 minio权限添加

minio权限添加https://blog.csdn.net/xnian_/article/details/130841657

windows环境部署

1. 安装最小IO服务器

   从以下 URL 下载 MinIO 可执行文件：cmd 复制下面的下载

   https://dl.min.io/server/minio/release/windows-amd64/minio.exe

   下一步包括运行可执行文件的说明。 不能从资源管理器或通过双击文件来运行可执行文件。 相反，您调用可执行文件来启动服务器。

2. 启动

   在 PowerShell 或命令提示符下，导航到可执行文件的位置或将文件的路径添加到系统。minio.exe$PATH

   使用此命令在文件夹中启动本地 MinIO 实例。 您可以替换为本地计算机上的另一个驱动器或文件夹路径。d:\minio d:\minio （自己下载的目录）

   .\minio.exe server d:\minio --console-address :9090

   该过程将其输出打印到系统控制台，类似于以下内容：

3. 这个页面不能关闭，关闭后客户端无法访问，http://127.0.0.1:9000

                 初始的登录账号：

                RootUser: minioadmin
                RootPass: minioadmin

API: http://192.0.2.10:9000  http://127.0.0.1:9000

RootPass: minioadmin

Console: http://192.0.2.10:9090 http://127.0.0.1:9090
RootUser: minioadmin
RootPass: minioadmin

Command-line: https://min.io/docs/minio/linux/reference/minio-mc.html
   $ mc alias set myminio http://192.0.2.10:9000 minioadmin minioadmin

Documentation: https://min.io/docs/minio/linux/index.html

WARNING: Detected default credentials 'minioadmin:minioadmin', we recommend tha

linux部署

创建自己的minio目录

mkdir minio

1远程拉取：

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

安装minio

2 文件赋权

给minio二进制文件赋权限，否则无法执行：

chmod +x minio

3启动minio

MINIO_ACCESS_KEY=minioadmin MINIO_SECRET_KEY=minioadmin nohup ./minio server --console-address ":9000" --address ":9001"  /data/ > /minio.log 2>&1 &

或

./minio server --console-address ":9000" --address ":9001"  /data/ > ./minio.log 2>&1 &

浏览器访问服务器minio,地址ip:9000,默认账号minioadmin 密码minioadmin

需要关闭防火墙linux防火墙操作命令https://blog.csdn.net/xnian_/article/details/130847602

可以直接将保存图片的地址返回前端，通过地址直接支持查看图片，不需要调用后台代码
