1.环境规划
服务器为最小化部署
| 集群角色 | IP | 主机名 | 安装组件 |
|---|---|---|---|
| 控制节点 | 192.168.2.217 | master1 | apiserver、controller-manager、scheduler、kubelet、etcd、docker、kube-proxy、keepalived、nginx、calico |
| 工作节点1 | 192.168.2.219 | node1 | kubelet、docker、kube-proxy、calico、coredns |
| 工作节点2 | 192.168.2.239 | node2 | kubelet、docker、kube-proxy、calico、coredns |
k8s环境规划：
podSubnet（pod网段）10.244.0.0/16
serviceSubnet（service网段）: 10.96.0.0/12
kubeadm和二进制安装k8s适用场景分析
kubeadm是官方提供的开源工具，是一个开源项目，用于快速搭建kubernetes集群，目前是比较方便和推荐使用的。kubeadm init 以及 kubeadm join 这两个命令可以快速创建 kubernetes 集群。Kubeadm初始化k8s，所有的组件都是以pod形式运行的，具备故障自恢复能力。
kubeadm是工具，可以快速搭建集群，也就是相当于用程序脚本帮我们装好了集群，属于自动部署，简化部署操作，自动部署屏蔽了很多细节，使得对各个模块感知很少，如果对k8s架构组件理解不深的话，遇到问题比较难排查。
kubeadm适合需要经常部署k8s，或者对自动化要求比较高的场景下使用。
二进制：在官网下载相关组件的二进制包，如果手动安装，对kubernetes理解也会更全面。
Kubeadm和二进制都适合生产环境，在生产环境运行都很稳定，具体如何选择，可以根据实际项目进行评估。
2.初始化服务器
1）配置主机名
# 三个设备分别执行
[root@localhost ~]# hostnamectl set-hostname master1 && bash
[root@localhost ~]# hostnamectl set-hostname node1 && bash
[root@localhost ~]# hostnamectl set-hostname node2 && bash# && bash 当前会话立即生效
2）设置IP为静态IP
# 三个设备都需要修改-注意IP地址不要重复
[root@master1 ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens192
TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="static" # 由dhcp修改为static
IPADDR="192.168.2.217" # 设置IP地址
NETMASK="255.255.255.0" # 设置子网掩码
GATEWAY="192.168.2.1" # 设置网关：由ip route或netstat -rn等命令查询
DNS1="192.168.2.1" # 设置DNS
DNS2="8.8.8.8" # 设置DNS
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="ens32"
UUID="71ffc482-d255-4de0-a06c-0a5c036e8e96"
DEVICE="ens32"
ONBOOT="yes"
# node1(219)和node2(239)节点配置与上述配置除IP外，其余相同
# 重启网络
[root@master1 ~]# service network restart
3）关闭selinux
# 三个设备都需要修改
# 临时关闭
[root@master1 ~]# setenforce 0
# 永久关闭
[root@master1 ~]# vi /etc/selinux/config
# 将SELINUX设置为disabled
SELINUX=disabled
# 此参数修改完成后，需要重启服务器才能生效
# 检查修改状态
[root@master1 ~]# getenforce
显示为Disabled则说明修改成功
重启后检查结果如下（重启命令：reboot）
4）配置主机hosts文件
# 相互之间通过主机名互相访问，三个设备都需要修改
# 修改三台机器的/etc/hosts文件，增加如下三行
192.168.2.217 master1
192.168.2.219 node1
192.168.2.239 node2
# 修改后显示为
[root@master1 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.2.217 master1
192.168.2.219 node1
192.168.2.239 node2
5）配置三台主机之间免密登录
# 三台设备都生成证书，并将SSH信息复制到其他节点（可选）
[root@master1 ~]# ssh-keygen #一路回车，无需输入密码
[root@master1 ~]# ssh-copy-id master1 # 复制ssh信息到master1节点
[root@master1 ~]# ssh-copy-id node1 # 复制ssh信息到node1节点
[root@master1 ~]# ssh-copy-id node2 # 复制ssh信息到node2节点
6）关闭交换分区swap，提升性能
# 三台设备都运行
# 临时关闭
[root@master1 ~]# swapoff -a
# 永久关闭
[root@master1 ~]# vi /etc/fstab
# /dev/mapper/centos-swap swap swap defaults 0 0
# 关闭后需要重启服务器，否则在初始化k8s时候会报错
7）修改内核参数
# 三台设备都运行
# 加载模块
[root@master1~]# modprobe br_netfilter
# 修改内核参数（创建docker.conf文件并写入内核参数）
[root@master1 ~]# cat > /etc/sysctl.d/docker.conf <<EOF
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward = 1
EOF
# 使参数生效
[root@master1~]# sysctl -p /etc/sysctl.d/docker.conf
8）关闭firewalld防火墙
# 三台设备都运行
[root@master1~]# systemctl stop firewalld && systemctl disable firewalld
# 或 [root@master1 ~]# systemctl disable firewalld --now
9）配置阿里云repo源
# 三台设备都运行
# 默认yum源无法使用，需要更换成国内yum源，演示为阿里云yum源# 备份基础repo源
[root@master1 ~]# mkdir /root/repo.bak
[root@master1 ~]# cd /etc/yum.repos.d/
[root@master1 ~]# mv * /root/repo.bak/
# 把CentOS-Base.repo和epel.repo文件上传到各个主机的/etc/yum.repos.d/目录下（具体内容参考下述）# 修改后安装依赖进行测试
# 安装rzsz
[root@master1 ~]# yum install lrzsz -y
# 安装scp
[root@master1 ~]# yum install openssh-clients# 配置国内阿里云docker的repo源
[root@master1 ~]# yum install yum-utils -y
[root@master1 ~]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
CentOS-Base.repo文件内容
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

安装测试
操作完成后，目录下只存在3个repo
10）配置安装k8s组件需要的阿里云repo源
# 三台设备都运行
[root@master1 ~]# vi /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
11）配置时间同步
# 三台设备都运行
# 安装ntp服务
[root@docker ~]# yum -y install ntp ntpdate
# 同步时间（若存在本地时间服务器，可将cn.pool.ntp.org换成时间服务器IP）
[root@docker ~]# ntpdate cn.pool.ntp.org
# 编写计划任务
[root@docker ~]# crontab -e
输入：
* */1 * * * /usr/sbin/ntpdate cn.pool.ntp.org
# 可使用crontab -l命令查看
# 重启crond服务使配置生效
[root@docker ~]# systemctl restart crond
时间同步
制作定时任务及查看
12）安装基础软件包
# 三台设备都运行
[root@master1 ~]# yum install -y yum-utils device-mapper-persistent-data lvm2 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 telnet ipvsadm vim
3.安装docker服务
# 三台设备都运行
1）安装docker-ce指定版本
[root@docker ~]# yum install -y docker-ce-20.10.6 docker-ce-cli-20.10.6 containerd.io
# 启动docker服务并配置为自启动
[root@docker ~]# systemctl start docker && systemctl enable docker && systemctl status docker
# running 表示运行状态
2）配置docker镜像加速器和驱动
[root@master1 ~]# vim /etc/docker/daemon.json
{"registry-mirrors":["https://axcmsqgw.mirror.aliyuncs.com","https://registry.docker-cn.com","https://docker.mirrors.ustc.edu.cn","https://dockerhub.azk8s.cn","http://hub-mirror.c.163.com","http://qtid6917.mirror.aliyuncs.com", "https://rncxm540.mirror.aliyuncs.com"],"exec-opts": ["native.cgroupdriver=systemd"]
}
3）重新加载配置，且重启docker
[root@master1 ~]# systemctl daemon-reload && systemctl restart docker
4）安装初始化k8s需要的软件包
[root@master1 ~]# yum install -y kubelet-1.20.6 kubeadm-1.20.6 kubectl-1.20.6
# 配置开机自启动（先不用启动）
[root@master1 ~]# systemctl enable kubelet
注：每个软件包的作用
Kubeadm: kubeadm是一个工具，用来初始化k8s集群的
kubelet: 安装在集群所有节点上，用于启动Pod的
kubectl: 通过kubectl可以部署和管理应用，查看各种资源，创建、删除和更新各种组件
4.kubeadm初始化k8s
1）镜像下载并打包
# 需要的镜像为以下（建议master1节点拉取）
# 若全部节点拉起，则无需再将此镜像打包传输至工作节点
[root@master1 scripts]# docker pull registry.cn-hangzhou.aliyuncs.com/zhangxiaoye/app:calico_kube-controllers_v3.18.0
[root@master1 scripts]# docker pull registry.cn-hangzhou.aliyuncs.com/zhangxiaoye/app:calico_cni_v3.18.0

[root@master1 scripts]# docker pull registry.aliyuncs.com/google_containers/kube-apiserver:v1.20.6# 将下载的镜像打包到k8simages-1.20.6.tar.gz文件中，node节点就无需对镜像一个个进行下载
[root@master1 scripts]# docker save -o k8simages-1.20.6.tar.gz registry.cn-hangzhou.aliyuncs.com/zhangxiaoye/app:calico_kube-controllers_v3.18.0 registry.cn-hangzhou.aliyuncs.com/zhangxiaoye/app:calico_cni_v3.18.0 registry.cn-hangzhou.aliyuncs.com/zhangxiaoye/app:calico_node_v3.18.0 registry.cn-hangzhou.aliyuncs.com/zhangxiaoye/app:calico_pod2daemon-flexvol_v3.18.0 registry.aliyuncs.com/google_containers/coredns:1.7.0 registry.aliyuncs.com/google_containers/pause:3.2 registry.aliyuncs.com/google_containers/kube-controller-manager:v1.20.6 registry.aliyuncs.com/google_containers/kube-scheduler:v1.20.6 registry.aliyuncs.com/google_containers/etcd:3.4.13-0 registry.aliyuncs.com/google_containers/kube-proxy:v1.20.6 registry.aliyuncs.com/google_containers/kube-apiserver:v1.20.6
# 工作节点解压镜像
[root@node1 scripts]# docker load -i k8simages-1.20.6.tar.gz
[root@node2 scripts]# docker load -i k8simages-1.20.6.tar.gz
master1节点拉取镜像并打包传输至node节点
node节点解压镜像
2）kubeadm初始化master节点
# 仅master1节点执行即可
1.生成配置文件
[root@master1 ~]# kubeadm config print init-defaults > kubeadm.yaml2.修改配置文件
[root@master1 ~]# vim kubeadm.yaml
# advertiseAddress: 192.168.2.217 master节点IP
# name: master1 master节点主机名
# imageRepository: registry.cn-hangzhou.aliyuncs.com/google_containers 阿里云镜像仓库
# kubernetesVersion: v1.20.6 k8s版本
# serviceSubnet: 10.96.0.0/12 service网段
# podSubnet: 10.244.0.0/16 （新增）pod网段
# criSocket: /var/run/dockershim.sock 容器运行池
# 在scheduler: {}下一行，新增以下配置

kind: KubeProxyConfiguration
mode: ipvs
---
apiVersion: kubelet.config.k8s.io/v1beta1
kind: KubeletConfiguration
cgroupDriver: systemd
kubeadm.yaml文件内容如下：
[root@master1 ~]# cat kubeadm.yaml

3.基于kubeadm.yaml文件初始化k8s
[root@master1 scripts]# kubeadm init --config=kubeadm.yaml --ignore-preflight-errors=SystemVerification
# mster1安装完成后，需要执行以下命令
[root@master1 ~]# mkdir -p $HOME/.kube
[root@master1 ~]# sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
[root@master1 ~]# sudo chown $(id -u):$(id -g) $HOME/.kube/config# 配置文件查看
#直接查看
[root@master1 ~]# cat /root/.kube/config
# 使用kubectl查看
[root@master1 ~]# kubectl config view
注：
1.若第一次初始化失败，再次初始化的时候，提醒端口冲突，则重启kubeadm即可
或者检查swap分区是否关闭
[root@master1 scripts]# kubeadm reset
2.若k8s版本不对，需将原始版本卸载之后，再通过命令指定版本安装
[root@master1 ~]# yum remove -y kubelet kubeadm kubectl # 卸载
[root@master1 ~]# yum install -y kubelet-1.20.6 kubeadm-1.20.6 kubectl-1.20.6 # 安装
初始化完成成输出如下：
设置环境变量
3）查询k8s集群状态
[root@master1 scripts]# kubectl get nodes
# 其他节点查看集群状态，需要将master节点/root/.kube/目录下的config文件拷贝到对应服务器/root/.kube/目录下
[root@master1 ~]# kubectl get node
NAME STATUS ROLES AGE VERSION
master1 NotReady control-plane,master 59m v1.20.6
# 此时集群状态还是NotReady状态，因为没有安装网络插件# 查询kube-system命名空间下的所有pod

4）安装网络插件-Calico
# 仅master节点执行即可
下载地址：https://docs.projectcalico.org/manifests/calico.yaml
# 将calico.yaml上传至服务器，使用以下命令安装calico
[root@master1 ~]# kubectl apply -f calico.yaml
# 查看nodes状态，显示为ready即表示成功
[root@master1 ~]# kubectl get nodes

5）将工作节点添加进集群
在master1节点上执行命令，生成token
[root@master1 ~]# kubeadm token create --print-join-command
kubeadm join 192.168.2.217:6443 --token c1dy8g.nqobfc39ycv3uygo --discovery-token-ca-cert-hash sha256:fd0885ebdcc8dac61639f1e429cefa1cd7e5fcc4ab22dc3e7934247b1344af02
# 生成的token有效期为24小时
# 每次添加工作节点的时候，都需要执行该命令在工作节点上，执行生成的命令并添加参数（生成两个，在两个工作节点上分别执行）
# --ignore-preflight-errors=SystemVerification
[root@node1 ~]# kubeadm join 192.168.2.217:6443 --token c1dy8g.nqobfc39ycv3uygo --discovery-token-ca-cert-hash sha256:fd0885ebdcc8dac61639f1e429cefa1cd7e5fcc4ab22dc3e7934247b1344af02 --ignore-preflight-errors=SystemVerification[root@node2 ~]# kubeadm join 192.168.2.217:6443 --token alhlos.h5x5d9y2ddix4dtw --discovery-token-ca-cert-hash sha256:fd0885ebdcc8dac61639f1e429cefa1cd7e5fcc4ab22dc3e7934247b1344af02 --ignore-preflight-errors=SystemVerification
# 注意：
# 若已经执行过kubeadm join 172.16.32.128:6443 --token xxx命令，再次执行的时候，将无法添加，需要通过命令kubeadm reset重置k8s将工作节点添加进集群后，查询k8s集群状态
[root@master1 ~]# kubectl get nodes
NAME STATUS ROLES AGE VERSION
master1 Ready control-plane,master 77m v1.20.6
node1 Ready <none> 66s v1.20.6
node2 Ready <none> 61s v1.20.6
# 工作节点的ROLES默认显示为none，若想显示为其他，可以通过在master节点指定命令，对工作节点生成标签
# 打标签
[root@master1 ~]# kubectl label node node1 node-role.kubernetes.io/node1=node1
# 删除标签
[root@master1 ~]# kubectl label node node1 node-role.kubernetes.io/node1-
将node节点加入集群
集群状态查看
更换标签后查看
至此，k8s 1.20.6版本单master多node集群已经搭建完毕。
5. 测试
1）测试k8s创建pod是否可以正常访问网络
# 将busybox-1-28.tar.gz上传至三台服务器
解压busybox-1-28.tar.gz，使每个节点上都有busybox:1.28镜像
[root@master1 ~]# docker load -i busybox-1-28.tar.gz
# master1节点上调用镜像运行pod
[root@master1 ~]# kubectl run busybox --image busybox:1.28 --image-pull-policy=IfNotPresent --restart=Never --rm -it busybox -- sh# 新开一个窗口，查询pod运行在哪个node节点上
[root@master1 ~]# kubectl get pods -o wide
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
busybox 1/1 Running 0 3m43s 10.244.104.5 node2 <none> <none># 切换进busybox的pod中

# 能够正常解析，说明calico插件安装正常
测试网络
2）测试coredns解析是否正常
# 切换进busybox的pod中
[root@master1 ~]# kubectl run busybox --image busybox:1.28 --image-pull-policy=IfNotPresent --restart=Never --rm -it busybox -- sh
# 测试coredns解析是否正常
/ # nslookup kubernetes.default.svc.cluster.local
