1.docker安装

配置源

wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker- ce.repo -O /etc/yum.repos.d/docker-ce.repo

# yum install --setopt=obsoletes=0 docker-ce-18.06.3.ce-3.el7 -y  //指定版本

 yum install docker-ce  //选择其一进行安装

添加配置文件

cat /etc/docker/daemon.json

{ 
    "exec-opts": ["native.cgroupdriver=systemd"], 
    "registry-mirrors": ["https://kn0t2bca.mirror.aliyuncs.com"] 
}

 

2.cri-dockerd安装

 yum localinstall cri-dockerd-0.2.3-3.el7.x86_64.rpm

 修改配置文件/usr/lib/systemd/system/cri-docker.service

ExecStart=/usr/bin/cri-dockerd --network-plugin=cni --pod-infra-container-image=registry.aliyuncs.com/google_containers/pause:3.7

 启动cri-docker

systemctl daemon-reload

systemctl enable cri-docker --now

集群初始化，在master节点上做

kubeadm init --kubernetes-version=v1.24.2 --pod-network-cidr=10.224.0.0/16 --apiserver-advertise-address=192.168.40.132 --cri-socket unix:///var/run/cri-dockerd.sock --image-repository registry.aliyuncs.com/google_containers

然后在node1和node2上面做

  kubeadm join 192.168.40.132:6443 --token 56622b.1i9erjpt334z56eh --discovery-token-ca-cert-hash sha256:0e049eb92a04b40d0051291419c01645a029e3795730bb49a67dc810ec5d6d25  --cri-socket unix:///var/run/cri-dockerd.sock

 

 3.安装flannel

wget http://down.i4t.com/k8s1.24/kube-flannel.yml

kubectl apply -f kube-flannel.yml
