    Minio

    上传文件如果不使用云服务的话,需要本地搭建,一般选择 FastDFS 但是 FastDFS 安装比较复杂,今天了解一款安装使用更简单的存储系统 MinIO

    MinIO 是一款高性能、分布式的对象存储系统. 它是一款软件产品, 可以100%的运行在标准硬件。即X86等低成本机器也能够很好的运行MinIO。

    MinIO与传统的存储和其他的对象存储不同的是:它一开始就针对性能要求更高的私有云标准进行软件架构设计。因为MinIO一开始就只为对象存储而设计。所以他采用了更易用的方式进行设计,它能实现对象存储所需要的全部功能,在性能上也更加强劲,它不会为了更多的业务功能而妥协,失去MinIO的易用性、高效性。 这样的结果所带来的好处是:它能够更简单的实现局有弹性伸缩能力的原生对象存储服务。

    MinIO在传统对象存储用例(例如辅助存储,灾难恢复和归档)方面表现出色。同时,它在机器学习、大数据、私有云、混合云等方面的存储技术上也独树一帜。当然,也不排除数据分析、高性能应用负载、原生云的支持。

    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

    安装 Minio

    使用docker安装

    拉取镜像

    docker pull minio/minio
    

    启动

    docker run -p 9000:9000 -p 9001:9001 -d --name minio -v /opt/docker/minio/data:/data -v /opt/docker/minio/config:/root/.minio -e "MINIO_ROOT_USER=minio" -e "MINIO_ROOT_PASSWORD=minio@123456" minio/minio server /data --console-address ":9000" --address ":9001"
    

    使用9000端口 登录控制台

    创建存储桶

    设置桶权限

    创建 Java 客户端
