大家好，我是一安，今天介绍一个高性能对象存储MinIo
之前公司使用的是FastDFS，一个开源的轻量级分布式文件系统，为互联网应用量身定做，简单、灵活、高效，采用C语言开发，由阿里巴巴开发并开源
FastDFS对文件进行管理，功能包括：文件存储、文件同步、文件访问（文件上传、文件下载、文件删除）等，解决了大容量文件存储的问题，特别适合以文件为载体的在线服务，如相册网站、文档网站、图片网站、视频网站等等。
FastDFS充分考虑了冗余备份、线性扩容等机制，并注重高可用、高性能等指标，使用FastDFS很容易搭建一套高性能的文件服务器集群提供文件上传、下载等服务
但由于上电信云，电信云提供的ctg-slb（也就是nginx）不支持编译安装fastdfs-nginx-module，所以考虑使用MinIo代替FastDFS
MinIO是根据GNU Affero通用公共许可证v3.0发布的高性能对象存储。它与Amazon S3云存储服务兼容。使用MinIO构建用于机器学习，分析和应用程序数据工作负载的高性能基础架构
MinIo安装
本文采用docker方式安装测试
docker run -p 9000:9000 -p 9001:9001 --name minio -d -e "MINIO_ACCESS_KEY=admin12345" -e "MINIO_SECRET_KEY=admin12345" -v /mydata/minio/data:/data -v /mydata/minio/config:/root/.minio minio/minio server /data --console-address ":9000" --address ":9001"
命令解释如下：
-p：9000是图形界面的端口，9001是API的端口，在使用SDK连接需要用到
MINIO_ACCESS_KEY：指定图形界面的用户名
MINIO_SECRET_KEY：指定图形界面的密码
1.登录界面：
2.登录成功：3.创建一个测试桶4.创建accessKey和secretKey以上搭建的都是单机版的，想要了解分布式 的方式请查看官网文档：https://www.minio.org.cn/

servlet:
multipart:
max-file-size: -1
server:
port: 8011
minio:

image-size: 10485760 # 我在这里设定了 图片文件的最大大小

总结
MInIO虽然是个开源项目，但是功能非常强大，小型项目中完全可以用它实现对象存储，也可以使用MinIO搭建一个免费的图床
