按照这个步骤来，宝贝保你一步到位
一、minio版本安装：这里我安装的新版本
新版本安装
# docker 下载镜像
docker pull minio/minio
# 安装镜像
docker run \
--name minio \
-p 9000:9000 \
-p 9090:9090 \
-d --restart=always \
-e "MINIO_ROOT_USER=minio" \
-e "MINIO_ROOT_PASSWORD=minio123" \
-v /opt/docker_minio/data:/data \
-v /opt/docker_minio/config:/root/.minio \
minio/minio server /data --console-address ":9090" --address ":9000"
# 查看日志
docker logs minio
# 注意注意注意
# console-address ":9090" 是页面控制台的端口号，而--address ":9000" 是我们代码中要写的端口号(详见下面application.properties配置)
# 页面地址 http://192.168.159.173:9090/login
老版本安装
# docker 下载镜像
docker pull minio/minio:RELEASE.2021-06-14T01-29-23Z
# 安装Minio
