0.docker宿主机要安装在Linux操作系统上，macbook会有问题，macbook上使用--net=host模式不起作用，可以安装CentOS虚拟机在虚拟机中安装docker

1.创建容器

docker pull morunchang/fastdfs
docker run -d --name tracker --net=host morunchang/fastdfs sh tracker.sh
docker run -d --name storage --net=host -e TRACKER_IP=172.16.200.153:22122 -e GROUP_NAME=group1 morunchang/fastdfs sh storage.sh

172.16.200.153是docker宿主机的IP，因为使用--net=host模式，docker tracker的IP和宿主机的是同一个，不单独分配IP

2.修改storage配置

docker exec -it storage  /bin/bash

vi /data/nginx/conf/nginx.conf

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;
}

docker restart storage

3.测试

使用SpringBoot的测试功能
A.依赖：

<dependency>
        <groupId>org.csource</groupId>
        <artifactId>fastdfs-client-java</artifactId>
        <version>1.27-SNAPSHOT</version>
</dependency>

B.fastdfs配置文件fdfs_client.conf

connect_timeout = 600
network_timeout = 600
tracker_server = 172.16.200.153:22122

C.application.properties

spring.servlet.http.multipart.max-file-size=10MB
spring.servlet.http.multipart.max-request-size=10MB

D.测试代码

@Test
public void testdfs() throws IOException, MyException{
  ClientGlobal.init("/D/workspace/springcloudws/ws02/EpcData/fastdfsdemo/src/main/resources/fdfs_client.conf");
        TrackerClient trackerClient = new TrackerClient();
        TrackerServer trackerServer = trackerClient.getConnection();
        StorageServer storageServer = null;
        StorageClient storageClient = new StorageClient(trackerServer, storageServer);
        String[] strings = storageClient.upload_file("/D/car.jpg", "jpg", null);
        for (String str : strings) {
            System.out.println(str);
        }
    }

返回结果:
group1
