对象存储-Minio到底有多强?

·  阅读 423

简介:

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。

特点:

  • 高性能
  • 可扩展性
  • 云的原生支持
  • 简单
  • 开放全部源代码 + 企业级支持
  • 与Amazon S3 兼容

一、搭建

支持Docker镜像部署

1、从hub.docker.com拉取最新镜像

命令:docker pull minio/minio (此命令就等同于 : docker pull minio/minio:latest)

2、 创建目录

一个用来存放配置,一个用来存储上传文件的目录

启动前需要先创建Minio外部挂载的配置文件( /home/minio/config),和存储上传文件的目录( /home/minio/data)

mkdir -p /home/minio/config
mkdir -p /home/minio/data
复制代码

3、创建Minio容器并运行

多行命令

docker run -p 9000:9000 -p 9090:9090 \
     --net=host \
     --name minio \
     -d --restart=always \
     -e "MINIO_ACCESS_KEY=minioadmin" \
     -e "MINIO_SECRET_KEY=minioadmin" \
     -v /home/minio/data:/data \
     -v /home/minio/config:/root/.minio \
     minio/minio server \
     /data --console-address ":9090" -address ":9000"
复制代码

单行命令

docker run -p 9000:9000 -p 9090:9090      --net=host      --name minio      -d --restart=always      -e "MINIO_ACCESS_KEY=minioadmin"      -e "MINIO_SECRET_KEY=minioadmin"      -v /home/minio/data:/data      -v /home/minio/config:/root/.minio      minio/minio server      /data --console-address ":9090" -address ":9000"
复制代码

9090:客户端端口

9000:api端口(项目中所用)

MINIO_ACCESS_KEY :账号

MINIO_SECRET_KEY :密码(账号长度必须大于等于5,密码长度必须大于等于8位)

4、客户端访问

地址:http://ip:9090

二、整合项目(SpringBoot项目)

1、application.yml

2、minio文件上传工具类

public class MinioUtil {
    private static String minioUrl;
    private static String minioName;
    private static String minioPass;
    private static String bucketName;

    public static void setMinioUrl(String minioUrl) {
        MinioUtil.minioUrl = minioUrl;
    }

    public static void setMinioName(String minioName) {
        MinioUtil.minioName = minioName;
    }

    public static void setMinioPass(String minioPass) {
        MinioUtil.minioPass = minioPass;
    }

    public static void setBucketName(String bucketName) {
        MinioUtil.bucketName = bucketName;
    }

    public static String getMinioUrl() {
        return minioUrl;
    }

    public static String getBucketName() {
        return bucketName;
    }

    private static MinioClient minioClient = null;

3、controller

@PostMapping(value = "/uploadMinio")
    public Result<?> uploadMinio(HttpServletRequest request) {
        Result<?> result = new Result<>();
        String bizPath = request.getParameter("biz");
        if(oConvertUtils.isEmpty(bizPath)){
            bizPath = "";
        }
        MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
        MultipartFile file = multipartRequest.getFile("file");// 获取上传文件对象
        String orgName = file.getOriginalFilename();// 获取文件名
        orgName = CommonUtils.getFileName(orgName);
        String file_url =  MinioUtil.upload(file,bizPath);
        if(oConvertUtils.isEmpty(file_url)){
            return Result.error("上传失败,请检查配置信息是否正确!");
        }
        //保存文件信息
        OSSFile minioFile = new OSSFile();
        minioFile.setFileName(orgName);
        minioFile.setUrl(file_url);
        ossFileService.save(minioFile);
        result.setMessage(file_url);
        result.setSuccess(true);
        return result;
    }

4、前端组件

<a-upload
        name="file"
        :multiple="false"
        :action="minioUploadAction"
        :headers="tokenHeader"
        :showUploadList="false"
        :beforeUpload="beforeUpload"
        @change="handleChange">
        <a-button>
          <a-icon type="upload"/>
          MINIO文件上传
        </a-button>
</a-upload>
复制代码
