mac上先安装好centos8系统，网上有修改好能够在mac的vmware上安装的镜像
Docke Docke r安装 (master and node)
安装必要的一些系统工具
yum install -y yum-utils device-mapper-persistent-data lvm2
设置stable镜像aliyun aliyun aliyun仓库
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum makecache fast # 更新yum软件包索引
yum list docker-ce --showduplicates | sort -r #查看版本
yum remove podman -y #centos8才需要
yum install docker-ce docker-ce-cli containerd.io --allowerasing
systemctl start docker
systemctl enable docker -- now
设置 Docker 镜像加速器
修改docker 配置以适应kubelet
vi /etc/docker/daemon.json
{
"registry-mirrors": ["https://registry.cn-hangzhou.aliyuncs.com"],
"exec-opts": ["native.cgroupdriver=systemd"]
}
systemctl daemon-reload
systemctl restart docker
关闭防火墙
systemctl disable firewalld
systemctl stop firewalld
关闭 Swap
swapoff -a
sed -i 's/.*swap.*/#&/' /etc/fstab
关闭selinux
vim /etc/selinux/config 如下
SELINUX=disabled # 修改此项
setenforce 0
vi /etc/sysctl.d/k8s.conf 文件，添加如下内容：
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward = 1
#执行如下命令使修改生效：
modprobe br_netfilter
sysctl -p /etc/sysctl.d/k8s.conf
加载ipvs模块
modprobe -- ip_vs
modprobe -- ip_vs_rr
modprobe -- ip_vs_wrr
modprobe -- ip_vs_sh
modprobe -- nf_conntrack_ipv4
lsmod | grep ip_vs
lsmod | grep nf_conntrack_ipv4
yum install -y ipvsadm ipset
kubeadm、kubelet、kubectl安装
vi /etc/yum.repos.d/kubernetes.repo
[kubernetes] name=Kubernetes baseurl=http://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-aarch64/ enabled=1 gpgcheck=1 repo_gpgcheck=0 gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
yum list kubeadm --showduplicates |sort -r
卸载：yum remove kubeadm.x86_64 kubectl.x86_64 kubelet.x86_64 -y
方式1：yum install kubeadm kubectl kubelet -y
方式2：yum install kubeadm-1.21.5 kubectl-1.21.5 kubelet-1.21.5 -y
节点对应的位置即可使用kubectl命令行工具了
kubectl version
启动kubelet
systemctl daemon-reload
systemctl start kubelet.service
systemctl enable kubelet.service
systemctl status kubelet.service
systemctl enable docker.service
systemctl enable kubelet.service
#初始化
kubeadm init --image-repository registry.aliyuncs.com/google_containers --kubernetes-version=v1.23.1 --pod-network-cidr=10.10.0.0/16 --service-cidr=10.20.0.0/16 --apiserver-advertise-address=192.168.90.135
下面的命令是配置如何使用kubectl访问集群的方式：
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
kubectl get all -A
kubectl apply -f kube-flannel.yaml
kubectl get ds -l app=flannel -n kube-system
kubectl describe node caomj |grep Taint
kubectl taint nodes caomj node-role.kubernetes.io/master-
kubectl describe configmap kube-proxy -n kube-system
kubectl edit configmap kube-proxy -n kube-system
mode: "ipvs"
k delete pod *1
本地镜像文件dashboard.yaml

先下载docker镜像
docker pull kubernetesui/dashboard-arm64:v2.0.5

kubectl get svc -n kubernetes-dashboard
openssl genrsa -out dashboard.key 2048
openssl req -new -out dashboard.csr -key dashboard.key -subj '/CN=192.168.90.135'
openssl x509 -days 3650 -req -in dashboard.csr -signkey dashboard.key -out dashboard.crt
kubectl create secret generic kubernetes-dashboard-certs --from-file=/soft/dashboard.key --from-file=/soft/dashboard.crt -n kubernetes-dashboard
https://192.168.90.134:31234
kubectl get pods --all-namespaces -o wide
vim /usr/lib/systemd/system/docker.service [Service] Type=notify ExecStartPost=/sbin/iptables -I FORWARD -s 0.0.0.0/0 -j ACCEPT ##加入这句
