搭建k8s集群并在k8s上安装kubesphere

k8s：

基础配置（获取三台服务器）

方法一、使用一台Windows电脑创建三台centos虚拟机：

Windows 环境：

1. cpu：16个
2. 内存：16G
3. windows 10

vagrant 组合virtualbox 快速搭建虚拟机：

1. 下载最新版vagrant : Vagrant by HashiCorp (vagrantup.com)

2. 下载最新版virtualbox：Oracle VM VirtualBox

3. 之后进行搭建虚拟机： 由于我先创建好了，才做的笔记 请忽略这三台正在运行的机子

   1. 检查我们的 virtualbox 的网卡设置

   2. 之后进行全局设置一下我们的虚拟机的存放的位置：

   3. 来到我们保存vagrant 的文件的位置

   4. 打开cmd命令尽心初始化文件

      vagrant init centos/7
      

   5. 执行完上面的命令后，会在用户的家目录下生成Vagrantfile文件

   6. VagrantFile文件：

      Vagrant.configure("2") do |config|
      #遍历3次。生成3个
      (1..3).each do |i|
      config.vm.define "k8s-node#{i}" do |node|
      # 设置虚拟机的Box。指定本地的box文件
      node.vm.box = "centos/7"
      # 设置虚拟机的主机名
      node.vm.hostname="k8s-node#{i}"
      # 设置虚拟机的IP
      node.vm.network "private_network", ip: "192.168.56.#{99+i}",
      netmask: "255.255.255.0"
      # 设置主机与虚拟机的共享目录
      # node.vm.synced_folder "~/Documents/vagrant/share",
      "/home/vagrant/share"
      # VirtaulBox相关配置
      node.vm.provider "virtualbox" do |v|
      # 设置虚拟机的名称
      v.name = "k8s-node#{i}"
      # 设置虚拟机的内存大小
      v.memory = 4096
      # 设置虚拟机的CPU个数
      v.cpus = 4
      end
      end
      end
      end
      

4. 之后就开始操作

5. 由于我们要去远程下载centos/7 等待 试讲就会很长 所以我们可以直接先将文件下载下来 去 centos 官网下载 centos镜像（按理说会自动下载的，但是我的找不到）

   1. 官网地址：Download (centos.org)

   2. 选择vagrant 的

   3. 下载好后放入同级目录下即可

6. 之后将centos/7 添加进 vagrant中

   vagrant box add centos/7 D:\developsoft\CentOS-7-x86_64-Vagrant1905_01.VirtualBox.box
   

7. 来到安装目录下 （确保启动 virtualbox ） 打开cmd命令框 输入命令

   vagrant up
   

8. . 进行虚拟机的创建 ：

修改访问 设置ssh也可以访问：

使用vagrant 的ssh 进行连接 即可 使用

vagrant ssh 虚拟机名称

之后使用指令进行登录

su root

vagrant

之后进入文件 进行修改：

vi /etc/ssh/sshd_config

之后重启虚拟机：

service sshd restart

之后其他三台流水线式 设置即可 设置完后 我们就可以使用 XShell 来进行连接了：

配置网络（三台虚拟机的私有网络）：

首先将三台虚拟机的电源全部关闭：

1. 来到 vir 工具中进行设置网络创建一个net 网络

2. 选择net 网络：

3.

4. 之后重启虚拟机 在检查每个虚拟机使用的网路地址是否还是相同，之后就可以进行 ping 一下我们 的网络查看网络是否可以ping的通

5. 之后把每个虚拟机的防火墙都给关闭即可

   systemctl stop firewalld
   systemctl disable firewalld
   

之后查看 我们的三台服务器使用的是那个网卡 因为笔记本电脑都是双网卡模式

ip route show

如果三个服务器的默认网卡地址都为一样的就需要进行修改

不一样就不用了哦

方法二、去qingCloud申请三个服务器：

来到青云 申请三个公网ip：

创建vpc私有网络：

之后就直接创建即可 下面的都默认

创建三台服务器

要创建三台哦 当然两台也行 只是效果不是很好 ：

之后使用xshell连接上

配置前置环境：

安装docker：

sudo yum remove docker*
sudo yum install -y yum-utils

#配置docker的yum地址
sudo yum-config-manager \
--add-repo \
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo


#安装指定版本
sudo yum install -y docker-ce-20.10.7 docker-ce-cli-20.10.7 containerd.io-1.4.6

#	启动&开机启动docker
systemctl enable docker --now

# docker加速配置
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://82m9ar63.mirror.aliyuncs.com"],
  "exec-opts": ["native.cgroupdriver=systemd"],
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "100m"
  },
  "storage-driver": "overlay2"
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

重新设置 ：

为每个机器设置名称 好方便下面操作（三台服务器都要设置）：

#设置每个机器自己的hostname
hostnamectl set-hostname xxx

eg:
作为主节点的服务器设置为：  hostnamectl set-hostname master
其余两台工作服务器  
第一台 ：hostnamectl set-hostname node1
第一台 ：hostnamectl set-hostname node2

安装基本环境：

# 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

安装kubelet、kubeadm、kubectl

#配置k8s的yum源地址
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
EOF


#安装 kubelet，kubeadm，kubectl
sudo yum install -y kubelet-1.20.9 kubeadm-1.20.9 kubectl-1.20.9

#启动kubelet
sudo systemctl enable --now kubelet

#所有机器配置master域名
echo "10.13.111.175  k8s-master" >> /etc/hosts

注意点需要更改的地点为： 更换为 自己master 的主机地址 是vpc虚拟网络的 不是公网ip

#所有机器配置master域名
echo "10.13.111.175  k8s-master" >> /etc/hosts

配置完后就进行ping 一下 看是否都能找到：

ping k8s-master

arm架构的k8s 阿里源：
这个是针对服务器的系统，如果是arm系统的服务器才需要配置这个镜像地址，否者直接跳过者一步。

cat <<EOF | sudo tee /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=http://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-aarch64/
enabled=1

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
EOF

初始化master 节点：

kubeadm init \
--apiserver-advertise-address=10.13.111.175 \
--control-plane-endpoint=k8s-master \
--image-repository registry.cn-hangzhou.aliyuncs.com/lfy_k8s_images \
--kubernetes-version v1.20.9 \
--service-cidr=10.96.0.0/16 \
--pod-network-cidr=192.168.0.0/16

更改地方为： 还是将地址改为master 的主机地址

--apiserver-advertise-address=10.13.111.175 \

表示撤销初始化master节点（错误或者失败时使用）

sudo kubeadm reset

记录关键信息：

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 k8s-master:6443 --token yodfqt.bz8x38s644631ek6 \
    --discovery-token-ca-cert-hash sha256:198d4c123c7772ed3956d82fa8d556cd6e8109283441c4a5feaaede7d6440967 \
    --control-plane 

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

kubeadm join k8s-master:6443 --token yodfqt.bz8x38s644631ek6 \
    --discovery-token-ca-cert-hash sha256:198d4c123c7772ed3956d82fa8d556cd6e8109283441c4a5feaaede7d6440967 

之后再master节点上执行： 也就是关键信息中的

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

安装网络插件：

curl https://docs.projectcalico.org/v3.20/manifests/calico.yaml -O

kubectl apply -f calico.yaml

加入worker 节点：

在子节点 也就是node1和node2中执行 这个命令是关键信息中的

kubeadm join k8s-master:6443 --token yodfqt.bz8x38s644631ek6 \
    --discovery-token-ca-cert-hash sha256:198d4c123c7772ed3956d82fa8d556cd6e8109283441c4a5feaaede7d6440967 

nfs文件系统

# 在每个机器。
yum install -y nfs-utils

之后再master节点：

# 在master 执行以下命令 
echo "/nfs/data/ *(insecure,rw,sync,no_root_squash)" > /etc/exports


# 执行以下命令，启动 nfs 服务;创建共享目录
mkdir -p /nfs/data


# 在master执行
systemctl enable rpcbind
systemctl enable nfs-server
systemctl start rpcbind
systemctl start nfs-server

# 使配置生效
exportfs -r


#检查配置是否生效
exportfs

在子节点 也就是node1和node2节点进行 ：

showmount -e 10.0.2.15

mkdir -p /nfs/data

mount -t nfs 10.0.2.15:/nfs/data /nfs/data

注意点： 修改地址：改为 master节点的地址

配置默认存储：

在master节点上

vi sc.yaml

粘贴以下内容

安装KubeSphere

https://kubesphere.com.cn/

1、下载核心文件

如果下载不到，请复制附录的内容

wget https://github.com/kubesphere/ks-installer/releases/download/v3.1.1/kubesphere-installer.yaml

wget https://github.com/kubesphere/ks-installer/releases/download/v3.1.1/cluster-configuration.yaml

2、修改cluster-configuration （重要）

也就是将cluster-configuration.yaml 文件中的所有false 改为true （除了 metrics-server ）还有ip地址 改为master，指定网络

具体可以参照附录中的文件进行：

执行安装：

kubectl apply -f kubesphere-installer.yaml

kubectl apply -f cluster-configuration.yaml

查看进度：

kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{
    
    .items[0].metadata.name}') -f

如果是青云记得开放端口：

访问任意机器的 30880端口

账号 ： admin

密码 ： P@88w0rd

解决etcd监控证书找不到问题

根据情况来执行：否则适得其反

kubectl -n kubesphere-monitoring-system create secret generic kube-etcd-client-certs  --from-file=etcd-client-ca.crt=/etc/kubernetes/pki/etcd/ca.crt  --from-file=etcd-client.crt=/etc/kubernetes/pki/apiserver-etcd-client.crt  --from-file=etcd-client.key=/etc/kubernetes/pki/apiserver-etcd-client.key

安装完成效果：
