Docker + Spring Boot + FastDFS 搭建一套分布式文件服务器
首先说一下从零开始自己去搭一个fastdfs挺麻烦，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:
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
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 Spring Boot 整合部分
com.github.tobato
fastdfs-client
1.26.2
在 Spring Boot 启动类上加：
@Import(FdfsClientConfig.class)
@EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING)
创建FastDFSClient工具类
package com.yd.client.common;
import com.github.tobato.fastdfs.conn.FdfsWebServer;

配置yml文件
# 分布式文件系统fastdfs配置
fdfs:
# socket连接超时时长

# 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

# 缩略图生成参数，可选
thumbImage:

# 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:

#
# 存储服务器storage_server访问地址

**测试类**@RunWith(SpringRunner.class)@SpringBootTestpublic 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
