FastDFS

下载必要安装包

wget -c "https://github.com/happyfish100/fastdfs/archive/V6.06.tar.gz"
wget -c "https://github.com/happyfish100/libfastcommon/archive/V1.0.43.tar.gz"
wget -c "https://github.com/happyfish100/fastdfs-nginx-module/archive/V1.22.tar.gz"
Nginx

libfastcommon

解压后放到/usr/local ./make.sh && ./make.sh install

fastdfs

解压后放到/usr/local ./make.sh && ./make.sh install

cd /etc/fdfs/
cp storage.conf.sample storage.conf
cp client.conf.sample client.conf
cp tracker.conf.sample tracker.conf
mkdir -p /fastdfs/tracker
mkdir -p /fastdfs/storage

tracker配置

vi /etc/fdfs/tracker.conf

base_path = /fastdfs/tracker

启动tracker：/etc/init.d/fdfs_trackerd start
停止tracker：/etc/init.d/fdfs_trackerd stop

storage配置

vi /etc/fdfs/storage.conf

base_path = /fastdfs/storage 
store_path0 = /fastdfs/storage
tracker_server = tracker的IP:22122
http.server_port = 80

启动storage：/etc/init.d/fdfs_storaged start

client配置（开发不需要）

vi /etc/fdfs/client.conf

base_path = /fastdfs/tracker
tracker_server = tracker的IP:22122

#设置开机启动：vi /etc/rc.d/rc.local

/etc/init.d/fdfs_trackerd start
/etc/init.d/fdfs_storaged start

fastdfs-nginx-module 和 Nginx

fastdfs-nginx-module解压后放到/usr/local

nginx添加模块（解压目录，不是nginx主目录）
./configure --prefix=/usr/local/nginx --with-http_stub_status_module

fastdfs-nginx-module配置文件修改并将config文件中的/usr/local替换成/usr：cd /usr/local/fastdfs-nginx-module-1.22/src/ vi config

nginx添加模块：./configure --add-module=/usr/local/fastdfs-nginx-module-1.22/src/

nginx编译安装：make && make install

fastdfs-nginx-module配置文件复制
cp /usr/local/fastdfs-nginx-module-1.22/src/mod_fastdfs.conf /etc/fdfs/
并修改配置文件
vi /etc/fdfs/mod_fastdfs.conf

connect_timeout=10
tracker_server=IP:22122
url_have_group_name=true
store_path0=/fastdfs/storage

进入fastdfd的conf目录, 将http.conf，mime.types两个文件拷贝到/etc/fdfs/目录下
cp http.conf mime.types /etc/fdfs/

创建一个软连接，在/fastdfs/storage文件存储目录下创建软连接，将其链接到实际存放数据的目录
ln -s /fastdfs/storage/data/ /fastdfs/storage/data/M00

修改nginx.conf
vi /usr/local/nginx/conf/nginx.conf

server {listen       80;server_name  IP;location ~/group([0-9])/M00 {root  /fastdfs/storage/data;ngx_fastdfs_module;}
}

启动nginx
根据路径访问文件

使用

pom

com.github.tobatofastdfs-client1.26.7

application

fdfs.so-timeout = 1501
fdfs.connect-timeout = 601
fdfs.thumb-image.width= 150
fdfs.thumb-image.height= 150
fdfs.tracker-list=IP:22122
fdfs.web-server-url=IP:23001/

service

@Component
public class FastDFSClient {@Autowiredprivate FastFileStorageClient storageClient;@Autowiredprivate FdfsWebServer fdfsWebServer;/*** 上传文件* @param file 文件对象* @return 文件访问地址* @throws IOException*/public String uploadFile(MultipartFile file) throws IOException {StorePath storePath = storageClient.uploadFile(file.getInputStream(), file.getSize(), FilenameUtils.getExtension(file.getOriginalFilename()),null);return fdfsWebServer.getWebServerUrl() + storePath.getFullPath();//完整url}/*** 下载文件* @param fileUrl 文件url* @return*/public byte[]  download(String fileUrl) {String group = fileUrl.substring(0, fileUrl.indexOf("/"));String path = fileUrl.substring(fileUrl.indexOf("/") + 1);byte[] bytes = storageClient.downloadFile(group, path, new DownloadByteArray());return bytes;}/*** 删除文件* @param fileUrl 文件访问地址* @return*/public void deleteFile(String fileUrl) {if (StringUtils.isEmpty(fileUrl)) {return;}try {StorePath storePath = StorePath.parseFromUrl(fileUrl);storageClient.deleteFile(storePath.getGroup(), storePath.getPath());} catch (FdfsUnsupportStorePathException e) {logger.warn(e.getMessage());}}
}

controller

@RestController
public class FastDFSController {@Autowiredprivate FastDFSClient fastDFSClient;@PostMapping("/upload")public String uploadFile(@RequestParam("file") MultipartFile file) throws IOException {byte[] bytes = file.getBytes();String originalFileName = file.getOriginalFilename();String extension = FilenameUtils.getExtension(file.getOriginalFilename());String fileName = file.getName();long fileSize = file.getSize();System.out.println(originalFileName + "==========" + fileName + "===========" + fileSize + "===============" + extension + "===========" + bytes.length);return fastDFSClient.uploadFile(file);}@PostMapping("/download")public void downloadFile(@RequestParam("fileUrl")String fileUrl, HttpServletResponse response) throws IOException {byte[] bytes = fastDFSClient.download(fileUrl);// 这里只是为了整合fastdfs，所以写死了文件格式。需要在上传的时候保存文件名。下载的时候使用对应的格式response.setHeader("Content-disposition", "attachment;filename=" + URLEncoder.encode("1.jpg", "UTF-8"));response.setCharacterEncoding("UTF-8");ServletOutputStream outputStream = null;try {outputStream = response.getOutputStream();outputStream.write(bytes);} catch (IOException e) {e.printStackTrace();} finally {try {outputStream.flush();outputStream.close();} catch (Exception e) {e.printStackTrace();}}}@GetMapping("/deleteFile")public String deleteFile(@RequestParam("fileUrl")String fileUrl) {fastDFSClient.deleteFile(fileUrl);return "success";}
}
