1、kubectl已经安装，当前安装的版本是1.15.1rpm -qa|grep kubectl
3、初始化主节点，生成配置文件kubeadm config print init-defaults > kubeadm-config.yaml
5、networking改动较大，后面也要增加些内容networking: podSubnet: "10.244.0.0/16" serviceSubnet: 10.96.0.0/12scheduler: {}---apiVersion: kubeproxy.config.k8s.io/v1alpha1kind: KubeProxyConfigurationfeatureGates:SupportIPVSProxyMode: truemode: ipvs
7、初始化成功之后会出现node节点加入master的命令，如果初始化失败就要修改kubeadm-config.yaml重新初始化
