FastDFS
docker 安装
1拉取镜像（已经内置Nginx）
docker pull delron/fastdfs
2 构建Tracker # 22122 => Tracker默认端口
docker run --name=tracker-server --privileged=true -p 22122:22122 -v /var/fdfs/tracker:/var/fdfs -d delron/fastdfs tracker
3 构建Storage # 23000 => Storage默认端口 # 8888 => 内置Nginx默认端口 # TRACKER_SERVER => 执行Tracker的ip和端口 # --net=host => 避免因为Docker网络问题导致外网客户端无法上传文件，因此使用host网络模式
docker run --name=storage-server --privileged=true -p 23000:23000 -p 8888:8888 -v /var/fdfs/storage:/var/fdfs -e TRACKER_SERVER=192.168.32.10:22122 -e GROUP_NAME=group1 --net=host -d delron/fastdfs storage
注意要修改成自己的ip地址
4 查看容器
docker ps
5 需要开启端口 腾讯云直接开启

6 前端
上传文件
7 点击上传
group1/M00/00/00/CgAYBmMyxbuAH_jjAAFDcPEL5NE630.png
8 访问
ip:8888/group1/M00/00/00/CgAYBmMyxbuAH_jjAAFDcPEL5NE630.png
9 如果出现文件大小限制在启动类下配置
@Bean
public MultipartConfigElement multipartConfigElement(){
MultipartConfigFactory factory = new MultipartConfigFactory();
factory.setMaxFileSize(DataSize.ofGigabytes(1));
factory.setMaxRequestSize(DataSize.ofGigabytes(1));
return factory.createMultipartConfig();
}
