Minio 文件服务器介绍
MinIO是为性能和s3 api而设计的，100%开源。MinIO是具有严格安全性的大型私有云环境的理想选择
要求并提供跨各种工作负载的关键任务可用性。

Minio 文件服务器搭建
推荐使用docker 部署minio
从docker 仓库中下载minio镜像
docker pull minio/minio
docker run -p 9000:9000 --name minio
-d --restart=always
-e “MINIO_ACCESS_KEY= XXXXXX”
-e “MINIO_SECRET_KEY=XXXXXXXXXX”
-v /home/data:/data
-v /home/config:/root/.minio
minio/minio server /data
-d --restart=always \ //docker 服务重启的之后 容器也会重新启动
-e “MINIO_ACCESS_KEY=admin” \ //环境变量
-v /home/data:/data \ //挂载文件路径
容器正常启动后可以使用 http://XXXXXXX:9000 访问minio 服务器
通过Web 端可以右下叫的 + 按钮可以添加存储桶，设定存储桶的访问权限。
可以往存储桶中上传文件，可以分享访问链接
客户端使用
docker仓库中下载minio 客户端镜像
docker pull minio/mc
启动容器
docker run -it --entrypoint=/bin/sh minio/mc
客户端的使用参照官网说明
https://docs.min.io/docs/minio-client-quickstart-guide.html
Spring boot 整合
maven 依赖包引入
io.minio
minio
7.1.0
#minio配置
minio:
endpoint: http://服务器地址:9000/
accessKey: XXXXX
secretKey: XXXXXXXX
bucketName: joy //存储桶名称

在判断存储桶是否存在的时候抛出以上异常，发生错误的原因是，HTTP访问文件服务器的时候，构建request 的时候需要设定Header 参数 requestBuilder.header(“x-amz-date”, date.format(Time.AMZ_DATE_FORMAT));这里时间格式问题导致的。
判断是否docker 中的时间格式有问题，于是进入minio 服务端容器中，通过date 命令查看发现时间是UTC
1.复制相应的时区文件，替换系统时区文件；
cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
有的容器基础镜像是有这个文件的，直接拷贝就可以，如果不能拷贝，则是因为创建镜像时依赖的基础镜像 运行的容器没有这两个文件，使用下面的办法
- 创建文件夹
mkdir -p /usr/share/zoneinfo/Asia
3.回到宿主机，复制宿主机里的文件到容器中
docker cp /usr/share/zoneinfo/Asia/Shanghai 容器ID或容器名:/usr/share/zoneinfo/Asia
- 进入容器
docker exec -it 容器Id或容器名 /bin/sh
执行命令 cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
- 验证date
结果还是遇到同样的问题。。。。。…。。。…。。.。…。。
