文档服务 - Docker Spring Boot FastDFS 搭建一套分布式文件服务器，太强了！ - 《Java学习笔记》

正文
首先说一下从零开始自己去搭一个fastdfs有多不顺，搭起来步骤繁琐,很麻烦，后来看到有人把做好的docker镜像传出来了，那搭建起来就很容易了

1.第一步安装docker:
1.在root权限下


yum install -y docker-io #安装docker
service docker star #启动docker
docker -v  # 查看docker版本

2.拉取镜像


docker pull qbanxiaoli/fastdfs

3.启动fastdfs

docker run -d --restart=always --privileged=true --net=host --name=fastdfs -e IP=192.168.127.131 -e WEB_PORT=80 -v ${HOME}/fastdfs:/var/local/fdfs qbanxiaoli/fastdfs

IP 后面是你的服务器公网ip或者虚拟机的IP，-e WEB_PORT=80 指定nginx端口
测试fastdfs是否搭建成功


docker exec -it fastdfs /bin/bash
echo "Hello FastDFS!">index.html
fdfs_test /etc/fdfs/client.conf upload index.html

能返回url就意见搭建成功

这样fastdfs就搭建好啦

下面进入springboot整合部分

加入依赖


<dependency>
   <groupId>com.github.tobato</groupId>
   <artifactId>fastdfs-client</artifactId>
   <version>1.26.2</version>
</dependency>

在springboot启动类上加


@Import(FdfsClientConfig.class)
@EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING)

创建FastDFSClient工具类

配置yml文件

# 分布式文件系统fastdfs配置
fdfs:
  # socket连接超时时长
  soTimeout: 1500
  # 连接tracker服务器超时时长
  connectTimeout: 600
  pool:
    # 从池中借出的对象的最大数目
    max-total: 153
    # 获取连接时的最大等待毫秒数100
    max-wait-millis: 102
  # 缩略图生成参数，可选
  thumbImage:
    width: 150
    height: 150
  # 跟踪服务器tracker_server请求地址,支持多个，这里只有一个，如果有多个在下方加- x.x.x.x:port
  trackerList:
    - 192.168.127.131:22122
  #
  # 存储服务器storage_server访问地址
  web-server-url: http://192.168.127.131/
  spring:
    http:
      multipart:
        max-file-size: 100MB # 最大支持文件大小
        max-request-size: 100MB # 最大支持请求大小

测试类

@RunWith(SpringRunner.class)
@SpringBootTest
public class FileClientApplicationTests {
@Test
public void Upload() {
String fileUrl = this.getClass().getResource("/test.jpg").getPath();
File file = new File(fileUrl);
String str = FastDFSClient.uploadFile(file);
FastDFSClient.getResAccessUrl(str);
}
@Test
public void Delete() {
FastDFSClient.deleteFile("group1/M00/00/00/rBEAClu8OiSAFbN_AAbhXQnXzvw031.jpg");
}
}

运行测试类

返回的url就是能访问的地址

最后一张看效果
