Kubernetes从零开始手动安装和配置

Kubernetes k8s DevOps CICD 安装教程

本文将详细介绍如何从零开始手动搭建Kubernetes集群环境。我们将一步一步展示整个过程，包括环境准备、软件版本选择、详细步骤和配置说明。

服务器要求

Kubernetes版本

版本: v1.22.15

节点要求

节点数: 至少3台
CPU: 至少2个
内存: 至少2G

修改时区

某些系统的时区可能不匹配，需要进行修改：

timedatectl set-timezone Asia/Shanghai

环境说明

系统类型	IP地址	节点角色	CPU	内存	主机名
CentOS-7.9	192.168.200.11	master	>=2	>=2G	cluster1
CentOS-7.9	192.168.200.22	master,worker	>=2	>=2G	cluster2
CentOS-7.9	192.168.200.33	worker	>=2	>=2G	cluster3

使用Vagrant搭建虚拟机节点

Vagrant: 最新版本
VirtualBox: 7.0
vagrant-vbguest: 0.21 (用于挂载host和guest同步目录)

vagrant plugin install vagrant-vbguest --plugin-version 0.21

Vagrantfile配置

# -*- mode: ruby -*-
# vi: set ft=ruby :

nodes = [
  {
    :name => "cluster1",
    :eth1 => "192.168.200.11",
    :mem => "4096",
    :cpu => "2"
  },
  {
    :name => "cluster2",
    :eth1 => "192.168.200.22",
    :mem => "4096",
    :cpu => "2"
  },
  {
    :name => "cluster3",
    :eth1 => "192.168.200.33",
    :mem => "4096",
    :cpu => "2"
  },
]

Vagrant.configure("2") do |config|
  config.vm.box = "centos/7"

  nodes.each do |opts|
    config.vm.define opts[:name] do |config|
      config.vm.hostname = opts[:name]

      config.vm.provider "virtualbox" do |v|
        v.customize ["modifyvm", :id, "--memory", opts[:mem]]
        v.customize ["modifyvm", :id, "--cpus", opts[:cpu]]
      end

      config.vm.synced_folder "../share", "/vagrant_data"
      config.vm.network :public_network, ip: opts[:eth1]
    end
  end
end

系统设置(所有节点)

需要root权限

设置hostname (/etc/hosts)
安装依赖包

yum update -y
yum install -y socat conntrack ipvsadm ipset jq sysstat curl iptables libseccomp yum-utils

关闭防火墙, selinux, swap, 重置 iptables

# 关闭selinux
setenforce 0
sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config

# 关闭防火墙
systemctl stop firewalld && systemctl disable firewalld

# 设置iptables规则
iptables -F && iptables -X && iptables -F -t nat && iptables -X -t nat && iptables -P FORWARD ACCEPT

# 关闭swap
vi /etc/fstab
# 永久禁用注释掉swap
#/swapfile none swap defaults 0 0
# 临时禁用
swapoff -a

# 关闭dnsmasq
service dnsmasq stop && systemctl disable dnsmasq

Kubernetes参数设置

cat > /etc/sysctl.d/kubernetes.conf <<EOF
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_nonlocal_bind = 1
net.ipv4.ip_forward = 1
vm.swappiness = 0
vm.overcommit_memory = 1
EOF

sysctl -p /etc/sysctl.d/kubernetes.conf

配置免密登录

# 生成公秘钥对, 如果没有可用的
ssh-keygen -t rsa

# 查看公钥内容
cat ~/.ssh/id_rsa.pub

# 每一台节点机器上配置
echo "<pubkey content>" >> ~/.ssh/authorized_keys

配置IP映射(每个节点)

cat > /etc/hosts <<EOF
192.168.200.11 cluster1
192.168.200.22 cluster2
192.168.200.33 cluster3

生成证书

准备工作

安装cfssl：

wget https://pkg.cfssl.org/R1.2/cfssl_linux-amd64 -O /usr/local/bin/cfssl
wget https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64 -O /usr/local/bin/cfssljson
chmod +x /usr/local/bin/cfssl*

生成根证书

创建根证书配置文件：

cat > ca-config.json <<EOF
{
  "signing": {
    "default": {
      "expiry": "876000h"
    },
    "profiles": {
      "kubernetes": {
        "usages": ["signing", "key encipherment", "server auth", "client auth"],
        "expiry": "876000h"
      }
    }
  }
}
EOF

cat > ca-csr.json <<EOF
{
  "CN": "Kubernetes",
  "key": {
    "algo": "rsa",
    "size": 2048
  },
  "names": [
    {
      "C": "US",
      "L": "Portland",
      "O": "Kubernetes",
      "OU": "CA",
      "ST": "Oregon"
    }
  ]
}
EOF

生成证书和私钥：

cfssl gencert -initca ca-csr.json | cfssljson -bare ca

输出文件：

ca.pem
ca.csr
ca-key.pem

生成其他证书

按照类似步骤生成admin、kubelet、kube-controller-manager、kube-proxy、kube-scheduler、kube-apiserver、Service Account、proxy-client等证书。

部署ETCD集群

配置etcd证书文件：

mkdir -p /etc/etcd /var/lib/etcd
chmod 700 /var/lib/etcd
cp ca.pem kubernetes-key.pem kubernetes.pem /etc/etcd/

配置etcd.service文件：

ETCD_NAME=$(hostname -s)
ETCD_IP=192.168.200.11
ETCD_NAMES=(cluster1 cluster2 cluster3)
ETCD_IPS=(192.168.200.11 192.168.200.22 192.168.200.33)

配置kubectl

kubectl用于管理Kubernetes集群的客户端工具。

mkdir ~/.kube/
mv ~/admin.kubeconfig ~/.kube/config
kubectl get nodes

授权apiserver调用kubelet API，在执行kubectl exec/run/logs时apiserver会转发到kubelet：

kubectl create clusterrolebinding kube-apiserver:kubelet-apis --clusterrole=system:kubelet-api-admin --user kubernetes

部署Kubernetes Worker Node

在每个节点上部署：

kubelet
kube-proxy
container runtime
cni
nginx-proxy

Container Runtime (containerd)

VERSION=1.4.3
wget https://github.com/containerd/containerd/releases/download/v${VERSION}/cri-containerd-cni-${VERSION}-linux-amd64.tar.gz
tar -xvf cri-containerd-cni-${VERSION}-linux-amd64.tar.gz
cp etc/crictl.yaml /etc/
cp etc/systemd/system/containerd.service /etc/systemd/system/
cp -r usr /

containerd配置文件

mkdir -p /etc/containerd
containerd config default > /etc/containerd/config.toml

启动containerd

systemctl enable containerd
systemctl start containerd
systemctl status containerd

配置kubelet

准备配置文件：

mkdir -p /etc/kubernetes/ssl/

替换cluster-ip并应用：

sed -i "s/\${COREDNS_CLUSTER_IP}/${COREDNS_CLUSTER_IP}/g" coredns.yaml
kubectl apply -f coredns.yaml

通过这些优化，文档不仅更易于阅读，也更有可能在搜索引擎中获得更高的排名。
