MINIO安装和使用
安装MINIO
docker pull minio/minio
mkdir /home/minio/data -p
cd /home/minio
docker run --name minio -p 9000:9000 -p 9090:9090 -d --restart=always -e "MINIO_ROOT_USER=imooc" -e "MINIO_ROOT_PASSWORD=imooc123456" -v /home/minio/data:/data minio/minio server /data --console-address ":9090" -address ":9000"
通过访问：192.168.233.128:9090 可以访问minio客户端
