MINIO_ROOT_USER="minio"
MINIO_ROOT_PASSWORD="minio@123"
MINIO_VOLUMES=" /usr/local/minio/data"
MINIO_OPTS="--address 0.0.0.0:9000"
MINIO_OPTS1="--console-address 0.0.0.0:19001"
编辑配置文件文件
vim /etc/systemd/system/minio.service
添加配置文件内容 (主意启动器路径,自定义服务配置文件路径,以及连接端口要与配置文件里的对应)

当文件上传之后比如一张图片,直接通过图片路径访问报一下错误
这是因为浏览器打开没有权限
解决办法,默认显示的是n/a,设置minio代理权限,选择对应的桶,将其代理权限也设置为公有
就可以成功访问了
