SpringBoot集成Minio

现在流行的文件服务器基本上有minio,fastdfs,那么今天就说一下minio的安装及集成

安装部署minio

// 首先进入到你的目录

cd /ext/minio

wget https://dl.minio.io/server/minio/release/linux-amd64/minio

//给予可执行

chmod +x minio

//启动

minio server /ext/data

//或

minio server --config-dir=/ext/minio --address=:9000 //ext/data

//安装基本上就这样，启动起来访问一下 http://xxx.xx.xx.xx:9000/minio。一般默认安装的默认用户名密码为：minioadmin/minioadmin

开始和SpringBoot集成
