minio对象存储

Minio安装 01、概述

中文官网：http://www.minio.org.cn/

英文官网：https://min.io/

02、Minio是什么？

MinIO 服务器, MinIO 客户端, SDKs 等各种资源下载
遵循Apache license version 2.0开源

构建高性能的云原生数据
机器学习，大数据分析，海量存储的基础架构
MinIO支持各种应用程序数据工作负载
在中国：阿里巴巴、腾讯、百度、中国联通、华为、中国移动等等9000多家企业也都在使用MinIO产品

阿里云OSS ：上传文件免费，使用收费
自己搭建：Fastdfs但是成本和配置非常负载
Minio ：有OSS存储能力，同时非常漂亮后台管理。安装非常方便，集群非常方便，使用起来和阿里oss存储几乎一模一样。

03、下载安装

参考：http://www.minio.org.cn/download.shtml#/windows

准备工作

准备虚拟机或者云服务器
使用finalshell / xshell 进行远程链接
注意：如果虚拟机最好在学习阶段把防火墙全部关闭
如果是阿里云服务：请注意把对应的端口9100和9000请注意在【安全组】开放。

04、安装MinIO

官网地址：https://docs.min.io

默认安装centos安装如下

mkdir -p /usr/local/minio
cd /usr/local/minio
wget https://dl.min.io/server/minio/release/linux-amd64/minio
chmod +x minio
./minio server /data

默认访问地址是：http://ip:9000/ 默认账号密码是：minioadmin / minioadmin

2、使用修改账号和密码进行安装（使用这个）

mkdir -p /usr/local/minio
cd /usr/local/minio
wget https://dl.min.io/server/minio/release/linux-amd64/minio
chmod +x minio

export MINIO_ROOT_USER=root
export MINIO_ROOT_PASSWORD=12345678
./minio server --console-address 0.0.0.0:9100 /usr/local/minio/data >/usr/local/minio/minio.log 2>&1 &

可以编写sh脚本

新建一个：start.sh

export MINIO_ROOT_USER=root
export MINIO_ROOT_PASSWORD=12345678
./minio server --console-address 0.0.0.0:9100 /usr/local/minio/data >/usr/local/minio/minio.log 2>&1 &

chmod +x start.sh

./start.sh

5、让后访问即可

http://ip:9100/

6、如果你在云服务器，就必须在阿里云的对应ip的安全组中把，9100和9000进行开放即可。

7、创建存储桶Bucket

05、java对接minio

1：依赖


    io.minio
    minio
    8.3.7

2：定义文件上传类：

2-1、构建一个springboot工程

2-2、配置

application.yml配置如下：

spring:
  servlet:
    multipart:
      # 文件上传大小限制。超过该值直接报错
      max-file-size: 20MB
      # 文件最大请求限制，用于批量上传
      max-request-size: 20MB

# MinIO 配置
minio:
  endpoint: http://139.224.164.101:9000      # MinIO服务地址
  fileHost: http://139.224.164.101:9000      # 文件地址host
  bucketName: pugapp                      # 存储桶bucket名称
  accessKey: root                         # 用户名
  secretKey: 12345678                     # 密码
  imgSize: 20                           # 图片大小限制，单位：m
  fileSize: 20                          # 文件大小限制，单位：m

2-2、定义一个配置类

package com.pug.config.minio;

import lombok.Data;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
@Data
public class MinIOConfig {

    @Value("${minio.endpoint}")
    private String endpoint;
    @Value("${minio.fileHost}")
    private String fileHost;
    @Value("${minio.bucketName}")
    private String bucketName;
    @Value("${minio.accessKey}")
    private String accessKey;
    @Value("${minio.secretKey}")
    private String secretKey;

    @Value("${minio.imgSize}")
    private Integer imgSize;
    @Value("${minio.fileSize}")
    private Integer fileSize;

    @Bean
    public MinIoUploadService creatMinioClient() {
        return new MinIoUploadService(endpoint, bucketName, accessKey, secretKey, imgSize, fileSize);
    }
}

2-3、编写一个文件上传的类

package com.pug.config.minio;

    }
