一、docker 安装FastDFS
1、拉取镜像
docker pull morunchang/fastdfs
2、创建并启动tracker容器
docker run -d --name=tracker -v /home/fastdfs_docker/fdfs/tracker:/data/fast_data --privileged=true --net=host morunchang/fastdfs sh tracker.sh
3、创建并启动storage容器、此处只做单机版测试
注意：由于tracker容器使用host网络模式、与宿主公用network namespace, 因此tracker容器ip与宿主机ip一致
docker run -d --name=storage -v /home/fastdfs_docker/fdfs/storage_data:/data/fast_data --privileged=rue --net=host -e TRACKER_IP=[宿主机ip]: -e GROUP_NAME=group1 morunchang/fastdfs sh storage.sh
二、java客户端测试
1、创建maven测试工程
pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<artifactId>commons-io</artifactId>
</dependency>
</dependencies> </project>
2、在classpath:config下创建fastdfs-client.properties文件
fastdfs-client.properties
fastdfs.connect_timeout_in_seconds = 5 #http连接超时时间
fastdfs.network_timeout_in_seconds = 60 #tracker 与 storage 通信连接超时时间
fastdfs.charset = UTF-8 #字符编码
fastdfs.tracker_servers = [tracker_server_ip]:22122 #tracker_server_ip
3、上传文件测试
/**
* 上传文件
* @throws Exception
*/
@Test
public void testUpload() throws Exception{ ClientGlobal.initByProperties("config/fastdfs-client.properties");
System.out.println("network_timeout=" + ClientGlobal.g_network_timeout + "ms");
System.out.println("charset=" + ClientGlobal.g_charset);
//创建客户端
TrackerClient tc = new TrackerClient();
//连接tracker Server
TrackerServer ts = tc.getConnection();
if (ts == null) {
System.out.println("getConnection return null");
return;
}
//获取一个storage server
StorageServer ss = tc.getStoreStorage(ts);
if (ss == null) {
System.out.println("getStoreStorage return null");
}
//创建一个storage存储客户端
StorageClient1 sc1 = new StorageClient1(ts, ss);
NameValuePair[] meta_list = null; //new NameValuePair[0];
String item = "C:\\Users\\degao\\Pictures\\111.png";
String fileid;
fileid = sc1.upload_file1(item, "png", meta_list);
System.out.println("Upload local file " + item + " ok, fileid=" + fileid);
}
4、查询文件信息测试
/**
* 查询文件
* @throws Exception
*/
@Test
public void testQueryFile() throws Exception{
ClientGlobal.initByProperties("config/fastdfs-client.properties");
TrackerClient tracker = new TrackerClient();
TrackerServer trackerServer = tracker.getConnection();
StorageServer storageServer = null;
StorageClient storageClient = new StorageClient(trackerServer,
storageServer);
FileInfo fileInfo = storageClient.query_file_info("group1",
"M00/00/00/rBsAAlwM58eAcFPfAAFs5SjEXRM444.png");
System.out.println(fileInfo);
}
5、下载文件测试
/**
* 下载文件
*/
@Test
public void testDownloadFile() throws Exception {
ClientGlobal.initByProperties("config/fastdfs-client.properties");
TrackerClient tracker = new TrackerClient();
TrackerServer trackerServer = tracker.getConnection();
StorageServer storageServer = null;
StorageClient1 storageClient1 = new StorageClient1(trackerServer,
storageServer);
byte[] result = storageClient1.download_file1("group1/M00/00/00/rBsAAlwM58eAcFPfAAFs5SjEXRM444.png");
File file = new File("d:/1.png");
FileOutputStream fileOutputStream = new FileOutputStream(file);
fileOutputStream.write(result);
fileOutputStream.close();
}
