安装步骤

1.关闭防火强和selinux

systemctl stop firewalld
systemctl disable firewalld  //关闭防火墙 
setenforce 0                 //关闭selinux

同时修改文件vim /etc/selinux/config

vim /etc/selinux/config
SELINUX=disabled
SELINUXTYPE=targeted

修改后如下图所示：

2.禁用swap以及修改内核参数和模块

swapoff -a                                       //禁用swap
net.bridge.bridge-nf-call-ip6tables = 1          
net.bridge.bridge-nf-call-iptables = 1           //修改文件vim /etc/sysctl.d/k8s.conf

sysctl --system

modprobe br_netfilter         //执行命令

3.安装docker

yum -y install yum-utils device-mapper-persistent-data lvm2
yum-config-manager -y --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum -y install docker-ce-18.06.3.ce-3.el7 docker-ce-cli-18.06.3.ce-3.el7 containerd.io
systemctl start docker
systemctl enable docker                //1021041215 安装docker


docker version

  OS/Arch:          linux/amd64
  Experimental:     false               //安装后执行docker version

安装完成

4.安装Kubernetes组件

[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.ali
//修改文件vim /etc/yum.repos.d/kubernetes.repo

yum -y install kubelet-1.13* kubeadm-1.13* kubectl-1.13*
systemctl start kubelet
systemctl enable kubelet
//执行命令

5.下载Kubernetes镜像，并打标签

docker pull mirrorgooglecontainers/kube-apiserver:v1.13.3

docker pull mirrorgooglecontainers/kube-controller-manager:v1.13.3

docker pull mirrorgooglecontainers/kube-scheduler:v1.13.3

docker pull mirrorgooglecontainers/kube-proxy:v1.13.3

docker pull mirrorgooglecontainers/pause:3.1

docker pull mirrorgooglecontainers/etcd:3.2.24

docker pull coredns/coredns:1.2.6
 
// 打标签
docker tag mirrorgooglecontainers/kube-apiserver:v1.13.3 k8s.gcr.io/kube-apiserver:v1.13.3

docker tag mirrorgooglecontainers/kube-controller-manager:v1.13.3 k8s.gcr.io/kube-controller-manager:v1.13.3

docker tag mirrorgooglecontainers/kube-scheduler:v1.13.3 k8s.gcr.io/kube-scheduler:v1.13.3

docker tag mirrorgooglecontainers/kube-proxy:v1.13.3 k8s.gcr.io/kube-proxy:v1.13.3

docker tag mirrorgooglecontainers/pause:3.1 k8s.gcr.io/pause:3.1

docker tag mirrorgooglecontainers/etcd:3.2.24 k8s.gcr.io/etcd:3.2.24

docker tag coredns/coredns:1.2.6 k8s.gcr.io/coredns:1.2.6

6.初始化

kubeadm init --kubernetes-version=v1.13.3 --pod-network-cidr=10.100.0.0/16

再根据提示做如下操作

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
kubectl apply -f https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version

成功后执行以下命令

kubectl get pods --all-namespaces

经过以上操作，安装成功

单机Kubernetes安装
