Linux配置FastDfs（Docker)以及測試

1.需求知識與環境

• 瞭解Docker的基礎命令和基礎原理.
• Nginx，Fastdfs的基本結構與運行原理.
• Centos7.x，Docker安裝成功。
• 防火牆:開啓80,8080,22122,23000端口.

2.本文目的

• 講解如何用Docker快速配置FastDfs（分佈式文件管理系統)，因此關於Docker與Nginx,Fastdfs的知識不再談論.

3.阿里雲使用Docker配置FastDfs

// 啓動docker
service docker start
// 拉取fastDfs鏡像
docker pull morunchang/fastdfs
// 運行tracker
docker run -d --name FastDfs_Tracker --net=host morunchang/fastdfs sh tracker.sh
// 運行Storage
docker run -d --name FastDfs_Storage --net=host -e TRACKER_IP=你的公網Ip:22122 -e GROUP_NAME=group1 morunchang/fastdfs sh storage.sh
// 修改nginx的內容，防止攔截請求
// 進入Fastdfs中
docker exec -it FastDfs_Storage  /bin/bash
// 編輯nginx.conf內容
vim /data/nginx/conf/nginx.conf
// 添加以下內容
location /group1/M00 {
     proxy_next_upstream http_502 http_504 error timeout invalid_header;
     proxy_cache http-cache;
     proxy_cache_valid  200 304 12h;
     proxy_cache_key $uri$is_args$args;
     proxy_pass http://fdfs_group1;
     expires 30d;
 }
// 退出FastDfs
exit
// 重新啓動FastDfs_Storage
docker restart FastDfs_Storage

4.測試代碼

// 使用封裝的FastDFSClient工具類進行測試
@Test
	public void test() throws Exception{
        // 填寫配置文件的路徑絕對/相對路徑
		FastDFSClient fastDFSClient = new FastDFSClient("D:/workspaces-itcast/e3-manager-web/src/main/resources/conf/client.conf");
        // uploadFile返回存儲路徑
		String string = fastDFSClient.uploadFile("圖片路徑");
		System.out.println(string);
	}
// 控制檯信息
group1/M00/00/00/rBEbtVzRZl6ALUMBAACxCrxWSoU212.jpg

訪問URL=你的公網IP:8080+方法返回路徑；

5.測試需要的jar包和工具類

1. 上傳工具類

// 工具類源碼

import org.csource.common.NameValuePair;
import org.csource.fastdfs.ClientGlobal;
import org.csource.fastdfs.StorageClient1;
import org.csource.fastdfs.StorageServer;
import org.csource.fastdfs.TrackerClient;
import org.csource.fastdfs.TrackerServer;

public class FastDFSClient {

	private TrackerClient trackerClient = null;
	private TrackerServer trackerServer = null;
	private StorageServer storageServer = null;
	private StorageClient1 storageClient = null;
	// 需要把配置文件放在classpath下
	public FastDFSClient(String conf) throws Exception {
		if (conf.contains("classpath:")) {
			conf = conf.replace("classpath:", this.getClass().getResource("/").getPath());
		}
		ClientGlobal.init(conf);
		trackerClient = new TrackerClient();
		trackerServer = trackerClient.getConnection();
		storageServer = null;
		storageClient = new StorageClient1(trackerServer, storageServer);
	}
	
	/**
	 * 上傳文件方法
	 * <p>Title: uploadFile</p>
	 * <p>Description: </p>
	 * @param fileName 文件全路徑
	 * @param extName 文件擴展名，不包含（.）
	 * @param metas 文件擴展信息
	 * @return
	 * @throws Exception
	 */
	public String uploadFile(String fileName, String extName, NameValuePair[] metas) throws Exception {
		String result = storageClient.upload_file1(fileName, extName, metas);
		return result;
	}
	
	public String uploadFile(String fileName) throws Exception {
		return uploadFile(fileName, null, null);
	}
	
	public String uploadFile(String fileName, String extName) throws Exception {
		return uploadFile(fileName, extName, null);
	}
	
	/**
	 * 上傳文件方法
	 * <p>Title: uploadFile</p>
	 * <p>Description: </p>
	 * @param fileContent 文件的內容，字節數組
	 * @param extName 文件擴展名
	 * @param metas 文件擴展信息
	 * @return
	 * @throws Exception
	 */
	public String uploadFile(byte[] fileContent, String extName, NameValuePair[] metas) throws Exception {
		
		String result = storageClient.upload_file1(fileContent, extName, metas);
		return result;
	}
	
	public String uploadFile(byte[] fileContent) throws Exception {
		return uploadFile(fileContent, null, null);
	}
	
	public String uploadFile(byte[] fileContent, String extName) throws Exception {
		return uploadFile(fileContent, extName, null);
	}
}
