构建完成后生成cri-dockerd命令
接下来执行cri-dockerd命令的安装及环境配置命令 install -o root -g root -m 0755 cri-dockerd /usr/bin/cri-dockerd cp -a packaging/systemd/* /etc/systemd/system systemctl daemon-reload systemctl enable cri-docker.service systemctl enable --now cri-docker.socket
4、 安装kubeadm、kubelet、kubectl（每个节点都执行）
添加阿里云yum源 cat > /etc/yum.repos.d/kubernetes.repo << EOF [kubernetes] name=kubernetes baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64 enabled=1 gpgcheck=0 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 EOF 检查yum源是不是有跟kube相关的安装源 # yum list | grep kube 指定版本安装 yum install kubeadm kubectl kubelet -y
设置开机自启 systemctl enable kubelet && systemctl start kubelet
也可执行 yum list kubeadm kubelet kubectl --showduplicates | sort -r 按照输出的列表项安装特定版本.
拉取k8s指定版本的镜像 kubeadm config images pull --cri-socket unix:///var/run/cri-dockerd.sock --image-repository registry.aliyuncs.com/google_containers
master节点执行如下命令安装k8s kubeadm init --kubernetes-version=v1.24.3 \ --pod-network-cidr=10.224.0.0/16 \ --apiserver-advertise-address=192.168.247.101 \ --cri-socket unix:///var/run/cri-dockerd.sock \ --image-repository registry.aliyuncs.com/google_containers
查看 /var/log/messages 日志可以找到相关报错
该问题可能属于k8s代码问题，解决办法使用国内源下载该版本镜像，然后重新打tag docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.6 docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.6 k8s.gcr.io/pause:3.6
重新执行执行初始化命令，即可成功 # kubeadm init --kubernetes-version=v1.24.3 --pod-network-cidr=10.224.0.0/16 --apiserver-advertise-address=192.168.247.101 --cri-socket unix:///var/run/cri-dockerd.sock --image-repository registry.aliyuncs.com/google_containers
接下来在worker节点上执行相关的操作，worker节点与master节点的操作步骤的唯一区别是：master节点执行kubeadm init操作，woker节点执行kubeadm join操作， 因此上面的步骤除了kubeadm init步骤之外，其他所有的步骤woker节点同样也需要执行。 执行kubeadm init 成功之后输出的 最后一行kubeadm join 命令 kubeadm config images pull --cri-socket unix:///var/run/cri-dockerd.sock --image-repository registry.aliyuncs.com/google_containers kubeadm join 192.168.247.101:6443 --token o4zf8w.rw20jhmskiyk0ton --discovery-token-ca-cert-hash sha256:376e215a51620ac699223ac80cbd57f2adcf46b2c0eef0a7dfd003a55f7dac78 --cri-socket unix:///var/run/cri-dockerd.sock
