1、下载链接
wget http://dl.minio.org.cn/server/minio/release/darwin-amd64/minio
2、赋予可执行权限,文件颜色变绿了表示可执行,之前是白色
chmod +x minio
3、启动
./minio server /data
#后台运行
nohup ./minio server ./data > ./logs/minio.log —address 0.0.0.0:9000 —console-address 0.0.0.0:9001 2>&1 &#

用户名
export MINIO_ACCESS_KEY=minio2021
#密码
export MINIO_SECRET_KEY=minio2021
查看进程
