装置之前的筹备：

装置docker

应用国内 daocloud 一键装置命令：

curl -sSL https://get.daocloud.io/docker | sh

间接从dockerhub下载镜像太慢, 须要配置国内镜像源, 批改daemon.json文件
增加镜像源, luffy应用的是中科大的镜像源

cat <<EOF >/etc/docker/daemon.json{  "registry-mirrors": ["https://docker.mirrors.ustc.edu.cn/"]}  EOF

启动docker

sudo systemctl daemon-reloadsudo systemctl restart docker

装置kubelet,kubectl,kubeadm：

关上apt源文件：

vim /etc/apt/sources.list

增加如下：

deb https://mirrors.aliyun.com/kubernetes/apt kubernetes-xenial main

而后更新apt源：

apt-get update
ps:如果呈现上面谬误
W: GPG error: https://mirrors.aliyun.com/ku... kubernetes-xenial InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY FEEA9169307EA071 NO_PUBKEY 8B57C5C2836F4BEB

执行装置GPG秘钥：

curl https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg |sudo apt-key add -

在进行

apt-get update

装置kube：

apt-get install -y kubelet=1.18.0-00 kubeadm=1.18.0-00 kubectl=1.18.0-00

启动master节点

查看镜像列表

kubeadm config images list --kubernetes-version v1.18.0

拉取镜像：

docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/kube-apiserver:v1.18.0docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/kube-controller-manager:v1.18.0docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/kube-scheduler:v1.18.0docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/kube-proxy:v1.18.0docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.2docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/etcd:3.4.3-0docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/coredns:1.6.7

给镜像改名：

docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/kube-apiserver:v1.18.0 k8s.gcr.io/kube-apiserver:v1.18.0docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/kube-controller-manager:v1.18.0 k8s.gcr.io/kube-controller-manager:v1.18.0docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/kube-scheduler:v1.18.0 k8s.gcr.io/kube-scheduler:v1.18.0docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/kube-proxy:v1.18.0 k8s.gcr.io/kube-proxy:v1.18.0docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.2 k8s.gcr.io/pause:3.2docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/etcd:3.4.3-0 k8s.gcr.io/etcd:3.4.3-0docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/coredns:1.6.7 k8s.gcr.io/coredns:1.6.7

留神：以上三步对于镜像的操作也能够间接写到一个脚本里，for循环来执行，详情能够查问脚本操作。

vim k8s-pull.sh

增加内容：

#将对应的包, 从国内镜像上拉下来for  i  in  `kubeadm config images list --kubernetes-version v1.18.0`;  do    imageName=${i#k8s.gcr.io/}    docker pull registry.aliyuncs.com/google_containers/$imageName    docker tag registry.aliyuncs.com/google_containers/$imageName k8s.gcr.io/$imageName    docker rmi registry.aliyuncs.com/google_containers/$imageNamedone;

执行脚本

sh k8s-pull.sh

镜像下载实现，能够启动master节点了：

kubeadm init --kubernetes-version=v1.18.0 --pod-network-cidr=10.10.0.0/16 --apiserver-advertise-address=172.18.10.172 --ignore-preflight-errors=NumCPU
留神172.18.10.172是我的服务器内网地址，留神替换，--ignore-preflight-errors=NumCPU 是因为我的服务器是买的低配单核，加上就疏忽启动是的cpu外围数报错，多核 的不必加这个

设置配置文件如下：

mkdir -p /root/.kubecp -i /etc/kubernetes/admin.conf /root/.kube/configchown root:root /root/.kube/config

设置网络插件

export KUBECONFIG=/etc/kubernetes/admin.confkubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
mkdir -p /etc/cni/net.d

编辑网络通道配置列表（没有会默认创立）

vi 10-flannel.conflist
{    undefined"name": "cbr0",    "plugins": [        {            undefined"type": "flannel",            "delegate": {                undefined"hairpinMode": true,                "isDefaultGateway": true            }        },        {            undefined"type": "portmap",            "capabilities": {                undefined"portMappings": true            }        }    ]}

屡次刷新查看是否relay

kubectl get nodes

显示Ready示意执行胜利

NAME                      STATUS   ROLES    AGE   VERSIONizwz91w9jegcgf28ttbe2yz   Ready    master   46h   v1.18.0

重启kubelet

systemctl daemon-reloadsystemctl restart kubelet

装置 kubernetes-dashboard

下载包

wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0/aio/deploy/recommended.yaml

能够批改下名字kubernetes-dashboard，编辑配置文件

vim kubernetes-dashboard.yaml

上面我这个曾经批改好了没有坑，留神下端口就行

更新dashboard配置

kubectl apply -f kubernetes-dashboard.yaml

查看dashboard端口

kubectl get pod,deploy,svc --all-namespaces

返回上面数据都显示running：示意胜利
在这里插入图片形容

登录dashboard

此时通过 https://服务器外网ip:30443
能够拜访dashboard页面

生成登陆须要的token：

1：建设service account

kubectl create sa dashboard-admin -n kube-system

2：建设角色绑定关系

kubectl create clusterrolebinding dashboard-admin --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-admin

3：查看dashboard-admin的secret名字

ADMIN_SECRET=$(kubectl get secrets -n kube-system | grep dashboard-admin | awk '{print $1}')echo ADMIN_SECRET

4：打印secret的token

kubectl describe secret -n kube-system ${ADMIN_SECRET} | grep -E '^token' | awk '{print $2}'

备注：有什么问题能够查看日志，排查

journalctl -xeu kubelet
