master：192.168.73.152
node1 : 192.168.73.153
node2 : 192.168.73.155 

1、关闭firewalld和selinux（所有主机）
vi /etc/selinux/config
systemctl stop firewalld
 systemctl disable firewalld

2、配置解析/etc/hosts（所有主机）
vim /etc/hosts
192.168.73.100 kubernetes
192.168.73.101 kubernetes-node1
192.168.73.102 kubernetes-node2
192.168.73.152 kubernetes
192.168.73.153 kubernetes-node1
192.168.73.155 kubernetes-node2

3、添加内核参数文件 /etc/sysctl.d/k8s.conf（所有主机）
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward = 1
vm.swappiness = 0

4、执行命令（所有主机）
modprobe br_netfilter
sysctl -p /etc/sysctl.d/k8s.conf

5、安装docker（所有主机）
yum install -y yum-utils device-mapper-persistent-data lvm2
wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker.repo
查看版本
 yum list docker-ce.x86_64  --showduplicates |sort -r

安装指定的docker（所有主机）
yum makecache fast
yum install docker-ce-18.06.1.ce-3.el7   -y

查看docker版本
docker -v

6、生成kubernetes的yum仓库配置文件/etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
gpgcheck=0
enabled=1

安装（所有主机）
yum makecache fast
yum install -y kubelet kubeadm kubectl

7、关闭swap（所有主机）
swapoff  -a
sysctl -p /etc/sysctl.d/k8s.conf 
注释掉/etc/fstab中的swap条目
 mount -a
echo "KUBELET_EXTRA_ARGS=--fail-swap-on=false" > /etc/sysconfig/kubelet

8、 使用kubeadm init初始化集群，kubeadm version看kubernetes的版本（master上）
systemctl restart docker
systemctl enable kubelet.service docker
kubeadm version    
kubeadm init --kubernetes-version=v1.13.3 --pod-network-cidr=10.244.0.0/16 --service-cidr=10.96.0.0/12 --ignore-preflight-errors=Swap

加速（所有主机）
curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://45203393.m.daocloud.io
systemctl daemon-reload
systemctl restart docker

 
相关的软件的版本按init初始化出来的版本更改（所有主机）
vim k8s.sh

    docker rmi k8s.gcr.io/coredns:1.2.6

chmod 755 k8s.sh 
./k8s.sh 

9、重新初始化，最后一行要保存（master上）
kubeadm init --kubernetes-version=v1.13.3 --pod-network-cidr=10.244.0.0/16 --service-cidr=10.96.0.0/12 --ignore-preflight-errors=Swap

Your Kubernetes master has initialized successfully!

To start using your cluster, you need to run the following 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

You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
  https://kubernetes.io/docs/concepts/cluster-administration/addons/

You can now join any number of machines by running the following on each node
as root:

  kubeadm join 192.168.73.152:6443 --token l9jvft.bspa25s561skhcuq --discovery-token-ca-cert-hash sha256:b0a0ff52a16e55488876e2144801e4acc80bcdc948f3aab09924e9c18f6c8360
