前置准备准备两台服务器，一台做master，一台做slave，每台机器内存要大于2G。在命令行通过ufw等防火墙工具开放相关端口，如果使用的是云服务则应去控制台页面进行设置。确保每台机器已经安装了容器运行时，如docker。 1. 安装 kubeadm、kubelet 和 kubectl123456789101112131415cat <<EOF | sudo tee /etc/yum.repos.d/kubernetes.repo[kubernetes]name=Kubernetesbaseurl=https://pkgs.k8s.io/core:/stable:/v1.26/rpm/enabled=1gpgcheck=1gpgkey=https://pkgs.k8s.io/core:/stable:/v1.26/rpm/repodata/repomd.xml.keyexclude=kubelet kubeadm kubectl cri-tools kubernetes-cniEOF# 将 SELinux 设置为 permissive 模式（相当于将其禁用）sud ...
