CentOS7安装MinIO教程,并在C#客户端WPF中实现监控上传进度

MinIO的详细介绍可以参考官网(https://min.io/product/overview)。

简单来说它是一个实现了AWS S3标准的100%开源的,可商用的( Apache V2 license),高性能的分布式对象存储管理系统。

AWS S3是什么(https://zhuanlan.zhihu.com/p/112057573):

  1. 提供了统一的接口 REST/SOAP 来统一访问任何数据
  2. 对 S3 来说,存在里面的数据就是对象名(键),和数据(值)
  3. 不限量,单个文件最高可达 5TB
  4. 高速。每个 bucket 下每秒可达 3500 PUT/COPY/POST/DELETE 或 5500 GET/HEAD 请求
  5. 具备版本,权限控制能力
  6. 具备数据生命周期管理能力

这次主要介绍CentOS7如何安装MinIO,以及C#如何使用MinIO的.NET SDK来上传文件(显示上传进度)。

首先安装好CentOS7 64位操作系统,然后在/usr/local下新建一个minio目录,在minio目录下新建三个子文件夹,分别是:

bin 用来保存minio的主程序

data 用来保存用户上传的文件

etc 用来保存minio的配置文件

然后新建MinIO运行所需的系统组和用户

groupadd -g 2020 minio useradd -r -M -u 2020 -g 2020 -c "Minio User" -s /sbin/nologin  minio

建立了一个组ID是2020,名称是minio的系统组,然后添加了一个不能登录的名称是minio,所属组ID是2020并且个人ID也是2020的系统用户。

MinIO默认提供的http访问端口是9000,我们提前在防火墙里把9000端口打开

firewall-cmd --zone=public --add-port=9000/tcp --permanent firewall-cmd --reload

同时我们需要给MinIO挂载要给存储空间比较大的磁盘用来存储文件

执行lvdisplay找到比较大的分区,挂载给/usr/local/minio目录

运行

mount /dev/centos/home /usr/local/minio

把这个200多G的逻辑卷挂载给minio的目录。

同时为了重启后自动挂载,我们需要执行以下代码

vim /etc/fstab

把centos-home这句换成以下内容,保存退出,就可以让系统重启后自动挂载空间到/usr/local/minio目录了

/dev/mapper/centos-home /usr/local/minio        xfs     defaults        0 0

然后我们运行lsblk就可以看到磁盘空间正确挂载在minio目录下了

 从官网(或者通过下载工具下载到本地后上传)下载(https://min.io/download#/linux)到CentOS的/usr/local/minio/bin目录下

其中第二句(chmod +x minio)等把minio文件移动到/usr/local/minio/bin后在执行

第三句先不要执行

下面我们建立MinIO的配置文件

vim /usr/local/minio/etc/minio.conf

写入以下内容(–address后面的IP 是CentOS的IP地址)

MINIO_VOLUMES="/usr/local/minio/data" MINIO_OPTS="-C /usr/local/minio/etc --address 192.168.127.131:9000

建立MinIO的service文件,让它随系统启动而启动

vim /etc/systemd/system/minio.service 

写入以下内容

[Unit] Description=MinIO Documentation=https://docs.min.io Wants=network-online.target After=network-online.target AssertFileIsExecutable=/usr/local/minio/bin/minio  [Service] # User and group User=minio Group=minio  EnvironmentFile=/usr/local/minio/etc/minio.conf ExecStart=/usr/local/minio/bin/minio server $MINIO_OPTS $MINIO_VOLUMES  # Let systemd restart this service always Restart=always  # Specifies the maximum file descriptor number that can be opened by this process LimitNOFILE=65536  # Disable timeout logic and wait until process is stopped TimeoutStopSec=infinity SendSIGKILL=no  [Install] WantedBy=multi-user.target

然后我们启动MinIO

systemctl enable minio.service systemctl start minio.service systemctl status minio.service

启动正常后,我们访问http://192.168.127.131:9000就应该可以看到web管理端的登录界面

 我们可以通过下面的命令来获取到默认的登录名和密码(minioadmin)

cat /usr/local/minio/data/.minio.sys/config/config.json

 CentOS7安装MinIO教程,并在C#客户端WPF中实现监控上传进度

如果要自定义登录名和密码,可以在/usr/local/minio/etc/minio.conf中增加两个配置内容

MINIO_ACCESS_KEY=”登录名”
MINIO_SECRET_KEY=”登录密码”

至此,MinIO的安装就介绍完毕,下面是本文重点,C#中使用WPF客户端如何获取文件上传时的进度。

首先新建一个项目MinIO,项目类型是WPF,项目的.NET版本是4.6

引用官方的Minio .NET SDK以及其它一些需要的类库

CentOS7安装MinIO教程,并在C#客户端WPF中实现监控上传进度

在项目的根目录添加一个nlog.config并设置为较新时复制,内容如下(主要用来做一些日志记录):

<?xml version="1.0" encoding="utf-8" ?> <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd"       autoReload="true"       throwExceptions="false"       internalLogLevel="Info">     <targets>         <default-target-parameters xsi:type="File" createDirs="true" keepFileOpen="true" autoFlush="false" openFileFlushTimeout="10" openFileCacheTimeout="30" archiveAboveSize="10240" archiveNumbering="Sequence" concurrentWrites="true" encoding="UTF-8"/>         <target xsi:type="File" name="InfoFile" fileName="${basedir}/InfoLogs/log.txt" archiveFileName="${basedir}/InfoLogs/log.{#}.txt">             <layout xsi:type="JsonLayout">                 <attribute name="counter" layout="${counter}" />                 <attribute name="time" layout="${longdate}" />                 <attribute name="level" layout="${level:upperCase=true}"/>                 <attribute name="message" layout="${message:format=message}" encode="false" />             </layout>         </target>         <target xsi:type="File" name="ErrorFile" fileName="${basedir}/ErrorLogs/log.txt" archiveFileName="${basedir}/ErrorLogs/log.{#}.txt">             <layout xsi:type="JsonLayout">                 <attribute name="time" layout="${longdate}" />                 <attribute name="level" layout="${level:upperCase=true}"/>                 <attribute name="message" layout="${message}" encode="false" />                 <attribute name="exception">                     <layout xsi:type="JsonLayout">                         <attribute name="callsite" layout="${callsite}" />                         <attribute name="callsite-linenumber" layout="${callsite-linenumber} " />                     </layout>                 </attribute>             </layout>         </target>     </targets>     <rules>         <logger name="*" minlevel="Info" writeTo="InfoFile" />         <logger name="*" minlevel="Error" writeTo="ErrorFile" />     </rules> </nlog>

在使用过程中发现MinIO的.NET SDK中并没有回显上传进度的地方(如果有请告知),经过一些摸索,在它暴露的日志记录的地方获取到当前上传文件块的编号,通过MVVM的Messenger传递给主程序,主程序接收后计算出当前进度并显示出来。

我们在App.xaml中添加一个启动事件App_OnStartup,在启动的时候初始化一下Nlog,并定义一下MinIO上传时遇到大文件分块的默认值(5MB)

namespace MinIO {     /// <summary>     /// App.xaml 的交互逻辑     /// </summary>     public partial class App : Application     {         public static NLog.Logger NewNLog;         public static long MinimumPartSize = 5 * 1024L * 1024L;//单次上传文件请求最大5MB          private void App_OnStartup(object sender, StartupEventArgs e)         {             NewNLog = NLog.LogManager.GetLogger("MinIOLoger");         }     } }

 在MainWindow.xaml中我们添加一个按钮用来上传文件,一个TextBlock用来显示上传文件信息和进度

<Window x:Class="MinIO.MainWindow"         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"         xmlns:d="http://schemas.microsoft.com/expression/blend/2008"         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"         xmlns:local="clr-namespace:MinIO"         mc:Ignorable="d"         DataContext="{Binding FileUploadViewModel,Source={StaticResource Locator}}"         Title="MainWindow" Height="450" Width="800" Loaded="MainWindow_OnLoaded">     <Grid>         <Button Content="上传文件" HorizontalAlignment="Left" Margin="47,51,0,0" VerticalAlignment="Top" Width="75" Click="ButtonUpload_Click"/>         <TextBlock HorizontalAlignment="Left" Margin="47,158,0,0" TextWrapping="Wrap" VerticalAlignment="Top">             <Run Text=" 文件名:"></Run>             <Run Text="{Binding Path=FileName}"></Run>             <Run Text="&#13;&#10;"></Run>              <Run Text="文件大小:"></Run>             <Run Text="{Binding Path=FileSize}"></Run>             <Run Text="&#13;&#10;"></Run>              <Run Text="上传进度:"></Run>             <Run Text="{Binding Path=UploadProcess}"></Run>          </TextBlock>      </Grid> </Window>

同时我们定义一个ViewModel来实现文件上传信息变化时的通知(ViewModel目录中新建一个FileUploadViewModel.cs)

using System.ComponentModel;  namespace MinIO.ViewModel {     public class FileUploadViewModel : INotifyPropertyChanged     {         public event PropertyChangedEventHandler PropertyChanged;          private string _filename { get; set; }         /// <summary>         /// 文件名         /// </summary>         public string FileName         {             get => _filename;             set             {                 _filename = value;                 PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("FileName"));             }         }          private long _fileSize { get; set; }         /// <summary>         /// 文件大小         /// </summary>         public long FileSize         {             get => _fileSize;             set             {                 _fileSize = value;                 PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("FileSize"));             }         }          private long _partNumber { get; set; }         /// <summary>         /// 当前上传块         /// </summary>         public long PartNumber         {             get => _partNumber;             set             {                 _partNumber = value;                 PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("PartNumber"));             }         }          private long _totalParts { get; set; }         /// <summary>         /// 文件全部块数         /// </summary>         public long TotalParts         {             get => _totalParts;             set             {                 _totalParts = value;                 PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("TotalParts"));             }         }          private string _uploadProcess { get; set; }         /// <summary>         /// 上传进度展示         /// </summary>         public string UploadProcess         {             get => _uploadProcess;             set             {                 _uploadProcess = value;                 PropertyChanged?.Invoke(this,new PropertyChangedEventArgs("UploadProcess"));             }         }     } }

同时为了能让MinIO根据不同的文件类型展示不同的图标,我们还需要建立一个ContentType对应关系类(ContentTypeHelper.cs)

using System.Collections.Generic;  namespace MinIO.Helper {     public static class ContentTypeHelper     {         private static readonly Dictionary<string,string> DictionaryContentType=new Dictionary<string, string>         {             {"default","application/octet-stream"},             {"bmp","application/x-bmp"},             {"doc","application/msword"},             {"docx","application/msword"},             {"exe","application/x-msdownload"},             {"gif","image/gif"},             {"html","text/html"},             {"jpg","image/jpeg"},             {"mp4","video/mpeg4"},             {"mpeg","video/mpg"},             {"mpg","video/mpg"},             {"ppt","application/x-ppt"},             {"pptx","application/x-ppt"},             {"png","image/png"},             {"rar","application/zip"},             {"txt","text/plain"},             {"xls","application/x-xls"},             {"xlsx","application/x-xls"},             {"zip","application/zip"},         };         /// <summary>         /// 根据文件扩展名(不含.)返回ContentType         /// </summary>         /// <param name="fileExtension">文件扩展名(不包含.)</param>         /// <returns></returns>         public static string GetContentType(string fileExtension)         {             return DictionaryContentType.ContainsKey(fileExtension) ? DictionaryContentType[fileExtension] : DictionaryContentType["default"];         }             } }

我们需要新建一个实现MinIO中IRequestLogger接口的类(LogHelper.cs),用来接收日志信息通过处理日志信息,来计算出当前上传进度信息

using GalaSoft.MvvmLight.Messaging; using Minio; using Minio.DataModel.Tracing; using System.Net;  namespace MinIO.Helper {     public class LogHelper : IRequestLogger     {         public void LogRequest(RequestToLog requestToLog, ResponseToLog responseToLog, double durationMs)         {             if (responseToLog.statusCode == HttpStatusCode.OK)             {                 foreach (var header in requestToLog.parameters)                 {                     if (!string.Equals(header.name, "partNumber")) continue;                     if(header.value==null) continue;                     int.TryParse(header.value.ToString(), out var partNumber);//minio遇到上传文件大于5MB时,会进行分块传输,这里就是当前块的编号(递增)                     Messenger.Default.Send(partNumber, "process");//发送给主界面计算上传进度                     break;                 }             }         }     } }

在MainWindow初始化的时候初始化MinIO的配置信息,同时用MVVM的Messenger来接收当前上传的块编号,用来计算上传进度。

using GalaSoft.MvvmLight.Messaging; using Microsoft.Win32; using Minio; using Minio.Exceptions; using MinIO.Helper; using MinIO.ViewModel; using System; using System.Diagnostics; using System.IO; using System.Threading.Tasks; using System.Windows;  namespace MinIO {     /// <summary>     /// MainWindow.xaml 的交互逻辑     /// </summary>     public partial class MainWindow : Window     {         private static string _endpoint = "192.168.127.131:9000";//minio服务器地址         private static string _accessKey = "minioadmin";//授权登录账号         private static string _secretKey = "minioadmin";//授权登录密码         private static MinioClient _minioClient;          public MainWindow()         {             InitializeComponent();         }         private void MainWindow_OnLoaded(object sender, RoutedEventArgs e)         {             _minioClient = new MinioClient(_endpoint, _accessKey, _secretKey);             Messenger.Default.Register<int>(this, "process", obj =>              {                  try                  {                      Debug.WriteLine($"当前块编号:{obj}");                      if (obj == 0)                      {                          ViewModelLocator.Instance.FileUploadViewModel.UploadProcess = "0.00%";                          return;                      }                      ViewModelLocator.Instance.FileUploadViewModel.PartNumber = obj;                       ViewModelLocator.Instance.FileUploadViewModel.UploadProcess =                          $"{(float)ViewModelLocator.Instance.FileUploadViewModel.PartNumber / ViewModelLocator.Instance.FileUploadViewModel.TotalParts:P2}";//计算文件上传进度                  }                  catch (Exception exception)                  {                      App.NewNLog.Error($"计算上传进度时出错:{exception}");                  }              });         }         private void ButtonUpload_Click(object sender, RoutedEventArgs e)         {             var open = new OpenFileDialog             {                 CheckFileExists = true,                 CheckPathExists = true,             };             if (open.ShowDialog(this) == false)             {                 return;             }              ViewModelLocator.Instance.FileUploadViewModel.FileName = open.SafeFileName;             try             {                 Dispatcher?.InvokeAsync(async () =>                 {                     await Run(_minioClient, "test", open.FileName, ViewModelLocator.Instance.FileUploadViewModel.FileName);                 });             }             catch (Exception ex)             {                 Console.WriteLine(ex.Message);             }         }          private static async Task Run(MinioClient minio, string userBucketName, string uploadFilePath, string saveFileName)         {             var bucketName = userBucketName;             var location = "us-east-1";             var objectName = saveFileName;             var filePath = uploadFilePath;             var contentType = ContentTypeHelper.GetContentType(saveFileName.Substring(saveFileName.LastIndexOf('.') + 1));             var file = new FileInfo(uploadFilePath);              try             {                 var found = await minio.BucketExistsAsync(bucketName);                 if (!found)                 {                     await minio.MakeBucketAsync(bucketName, location);                 }                  _minioClient.SetTraceOn(new LogHelper());//我们在上传开始的时候,打开日志,通过日志抛出的块编号来计算出当前进度                  ViewModelLocator.Instance.FileUploadViewModel.FileSize = file.Length;                 ViewModelLocator.Instance.FileUploadViewModel.TotalParts = file.Length / App.MinimumPartSize + 1;//计算出文件总块数                  await minio.PutObjectAsync(bucketName, objectName, filePath, contentType);//上传文件                 Debug.WriteLine("Successfully uploaded " + objectName);              }             catch (MinioException e)             {                 App.NewNLog.Error($"File Upload Error: {e}");                 Debug.WriteLine($"File Upload Error: {e.Message}");             }             finally             {                 _minioClient.SetTraceOff();             }         }     } }

具体效果如下:
