shell命令

简介

Minio是Apache License v2.0下发布的对象存储服务器。它与Amazon S3云存储服务兼容。它最适合存储非结构化数据，如照片，视频，日志文件，备份和容器/ VM映像。对象的大小可以从几KB到最大5TBMinio服务器足够轻，可以与应用程序堆栈捆绑在一起，类似于NodeJS，Redis和MySQL。https://docs.minio.io/

使用分布式文件服务FASTDFS和阿里云的OSS对象存储来存文件。奈何OSS太贵，FASTDFS搭建配置又太繁琐，推荐高性能对象存储服务MinIO。

Docker安装

docker pull minio/minio

docker run -p 9000:9000 --name minio \
  -e "MINIO_ACCESS_KEY=minio" \
  -e "MINIO_SECRET_KEY=gulimall_minio" \
  -v /mydata/minio/data:/data \
  -v /mydata/minio/config:/root/.minio \
  -d minio/minio server /data

存储桶命名规则

以下规则适用于命名 S3 存储桶：

存储桶名称必须长在 3 到 63 个字符之间。
存储桶名称只能由小写字母、数字、点（.）和连字符（-）组成。
存储桶名称必须以字母或数字开头和结尾。
存储桶名称不得格式化为 IP 地址（例如，192.168.5.4）。
存储桶名称在分区中必须是唯一的。分区是区域的分组。AWS 目前有三个分区：（标准区域）、（中国区域）和（AWS GovCloud [美国]区域）。awsaws-cnaws-us-gov
与 Amazon S3 传输加速一起使用的存储桶的名称中不能有点（.）。有关传输加速的详细信息，请参阅亚马逊S3 传输加速。

java客户端使用

依赖：

<dependency>
    <groupId>io.minio</groupId>
    <artifactId>minio</artifactId>
    <version>7.0.2</version>
</dependency>

application.yml配置


# 图片服务器 minio配置
minio:
  ip: xxxxxxx:9000
  # minio登录账号密码
  accessKey: xxxxxxx
  secretKey: xxxxxxxx
 
  ## 桶名（文件夹）命名规则要符合 亚马逊S3标准 详情可看http://docs.aws.amazon.com/AmazonS3/latest/dev/BucketRestrictions.html
  bucketName:
    ## 照片文件夹
    facility: facility-photos

    }

读写策略json如下【简单粗暴点也可在搭建完成后直接在控制台操作】：

    "Statement": [{
        "Effect": "Allow",
