Harbor多实例高可用共享存储搭建

多实例共享存储架构图

本文 LB 不使用 Nginx，使用阿里SLB。

更多 Harbor 架构，请参考 聊聊Harbor架构

本文架构需要考虑三个问题

• 1、共享存储的选取，Harbor的后端存储目前支持AWS S3、Openstack Swift, Ceph等。本文使用阿里云极速性NAS，磁盘IO性能比单块磁盘读写性能要好。使用 NFS V3 版本挂载。
• 2、Session 不能在不同的实例上共享，所以Harbor Redis 需要单独部署，并且多个实例连接相同的Redis。
• 3、Harbor多实例数据库问题，必须单独部署一个数据库，并且多个实例连接相同的数据库。

注意：生产环境如果使用阿里云NAS，推荐使用 极速性NAS，不推荐使用 通用型NAS。

阿里云NAS性能参考文档 https://help.aliyun.com/document_detail/124577.html?spm=a2c4g.11186623.6.552.2eb05ea0HJUgUB

主机名 IP地址 系统 harbor1 192.168.10.10 centos7.9 harbor2 192.168.10.11 centos7.9

Harbor 选择在线部署，使用 docker-compose 部署，docker-compose 和 Docker 部署环境本文不在介绍，网上可以搜索到相关文档。

1、挂载阿里云极速性NAS

harbor1 和 harbor2 机器都需要执行挂载 NAS

配置开机自动挂载，打开 /etc/fstab 配置文件，添加挂载命令。

# 创建 NAS 挂载目录
$ mkdir /data

# 提高同时发起的NFS请求数量
$ sudo echo "options sunrpc tcp_slot_table_entries=128" >>  /etc/modprobe.d/sunrpc.conf 
$ sudo echo "options sunrpc tcp_max_slot_table_entries=128" >>  /etc/modprobe.d/sunrpc.conf

• 挂载NFS v4文件系统，添加以下命令：

file-system-id.region.nas.aliyuncs.com:/ /data nfs vers=4,minorversion=0,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,_netdev,noresvport 0 0

• 如果您要挂载NFS v3文件系统，添加以下命令：

file-system-id.region.nas.aliyuncs.com:/ /data nfs vers=3,nolock,proto=tcp,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,_netdev,noresvport 0 0

# 在 /etc/fstab 配置文件添加好挂载，并执行挂载
$ mount -a

# 检查挂载，如果结果中存在NFS文件系统的挂载地址，则说明挂载成功
$ df -h | grep aliyun

2、临时部署单机 Harbor

在 harbor1 机器上操作

# 在线部署Harbor
$ cd /opt/
$ wget https://github.com/goharbor/harbor/releases/download/v2.2.1/harbor-online-installer-v2.2.1.tgz
$ tar xf harbor-online-installer-v2.2.1.tgz
$ cd /opt/harbor
$ cp harbor.yml.tmpl harbor.yml

# 创建harbor数据存储
$ mkdir /data/harbor

# 添加域名证书，已有域名SSL证书
$ mkdir /data/harbor/cert

# 把SSL证书公钥和私钥上传到 /data/harbor/cert 目录中
$ scp harbor.example.pem [email protected]:/data/harbor/cert/
$ scp harbor.example.key [email protected]:/data/harbor/cert/

# 配置 harbor.yml 文件，下面是修改后文件与原文件比较结果
$ diff harbor.yml harbor.yml.tmpl

< hostname: harbor.example.com
---
> hostname: reg.mydomain.com
17,18c17,18
<   certificate: /data/harbor/cert/harbor.example.pem
<   private_key: /data/harbor/cert/harbor.example.key
---
>   certificate: /your/certificate/path
>   private_key: /your/private/key/path
29c29
< external_url: https://harbor.example.com
---
> # external_url: https://reg.mydomain.com:8433

< data_volume: /data/harbor
---
> data_volume: /data

# 生成配置文件
$ cd /opt/harbor

# harbor开启helm charts 和 镜像漏洞扫描
$ ./prepare --with-notary --with-trivy --with-chartmuseum

# 安装
$ ./install.sh --with-notary --with-trivy --with-chartmuseum

# 查看
$ docker-compose ps

3、单独部署Harbor数据库和Redis

# 创建 postgres 和 redis 存储目录
$ mkdir -p /data/harbor-redis /data/harbor-postgresql

# 修改所属组
$ chown -R 999.999 /data/harbor-redis /data/harbor-postgresql

# 创建 postgres 和 redis docker-compose.yml 文件
$ vim docker-compose.yml

version: '2.3'

services:
  redis:
    image: goharbor/redis-photon:v2.2.1
    container_name: harbor-redis
    restart: always
    cap_drop:
      - ALL
    cap_add:
      - CHOWN
      - SETGID
      - SETUID
    volumes:
      - /data/harbor-redis:/var/lib/redis
    networks:
      - harbor-db
    ports:
      - 6379:6379
  postgresql:
    image: goharbor/harbor-db:v2.2.1
    container_name: harbor-postgresql
    restart: always
    cap_drop:
      - ALL
    cap_add:
      - CHOWN
      - DAC_OVERRIDE
      - SETGID
      - SETUID
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: test2021
    volumes:
      - /data/harbor-postgresql:/var/lib/postgresql/data:z
    networks:
      - harbor-db
    ports:
      - 5432:5432

networks:
 harbor-db:
   driver: bridge

# 部署 postgres 和 redis
$ docker-compose up -d

4、导入 postgres 数据

# 进入临时harbor-db容器导出相关表及数据
$ docker exec -it -u postgres harbor-db bash

# 导出数据
$ pg_dump -U postgres registry > /tmp/registry.sql 
$ pg_dump -U postgres notarysigner > /tmp/notarysigner.sql  
$ pg_dump -U postgres notaryserver > /tmp/notaryserver.sql

# 将数据导入单独部署的PostgreSQL数据库
$ psql -h 192.168.10.10 -U postgres registry -W < /tmp/registry.sql
$ psql -h 192.168.10.10 -U postgres notarysigner -W < /tmp/notarysigner.sql
$ psql -h 192.168.10.10 -U postgres notaryserver -W < /tmp/notaryserver.sql

5、清理临时部署单机Harbor数据和相关配置文件

# 清理harbr数据和配置文件
$ cp -a /data/harbor/cert /tmp/
$ rm -rf /data/harbor/*
$ rm -rf /opt/harbor
$ cp -a /tmp/cert /data/harbor/

# 重新创建配置文件
$ cd /opt/
$ tar xf harbor-online-installer-v2.2.1.tgz
$ cd /opt/harbor

# 修改配置文件，连接单独部署postgres和redis，注释harbor自带的postgres和redis
$ cp harbor.yml.tmpl harbor.yml
$ diff harbor.yml harbor.yml.tmpl

6、配置阿里云SLB

不具体介绍SLB配置方法，具体配置方法参考下面阿里云SLB配置文档，配置 443端口，使用 TCP 协议，后端映射到两台 harbor1 和 harbor2 443端口上。

SLB配置方法请参考阿里云文档 https://help.aliyun.com/document_detail/205495.html?spm=a2c4g.11174283.6.666.f9aa1192jngFKC
