一、系统配置
1、环境信息
云主机A：IP：164.52.44.42  配置：4u4g  主机名：master  主节点
云主机B：IP：164.52.44.43  配置：4u4g  主机名：node    子节点

2、(双节点)配置hosts解析,添加如下信息
[root@master ~]# vim /etc/hosts
164.52.44.43    node
164.52.44.42    master

3、(双节点)关闭防火墙
systemctl stop firewalld
systemctl disable firewalld

4、(双节点)关闭selinux防火墙
vim /etc/sysconfig/selinux
#SELINUX修改为disabled
SELINUX=disabled 

5、(双节点)安装系统常用工具
yum -y install curl wget net-tools vim lrzsz

6、(双节点)安装基本服务
yum -y install yum-utils device-mapper-persistent-data lvm2

二、(双节点)安装docker
1、下载docker源到yum仓库
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

2、(双节点)安装docker-ce
yum install docker-ce -y

3、(双节点)开机自启动，和启动docker
systemctl start docker
systemctl enable docker
三、(双节点)安装k8s
1、添加k8s的yum源

cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF

2、(双节点)安装k8s管理工具
yum -y install kubelet-1.13.1 kubeadm-1.13.1 kubectl-1.13.1 --disableexcludes=kubernetes

3、(主节点)下载k8s使用的镜像

docker pull mirrorgooglecontainers/kube-apiserver-amd64:v1.13.1
docker pull mirrorgooglecontainers/kube-controller-manager-amd64:v1.13.1
docker pull mirrorgooglecontainers/kube-scheduler-amd64:v1.13.1
docker pull mirrorgooglecontainers/kube-proxy-amd64:v1.13.1
docker pull mirrorgooglecontainers/pause:3.1
docker pull mirrorgooglecontainers/etcd-amd64:3.2.24
docker pull coredns/coredns:1.2.6
docker tag mirrorgooglecontainers/kube-controller-manager-amd64:v1.13.1 k8s.gcr.io/kube-controller-manager:v1.13.1
docker tag mirrorgooglecontainers/kube-scheduler-amd64:v1.13.1 k8s.gcr.io/kube-scheduler:v1.13.1
docker tag mirrorgooglecontainers/kube-apiserver-amd64:v1.13.1 k8s.gcr.io/kube-apiserver:v1.13.1
docker tag mirrorgooglecontainers/kube-proxy-amd64:v1.13.1 k8s.gcr.io/kube-proxy:v1.13.1
docker tag mirrorgooglecontainers/pause:3.1 k8s.gcr.io/pause:3.1
docker tag mirrorgooglecontainers/etcd-amd64:3.2.24 k8s.gcr.io/etcd:3.2.24
docker tag coredns/coredns:1.2.6 k8s.gcr.io/coredns:1.2.6

4、(主节点)关闭swap分区 1,为临时；2,永久
(1)、swapoff -a
(2)、vim /etc/sysconfig/kubelet 
KUBELET_EXTRA_ARGS="--fail-swap-on=false"

5、(主节点)初始化集群，指定版本和设置网络段
kubeadm init --kubernetes-version=1.13.1 --pod-network-cidr=10.244.0.0/16

！！看到以下信息即为正常

kubeadm join 164.52.44.42:6443 --token na5io2.rcducfd1bf889rzy --discovery-token-ca-cert-hash sha256:ddd3923e15175c389f92ad52070bd383648afb850c661973463b2fc60c504bd2 

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

6、(子节点)加入到主节点

kubeadm join 10.1.65.131:6443 --token na5io2.rcducfd1bf889rzy --discovery-token-ca-cert-hash sha256:ddd3923e15175c389f92ad52070bd383648afb850c661973463b2fc60c504bd2

(主节点)查看：

[root@master ~]# kubectl get nodes

7、(主节点)配置flannel网络
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

8、(主节点)查看状态都ready即正常
kubectl get nodes
#可能问题，服务在ContainerCreating或是pending
使用命令：kubectl get pods -n kube-system
kubectl describe pod ($name) --namespace=kube-system

四、(主节点)安装dashboard

1、(主节点)配置dashboard

vim kubernetes-dashboard.yml
