minio官方文档
我选择的是docker部署
docker pull minio/minio
docker run \
-p 9000:9000 \
-p 9001:9001 \
--name minio1 \
-v ~/minio/data:/data \
-e "MINIO_ROOT_USER=username" \
-e "MINIO_ROOT_PASSWORD=password" \
-d \
quay.io/minio/minio server /data --console-address ":9001"
访问http://localhost:9001/
进入控制台界面 ( 如果是云服务器记得打开9001端口)
然后上传一个图片
设置访问规则:
添加只读属性,前缀为 “*”,这样就可以浏览器访问了
访问:http://服务器ip:9000/桶名/文件名
最开始用的8.3.7, 和我的jar包冲突了,又换成8.2.1
