2.4 部署docker （hdss7-21.host.com，hdss7-22.host.com，hdss7-200.host.com上）

2.4.1 安装

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

2.4.2 配置docker

mkdir  /etc/docker
vi  /etc/docker/daemon.json
{
  "graph": "/data/docker",
  "storage-driver": "overlay2",
  "insecure-registries": ["registry.access.redhat.com","quay.io","harbor.od.com"],
  "registry-mirrors": ["https://q2gr04ke.mirror.aliyuncs.com"],
  "bip": "172.7.21.1/24",
  "exec-opts": ["native.cgroupdriver=systemd"],
  "live-restore": true
}

bip要根据宿主机ip变化

注意：hdss7-21.host.com bip 172.7.21.1/24

hdss7-22.host.com bip 172.7.22.1/24

hdss7-200.host.com bip 172.7.200.1/24

2.5.6 设置harbor开机启动

[root@hdss7-200 harbor]# vim /etc/rc.d/rc.local  # 增加以下内容
# start harbor
cd /opt/harbor
/usr/docker-compose stop
/usr/docker-compose start

2.5.7 配置harbor的dns内网解析（hdss7-11）

[root@hdss7-11 ~]# vi /var/named/od.com.zone
2021123102 ; serial
harbor             A    10.4.7.200
[root@hdss7-11 ~]# systemctl restart named
[root@hdss7-11 ~]# dig -t A harbor.od.com +short
10.4.7.200

2.5.8 安装NGINX并配置

[root@hdss7-200 harbor]# yum install nginx -y
[root@hdss7-200 harbor]# vi /etc/nginx/conf.d/harbor.od.com.conf
server {
    listen       80;
    server_name  harbor.od.com;

    client_max_body_size 1000m;

    location / {
        proxy_pass http://127.0.0.1:180;
    }
}
[root@hdss7-200 harbor]# nginx -t
[root@hdss7-200 harbor]# systemctl start nginx
[root@hdss7-200 harbor]# systemctl enable nginx

2.5.9 浏览器打开harbor.od.com并测试

1、浏览器输入：harbor.od.com 用户名：admin 密码：Harbor12345

[root@hdss7-200 harbor]# docker pull nginx:1.7.9
[root@hdss7-200 harbor]# docker images |grep 1.7.9
[root@hdss7-200 harbor]# docker tag 84581e99d807 harbor.od.com/public/nginx:v1.7.9

4、登录harbor并上传到仓库

[root@hdss7-200 harbor]# docker login harbor.od.com
[root@hdss7-200 harbor]# docker push harbor.od.com/public/nginx:v1.7.9

3 部署master节点

3.1 部署etcd集群(hdss7-12，hdss7-21，hdss7-22)

etcd 的leader选举机制，要求至少为3台或以上的奇数台。

3.1.1 签发etcd证书( hdss7-200)

● 创建ca的json配置: /opt/certs/ca-config.json

○ server 表示服务端连接客户端时携带的证书，用于客户端验证服务端身份

○ client 表示客户端连接服务端时携带的证书，用于服务端验证客户端身份

○ peer 表示相互之间连接时使用的证书，如etcd节点之间验证

[root@hdss7-200 ~]# vi /opt/certs/ca-config.json
{
    "signing": {
        "default": {
            "expiry": "175200h"
        },
        "profiles": {
            "server": {
                "expiry": "175200h",
                "usages": [
                    "signing",
                    "key encipherment",
                    "server auth"
                ]
            },
            "client": {
                "expiry": "175200h",
                "usages": [
                    "signing",
                    "key encipherment",
                    "client auth"
                ]
            },
            "peer": {
                "expiry": "175200h",
                "usages": [
                    "signing",
                    "key encipherment",
                    "server auth",
                    "client auth"
                ]
            }
        }
    }
}

● 创建etcd证书配置：/opt/certs/etcd-peer-csr.json

重点在hosts上，将所有可能的etcd服务器添加到host列表，不能使用网段，新增etcd服务器需要重新签发证书

[root@hdss7-200 ~]# vi /opt/certs/etcd-peer-csr.json
{
    "CN": "k8s-etcd",
    "hosts": [
        "10.4.7.11",
        "10.4.7.12",
        "10.4.7.21",
        "10.4.7.22"
    ],
    "key": {
        "algo": "rsa",
        "size": 2048
    },
    "names": [
        {
            "C": "CN",
            "ST": "beijing",
            "L": "beijing",
            "O": "od",
            "OU": "ops"
        }
    ]
}

● 签发证书与检查

[root@hdss7-200 ~]# cd /opt/certs/
[root@hdss7-200 certs]# cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=peer etcd-peer-csr.json |cfssl-json -bare etcd-peer

[root@hdss7-200 certs]# ll
etcd-peer.csr
etcd-peer-csr.json
etcd-peer-key.pem
etcd-peer.pem

3.1.2 安装etcd(hdss7-12，hdss7-21，hdss7-22)

创建etcd用户

[root@hdss7-12 ~]# useradd -s /sbin/nologin -M etcd

下载软件，解压，做软连接

[root@hdss7-12 src]# wget https://github.com/etcd-io/etcd/releases/download/v3.1.20/etcd-v3.1.20-linux-amd64.tar.gz
[root@hdss7-12 src]# tar xf etcd-v3.1.20-linux-amd64.tar.gz -C /opt/
[root@hdss7-12 src]# cd ..
[root@hdss7-12 opt]# mv etcd-v3.1.20-linux-amd64/ etcd-v3.1.20
[root@hdss7-12 opt]# ln -s /opt/etcd-v3.1.20/ /opt/etcd

创建目录，拷贝证书文件

[root@hdss7-12 opt]# mkdir -p /opt/etcd/certs /data/etcd /data/logs/etcd-server

拷贝生成的证书文件

[root@hdss7-12 certs]# scp hdss7-200:/opt/certs/ca.pem .
[root@hdss7-12 certs]# scp hdss7-200:/opt/certs/etcd-peer.pem .
[root@hdss7-12 certs]# scp hdss7-200:/opt/certs/etcd-peer-key.pem .

创建etcd服务启动脚本

[root@hdss7-12 ~]# vi /opt/etcd/etcd-server-startup.sh
#!/bin/sh
./etcd --name etcd-server-7-12 \
       --data-dir /data/etcd/etcd-server \
