm init \
--apiserver-advertise-address=192.168.0.85 \

#根据提醒进行操作
#创建文件夹进行配置
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config

网络插件的安装(calico)
curl https://docs.projectcalico.org/archive/v3.21/manifests/calico.yaml -O
kubectl apply -f calico.yaml
二进制安装参照kubernets官方文档
kubeedge安装
云端环境
#需要四个文件
#checksum_kubeedge-v1.8.2-linux-amd64.tar.gz.txt
#keadm-v1.8.2-linux-amd64.tar.gz
#kubeedge-v1.8.2-linux-amd64.tar.gz
#v1.8.2.tar.gz
tar -zxvf keadm-v1.8.2-linux-amd64.tar.gz
cd /etc/kubeedge/
cp ~/ke/checksum_kubeedge-v1.8.2-linux-amd64.tar.gz.txt .
cd ~/ke
tar -zxvf v1.8.2.tar.gz
cd kubeedge-1.8.2/build/tools
cp cloudcore.service edgecore.service /etc/kubeedge
cd ..
cp -r crds/ /etc/kubeedge
keadm init --kubeedge-version=1.8.2 --advertise-address=123.249.112.195
ps aux | grep 'cloudcore'
netstat -nplt
值得注意的是cloudcore有时候不会启动，当你发现你的edgecore处于（code=exited,status=255）时.查看10000和10002端口是否有cloudcore使用
#设置自动启动
sudo cp /etc/kubeedge/cloudcore.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl start cloudcore.service
sudo systemctl enable cloudcore.service
边缘端环境
vim /etc/hosts
123.249.112.195 master
scp root@master:/usr/local/bin/keadm /usr/local/bin/
scp -r root@master:/etc/kubeedge /etc/
#在master上 keadm gettoken获得令牌 有时间限制
keadm join --cloudcore-ipport=123.249.112.195:10000 --kubeedge-version=1.8.2 --token=d4143460867e37a127f4c252650cd024b376e0b5df5e683837914a8a6cdc228a.eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE2Nzc5NjUwOTN9.1WfulQG
systemctl status edgecore.service
#当你的edgecore有任何问题的时候，你都可以使用以下命令来打印日志
journalctl -u edgecore.service
# 你有可能会遇见驱动不一致的问题，一般在daemon.json里面修改"exec-opts": ["native.cgroupdriver=cgroupfs"]就能得到解决
查看node情况
kubectl get nodes -o wide
