安装kubernetes1.17.3多master节点的高可用集群

k8s1.18单master节点高可用集群安装-超详细中文官方文档

前言

这篇文章会带领大家去安装k8s1.18的多master节点高可用集群,上一篇介绍了单master节点高可用集群安装,大家如果上一篇已经测试通过,那么就开始这一篇的学习,去安装多master节点的高可用集群,如果你是初学小白,只要跟着做,也能保证100%完成安装,下面就正式开始我们的安装之旅吧,内容较多,万字长文,都是干货,可先关注,再慢慢学习~

为什么要安装多master节点的高可用集群?

在生产环境中,要想k8s集群稳定运行,那么我们就需要对k8s集群做高可用,大家可能都知道,k8s的master节点运行apiserver、scheduler、controller managr,etcd,codns等组件,apiserver负责资源请求,处理等操作,如果apiserver出问题,整个k8s集群就会处于不工作状态,为了防止这一现象的发生,就需要对master节点做高可用,也就是通过keepalive+lvs对多个master节点实现高可用和负载均衡,当一个master节点down掉,vip可以漂移到其他master节点,继续对外提供服务,保证k8s集群始终处于工作状态,具体实现请继续看下文~

心灵鸡汤

如果你觉得累,请看看下面这段话:我们想要去的地方,永远没有捷径,只有脚踏实地,一步一个脚印的才能走向诗和远方!

资料下载

1.下文需要的yaml文件所在的github地址:

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

大家可以把我的github仓库fork到你们自己的仓库里,这样就可以永久保存了,下面提供的yaml访问地址如果不能访问,那么就把这个github上的内容clone和下载到自己电脑,上面github地址是1.17.3,这个跟1.18是通用的,我没有单独列分支,大家可以直接拿来用。

下面实验用到yaml文件大家需要从上面的github上clone和下载到本地,然后把yaml文件传到k8s集群的master节点,如果直接复制粘贴格式可能会有问题。

2.下文里提到的初始化k8s集群需要的镜像获取方式:镜像在百度网盘,链接如下:

一、准备实验环境

1.准备四台centos7虚拟机,用来安装k8s集群,下面是四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,6G内存,两块60G硬盘
网络:桥接网络

 

master2(192.168.0.16)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

master3(192.168.0.26)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

 

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,4G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。

注:/etc/sysconfig/network-scripts/ifcfg-ens33文件里的配置说明:

NAME=ens33   

#网卡名字,跟DEVICE名字保持一致即可

DEVICE=ens33

#网卡设备名,大家ip addr可看到自己的这个网卡设备名,每个人的机器可能不一样,需要写自己的

BOOTPROTO=static  

#static表示静态ip地址

ONBOOT=yes   

#开机自启动网络,必须是yes

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

 1.2 在master2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

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

 1.3 在master3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=192.168.0.26
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

 1.4 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

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

执行如下清理缓存,生成新的yum源数据

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 ntp libaio-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 stop firewalld  && 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服务进程:

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192.168.0.16上:

hostnamectl set-hostname master2

 在192.168.0.26上:

hostnamectl set-hostname master3

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
192.168.0.16 master2
192.168.0.26 master3
192.168.0.56 node1

12.配置master1到node无密码登陆,配置master1到master2、master3无密码登陆

在master1上操作

ssh-keygen -t rsa

#一直回车就可以

ssh-copy-id -i .ssh/id_rsa.pub root@master2

#上面需要输入yes之后,输入密码,输入master2物理机密码即可

ssh-copy-id -i .ssh/id_rsa.pubroot@master3

#上面需要输入yes之后,输入密码,输入master3物理机密码即可

ssh-copy-id -i .ssh/id_rsa.pubroot@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 restart docker

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_rr ip_vs_wrr ip_vs_lblc ip_vs_lblcr ip_vs_dh ip_vs_sh ip_vs_fo ip_vs_nq ip_vs_sed ip_vs_ftp nf_conntrack"
for kernel_module in \${ipvs_modules}; do
 /sbin/modinfo -F filename \${kernel_module} > /dev/null 2>&1
 if [ $? -eq 0 ]; then
 /sbin/modprobe \${kernel_module}
 fi
done
EOF
chmod 755 /etc/sysconfig/modules/ipvs.modules && bash /etc/sysconfig/modules/ipvs.modules && lsmod | grep ip_vs

2.安装kubernetes1.18.2

2.1在master1、master2、master3和node1上安装kubeadm和kubelet

yum install kubeadm-1.18.2 kubelet-1.18.2 -y

systemctl enable kubelet

2.2上传镜像到master1、master2、master3和node1节点之后,按如下方法通过docker load -i手动解压镜像,镜像在百度网盘,文章最上面附有镜像所在的百度网盘地址,我是从官方下载的镜像,大家可以放心使用。

docker load -i   1-18-kube-apiserver.tar.gz

docker load -i   1-18-kube-scheduler.tar.gz

docker load -i   1-18-kube-controller-manager.tar.gz

docker load -i   1-18-pause.tar.gz

docker load -i   1-18-cordns.tar.gz

docker load -i   1-18-etcd.tar.gz

docker load -i   1-18-kube-proxy.tar.gz

说明:

pause版本是3.2,用到的镜像是k8s.gcr.io/pause:3.2

etcd版本是3.4.3,用到的镜像是k8s.gcr.io/etcd:3.4.3-0        

cordns版本是1.6.7,用到的镜像是k8s.gcr.io/coredns:1.6.7

 apiserver、scheduler、controller-manager、kube-proxy版本是1.18.2,用到的镜像分别是

k8s.gcr.io/kube-apiserver:v1.18.2

k8s.gcr.io/kube-controller-manager:v1.18.2

k8s.gcr.io/kube-scheduler:v1.18.2

k8s.gcr.io/kube-proxy:v1.18.2

为什么手动解压镜像?

1)因为很多同学的公司是内网环境,或者访问不了dockerhub镜像仓库,所以需要我们把镜像上传到各个机器手动解压,很多同学会问,如果机器很多,怎么办,难道还要把镜像拷贝到很多机器,这岂不是很费时间,的确,如果机器很多,我们只需要把这些镜像传到我们的内部私有镜像仓库即可,这样我们在kubeadm初始化kubernetes时可以通过"--image-repository=私有镜像仓库地址"的方式进行镜像拉取,这样不需要手动传到镜像到每个机器,后面会介绍;

2)镜像存到百度网盘可以永久使用,防止官方不在维护,我们无从下载镜像,所以有私有仓库的同学可以把这些镜像传到自己私有镜像仓库。

2.3 部署keepalive+lvs实现master节点高可用-对apiserver做高可用

(1)部署keepalived+lvs,在各master节点操作

yum install -y socat keepalived ipvsadm conntrack

重要知识点,必看,否则生产会遇到巨大的坑

keepalive需要配置BACKUP,而且是非抢占模式nopreempt,假设master1宕机,
启动之后vip不会自动漂移到master1,这样可以保证k8s集群始终处于正常状态,
因为假设master1启动,apiserver等组件不会立刻运行,如果vip漂移到master1,
那么整个集群就会挂掉,这就是为什么我们需要配置成非抢占模式了

启动顺序master1->master2->master3,在master1、master2、master3依次执行如下命令

systemctl enable keepalived  && systemctl start keepalived  && systemctl status keepalived

keepalived启动成功之后,在master1上通过ip addr可以看到vip已经绑定到ens33这个网卡上了

2.4 在master1节点初始化k8s集群,在master1上操作如下

如果按照我在2.2节手动上传镜像到各个节点那么用下面的yaml文件初始化,大家统一按照这种方法上传镜像到各个机器,手动解压,这样后面实验才会正常进行。

cat   kubeadm-config.yaml

apiVersion: kubeadm.k8s.io/v1beta2
kind: ClusterConfiguration
kubernetesVersion: v1.18.2
controlPlaneEndpoint: 192.168.0.199:6443
apiServer:
 certSANs:
 - 192.168.0.6
 - 192.168.0.16
 - 192.168.0.26
 - 192.168.0.56
 - 192.168.0.199
networking:
 podSubnet: 10.244.0.0/16
---
apiVersion: kubeproxy.config.k8s.io/v1alpha1
kind:  KubeProxyConfiguration
mode: ipvs

kubeadm init --config kubeadm-config.yaml

注:如果没有按照2.2节的方法上传镜像到各个节点,那么用下面的yaml文件,多了imageRepository: registry.aliyuncs.com/google_containers参数,表示走的是阿里云镜像,我们可以直接访问,这个方法更简单,但是在这里了解即可,先不使用这种方法,使用的话在后面手动加节点到k8s集群会有问题。

apiVersion: kubeadm.k8s.io/v1beta2
kind: ClusterConfiguration
kubernetesVersion: v1.18.2
controlPlaneEndpoint: 192.168.0.199:6443
imageRepository: registry.aliyuncs.com/google_containers
apiServer:
 certSANs:
 - 192.168.0.6
 - 192.168.0.16
 - 192.168.0.26
 - 192.168.0.56
 - 192.168.0.199
networking:
 podSubnet: 10.244.0.0/16
---
apiVersion: kubeproxy.config.k8s.io/v1alpha1
kind:  KubeProxyConfiguration
mode: ipvs

kubeadm init --config kubeadm-config.yaml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

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

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

You can now join any number of control-plane nodes by copying certificate authorities
and service account keys on each node and then running the following as root:

  kubeadm join 192.168.0.199:6443 --token 7dwluq.x6nypje7h55rnrhl \
    --discovery-token-ca-cert-hash sha256:fa75619ab0bb6273126350a9dbda9aa6c89828c2c4650299fe1647ab510a7e6c \
    --control-plane

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

kubeadm join 192.168.0.199:6443 --token 7dwluq.x6nypje7h55rnrhl \
    --discovery-token-ca-cert-hash sha256:fa75619ab0bb6273126350a9dbda9aa6c89828c2c4650299fe1647ab510a7e6c

 

注:kubeadm join ... 这条命令需要记住,我们把k8s的master2、master3,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

 

2.5 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   v1.18.2

 

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          3m16s
coredns-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   v1.18.2

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

 

2.6 把master1节点的证书拷贝到master2和master3上

(1)在master2和master3上创建证书存放目录

cd /root && mkdir -p /etc/kubernetes/pki/etcd &&mkdir -p ~/.kube/

(2)在master1节点把证书拷贝到master2和master3上,在master1上操作如下,下面的scp命令大家最好一行一行复制,这样不会出错:

scp /etc/kubernetes/pki/ca.crt master2:/etc/kubernetes/pki/ 

scp /etc/kubernetes/pki/ca.key master2:/etc/kubernetes/pki/ 

scp /etc/kubernetes/pki/sa.key master2:/etc/kubernetes/pki/

scp /etc/kubernetes/pki/sa.pub master2:/etc/kubernetes/pki/ 

scp /etc/kubernetes/pki/front-proxy-ca.crt master2:/etc/kubernetes/pki/ 

scp /etc/kubernetes/pki/front-proxy-ca.key master2:/etc/kubernetes/pki/ 

scp /etc/kubernetes/pki/etcd/ca.crt master2:/etc/kubernetes/pki/etcd/

scp /etc/kubernetes/pki/etcd/ca.key master2:/etc/kubernete/pki/etcd/

scp /etc/kubernetes/pki/ca.crt master3:/etc/kubernetes/pki/

scp /etc/kubernetes/pki/ca.key master3:/etc/kubernetes/pki/ 

scp /etc/kubernetes/pki/sa.key master3:/etc/kubernetes/pki/ 

scp /etc/kubernetes/pki/sa.pub master3:/etc/kubernetes/pki/ 

scp /etc/kubernetes/pki/front-proxy-ca.crt master3:/etc/kubernetes/pki/ 

scp /etc/kubernetes/pki/front-proxy-ca.key master3:/etc/kubernetes/pki/ 

scp /etc/kubernetes/pki/etcd/ca.crt master3:/etc/kubernetes/pki/etcd/

scp /etc/kubernetes/pki/etcd/ca.key master3:/etc/kubernetes/pki/etcd/

 证书拷贝之后在master2和master3上执行如下命令,大家复制自己的,这样就可以把master2和master3加入到集群

kubeadm join 192.168.0.199:6443 --token 7dwluq.x6nypje7h55rnrhl \
    --discovery-token-ca-cert-hash sha256:fa75619ab0bb6273126350a9dbda9aa6c89828c2c4650299fe1647ab510a7e6c   --control-plane

--control-plane:这个参数表示加入到k8s集群的是master节点

 

在master2和master3上操作:

   

    mkdir -p $HOME/.kube

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

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

kubectl get nodes 

显示如下:

NAME     STATUS   ROLES    AGE    VERSION
master1  Ready    master   39m    v1.18.2
master2  Ready    master   5m9s   v1.18.2
master3  Ready    master   2m33s  v1.18.2

 

2.7 把node1节点加入到k8s集群,在node1节点操作

kubeadm join 192.168.0.199:6443 --token 7dwluq.x6nypje7h55rnrhl \
    --discovery-token-ca-cert-hash sha256:fa75619ab0bb6273126350a9dbda9aa6c89828c2c4650299fe1647ab510a7e6c

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  v1.18.2
master2  Ready   master   3m36s  v1.18.2
master3  Ready   master   3m36s  v1.18.2
node1    Ready   <none>   3m36s  v1.18.2

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

2.9 安装traefik

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 or Province Name (full name)

stateOrProvinceName_value       = Beijing

localityName                    = Locality Name (eg, city)

localityName_value              = Haidian

organizationName                = Organization Name (eg, company)

organizationName_value          = Channelsoft

organizationalUnitName          = Organizational Unit 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 -days 3650 -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

3)查看traefik是否部署成功:

kubectl get pods -n kube-system

显示如下,说明部署成功

traefik-ingress-controller-csbp8   1/1     Running   0          5s
traefik-ingress-controller-hqkwf   1/1     Running   0          5s
traefik-ingress-controller-wtjqd   1/1     Running   0          5s


3.安装kubernetes-dashboard 2.0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

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 kube-system

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

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

点击sing in登陆,显示如下,这次就可以看到和操作任何名称空间的资源了

4.安装metrics监控相关的插件

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-master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上就可以正常使用了:

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

上面组件都安装之后,kubectl  get  pods  -n kube-system  -o wide,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
