linux minio单机安装

参考官方教程：

wget https://dl.min.io/server/minio/release/linux-amd64/minio
chmod +x minio
MINIO_ROOT_USER=minioadmin MINIO_ROOT_PASSWORD=minioadmin ./minio server /mnt/minio/data --console-address ":9001"

执行上方命令后，用浏览器访问本地9001端口即可看到控制台界面，用默认用户名密码登录即可，文件存储目录是上面指定的/mnt/minio/data目录
登录之后，可以在界面上创建自己的Bucket,生成accesskey,新建用户等
比如：可以新建test用户密码为test12345678A，配置好readwrite和diagnostics策略,新建testbucket桶，Access Policy设置为public。
minio默认的访问端口是9000，在界面上上传一张图片：2022-01-22_18-40.png
那么用本机ip端口9000就可以访问这个图片：
比如：http://127.0.0.1:9000/testbucket/2022-01-22_18-40.png

windows minio单机安装

参考官方教程：

PS> Invoke-WebRequest -Uri "https://dl.min.io/server/minio/release/windows-amd64/minio.exe" -OutFile "C:\minio.exe"
PS> setx MINIO_ROOT_USER admin
PS> setx MINIO_ROOT_PASSWORD password
PS> C:\minio.exe server F:\Data --console-address ":9001"
