情况说明

• 前段时间呢，为了学习使用k8s买了3台服务器，当然为了省钱。。，于是就买了腾讯云的学生优惠服务器，由于是3个账号分别购买，于是就。。。只能公网部署，中间遇到了好多好多坑，但是最终还是一个坑一个坑爬出来了，特此记录一下，哪些不小心买了非内网部署的小伙伴们可以参考下。

服务器配置

1. 三台4核8g的
2. 学习环境的话，如果仅仅只是搭建k8s集群，上面在运行几个springboot项目应该是够用的
3. 如果要用kubesphere的话，会有点儿卡
4. 纯学习的话，其实可以买按时间计费的服务器

一些链接

1. k8s官网链接：https://kubernetes.io/
2. kubesphere官网：https://kubesphere.com.cn/
3. 内网部署的话，可以参考尚硅谷的：尚硅谷内网部署

部署步骤

1、 每台机器设置hostname

# 三台机器一次运行下面的命令， 设置不同的hostname
# 语法格式：hostnamectl set-hostname xxx
hostnamectl set-hostname master
hostnamectl set-hostname slave1
hostnamectl set-hostname slave2

2、 基础环境

# 将 SELinux 设置为 permissive 模式（相当于将其禁用）
sudo setenforce 0
sudo sed -i 's/^SELINUX=enforcing$/SELINUX=permissive/' /etc/selinux/config

#关闭swap
swapoff -a  
sed -ri 's/.*swap.*/#&/' /etc/fstab

#允许 iptables 检查桥接流量
cat <<EOF | sudo tee /etc/modules-load.d/k8s.conf
br_netfilter
EOF

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

3、创建虚拟网卡（这里是公网部署的关键）

# 所有主机都要创建虚拟网卡，并绑定对应的公网 ip
# 临时生效，重启会失效
ifconfig eth0:1 <你的公网IP>
 
# 永久生效
cat > /etc/sysconfig/network-scripts/ifcfg-eth0:1 <<EOF
BOOTPROTO=static
DEVICE=eth0:1
IPADDR=<你的公网IP>
PREFIX=32
TYPE=Ethernet
USERCTL=no
ONBOOT=yes
EOF
# 设置后重启网卡
sudo systemctl restart network

4、所有机器添加域名映射

#所有机器添加master域名映射 写自己ip  这里的域名要和设置的hostname对应
echo "110.40.155.237 master" >> /etc/hosts
echo "43.142.47.211  slave1" >> /etc/hosts
echo "43.138.55.127  slave2" >> /etc/hosts

5、所有机器安装kubelet、kubeadm、kubectl

# 设置安装源
cat <<EOF | sudo tee /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=http://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=http://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg
   http://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
exclude=kubelet kubeadm kubectl
EOF

#进行安装
sudo yum install -y kubelet-1.20.9 kubeadm-1.20.9 kubectl-1.20.9 --disableexcludes=kubernetes

#将kubelet 命令添加到systemctl中 
sudo systemctl enable --now kubelet

6、所有机器安装kubeadm引导集群

sudo tee ./images.sh <<-'EOF'
#!/bin/bash
images=(
kube-apiserver:v1.20.9
kube-proxy:v1.20.9
kube-controller-manager:v1.20.9
kube-scheduler:v1.20.9
coredns:1.7.0
etcd:3.4.13-0
pause:3.2
)
for imageName in ${images[@]} ; do
docker pull registry.cn-hangzhou.aliyuncs.com/lfy_k8s_images/$imageName
done
EOF

# 添加执行权限 并执行images.sh中的命令 去下载镜像
chmod +x ./images.sh && ./images.sh

7、修改kubelet启动参数文件（每台机器都需要执行） （很重要）

# 此文件安装kubeadm后就存在了
vim /usr/lib/systemd/system/kubelet.service.d/10-kubeadm.conf
 
# 注意，这步很重要，如果不做，节点仍然会使用内网IP注册进集群，通过修改这里 可以让每个几点以公网ip注册到集群中
# 在末尾添加参数 --node-ip=公网IP
ExecStart=/usr/bin/kubelet $KUBELET_KUBECONFIG_ARGS $KUBELET_CONFIG_ARGS $KUBELET_KUBEADM_ARGS $KUBELET_EXTRA_ARGS --node-ip=<公网IP>

8、初始化master节点（只在主节点进行）

8.1 添加kubeadm-config.yaml配置文件

cat > kubeadm-config.yaml <<EOF
apiVersion: kubeadm.k8s.io/v1beta2
kind: ClusterConfiguration
kubernetesVersion: v1.20.9
apiServer:
  certSANs: 
  - master        #请替换为hostname
  - 110.41.115.236   #请替换为公网IP
  - 10.0.4.7   #请替换为私网IP
  - 10.96.0.1
controlPlaneEndpoint: 110.41.115.236:6443 #替换为公网IP
imageRepository: registry.cn-hangzhou.aliyuncs.com/lfy_k8s_images
networking:
  #pod网络层 这里需要根据你使用的网络插件来更换，例如calico就用192.168.0.0/16，falnnel需要换成10.244.0.0/16
  podSubnet: 10.244.0.0/16
  #service网络层
  serviceSubnet: 10.96.0.0/12
--- 
apiVersion: kubeproxy-config.k8s.io/v1alpha1
kind: KubeProxyConfiguration
featureGates:
  SupportIPVSProxyMode: true
mode: ipvs
EOF

8.2 执行初始化命令

#如果失败了，就在init命令最后添加-v=10来查看什么错误。
#并通过删除原有安装
kubeadm init --config=kubeadm-config.yaml
#kubeadm init -v=10 --config=kubeadm-config.yaml
# 如果安装失败需要重新安转 删除原有安装
kubeadm reset
rm -rf /root/.kube/
sudo rm -rf /etc/kubernetes/
sudo rm -rf /var/lib/kubelet/
sudo rm -rf /var/lib/dockershim
sudo rm -rf /var/run/kubernetes
sudo rm -rf /var/lib/cni
sudo rm -rf /var/lib/etcd
sudo rm -rf /etc/cni/net.d

8.3 成功之后

8.3.1 显示的内容

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/

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 110.40.225.236:6443 --token 0tb7mi.q6q1cwt7mv11pxa0 \
    --discovery-token-ca-cert-hash sha256:b69907b021012f8a2968afb73872b782e1b753385d4ccedc71e94a79fbed3e80 \
    --control-plane

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

kubeadm join 133.40.222.236:6443 --token 0tb7mi.q6q1cwt7mv11pxa0 \
    --discovery-token-ca-cert-hash sha256:b69907b021012f8a2968afb73872b782e1b753385d4ccedc71e94a79fbed3e80

8.3.2 第一步

#需要执行这里 只在master
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

8.3.3 第二步

#如果是root用户就执行这里 只在master
export KUBECONFIG=/etc/kubernetes/admin.conf

8.4 修改kube-apiserver参数 (只在master)

# 修改两个信息，添加--bind-address和修改--advertise-address

8.5 安装网络组件 使用 flanel （calico没成功。。。）

8.5.1 下载flannel配置文件

8.5.3 创建网络插件

kubectl apply -f kube-flannel.yml

8.6 从节点加入

8.6.1 加入命令

# 这个命令是有时效性的 24小时 
# 第二次加入先强制重置  kubeadm reset -f
kubeadm join 123.45.165.236:6443 --token 8z98g4.p7eafjdkcaqd279a \
    --discovery-token-ca-cert-hash sha256:0f6891168a726c265528355ca932ae74769bfef1e0f7d0f89b089a428eda9829

8.6.2 使用命令检查（在主节点）

# 查看pod
kubectl get pods -A
# 查看节点及其ip
kubectl get nodes -o wide
# 查看节点状态
journalctl -f -u kubelet

8.6.3 重新生成加入命令 （在主节点）

kubeadm token create --print-join-command

9、部署控制台

9.1 拉取配置

#kubernetes官方提供的可视化界面
#https://github.com/kubernetes/dashboard

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.3.1/aio/deploy/recommended.yaml

9.2 配置内容（如果拉不下来，可以直接用这个，也可以到github上下载）

9.4 设置访问端口

#type: ClusterIP 改为 type: NodePort

# 获取控制台运行所在端口  31639 访问的话  就ip  + 端口
kubectl get svc -A |grep kubernetes-dashboard

9.5 创建访问账号

#创建访问账号，准备一个yaml文件； vi dash.yaml

9.6 加载配置文件 生成访问令牌

kubectl apply -f dash.yaml
#获取访问令牌
kubectl -n kubernetes-dashboard get secret $(kubectl -n kubernetes-dashboard get sa/admin-user -o jsonpath="{.secrets[0].name}") -o go-template="{{.data.token | base64decode}}"

#令牌
