二进制部署k8s集群

1、安装要求

在开始之前，部署 Kubernetes 集群机器需要满足以下几个条件：

一台或多台机器，操作系统 CentOS7
硬件配置：2GB 或更多 RAM，2 个 CPU 或更多 CPU，硬盘 30GB 或更多
集群中所有机器之间网络互通
可以访问外网，需要拉取镜像，如果服务器不能上网，需要提前下载镜像并导入节点
禁止 swap 分区

2、准备环境

角色	IP	组件
m1(主节点)	192.168.174.141	kube-apiserver，kube-controller-manager，kube-scheduler，etcd
n1(工作节点)	192.168.174.141	kubelet，kube-proxy，docker etcd

3、操作系统初始化配

修改主机名

m1节点
```
hostnamectl set-hostname m1
```
n1节点
```
hostnamectl set-hostname n1
```

以下操作m1、n1相同

关闭防火墙

systemctl stop firewalld
systemctl disable firewalld

关闭selinux

setenforce 0 # 临时关闭
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config # 永久关闭

关闭swap

swapoff -a # 临时关闭；关闭swap主要是为了性能考虑
sed -ri 's/.*swap.*/#&/' /etc/fstab
free # 可以通过这个命令查看swap是否关闭了

在这里插入图片描述

时间与windows同步

yum install ntpdate -y
ntpdate time.windows.com

将桥接的IPv4流量传递到iptables的链

cat > /etc/sysctl.d/k8s.conf << EOF
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF

sysctl --system

添加主机名与IP对应的关系

vim /etc/hosts

192.168.174.141 m1
192.168.174.142 n1

4、部署etcd集群，m1、n1节点都需要部署

准备 cfssl 证书生成工具 ( master上操作 )

cfssl 是一个开源的证书管理工具，使用 json 文件生成证书，相比 openssl 更方便使用。找任意一台服务器操作，这里用 Master 节点(wget速度太慢的话建议在windows用科学上网工具下载后传到centos，传过去的问题件一般没有w权限，需要添加权限)

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

创建工作目录

mkdir -p ~/TLS/{etcd,k8s}
cd ~/TLS/etcd

自签 CA

cat > ca-config.json << EOF
{
  "signing": {
    "default": {
      "expiry": "87600h"
    },
    "profiles": {
      "www": {
         "expiry": "87600h",
         "usages": [
            "signing",
            "key encipherment",
            "server auth",
            "client auth"
        ]
      }
    }
  }
}
EOF

cat > ca-csr.json << EOF
{
    "CN": "etcd CA",
    "key": {
        "algo": "rsa",
        "size": 2048
    },
    "names": [
        {
            "C": "CN",
            "L": "Beijing",
            "ST": "Beijing"
        }
    ]
}
EOF

生成证书

cfssl gencert -initca ca-csr.json | cfssljson -bare ca -
ls *pem

使用自签 CA 签发 Etcd HTTPS 证书创建证书申请文件：(修改对应的master和node的IP地址)

cat > server-csr.json << EOF
{
    "CN": "etcd",
    "hosts": [
    "192.168.174.141",
    "192.168.174.142"
    ],
    "key": {
        "algo": "rsa",
        "size": 2048
    },
    "names": [
        {
            "C": "CN",
            "L": "BeiJing",
            "ST": "BeiJing"
        }
    ]
}
EOF

生成证书

cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=www server-csr.json | cfssljson -bare server
ls server*pem

从 Github 下载二进制文件下载地址上传到centos(科学上网工具)
```
https://github.com/etcd-io/etcd/releases
```

创建工作目录并解压二进制包

mkdir /opt/etcd/{bin,cfg,ssl} -p
tar zxvf etcd-v3.4.18-linux-amd64.tar.gz
mv etcd-v3.4.18-linux-amd64/{etcd,etcdctl} /opt/etcd/bin/
cp /opt/etcd/bin/etcdctl /usr/bin

创建etcd.conf （修改对应的master的ip地址）

cat > /opt/etcd/cfg/etcd.conf << EOF
ETCD_OPTS="--name=etcd-1 \\
--data-dir=/var/lib/etcd/default.etcd \\
--listen-peer-urls=https://192.168.174.141:2380 \\

部署kube-proxy完成====

8、部署CNI网络

先准备好 CNI 二进制文件，下载地址：https://github.com/containernetworking/plugins/releases/download/v0.8.6/cni-plugins-linux-amd64-v0.8.6.tgz
上传到centos，解压二进制包并移动到默认工作目录(Worker节点操作)
```
mkdir /opt/cni/bin
tar zxvf cni-plugins-linux-amd64-v0.8.6.tgz -C /opt/cni/bin
```
部署 CNI 网络(Master节点操作)

```
kubectl apply -f kube-flannel.yml
```

部署nginx测试(Master节点操作)

kubectl create deployment nginx --image=nginx
kubectl expose deployment nginx --port=80 --type-NodePort
kubectl get pods,svc

在这里插入图片描述

通过worker节点的ip地址:33210可以访问说明集群搭建成功
