背景
CentOS 7 官方支持和更新已于2024年6月30日结束。这意味着CentOS 7 不再接受官方的更新和补丁。并且官方推荐用户迁移到新的操作系统；而转移到Debian的优势有：
- 更加成熟的软件包管理系统：Debian 的包管理系统是 APT（Advanced Package Tool），相对于 CentOS 的 YUM 或 DNF，它更加成熟稳定，并提供更好的软件包管理功能。
- 更加完整的社区支持：Debian 有一个更加庞大和活跃的用户社区，可以提供更广泛的支持和解决方案。
- 更加精简的系统：Debian 在默认安装时通常比 CentOS 更加精简，系统资源占用更少。
环境准备
| 说明 | 配置 |
|---|---|
| 系统 | Debian 12.6 |
| CPU | 4核及以上 |
| 内存 | 8G及以上 |
| 机器数量 | 最少两台（一主节点一工作节点） |
安装k8s前准备（安装容器 Containerd）【主节点+工作节点】
自 1.24 版起，Dockershim 已从 Kubernetes 项目中移除；要求使用符合容器运行时接口（CRI）的运行时；可以切换到使用containerd或CRI-O；
所有节点上配置如下的核心参数
cat <<EOF | sudo tee /etc/modules-load.d/containerd.conf
overlay
br_netfilter
EOF
#运行
sudo modprobe overlay
sudo modprobe br_netfilter
## 确保 IP 转发被启用
echo "net.ipv4.ip_forward=1" | sudo tee -a /etc/sysctl.conf
echo "net.bridge.bridge-nf-call-ip6tables=1" | sudo tee -a /etc/sysctl.conf
echo "net.bridge.bridge-nf-call-iptables=1" | sudo tee -a /etc/sysctl.conf
#运行如下命令，以使上面的更改生效
# sudo sysctl -p
sudo sysctl --system

K8s安装
安装方式1：安装 (官网)Kubernetes
更新 apt 包索引
sudo apt-get update
sudo apt install gnupg gnupg2 curl software-properties-common -y
# apt-transport-https 可能是一个虚拟包（dummy package）；如果是的话，你可以跳过安装这个包
sudo apt-get install -y apt-transport-https ca-certificates curl gpg
#下载用于 Kubernetes 软件包仓库的公共签名密钥。所有仓库都使用相同的签名密钥，因此你可以忽略URL中的版本
# 如果 `/etc/apt/keyrings` 目录不存在，则应在 curl 命令之前创建它，请阅读下面的注释。
# sudo mkdir -p -m 755 /etc/apt/keyrings
curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.28/deb/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-apt-keyring.gpg
#添加适当的 Kubernetesapt存储库。请注意，此存储库仅包含适用于 Kubernetes 1.28 的软件包；
#对于其他 Kubernetes 次要版本，您需要更改 URL 中的 Kubernetes 次要版本以匹配所需的次要版本（您还应该检查您正在阅读的文档是否适用于您计划安装的 Kubernetes 版本）
#在低于 Debian 12 和 Ubuntu 22.04 的发行版本中，`/etc/apt/keyrings` 默认不存在。 应在 curl 命令之前创建它
# 此操作会覆盖 /etc/apt/sources.list.d/kubernetes.list 中现存的所有配置。
echo 'deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] https://pkgs.k8s.io/core:/stable:/v1.28/deb/ /' | sudo tee /etc/apt/sources.list.d/kubernetes.list
#更新 `apt` 包索引，安装 kubelet、kubeadm 和 kubectl，并锁定其版本
sudo apt-get update
sudo apt-get install -y kubelet kubeadm kubectl
sudo apt-mark hold kubelet kubeadm kubectl
安装方式2：安装 (阿里云镜像-本教程使用该种方式)Kubernetes 【主节点+工作节点】
sudo apt-get update
sudo apt install gnupg gnupg2 curl software-properties-common -y
curl -s https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | sudo apt-key add -
## 添加 Kubernetes 仓库
echo "deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list
## 更新软件包列表
sudo apt-get update
## 安装 kubeadm、kubelet 和 kubectl
sudo apt-get install -y kubelet=1.28.2-00 kubeadm=1.28.2-00 kubectl=1.28.2-00
sudo apt-mark hold kubelet kubeadm kubectl
初始化集群：【主节点】
sudo kubeadm init --pod-network-cidr=10.244.0.0/16 --service-cidr=10.96.0.0/12 --apiserver-advertise-address=192.168.10.137 --image-repository=registry.aliyuncs.com/google_containers --kubernetes-version=v1.28.2
| 参数 | 说明 |
|---|---|
| –apiserver-advertise-address | 主节点的内网ip地址（需要改成实际主节点地址） |
| –image-repository | 镜像仓库 |
| –kubernetes-version | k8s版本(版本与安装的一致) |
| –service-cidr 和 --pod-network-cidr | 网段不重复即可 （可以不修改） |
注意：每个环境命令有可能不一样，以操作指令的系统为准，将上图两处圈红的指令分别在主节点和工作节点执行；执行步骤参照主节点执行完命令需要执行、注册节点执行对应的指令
主节点执行完命令需要执行【仅限主节点】
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
注册节点【工作节点】
kubeadm join 172.22.189.160:6443 --token b79kr2.3216h48f8g6h15g6 \
--discovery-token-ca-cert-hash sha256:fc5eaa437694e920dd8813f16adc0bf08c5676a983cf1e768c6fe57c10d45211
查看节点
kubectl get nodes
安装网络插件【主节点】
- 官网地址：https://docs.tigera.io/calico/3.26/getting-started/kubernetes/quickstart
- 对应yaml文件也可以在文章的最后复制然后再上传服务器
- 安装 Tigera Calico operator
kubectl create -f https://raw.githubusercontent.com/projectcalico/calico/v3.26.4/manifests/tigera-operator.yaml
#查看状态
kubectl get ns
#查看空间 tigera-operator 等待到pod处理运行状态再执行后续指令
kubectl get pods -n tigera-operator
- 通过创建必要的自定义资源来安装 Calico
wget https://raw.githubusercontent.com/projectcalico/calico/v3.26.4/manifests/custom-resources.yaml
#替换ip
sed -i 's/192.168.0.0/10.244.0.0/' custom-resources.yaml
##安装Calico
kubectl create -f custom-resources.yaml
#检查状态
kubectl get pods -n calico-system
kubectl get pods -n kube-system -o wide
#查看pos
kubectl describe pod [pod-name] -n kube-system
安装好网络插件的节点信息
异常问题修复
missing required cgroups: cpu
解决方法1：修改/etc/default/grub
vim /etc/default/grub
## 添加一行
GRUB_CMDLINE_LINUX="cgroup_enable=cpu"
#运行update-grub2
update-grub2
#重启机器生效
reboot
解决方法2：修改/boot/cmdline.txt
vim /boot/cmdline.txt
#加入下面两句
cgroup_enable=cpu
cgroup_cpu=1
#重启服务
reboot
搭建第一个K8S应用
创建deployment demo-nginx（Pod控制器的一种）
kubectl create deployment demo-nginx --image=nginx:1.23.0
查看deployment和pod
暴露80端口，创建service
kubectl expose deployment demo-nginx --port=80 --type=NodePort
访问应用
在浏览器访问, 工作节点开放端口32644，访问工作节点ip：32644（网络安全组记得开放32644端口）
master、node节点访问这个 开放的端口都可以
