准备三台机器（虚拟机）

  192.168.1.40 k8s-master 

  192.168.1.41 k8s-node1 

  192.168.1.42 k8s-node2 

关闭防火墙

  systemctl stop firewalld 

  systemctl disable firewalld 

  创建/etc/sysctl.d/k8s.conf文件，添加如下内容： 

  net.bridge.bridge-nf-call-ip6tables = 1 

  net.bridge.bridge-nf-call-iptables = 1 

  vm.swappiness=0 

  执行sysctl -p /etc/sysctl.d/k8s.conf使修改生效 

  删除swap 

  swapoff -a 

  vi /etc/fstab 

  注释掉如下行 

  /home/swap swap swap default 0 0 

  删除 rm /home/swap 

  禁用SELINUX： 

  setenforce 0 

  vi /etc/selinux/configSELINUX=disabled 

安装Docker（使用阿里云镜像）

  # step 1: 安装必要的一些系统工具 

  sudo yum install -y yum-utils device-mapper-persistent-data lvm2 

  # Step 2: 添加软件源信息 

  sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo 

  # Step 3: 更新并安装 Docker-CE 

  sudo yum makecache fast 

  yum install -y --setopt=obsoletes=0 \ 

  docker-ce-17.03.2.ce-1.el7.centos \ 

  docker-ce-selinux-17.03.2.ce-1.el7.centos 

  systemctl start docker 

  systemctl enable docker 

安装rpm

  yum install 
  -y socat 

  rpm -iv kubeadm-1.8.0-1.x86_64.rpm kubectl-1.8.0-1.x86_64.rpm kubelet-1.8.0-1.x86_64.rpm kubernetes-cni-0.5.1-1.x86_64.rpm 

Master初始化

  kubeadm init \ 

  --kubernetes-version=v1.8.1 \ 

  --pod-network-cidr=10.244.0.0/16 

  To start using your cluster, you need to run (as a regular user): 

  mkdir -p $HOME/.kube 

  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config 

  sudo chown $(id -u):$(id -g) $HOME/.kube/config 

node节点加入集群

  kubeadm join --token 06c7f3.b3fcabe04b38dc00 192.168.1.40:6443 --discovery-token-ca-cert-hash sha256:2163f86ffd232335afd3d7b6899753953ab4c348428667ffe7959bbf0082af52
