Minio设置永久下载链接一、问题描述

minio分享文件的链接，最多支持分享七天，而需求要求设置永久可下载？二、解决过程

minio提供了一个客户端工具。可以直接对minio server进行配置，将指定桶设置为公共永久可下载。1.安装客户端 首先是安装minio客户端，这个官方文档很清楚，各取所需吧.(Linux 或者windows 选择下载一个即可)2.设置自定义命令并启动Linux下： alias mc="./mc"windows下： 至此，我们的minio client就安装完成了。3. 添加服务端host 使用 minio client 将我自己的 minio server 添加到 mc 的配置管理： accessKey：admin

secretKey: password 这样我们才能直接管理这个 minio server 端。4. 配置下载策略 配置策略命令查看: mc policymc policy set download minio/mybucketmc policy set public minio/mybucketmc policy set public minio/mybucket

这个命令的作用是将 server 端的 mybucket 桶设置为开放管理，可以直接通过 url 进行下载。[桶名]/[路径]可以一直拼接到具体的文件夹或文件

PS: python 代码形式设置永久可下载环境： python3安装包：pip install minio# 1.建立连接from minio import MiniominioClient = Minio(endpoint='', # 文件服务地址access_key='admin', # 用户名secret_key='etImnEJYl', # 密钥secure=False # 设为True代表启用HTTPS)# 2.设置永久可下载#a. 桶名bucket_name = 'test_file' # 修改为自己已创建的桶名#b.通过桶权限设置方法，修改时间期限限制。policy = '{"Version":"2012-10-17","Statement":[{"Effect":"Allow","Principal":{"AWS":

["*"]},"Action":["s3:GetBucketLocation","s3:ListBucket"],"Resource": ["arn:aws:s3:::%s"]},{"Effect":"Allow","Principal":{"AWS":["*"]},"Action":

["s3:GetObject"],"Resource":["arn:aws:s3:::%s/*"]}]}' % (bucket_name, bucket_name)_bucket_policy(bucket_name=bucket_name, policy=policy)

四、命令示例[root@hoolink-hz-192-168-1-153 mc]# mc policy list minio/test-hoolink-edmAccess permission for `minio/test-hoolink-edm` is set to `public`[root@hoolink-hz-192-168-1-153 mc]# mc policy list minio/test-hoolink-edmtest-hoolink-edm/* => readwrite[root@hoolink-hz-192-168-1-153 mc]#

Access permission for `minio/test-hoolink-edm-preview` is set to `public`[root@hoolink-hz-192-168-1-153 mc]#

[root@hoolink-hz-192-168-1-153 mc]#
