安装步骤
安装前准备
关闭防火墙
执行下面命令永久关闭防火墙：
# 关闭防火墙
sudo systemctl disable --now ufw
# 查看防火墙的状态
sudo systemctl status ufw# 关闭防火墙
sudo systemctl disable --now ufw
root@k8s-master-10:~# sudo systemctl disable --now ufw
Synchronizing state of ufw.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install disable ufw
Removed /etc/systemd/system/multi-user.target.wants/ufw.service.

sudo timedatectl set-timezone Asia/Shanghai
# 重启时间同步服务
sudo systemctl restart systemd-timesyncd.service
# 确保时间同步服务正常运动 查看时间服务的状态

需要关闭所有 swap 分区，可以修改 /etc/fstab 文件：
sudo vi /etc/fstab 永久关闭 swap 分区
注释掉带 swap 的这一行上面是永久关闭,下面可以执行这行命令临时关闭

sudo swapoff -a
# 查看 swap 是否已经被关闭
free -h sudo vi /etc/fstab 永久关闭 swap 分区 vim /etc/fstab

# 可以通过下面命令进行下载：
curl -LO https://github.com/containerd/containerd/releases/download/v1.7.13/cri-containerd-cni-1.7.13-linux-amd64.tar.gz
# 然后解压到根目录：

# 然后可以通过下面这行命令查看安装的版本：
containerd -v
# 同步命令

1.大概在65行位置修改 sandbox_image 值为 registry.aliyuncs.com/google_containers/pause:3.9
2. 大概在137行位置将 SystendCgroup 的值修改为 true

# SCP同步服务 以下两条命令在包含 cri-containerd-cni-1.7.14-linux-amd64.tar.gz 这个文件的主机执行

scp -r cri-containerd-cni-1.7.14-linux-amd64.tar.gz root@172.18.26.143:/root
SCP命令的基本语法： scp可以实现跨主机复制
$ scp [option] /path/to/source /path/to/source/file-这是打算复制到远程主机源文件
user@server-IP: -这是远程系统的用户名和 IP 地址。请注意 IP 地址后面加冒号
命令解释
'scp' 可以跨主机复制
'-r' -此选项递归复制目录及其内容
'-c'-这会在复制文件中压缩文件或者目录
'-p'-小写p 保留文件的访问和修改时间
'-P'-大写P 如果默认SSH端口不是22，则使用此选项指定 SSH 端口

# 配置文件
sudo vim /etc/containersd/config.toml#### containerd默认的配置文件 /etc/containerd/config.toml 参数说明如下：
##### version=2 : 这个是新版本基本默认的选项
##### root : containerd 保存元数据的地方。
##### state : containerd 的状态目录，重启数据就会刷新，就一个临时目录
##### address : 这个指的是 containerd 监听的套接字
##### plugins : 其中 sandbox_image 配置的是 cni 的插件，以及配置的 cni 的二进制目录和初始化目录；还有配置的私有库的地址，证书，访问的用户密码
##### path : containerd 的二进制文件路径
##### interval : containerd 重启的时间间隔
##### runtime : 这部分配置需要的运行时
##### runc , containerd-shim 这个垫片可以选择用或者不用
##### containerd 的 service 文件
##### 由于我们下载的 containerd 压缩包中包含一个 etc/systemd/system/contained.service 的文件，这样我们就可以通过 systemd 来配置 containerd 作为守护进程运行了## 安装 Kubernetes

[kubelet-finalize] Updating "/etc/kubernetes/kubelet.conf" to point to a rotatable kubelet client certificate and key
[addons] Applied essential addon: CoreDNS
[addons] Applied essential addon: kube-proxy
Your Kubernetes control-plane has initialized successfully!
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
Alternatively, if you are the root user, you can run:
export KUBECONFIG=/etc/kubernetes/admin.conf
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/
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join 172.18.26.152:6443 --token ow4k1a.s9yjp1pcid7u5qz5 \
--discovery-token-ca-cert-hash sha256:ebe3d1ebb48c9d474d948d67589d0075b7257b11342d8c8d1baa9930b1976878
root@k8s-master-10:~#
执行如图：
接下来通过下面命令初始化集群(注意修改主节点IP地址和版本等)：
sudo kubeadm init \
--apiserver-advertise-address=172.18.8.150 \
--image-repository=registry.aliyuncs.com/google_containers \
--kubernetes-version=1.28.7 \
--service-cidr=10.96.0.0/12 \
--pod-network-cidr=100244.0.0/16 \
--cri-socket=unix:///run/containerd/containerd.sock执行结果如下：
首先在本机上执行这三行命令：
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config然后在所有工作节点上执行这行命令(注意修改为自己的 token), 注意后面拼接上 --cri-socket=unix:///var/run/containerd/containerd.sock 参数：
以下命令是在任意数量的工作节点执行(目的是让节点和主节点建立联系)
sudo kubeadm join 172.18.8.150:6443 --token kxz9ng.mhm3zut1x80phcsd \
--discovery-token-ca-cert-hash sha256:f.... \
--cri-socket=unix:///run/containerd/containerd.sock然后可以通过命令在主节点上查看所有节点：(在主节点执行下面这条命令 打印各节点详细信息)
kubectl get nodes -o wide

安装 calico 网络插件
该步骤依照官网，calico官网地址：
https://docs.tigera.io/calico/latest/getting-started/kubernetes/quickstart
安装 Tigera Calico 操作符和自定义资源定义：
# 这条命令在主节点执行
kubectl create -f https://raw.githubusercontent.com/projectcalico/calico/v3.27.2/manifests/tigera-operator.yaml
可以看到创建成功：
# 查看资源创建情况 kubectl get all -o wide -n tigera-operator
接下来需要安装必须的客户端资源，因为我们 pod 的网段与 calico 官网不相同，所以先将这个文件下载下来然后更改一下网段地址：
# 下载客户端资源文件(在主节点执行)
curl -LO https://raw.githubusercontent.com/projectcalico/calico/v3.27.2/manifests/custom-resources.yaml
# 修改 pod 的网段地址 cat custom-resources.yaml
sed -i 's/cidr: 192.168.0.0/cidr: 10.244.0.0/g' custom-resources.yaml然后可以看修改成功：
最后根据这个文件创建资源，执行下面这行命令：
kubectl create -f custom-resources.yaml
# 创建成功然后获取一下
watch kubectl get all -o wide -n calico-system
watch kubectl get pods -n calico-system # 官网
# 官网复制
kubectl create -f https://raw.githubusercontent.com/projectcalico/calico/v3.27.2/manifests/custom-resources.yaml可以看到创建成功：

kubectl controls the Kubernetes cluster manager.
Find more information at: https://kubernetes.io/docs/reference/kubectl/
Basic Commands (Beginner):
create Create a resource from a file or from stdin
expose Take a replication controller, service, deployment or pod and expose it as a new Kubernetes service
run Run a particular image on the cluster
set Set specific features on objects
Basic Commands (Intermediate):
explain Get documentation for a resource
get Display one or many resources
edit Edit a resource on the server
delete Delete resources by file names, stdin, resources and names, or by resources and label selector
Deploy Commands:
rollout Manage the rollout of a resource
scale Set a new size for a deployment, replica set, or replication controller
autoscale Auto-scale a deployment, replica set, stateful set, or replication controller

部署应用
将会部署一个 nginx 应用，并以 NodePort 形式暴露此 nginx.创建一个 nginx-deploy.yaml 文件。文件内容如下：
vim nginx-deploy.yaml (在主节点执行)
kubectl apply -f nginx-deploy.yaml
# 创建如下
deployment.apps/nginx-deploy created
service/nginx-syc created
# 获取
kubectl get all -o wide
# 直接访问
curl 10.100.140.66
# 获取节点
kubectl get node -o wide下面是 nginx-deploy.yaml
root@k8s-master-10:~# cat nginx-deploy.yaml
