---

一、环境准备

• 一台兼容的 Linux 主机。Kubernetes 项目为基于 Debian 和 Red Hat 的 Linux 发行版以及一些不提供包管理器的发行版提供通用的指令。
• 每台机器 2 GB 或更多的 RAM （如果少于这个数字将会影响你应用的运行内存)。
• 2 CPU 核或更多。
• 集群中的所有机器的网络彼此均能相互连接(公网和内网都可以)。
• 节点之中不可以有重复的主机名、MAC 地址或 product_uuid。
• 开启机器上的某些端口。
• 禁用交换分区。为了保证 kubelet 正常工作，你 必须 禁用交换分区。

本文安装k8s集群在Linux7.9下安装

ip地址	名称	操作系统	服务配置
192.168.139.173	master	CentOS Linux release 7.9.2009	2核CPU 2G内存 20G硬盘
192.168.139.177	node1	CentOS Linux release 7.9.2009	2核CPU 2G内存 20G硬盘
192.168.139.177	node2	CentOS Linux release 7.9.2009	2核CPU 2G内存 20G硬盘

1、查看linux系统版本（每个节点上都要执行）

cat /etc/redhat-release 

 2、查看mac地址（每个节点上都要执行）

ifconfig -a

报找不到指令安装指令

sudo yum install net-tools

 3、配置每个节点的网络，然后能互相ping通（每个节点上都要执行）

vi /etc/hosts

 添加如下内容，实际情况请填写自己的ip

192.168.139.180  master
192.168.139.179  node1
192.168.139.181  node2

 各个节点是否可以ping通

• ping master 
• ping node1
• ping node2

4、安装时间插件，保证每个节点时间一致（每个节点上都要执行）

yum install -y chrony
systemctl start chronyd
systemctl enable chronyd

 5、开启端口，这里为了省事直接关闭防火墙（每个节点上都要执行）

 

 如果不想关闭防火墙，以上的端口是必须要开启的

systemctl stop firewalld && systemctl disable firewalld

6、禁用SELINUX（每个节点上都要执行）

sed -i 's/^SELINUX=.*/SELINUX=disabled/' /etc/selinux/config  && setenforce 0

 或者手动修改SELINUX=disabled

vi /etc/selinux/config 

7、禁用swap分区（每个节点上都要执行）

# 临时
swapoff -a
#永久
sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab

 或者执行以下命令注释掉/dev/mapper/centos-swap swap  行。

vi /etc/fstab

8、 允许 iptables 检查桥接流量和地址转发（每个节点上都要执行）

cat <<EOF | sudo tee /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward = 1
EOF

#重新加载
sudo sysctl --system
#加载br_netfilter模块
modprobe br_netfilter
#查看网桥过滤模块是否加载成功
lsmod  | grep br_netfilter

 如下则配置成功

 9、配置ipvs功能（每个节点上都要执行）

#安装
yum install ipset ipvsadm -y
#配置
cat <<EOF > /etc/sysconfig/modules/ipvs.modules
#!/bin/bash
modprobe -- ip_vs
modprobe -- ip_vs_rr
modprobe -- ip_vs_wrr
modprobe -- ip_vs_sh
modprobe -- nf_conntrack_ipv4
EOF
#授权
chmod +x /etc/sysconfig/modules/ipvs.modules
#执行
sh +x /etc/sysconfig/modules/ipvs.modules
#查看
lsmod | grep -e ip_vs -e nf_conntrack_ipv4

 10、重启服务器让SELINUX生效

reboot -h now

二、docker安装

1、docker安装（每个节点上都要执行）

#更新yum源
yum -y update

#安装软件包
yum install -y yum-utils device-mapper-persistent-data lvm2

#设置镜像仓库
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

#查看版本列表
yum list docker-ce-cli --showduplicates|sort -r

#指定安装版本
yum install --setopt=obsoletes=0 docker-ce-20.10.9-3.el7 -y 

#启动docker
systemctl start docker

#设置开机启动
systemctl enable docker

#检测安装是否成功
docker version

 2、配置加速镜像（每个节点上都要执行）

#创建文件
sudo mkdir -p /etc/docker
#配置
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "exec-opts": ["native.cgroupdriver=systemd"],
  "registry-mirrors": ["https://3kcpregv.mirror.aliyuncs.com"]
}
EOF
#重启docker
 systemctl restart docker

三、Kubernetes集群安装

1、配置阿里云yum源（每个节点上都要执行）

cat > /etc/yum.repos.d/kubernetes.repo << EOF
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg         
       https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF

2、安装kubeadm、kubelet和kubectl（每个节点上都要执行）

yum install --setopt=obsoletes=0 kubelet-1.23.6 kubeadm-1.23.6 kubectl-1.23.6 -y

3、 修改kubelet驱动和docker驱动一样（每个节点上都要执行）

#编辑文件
vi /etc/sysconfig/kubelet
#添加下面的配置
KUBELET_CGROUP_ARGS="--cgroup-driver=systemd"
KUBE_PROXY_MODE="ipvs"

4、设置开机启动（每个节点上都要执行）

systemctl enable kubelet

5、查看所需要的镜像

 kubeadm config images list --kubernetes-version 1.23.6

k8s.gcr.io/kube-apiserver:v1.23.6
k8s.gcr.io/kube-controller-manager:v1.23.6
k8s.gcr.io/kube-scheduler:v1.23.6
k8s.gcr.io/kube-proxy:v1.23.6
k8s.gcr.io/pause:3.7
k8s.gcr.io/etcd:3.5.3-0
k8s.gcr.io/coredns/coredns:v1.8.6

6、下载镜像，由于网络原因，从阿里云仓库地址下载，然后修改名称（每个节点上都要执行）

#创建脚本文件
vi pull.sh

脚本内容 

images=(
kube-apiserver:v1.23.6
kube-controller-manager:v1.23.6
kube-scheduler:v1.23.6
kube-proxy:v1.23.6
pause:3.7
etcd:3.5.3-0 
coredns:1.8.6
)
coreDnsName=coredns:1.8.6
for imageName in ${images[@]} ; do
docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/$imageName
if [ $imageName = $coreDnsName ]
then echo 'dns-------'
docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/$imageName k8s.gcr.io/coredns/coredns:v1.8.6
docker rmi registry.cn-hangzhou.aliyuncs.com/google_containers/$imageName
else echo 'other-------'
docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/$imageName k8s.gcr.io/$imageName
docker rmi registry.cn-hangzhou.aliyuncs.com/google_containers/$imageName
fi
done

#授权
chmod +x pull.sh
#执行
./pull.sh

7、初始化（仅在master节点执行即可）

kubeadm init \
--kubernetes-version=v1.23.6 \
--pod-network-cidr=10.244.0.0/16 \
--image-repository registry.aliyuncs.com/google_containers \
--service-cidr=10.96.0.0/12 \
--apiserver-advertise-address=192.168.139.176 #ip对应master的ip

 

8、创建文件（仅在master节点执行即可）

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

9、在其他两台从节点上执行如下命令

kubeadm join 192.168.139.176:6443 --token dmw7l9.f4pwa19mwi555gsi \
        --discovery-token-ca-cert-hash sha256:ec7b9c41c49801bfa7fb012672e1f32e0f8b6e040b67378b9db2007d744b7913 

注意：token过期时间为24小时，如果过期执行以下命令创建token

#创建token
kubeadm token create
#查看token
kubeadm token list

 获取证书hash值

openssl x509 -pubkey -in /etc/kubernetes/pki/ca.crt | openssl rsa -pubin -outform der 2>/dev/null | openssl dgst -sha256 -hex | sed 's/^.* //'

10、在master节点上查看节点信息

kubectl get nodes

11、安装网络插件

下载 kube-flannel.yml地址如下(tag=0.17.0版本)

          type: FileOrCreate

将该文件上传到master服务器 执行如下命令

kubectl apply -f kube-flannel.yml

注意上传完文件之后 使用如下命令检查一下文件

vi -b kube-flannel.yml

 如果显示^M等样式的文件 执行以下命令

sed -i 's/\r//g' kube-flannel.yml 

查看插件是否安装成功

kubectl get pods -n kube-system |grep flannel

12、查看节点状态（等待1分钟 左右）

kubectl get nodes

 显示ready此时k8s集群安装完成

注意：如果等待1分钟时候还是不行执行以下命令（每个节点）

vi /var/lib/kubelet/kubeadm-flags.env

删除 --network-plugin=cni

 重新启动

systemctl daemon-reload
systemctl restart kubelet

13、重置k8s

kubeadm reset
rm -rf /etc/cni/net.d
rm -rf $HOME/.kube/config
rm -rf /etc/kubernetes/

 14、查看日志

systemctl status kubelet -l #此处是L小写字母不是1
journalctl -xeu kubelet -l

四、k8s安装nginx

1、在master执行如下命令

kubectl create deployment nginx --image=nginx

2、暴露端口

kubectl expose deployment nginx --port=80 --type=NodePort

3、查看运行的服务

kubectl get pods,service

 4、查看pod运行情况

kubectl describe pod nginx-85b98978db-6vtdn

 可以查看运行在node1上

访问ip:30554端口

 5、常用指令

kubectl get pod -n kube-system -o wide #查看pod状态
kubectl get pods #查看正在运行的pod
kubectl describe pod nginx-85b98978db-6vtdn #查看正在运行的pod具体信息
kubectl get pods --all-namespaces  #查看所有pod的运行
kubectl get pod -n kube-system  
kubectl get pod -n kube-system -w  #监视

五、安装Dashboard

说明：下面的命令在master节点上执行

1、创建kubernetes-dashboard.yaml文件
