k8s安装：
cat /etc/hosts
127.0.0.1 localhost
10.26.3.182 kuber-node1
10.26.3.184 kuber-master
1、关闭防火墙
systemctl stop firewalld.service
2、关闭selinux
setenforce 0
3.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
net.ipv4.ip_forward = 1
4.
cat > /etc/sysconfig/modules/ipvs.modules <<EOF
#!/bin/bash
modprobe -- ip_vs
modprobe -- ip_vs_rr
modprobe -- ip_vs_wrr
modprobe -- ip_vs_sh
modprobe -- nf_conntrack_ipv4
EOF
chmod 755 /etc/sysconfig/modules/ipvs.modules && bash /etc/sysconfig/modules/ipvs.modules && lsmod | grep -e ip_vs -e nf_conntrack_ipv4
5.安装docker的yum源:
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
yum makecache fast
yum install -y --setopt=obsoletes=0 docker-ce-18.06.1.ce-3.el7
systemctl start docker
systemctl enable docker
6.
cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=http://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=http://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg http://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF
7.安装kubelet kubeadm klubectl 【master和node都需要执行】
yum makecache fast
yum install -y kubelet kubeadm kubectl
systemctl enable kubelet.service
8.vi push.sh
主节点初始化
初始化的时候，需要×××下载镜像，可以使用下面脚本下载镜像
echo ""
echo "=========================================================="
echo "Pull Kubernetes v1.14.1 Images from aliyuncs.com ......"
echo "=========================================================="
echo ""
MY_REGISTRY=registry.cn-hangzhou.aliyuncs.com/openthings
## 拉取镜像
docker pull ${MY_REGISTRY}/k8s-gcr-io-kube-apiserver:v1.14.1
docker pull ${MY_REGISTRY}/k8s-gcr-io-kube-controller-manager:v1.14.1

docker pull ${MY_REGISTRY}/k8s-gcr-io-pause:3.1
docker pull ${MY_REGISTRY}/k8s-gcr-io-coredns:1.3.1
## 添加Tag
docker tag ${MY_REGISTRY}/k8s-gcr-io-kube-apiserver:v1.14.1 k8s.gcr.io/kube-apiserver:v1.14.1
docker tag ${MY_REGISTRY}/k8s-gcr-io-kube-scheduler:v1.14.1 k8s.gcr.io/kube-scheduler:v1.14.1

9.我们现在要把kuber-node1 添加进来了。
在kuber-node1上输入以下命令
每个token只有24小时的有效期，如果没有有效的token，可以使用如下命令创建
kubeadm token create
获取token：
master:kubeadm token list 2ubuk7.357s4vsfxdyqw1kz
Kubernetes认证的SHA256加密字符串是多少，这里可以使用这个命令查看到：openssl x509 -pubkey -in /etc/kubernetes/pki/ca.crt | openssl rsa -pubin -outform der 2>/dev/null | openssl dgst -sha256 -hex | sed ‘s/^.* //‘
9725bcd4fc6bc7bb0dfaf7781da359eb607deb2f642cf2bfdfb5d1f951fa75ea
[root@kuber-node1 ~]# kubeadm join 139.159.27.18:6443 --token 2ubuk7.357s4vsfxdyqw1kz--discovery-token-ca-cert-hash sha256:9725bcd4fc6bc7bb0dfaf7781da359eb607deb2f642cf2bfdfb5d1f951fa75ea
