记录 Java 中 FastDFS的一次简单使用

环境搭建

环境准备

1. 下载gcc环境

   yum install -y gcc-c++
   

2. 下载两个依赖库

   yum -y install libevent
   

   cd /usr/local
   wget https://github.com/happyfish100/libfastcommon/archive/V1.0.43.tar.gz
   tar -zxvf V1.0.43.tar.gz
   cd libfastcommon-1.0.43/
   ./make.sh
   ./make.sh install
   

3. 下载安装包

   wget https://github.com/happyfish100/fastdfs/archive/V6.06.tar.gz
   tar -zxvf V6.06.tar.gz
   cd fastdfs-6.06/
   ./make.sh
   ./make.sh install
   cd conf/
   cp ./* /etc/fdfs/
   

启动Tracker

1. 配置

   cd /etc/fdfs
   cat tracker.conf
   # the base path to store data and log files
   base_path = /home/yuqing/fastdfs
   cd /home
   mkdir yuqing
   cd yuqing
   mkdir fastdfs
   chmod 777 /home/yuqing/fastdfs
   

2. 启动

   /usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf start
   

启动Storage

1. 配置

   vi /etc/fdfs/storage.conf
   ###
   #tracker_server = 192.168.209.121:22122
   #tracker_server = 192.168.209.122:22122
   tracker_server = 192.168.204.133:22122
   

2. 启动

   /usr/bin/fdfs_storaged /etc/fdfs/storage.conf start
   

Nginx安装

wget http://Nginx.org/download/Nginx-1.17.0.tar.gz
tar zxvf Nginx-1.17.0.tar.gz
cd cd Nginx-1.17.0
yum -y install pcre-devel
yum -y install openssl openssl-devel
./configure
make
make install
/usr/local/Nginx/sbin/Nginx

fastdfs-Nginx-module安装

cd /usr/local
wget https://github.com/happyfish100/fastdfs-Nginx-module/archive/V1.22.tar.gz
tar -zxvf V1.22.tar.gz
cp fastdfs-Nginx-module-1.22/src/mod_fastdfs.conf /etc/fdfs/
vi /etc/fdfs/mod_fastdfs.conf
#tracker_server=tracker:22122
tracker_server=127.0.0.1:22122
#url_have_group_name = false
url_have_group_name = true

重新编译安装Nginx

cd /usr/local/Nginx-1.17.0
./configure --add-module=/usr/local/fastdfs-Nginx-module-1.22/src
make
make install

##配置Nginx

vi /usr/local/Nginx/conf/Nginx.conf

LOCATIOn ~/group([0-9]) {
      ngx_fastdfs_module;
}

重启Nginx

lsof -i:80
kill -9 PID
/usr/local/Nginx/sbin/Nginx
ngx_http_fastdfs_set pid=15596[启动成功]

Java 客户端调用

1. 创建一个普通的 Maven 工程，添加如下依赖：

   <dependency>
       <groupId>net.oschina.zcx7878</groupId>
       <artifactId>fastdfs-client-java</artifactId>
       <version>1.27.0.0</version>
   </dependency>
   

2. 上传文件

   public static void uploadFile() {
           try {
               ClientGlobal.initByProperties("client.properties");
               TrackerClient trackerClient = new TrackerClient();
               TrackerServer trackerServer = trackerClient.getConnection();
               StorageServer storageServer = null;
               StorageClient1 storageClient = new StorageClient1(trackerServer,storageServer);
   
               String url = storageClient.upload_file1("C:\\Users\\qzf\\Desktop\\p.jpg", "jpg", @R_262_6633@
               System.out.println(url); // group1/M00/00/00/wKjMhV5h_QWAWXR0AACJiovU6KI120.jpg
   
           } catch (IOException E) {
               e.printstacktrace();
           } catch (MyException E) {
               e.printstacktrace();
           }

3. 下载文件

   public static void downloadFile() {
           try {
               ClientGlobal.initByProperties("client.properties");
               TrackerClient trackerClient = new TrackerClient();
               TrackerServer trackerServer = trackerClient.getConnection();
               StorageServer storageServer = null;
               StorageClient1 storageClient1 = new StorageClient1(trackerServer,storageServer);
               byte[] bytes = storageClient1.download_file1("group1/M00/00/00/wKjMhV5h_QWAWXR0AACJiovU6KI120.jpg");
               FiLeoutputStream fos = new FiLeoutputStream(new File("C:\\Users\\qzf\\Desktop\\pp.jpg"));
               fos.write(bytes);
               fos.close();
               } catch (IOException E) {
               e.printstacktrace();
           } catch (MyException E) {
               e.printstacktrace();
           }
       }
