**一、准备实验环境**

1.准备两台centos7虚拟机，用来安装k8s集群，下面是两台虚拟机的配置情况

**master1****（192.168.0.6）配置：**

操作系统：centos7.6以及更高版本都可以配置：4核cpu，8G内存，两块60G硬盘

网络：桥接网络

**node1****（192.168.0.56）配置：**

操作系统：centos7.6以及更高版本都可以配置：4核cpu，6G内存，两块60G硬盘

网络：桥接网络

**二、初始化实验环境**

**1.****配置静态ip**

把虚拟机或者物理机配置成静态ip地址，这样机器重新启动后ip地址也不会发生改变。

**1.1** **在master1节点配置网络**

**修改/etc/sysconfig/network-scripts/ifcfg-ens33文件，变成如下：**

TYPE=Ethernet

PROXY\_METHOD=none

BROWSER\_ONLY=no

BOOTPROTO=static

IPADDR=192.168.0.6

NETMASK=255.255.255.0

GATEWAY=192.168.0.1

DNS1=192.168.0.1

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

DEVICE=ens33

ONBOOT=yes

**修改配置文件之后需要重启网络服务才能使配置生效，重启网络服务命令如下：**

service network restart

**注：**ifcfg-ens33文件配置解释：

IPADDR=192.168.0.6

\#ip地址，需要跟自己电脑所在网段一致

NETMASK=255.255.255.0

\#子网掩码，需要跟自己电脑所在网段一致

GATEWAY=192.168.0.1

\#网关，在自己电脑打开cmd，输入ipconfig /all可看到

DNS1=192.168.0.1

\#DNS，在自己电脑打开cmd，输入ipconfig /all可看到

** **

**1.2** **在node1节点配置网络**

**修改/etc/sysconfig/network-scripts/ifcfg-ens33文件，变成如下：**

TYPE=Ethernet

PROXY\_METHOD=none

BROWSER\_ONLY=no

BOOTPROTO=static

IPADDR=192.168.0.56

NETMASK=255.255.255.0

GATEWAY=192.168.0.1

DNS1=192.168.0.1

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

DEVICE=ens33

ONBOOT=yes

**修改配置文件之后需要重启网络服务才能使配置生效，重启网络服务命令如下：**

service network restart

**2.****修改yum源，各个节点操作**

（1）备份原来的yum源

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

（2）下载阿里的yum源

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

（3）生成新的yum缓存

yum makecache fast

（4）配置安装k8s需要的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=0

EOF

（5）清理yum缓存

yum clean all

（6）生成新的yum缓存

yum makecache fast

（7）更新yum源

yum -y update

（8）安装软件包

yum -y install yum-utils device-mapper-persistent-data  lvm2

（9）添加新的软件源

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

yum clean all

yum makecache fast

**3.****安装基础软件包，各个节点操作**

yum -y install wget net-tools nfs-utils lrzsz gcc gcc-c++ make cmake libxml2-devel openssl-devel curl curl-devel unzip sudo ntplibaio-devel wget vim ncurses-devel autoconf automake zlib-devel  python-devel epel-release openssh-server socat  ipvsadm conntrack ntpdate

**4.****关闭firewalld防火墙，各个节点操作，centos7系统默认使用的是firewalld防火墙，停止firewalld防火墙，并禁用这个服务**

systemctl stopfirewalld  && systemctl  disable firewalld

**5.****安装iptables，各个节点操作，如果你用firewalld不是很习惯，可以安装iptables，这个步骤可以不做，根据大家实际需求**

5.1 安装iptables

yum install iptables-services -y

5.2 禁用iptables

service iptables stop  && systemctl disable iptables

**6.****时间同步，各个节点操作**

6.1 时间同步

ntpdate cn.pool.ntp.org

6.2 编辑计划任务，每小时做一次同步

1）crontab -e

\* \*/1 \* \* \* /usr/sbin/ntpdate   cn.pool.ntp.org

2）重启crond服务：

service crond restart

**7.** **关闭selinux，各个节点操作**

关闭selinux，设置永久关闭，这样重启机器selinux也处于关闭状态

修改/etc/sysconfig/selinux和/etc/selinux/config文件，把

SELINUX=enforcing变成SELINUX=disabled，也可用下面方式修改：

sed -i  's/SELINUX=enforcing/SELINUX=disabled/' /etc/sysconfig/selinux

sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

**上面文件修改之后，需要重启虚拟机，可以强制重启：**

reboot -f

**8.****关闭交换分区，各个节点操作**

swapoff  -a

\#永久禁用，打开/etc/fstab注释掉swap那一行。

sed -i 's/.\*swap.\*/\#&/' /etc/fstab

**9.****修改内核参数，各个节点操作**

cat <<EOF > /etc/sysctl.d/k8s.conf

net.bridge.bridge-nf-call-ip6tables = 1

net.bridge.bridge-nf-call-iptables = 1

EOF

sysctl --system

**10.****修改主机名**

在192.168.0.6上：

hostnamectl set-hostname master1

在192.168.0.56上：

hostnamectl set-hostname node1

**11.****配置hosts文件，各个节点操作**

在/etc/hosts文件增加如下几行：

192.168.0.6 master1

192.168.0.56 node1

**12.****配置master1到node1无密码登陆，配置master1到node1无密码登陆**

在master1上操作

ssh-keygen -t rsa

\#一直回车就可以

cd /root && ssh-copy-id -i .ssh/id\_rsa.pub root@node1

\#上面需要输入yes之后，输入密码，输入node1物理机密码即可

**三、安装kubernetes1.18.2单master节点的高可用集群**

**1.****安装docker19.03，各个节点操作**

**1.1** **查看支持的docker版本**

yum list docker-ce --showduplicates |sort -r

**1.2** **安装19.03.7版本**

yum install -y docker-ce-19.03.7-3.el7

systemctl enable docker && systemctl start docker

\#查看docker状态，如果状态是active（running），说明docker是正常运行状态

systemctl status docker

**1.3** **修改docker配置文件**

cat > /etc/docker/daemon.json <<EOF

"exec-opts":\["native.cgroupdriver=systemd"\],

"log-driver":"json-file",

"log-opts": \{

"max-size": "100m"

\},

"storage-driver":"overlay2",

"storage-opts": \[

"overlay2.override\_kernel\_check=true"

EOF

**1.4** **重启docker使配置生效**

systemctl daemon-reload && systemctl restartdocker

**1.5** **设置网桥包经IPTables，core文件生成路径，配置永久生效**

echo 1 > /proc/sys/net/bridge/bridge-nf-call-iptables

echo 1 >/proc/sys/net/bridge/bridge-nf-call-ip6tables

echo """

vm.swappiness = 0

net.bridge.bridge-nf-call-iptables = 1

net.ipv4.ip\_forward = 1

net.bridge.bridge-nf-call-ip6tables = 1

""" > /etc/sysctl.conf

sysctl -p

**1.6** **开启ipvs，不开启ipvs将会使用iptables，但是效率低，所以官网推荐需要开通ipvs内核**

cat > /etc/sysconfig/modules/ipvs.modules <<EOF

\#!/bin/bash

ipvs\_modules="ip\_vs ip\_vs\_lc ip\_vs\_wlc ip\_vs\_rrip\_vs\_wrr ip\_vs\_lblc ip\_vs\_lblcr ip\_vs\_dh ip\_vs\_sh ip\_vs\_fo ip\_vs\_nq ip\_vs\_sedip\_vs\_ftp nf\_conntrack"

for kernel\_module in \\$\{ipvs\_modules\}; do

/sbin/modinfo -Ffilename \\$\{kernel\_module\} > /dev/null 2>&1

if \[ $? -eq 0 \];then

/sbin/modprobe\\$\{kernel\_module\}

done

EOF

modprobe ip\_vs

chmod 755 /etc/sysconfig/modules/ipvs.modules &&bash /etc/sysconfig/modules/ipvs.modules && lsmod | grep ip\_vs

**2.****安装kubernetes1.18.6**

**2.1****在master1和node1上安装kubeadm和kubelet**

yum install kubeadm-1.18.6 kubelet-1.18.6 -y

systemctl enable kubelet

**初始化k8s集群**

kubeadm init  --kubernetes-version=v1.18.6  --pod-network-cidr=10.244.0.0/16 --apiserver-advertise-address=192.168.0.6 --image-repository registry.aliyuncs.com/google\_containers

注：

--image-repository registry.aliyuncs.com/google_containers是指定阿里云的镜像源，基于这个我们可以安装任何版本的k8s； 
    --kubernetes-version=v1.18.6是指定k8s版本

**初始化命令执行成功之后显示如下内容，说明初始化成功了**

Your Kubernetes control-plane has initialized successfully!

To start using your cluster, you need to run the following as a regularuser:

mkdir -p $HOME/.kube

sudo cp -i/etc/kubernetes/admin.conf $HOME/.kube/config

sudo chown $(id -u):$(id -g)$HOME/.kube/config

You should now deploy a pod network to the cluster.

Run "kubectl apply -f \[podnetwork\].yaml" with one of the optionslisted at:

https://kubernetes.io/docs/concepts/cluster-administration/addons/

Then you can join any number of worker nodes by running the following oneach as root:

kubeadm join 192.168.0.6:6443 --token si1c9n.3c5os94xcuzq6wl3 \\

\--discovery-token-ca-cert-hashsha256:9d3a35eab0f6badba61ebb833d420902e4f9e0168ee1c1374121668ab382a596

**注：**kubeadm join ... 这条命令需要记住，我们把k8s的node1节点加入到集群需要在这些节点节点输入这条命令，每次执行这个结果都是不一样的，大家记住自己执行的结果，在下面会用到

**2.2** **在master1节点执行如下，这样才能有权限操作k8s资源**

mkdir -p $HOME/.kube

sudo cp -i  /etc/kubernetes/admin.conf $HOME/.kube/config

sudo chown $(id -u):$(id -g)  $HOME/.kube/config

在master1节点执行

kubectl get nodes

显示如下，master1节点是NotReady

NAME     STATUS     ROLES    AGE    VERSION master1   NotReady   master   8m11s   v1.18.6

kubectl get pods -n kube-system

显示如下，可看到cordns也是处于pending状态

coredns-7ff77c879f-j48h6              0/1    Pending  0          3m16scoredns-7ff77c879f-lrb77         0/1    Pending  0          3m16s

上面可以看到STATUS状态是NotReady，cordns是pending，是因为没有安装网络插件，需要安装calico或者flannel，接下来我们安装calico，在master1节点安装calico网络插件：

安装calico需要的镜像是quay.io/calico/cni:v3.5.3和quay.io/calico/node:v3.5.3，镜像在文章开头处的百度网盘地址

手动上传上面两个镜像的压缩包到各个节点，通过docker load -i解压

docker load -i   cni.tar.gz  
docker load -i   calico-node.tar.gz

**在master1节点执行如下**

kubectl apply -f calico.yaml

calico.yaml文件内容在如下提供的地址，打开下面链接可复制内容：

https://raw.githubusercontent.com/luckylucky421/kubernetes1.17.3/master/calico.yaml

如果打不开上面的链接,可以访问下面的github地址，把下面的目录clone和下载下来，解压之后，在把文件传到master1节点即可

https://github.com/luckylucky421/kubernetes1.17.3/tree/master

**在master1节点执行**

kubectl get nodes

显示如下，看到STATUS是Ready

NAME    STATUS   ROLES    AGE  VERSION

master1  Ready    master   98m  v1.18.6

kubectl get pods -n kube-system

看到cordns也是running状态，说明master1节点的calico安装完成

NAME                           READY   STATUS   RESTARTS   AGE
    calico-node-6rvqm               1/1     Running  0          17m
    coredns-7ff77c879f-j48h6        1/1    Running   0          97m
    coredns-7ff77c879f-lrb77        1/1    Running   0          97m
    etcd-master1                    1/1     Running  0          97m
    kube-apiserver-master1          1/1     Running  0          97m
    kube-controller-manager-master1 1/1     Running  0          97m
    kube-proxy-njft6                1/1     Running  0          97m
    kube-scheduler-master1          1/1     Running  0          97m

**2.3** **把node1节点加入到k8s集群，在node1节点操作**

kubeadm join 192.168.0.6:6443 --token si1c9n.3c5os94xcuzq6wl3 \\

\--discovery-token-ca-cert-hashsha256:9d3a35eab0f6badba61ebb833d420902e4f9e0168ee1c1374121668ab382a596

**注：**上面的这个加入到k8s节点的一串命令kubeadm join就是在2.4初始化的时候生成的

**2.8** **在master1节点查看集群节点状态**

kubectl get nodes

显示如下：

NAME       STATUS     ROLES    AGE   VERSION

master1    Ready   master   3m36s v1.18.6

node1      Ready   <none>   3m36s v1.18.6

说明node1节点也加入到k8s集群了，通过以上就完成了k8s单master高可用集群的搭建

**2.4** **安装traefik**

**官网：https://docs.traefik.io/**

把traefik镜像上传到各个节点，按照如下方法通过docker load -i解压，镜像地址在文章开头处的百度网盘里，可自行下载

docker load -i  traefik\_1\_7\_9.tar.gz

traefik用到的镜像是k8s.gcr.io/traefik:1.7.9

1）生成traefik证书，在master1上操作

mkdir  ~/ikube/tls/ -p

echo """

\[req\]

distinguished\_name = req\_distinguished\_name

prompt = yes

\[ req\_distinguished\_name \]

countryName                    = Country Name (2 letter code)

countryName\_value               = CN

stateOrProvinceName             = State orProvince Name (full name)

stateOrProvinceName\_value       = Beijing

localityName                   = Locality Name (eg, city)

localityName\_value              =Haidian

organizationName                =Organization Name (eg, company)

organizationName\_value          = Channelsoft

organizationalUnitName          = OrganizationalUnit Name (eg, p)

organizationalUnitName\_value    = R & D Department

commonName                     = Common Name (eg, your name or your server\\'s hostname)

commonName\_value                =\*.multi.io

emailAddress                   = Email Address

emailAddress\_value              =lentil1016@gmail.com

""" > ~/ikube/tls/openssl.cnf

openssl req -newkey rsa:4096 -nodes -config ~/ikube/tls/openssl.cnf -days3650 -x509 -out ~/ikube/tls/tls.crt -keyout ~/ikube/tls/tls.key

kubectl create -n kube-system secret tls ssl --cert ~/ikube/tls/tls.crt--key ~/ikube/tls/tls.key

2）执行yaml文件，创建traefik

kubectl apply -f traefik.yaml

traefik.yaml文件内容在如下链接地址处复制：

https://raw.githubusercontent.com/luckylucky421/kubernetes1.17.3/master/traefik.yaml

上面如果访问不了，可以访问下面的链接，然后把下面的分支克隆和下载，手动把yaml文件传到master1上即可：

https://github.com/luckylucky421/kubernetes1.17.3

3）查看traefik是否部署成功：

kubectl get pods -n kube-system
    traefik-ingress-controller-csbp8  1/1     Running   0         5s
    traefik-ingress-controller-hqkwf  1/1     Running   0         5s

**3.****安装kubernetes-dashboard-2版本（kubernetes的web ui界面）**

把kubernetes-dashboard镜像上传到各个节点，按照如下方法通过docker load -i解压，镜像地址在文章开头处的百度网盘里，可自行下载

docker load -i dashboard\_2\_0\_0.tar.gz

docker load -i metrics-scrapter-1-0-1.tar.gz

解压出来的镜像是kubernetesui/dashboard:v2.0.0-beta8和kubernetesui/metrics-scraper:v1.0.1

**在master1节点操作**

kubectl apply -f kubernetes-dashboard.yaml

kubernetes-dashboard.yaml文件内容在如下链接地址处复制https://raw.githubusercontent.com/luckylucky421/kubernetes1.17.3/master/kubernetes-dashboard.yaml

上面如果访问不了，可以访问下面的链接，然后把下面的分支克隆和下载，手动把yaml文件传到master1上即可：

https://github.com/luckylucky421/kubernetes1.17.3

查看dashboard是否安装成功：

kubectl get pods -n kubernetes-dashboard

显示如下，说明dashboard安装成功了

NAME                                        READY   STATUS    RESTARTS  AGE 
    dashboard-metrics-scraper-694557449d-8xmtf   1/1    Running   0          60s  
    kubernetes-dashboard-5f98bdb684-ph9wg        1/1    Running   2          60s

查看dashboard前端的service

kubectl get svc -n kubernetes-dashboard

显示如下：

NAME                       TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)   AGE  
    dashboard-metrics-scraper ClusterIP  10.100.23.9       <none>        8000/TCP   50s  
    kubernetes-dashboard       ClusterIP   10.105.253.155   <none>        443/TCP    50s

修改service type类型变成NodePort：

kubectl edit svc kubernetes-dashboard -n kubernetes-dashboard

把type: ClusterIP变成 type: NodePort，保存退出即可。

kubectl get svc -n kubernetes-dashboard

显示如下：

NAME                       TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)         AGE
    dashboard-metrics-scraper  ClusterIP   10.100.23.9      <none>        8000/TCP        3m59s
    kubernetes-dashboard       NodePort    10.105.253.155   <none>        443:31175/TCP   4m

上面可看到service类型是NodePort，访问master1节点ip:31175端口即可访问kubernetes dashboard，我的环境需要输入如下地址

https://192.168.0.6:31775/

可看到出现了dashboard界面

![format_png][]

**3.1****通过yaml文件里指定的默认的token登陆dashboard**

**1****）查看kubernetes-dashboard名称空间下的secret**

kubectl get secret -n kubernetes-dashboard

**显示如下：**

NAME                              TYPE                                 DATA   AGE

**3.2** **创建管理员token，可查看任何空间权限**

kubectl create clusterrolebinding dashboard-cluster-admin--clusterrole=cluster-admin --serviceaccount=kubernetes-dashboard:kubernetes-dashboard

**1****）查看kubernetes-dashboard名称空间下的secret**

kubectl get secret -n kubernetes-dashboard

**显示如下：**

NAME                              TYPE                                 DATA   AGE

**4.****安装metrics组件**

把metrics-server-amd64\_0\_3\_1.tar.gz和addon.tar.gz镜像上传到各个节点，按照如下方法通过docker load -i解压，镜像地址在文章开头处的百度网盘里，可自行下载

docker load -i metrics-server-amd64\_0\_3\_1.tar.gz

docker load -i addon.tar.gz

metrics-server版本0.3.1，用到的镜像是k8s.gcr.io/metrics-server-amd64:v0.3.1

addon-resizer版本是1.8.4，用到的镜像是k8s.gcr.io/addon-resizer:1.8.4

**在k8s的master1节点操作**

kubectl apply -f metrics.yaml

metrics.yaml文件内容在如下链接地址处复制

https://raw.githubusercontent.com/luckylucky421/kubernetes1.17.3/master/metrics.yaml

上面如果访问不了，可以访问下面的链接，然后把下面的分支克隆和下载，手动把yaml文件传到master1上即可：

https://github.com/luckylucky421/kubernetes1.17.3

上面组件都安装之后，查看组件安装是否正常，STATUS状态是Running，说明组件正常，如下所示：

**kubectl  get  pods  -n kube-system  -o wide**

上面如果看到metrics-server-8459f8db8c-gqsks是running状态，说明metrics-server组件部署成功了，接下来就可以在master1节点上使用kubectl top pods -n kube-system或者kubectl top nodes命令
