docker-compose部署MinIO分布式集群



概述

MinIO是全球领先的对象存储先锋,目前在全世界有数百万的用户。


  • 高性能

    ,在标准硬件上,读/写速度上高达183GB/秒和171GB/秒,拥有更高的吞吐量和更低的延迟

  • 可扩展性

    ,为对象存储带来了简单的缩放模型,通过添加更多集群可以扩展空间

  • 简单

    ,极简主义是MinIO的指导性设计原则,即可在几分钟内安装和配置

  • 与Amazon S3兼容

    ,亚马逊云的

    S3 API

    (接口协议)是在全球范围内达到共识的对象存储的协议,是全世界内大家都认可的标准

  • 数据安全

    ,使用纠删码来保护数据免受硬件故障和无声数据损坏



纠删码


纠删码

是一种恢复丢失和损坏数据的数学算法, Minio默认采用

Reed-Solomon code

将数据拆分成N/2个数据块和N/2个奇偶校验块。这就意味着如果是16块盘,一个对象会被分成8个数据块、8个奇偶校验块,你可以丢失任意8块盘(不管其是存放的数据块还是校验块),你仍可以从剩下的盘中的数据进行恢复。



部署

官方推荐

docker-compose.yaml

稍加修改,内容如下:

version: '3.7'

# 所有容器通用的设置和配置
x-minio-common: &minio-common
  image: minio/minio
  command: server --console-address ":9001" http://minio{1...4}/data
  expose:
    - "9000"
  # environment:
    # MINIO_ROOT_USER: minioadmin
    # MINIO_ROOT_PASSWORD: minioadmin
  healthcheck:
    test: ["CMD", "curl", "-f", "http://localhost:9000/minio/health/live"]
    interval: 30s
    timeout: 20s
    retries: 3

# 启动4个docker容器运行minio服务器实例
# 使用nginx反向代理9000端口,负载均衡, 你可以通过9001、9002、9003、9004端口访问它们的web console
services:
  minio1:
    <<: *minio-common
    hostname: minio1
    ports:
      - "9001:9001"
    volumes:
      - ./data/data1:/data

  minio2:
    <<: *minio-common
    hostname: minio2
    ports:
      - "9002:9001"
    volumes:
      - ./data/data2:/data

  minio3:
    <<: *minio-common
    hostname: minio3
    ports:
      - "9003:9001"
    volumes:
      - ./data/data3:/data

  minio4:
    <<: *minio-common
    hostname: minio4
    ports:
      - "9004:9001"
    volumes:
      - ./data/data4:/data

  nginx:
    image: nginx:1.19.2-alpine
    hostname: nginx
    volumes:
      - ./config/nginx.conf:/etc/nginx/nginx.conf:ro
    ports:
      - "9000:9000"
    depends_on:
      - minio1
      - minio2
      - minio3
      - minio4

接着新建文件夹

config

,新建配置

nginx.conf

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  4096;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;
    sendfile        on;
    keepalive_timeout  65;

    # include /etc/nginx/conf.d/*.conf;

    upstream minio {
        server minio1:9000;
        server minio2:9000;
        server minio3:9000;
        server minio4:9000;
    }

    server {
        listen       9000;
        listen  [::]:9000;
        server_name  localhost;

        # To allow special characters in headers
        ignore_invalid_headers off;
        # Allow any size file to be uploaded.
        # Set to a value such as 1000m; to restrict file size to a specific value
        client_max_body_size 0;
        # To disable buffering
        proxy_buffering off;

        location / {
            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;

            proxy_connect_timeout 300;
            # Default is HTTP/1, keepalive is only enabled in HTTP/1.1
            proxy_http_version 1.1;
            proxy_set_header Connection "";
            chunked_transfer_encoding off;

            proxy_pass http://minio;
        }
    }

}

执行启动命令,看到各个节点

healthy

状态即成功

docker-compose up -d

启动成功



配置

浏览器访问任意节点

web console

,进行简单配置,配置会自动在节点间同步

创建桶(Buckets)后,选择管理(Manage),在总结(Summary)中可以进行访问策略(Access Policy)配置

访问策略

选择菜单设置(Settings)-配置( Configuration),选择扫描器(Scanner),配置

Max Wait



Cycle

为1s,可以大大加快节点间的同步效率

扫描器配置
