简介

一.确认kubectl命令是否正常运行

二.确认etcd安装是否正常运行

三.确认kube-apiserver,kube-controller-manager,kube-scheduler安装是否正常

四.配置apiserver和kubelet的访问授权

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  annotations:
    rbac.authorization.kubernetes.io/autoupdate: "true"
  labels:
    kubernetes.io/bootstrapping: rbac-defaults
  name: system:kube-apiserver-to-kubelet
rules:
  - apiGroups:
      - ""
    resources:
      - nodes/proxy
      - nodes/stats
      - nodes/log
      - nodes/spec
      - nodes/metrics
      - pods/log
    verbs:
      - "*"
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: system:kube-apiserver
  namespace: ""
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: system:kube-apiserver-to-kubelet
subjects:
  - apiGroup: rbac.authorization.k8s.io
    kind: User
    name: kubernetes

五.master端安装脚本

4.1.安装master端所需文件

服务启动脚本：
/usr/lib/systemd/system/kube-apiserver.service
/usr/lib/systemd/system/kube-controller-manager.service
/usr/lib/systemd/system/kube-scheduler.service

4.2.master快捷安装脚本

#!/bin/sh
#创建目录
mkdir -p /opt/kubernetes/ssl /opt/kubernetes/conf /opt/kubernetes/logs /opt/kubernetes/bin

#将第一章第二章准备好的文件拷贝到对应目录
cp cert/* /opt/kubernetes/ssl/
cp conf/* /opt/kubernetes/conf/
cp services/* /usr/lib/systemd/system/
cp token.csv /opt/kubernetes/conf/
cp kubeconfig/* /opt/kubernetes/conf/
cp ../ca/* /opt/kubernetes/ssl/
tar zxvf kubernetes-server-linux-amd64.tar.gz
cp kubernetes/server/bin/kube-apiserver kubernetes/server/bin/kube-controller-manager kubernetes/server/bin/kube-scheduler /opt/kubernetes/bin/

#配置开机启动
systemctl daemon-reload
systemctl enable kube-apiserver
systemctl enable kube-controller-manager
systemctl enable kube-scheduler

systemctl start kube-apiserver
sleep 3
systemctl start kube-controller-manager
sleep 3
systemctl start kube-scheduler
