1 系统准备
查看系统版本
[root@localhost]# cat /etc/centos-release CentOS Linux release 8.1.1911 (Core)
修改主机名
hostnamectl set-hostname master01
我在两个服务器测试的，一个是我阿里云的服务器，这个是8.1的系统，另一个是本地虚拟机是7.4的系统，基本差不多操作
自己设置好ip
改名字不用说了吧
添加阿里源
[root@master ~]# rm -rfv /etc/yum.repos.d/*
[root@master ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-8.repo
配置主机名
[root@master ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.0.149 master
ip配置信息
cd /etc/sysconfig/network-scripts下面的配置，我的是ifcfg-ens33
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=d06d07c2-9167-4ada-addb-b05c2669e24b
DEVICE=ens33
IPADDR=192.168.8.10
NETMASK=255.255.255.0
GATEWAY=192.168.8.2
DNS1=114.114.114.114
ONBOOT=yes
保存之后重启netwok服务
4、重启网卡服务
service network restart 或
关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
关闭swap，注释swap分区
[root@master ~]# swapoff -a [root@master ~]# cat /etc/fstab #/dev/mapper/cl-swap swap swap defaults 0 0
配置内核参数，将桥接的IPv4流量传递到iptables的链
[root@master ~]# cat > /etc/sysctl.d/k8s.conf <<EOF net.bridge.bridge-nf-call-ip6tables = 1 net.bridge.bridge-nf-call-iptables = 1 EOF sysctl --system
2 安装常用包
[root@master ~]# yum install vim bash-completion net-tools gcc -y
3 使用aliyun源安装docker-ce
安装docker依赖的软件包
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
设置yum镜像源为阿里镜像源，加快安装速度
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
如果用官方的docker镜像源，安装很慢，很可能会安装失败。官方镜像源为：https://download.docker.com/linux/centos/docker-ce.repo ，不建方使用官方镜像源。
查看所有仓库中所有docker版本，并选择特定版本安装
yum list docker-ce --showduplicates | sort -r
[root@master ~]# yum -y install docker-ce
#指定版本号
sudo yum install docker-ce-19.03.6
安装docker-ce如果出现以下错
[root@master ~]# yum -y install docker-ce Error: Problem: package docker-ce-3:19.03.8-3.el7.x86_64 requires containerd.io >= 1.2.2-3, but none of the providers can be installed - cannot install the best candidate for the job - package containerd.io-1.2.10-3.2.el7.x86_64 is excluded - package containerd.io-1.2.13-3.1.el7.x86_64 is excluded - package containerd.io-1.2.2-3.3.el7.x86_64 is excluded - package containerd.io-1.2.2-3.el7.x86_64 is excluded - package containerd.io-1.2.4-3.1.el7.x86_64 is excluded - package containerd.io-1.2.5-3.1.el7.x86_64 is excluded - package containerd.io-1.2.6-3.3.el7.x86_64 is excluded (try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
解决方法
[root@master ~]# wget https://download.docker.com/linux/centos/7/x86_64/edge/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm [root@master ~]# yum install containerd.io-1.2.6-3.3.el7.x86_64.rpm
这个时候可能还是下载不下来，可以自己去百度上下载下来然后使用然后再安装docker-ce即可成功
添加aliyundocker仓库加速器
[root@master ~]# mkdir -p /etc/docker [root@master ~]# tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://fl791z1h.mirror.aliyuncs.com"] } EOF [root@master01 ~]# systemctl daemon-reload [root@master01 ~]# systemctl restart docker
4 安装kubectl、kubelet、kubeadm
添加阿里kubernetes源
[root@master ~]# 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
安装
[root@master01 ~]# yum install kubectl kubelet kubeadm 或者指定版本 yum install kubectl-1.18.0 kubelet-1.18.0 kubeadm-1.18.0 [root@master01 ~]# systemctl enable kubelet
5 初始化k8s集群
[root@master ~]# kubeadm init --kubernetes-version=1.18.0 \ --apiserver-advertise-address=192.168.0.149 \ --image-repository registry.aliyuncs.com/google_containers \ --service-cidr=10.10.0.0/16 --pod-network-cidr=10.122.0.0/16
POD的网段为: 10.122.0.0/16， api server地址就是master本机IP。
这一步很关键，由于kubeadm 默认从官网k8s.grc.io下载所需镜像，国内无法访问，因此需要通过–image-repository指定阿里云镜像仓库地址。
集群初始化成功后返回如下信息：
[root@master k8s]# kubeadm init --kubernetes-version=1.18.0 --apiserver-advertise-address=172.25.10.23 --image-repository registry.aliyuncs.com/google_containers --service-cidr=10.10.0.0/16 --pod-network-cidr=10.122.0.0/16 W1126 17:36:14.148469 15643 configset.go:202] WARNING: kubeadm cannot validate component configs for API groups [kubelet.config.k8s.io kubeproxy.config.k8s.io] [init] Using Kubernetes version: v1.18.0 [preflight] Running pre-flight checks [WARNING Service-Docker]: docker service is not enabled, please run 'systemctl enable docker.service' [WARNING IsDockerSystemdCheck]: detected "cgroupfs" as the Docker cgroup driver.

记录生成的最后部分内容，此内容需要在其它节点加入Kubernetes集群时执行。
根据提示创建kubectl
[root@master ~]# mkdir -p $HOME/.kube [root@master ~]# sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config [root@master ~]# sudo chown $(id -u):$(id -g) $HOME/.kube/config
执行下面命令，使kubectl可以自动补充
[root@master ~]# source <(kubectl completion bash)
查看节点，pod
[root@master k8s]# kubectl get node NAME STATUS ROLES AGE VERSION master NotReady master 6m55s v1.18.0 [root@master k8s]# kubectl get pod --all-namespaces NAMESPACE NAME READY STATUS RESTARTS AGE kube-system calico-kube-controllers-8586758878-79p52 0/1 Pending 0 19s kube-system calico-node-2xxg5 0/1 Init:0/3 0 19s kube-system coredns-7ff77c879f-l6nvg 0/1 Pending 0 7m21s kube-system coredns-7ff77c879f-q6j94 0/1 Pending 0 7m21s kube-system etcd-master 1/1 Running 0 7m31s kube-system kube-apiserver-master 1/1 Running 0 7m31s kube-system kube-controller-manager-master 1/1 Running 0 7m31s kube-system kube-proxy-6md54 1/1 Running 0 7m21s kube-system kube-scheduler-master 1/1 Running 0 7m31s
node节点为NotReady，因为corednspod没有启动，缺少网络pod
6 安装calico网络（此处使用calico，不使用flannel，flannel多次封包解包占用资源较多）
[root@master ~]# kubectl apply -f https://docs.projectcalico.org/manifests/calico.yaml configmap/calico-config created customresourcedefinition.apiextensions.k8s.io/bgpconfigurations.crd.projectcalico.org created customresourcedefinition.apiextensions.k8s.io/bgppeers.crd.projectcalico.org created customresourcedefinition.apiextensions.k8s.io/blockaffinities.crd.projectcalico.org created customresourcedefinition.apiextensions.k8s.io/clusterinformations.crd.projectcalico.org created customresourcedefinition.apiextensions.k8s.io/felixconfigurations.crd.projectcalico.org created customresourcedefinition.apiextensions.k8s.io/globalnetworkpolicies.crd.projectcalico.org created customresourcedefinition.apiextensions.k8s.io/globalnetworksets.crd.projectcalico.org created customresourcedefinition.apiextensions.k8s.io/hostendpoints.crd.projectcalico.org created customresourcedefinition.apiextensions.k8s.io/ipamblocks.crd.projectcalico.org created customresourcedefinition.apiextensions.k8s.io/ipamconfigs.crd.projectcalico.org created customresourcedefinition.apiextensions.k8s.io/ipamhandles.crd.projectcalico.org created customresourcedefinition.apiextensions.k8s.io/ippools.crd.projectcalico.org created customresourcedefinition.apiextensions.k8s.io/networkpolicies.crd.projectcalico.org created customresourcedefinition.apiextensions.k8s.io/networksets.crd.projectcalico.org created clusterrole.rbac.authorization.k8s.io/calico-kube-controllers created clusterrolebinding.rbac.authorization.k8s.io/calico-kube-controllers created clusterrole.rbac.authorization.k8s.io/calico-node created clusterrolebinding.rbac.authorization.k8s.io/calico-node created daemonset.apps/calico-node created serviceaccount/calico-node created deployment.apps/calico-kube-controllers created serviceaccount/calico-kube-controllers created
查看pod和node
[root@master k8s]# kubectl get pod --all-namespaces NAMESPACE NAME READY STATUS RESTARTS AGE kube-system calico-kube-controllers-8586758878-79p52 1/1 Running 0 11m kube-system calico-node-2xxg5 1/1 Running 0 11m kube-system coredns-7ff77c879f-l6nvg 1/1 Running 0 18m kube-system coredns-7ff77c879f-q6j94 1/1 Running 0 18m kube-system etcd-master 1/1 Running 0 19m kube-system kube-apiserver-master 1/1 Running 0 19m kube-system kube-controller-manager-master 1/1 Running 0 19m kube-system kube-proxy-6md54 1/1 Running 0 18m kube-system kube-scheduler-master 1/1 Running 0 19m kubernetes-dashboard dashboard-metrics-scraper-dc6947fbf-gqcdh 1/1 Running 0 8m12s kubernetes-dashboard kubernetes-dashboard-5d4dc8b976-kxz6j 1/1 Running 0 8m12s [root@master k8s]# kubectl get svc -n kubernetes-dashboard NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE dashboard-metrics-scraper NodePort 10.10.197.176 <none> 8000:30572/TCP 8m22s kubernetes-dashboard ClusterIP 10.10.7.126 <none> 443/TCP 8m22s
此时集群状态正常
7 安装kubernetes-dashboard
官方部署dashboard的服务没使用nodeport，将yaml文件下载到本地，在service里添加nodeport（或者自行去网上下载此文件）
[root@master ~]# wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-rc7/aio/deploy/recommended.yaml [root@master ~]# vim recommended.yaml kind: Service apiVersion: v1 metadata: labels: k8s-app: kubernetes-dashboard name: kubernetes-dashboard namespace: kubernetes-dashboard spec: type: NodePort ports: - port: 443 targetPort: 8443 nodePort: 30000 selector: k8s-app: kubernetes-dashboard [root@master ~]# kubectl create -f recommended.yaml namespace/kubernetes-dashboard created serviceaccount/kubernetes-dashboard created service/kubernetes-dashboard created secret/kubernetes-dashboard-certs created secret/kubernetes-dashboard-csrf created secret/kubernetes-dashboard-key-holder created configmap/kubernetes-dashboard-settings created role.rbac.authorization.k8s.io/kubernetes-dashboard created clusterrole.rbac.authorization.k8s.io/kubernetes-dashboard created rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created clusterrolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created deployment.apps/kubernetes-dashboard created service/dashboard-metrics-scraper created deployment.apps/dashboard-metrics-scraper created
查看pod，service
[root@master k8s]# kubectl get node NAME STATUS ROLES AGE VERSION master Ready master 11m v1.18.0 [root@master k8s]# kubectl get service NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE kubernetes ClusterIP 10.10.0.1 <none> 443/TCP 11m [root@master k8s]# kubectl get svc -n kubernetes-dashboard NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE dashboard-metrics-scraper NodePort 10.10.197.176 <none> 8000:30572/TCP 51s kubernetes-dashboard ClusterIP 10.10.7.126 <none> 443/TCP 51s
通过页面访问，推荐使用firefox浏览器
一种使用配置文件，另一种使用token，此处使用token
使用token进行登录，执行下面命令获取token
kubectl create serviceaccount dashboard-admin -n kube-system kubectl create clusterrolebinding dashboard-admin --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-admin
#授权命名空间创建权限
kubectl create clusterrolebinding serviceaccounts-cluster-admin \ --clusterrole=cluster-admin \ --group=system:serviceaccounts
kubectl get secret -n kube-system #查看token
获取token通用代码 kubectl -n kube-system describe $(kubectl -n kube-system get secret -n kube-system -o name | grep namespace) | grep token
[root@master01 ~]# kubectl describe secrets -n kubernetes-dashboard kubernetes-dashboard-token-b5sd4 | grep token | awk 'NR==3{print $2}' eyJhbGciOiJSUzI1NiIsImtpZCI6IlE2RnRYZlJicGExR1pyckZ1ZmIybUxuTWdVdHN3ekxmeWxpR1VOWTZvNGcifQ.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.qWZ8I2buFE8o8_B7_byMt8GTWxBMFKnyuEtIOADR4LbbPL85k2Tsnb-RjpX9DCt6ZnvTnzH1bcDC8xQWuM-YForfMAXGN1sKv8DAgh75dTSSs1vppC4a9uDlHQNY2MrEqLNeM99SurF5w2lu5V7b9TLmtpk05GIedSKdGb1hbSRlI_m35AYLChu5lZayLNXJ9sum70SL20_IVe6UQPNS4XCa63g2NCe_kOAP-tfLKw1GmzBwtVTskHa2ImgVRT5GfyA-48DNkiXi51czDHNo1aNZUcdf7RLJ44kSsfommZIYX2J37LxQqFCIW8THBeIM7AQjjsAiTXYnYpWx4MKxBA
查看dashboard日志,大概就是一下样子，这个名字你要根据自己的名字改

此时再查看dashboard，即可看到有资源展示
至此为止已经安装完毕，node节点安装方法和上面基本一样，只是不用kb init,直接使用上面的命令即可
