一、安裝部署
1、下載安裝包：MinIO | 高性能，對Kubernetes友好的對象存儲
2、放到磁盤中，后面會以這個文件進行服務器安裝
3、磁盤新建一個目錄用於存放上傳文件，比如我創建的為：Data
4、運行控制台程序：切換到安裝包所在目錄（后面部分為存儲路徑）， 輸入命令：minio.exe server D:\\Data
5、打開瀏覽器，訪問：http://127.0.0.1:9000 用戶名和密碼默認為：minioadmin，主界面如下
二、注冊成window服務
1. 下載winsw，下載地址：https://github.com/winsw/winsw/releases
2. 將WinSW-net461.exe復制到自定義的目錄，並重命名為自己想命名的服務名稱minio-server.exe
3. 同目錄下創建minio-server.xml。特別注意，xml和exe必須同名
4. 配置minio-server.xml文件
5. 使用minio-server.exe install安裝服務
安裝服務命令：minio-server.exe install
啟動服務命令：minio-server.exe start
停止服務命令：minio-server.exe stop
移除服務命令：sc delete minio-server
xml配置文件如下：
<service>
<id>minio-server</id>
<name>minio-server</name>
<description>minio文件存儲服務器</description>
<!-- 可設置環境變量 -->
<env name="HOME" value="%BASE%"/>
<executable>%BASE%\minio.exe</executable>
<arguments>server "%BASE%\data"</arguments>
<!-- <logmode>rotate</logmode> -->
<logpath>%BASE%\logs</logpath>
<log mode="roll-by-size-time">
<sizeThreshold>10240</sizeThreshold>
<pattern>yyyyMMdd</pattern>
<autoRollAtTime>00:00:00</autoRollAtTime>
<zipOlderThanNumDays>5</zipOlderThanNumDays>
<zipDateFormat>yyyyMMdd</zipDateFormat>
</log>
</service>
三、C#文件上傳下載
public async void testupload() { try { MinioClient minio = new MinioClient("127.0.0.1:9000", "minioadmin", "minioadmin"); //桶名稱 string buckName = "202110001"; //判斷桶是否存在，如果不存在則創建桶，否則上傳文件會異常 var exists = await MinioHelper.BucketExists(minio, buckName); if (!exists) { //創建桶 await MinioHelper.MakeBucket(minio, buckName); } //上傳文件（桶下面可以自定義文件夾。如：1027/20211027001.jpg 則會創建一個1027文件夾） var result = await MinioHelper.FPutObject(minio, buckName, "1027/20211027001.png", "E:\\202110271417.png"); //下載文件地址：192.168.90.128:9000+桶名稱+文件名稱 } catch (Exception ex) { string str = ex.Message; } }
minio文件操作幫助類
