分布式存储系统 FastDFS - 使用样例

搭建服务

我们使用docker进行搭建。

#拉取镜像
docker pull delron/fastdfs

#创建tracker容器
docker run -d --network=host --restart always --name tracker -v /var/fdfs/tracker:/var/fdfs delron/fastdfs tracker

#创建storage容器
docker run -d --network=host --restart always --name storage -e TRACKER_SERVER=192.168.56.11:22122 -v /var/fdfs/storage:/var/fdfs -e GROUP_NAME=group1 delron/fastdfs storage

#进入storage容器，到storage的配置文件中配置http访问的端口，配置文件在/etc/fdfs目录下的storage.conf。
docker exec -it storage /bin/bash

#默认的http端口为8888，可以修改也可以配置
# the port of the web server on this storage server
http.server_port=8888

#配置nginx，在/usr/local/nginx目录下，修改nginx.conf文件
#默认配置如下：

    server {
        listen       8888;
        server_name  localhost;
        location ~/group[0-9]/ {
            ngx_fastdfs_module;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root html;
        }
    }

#默认的存储路径为/var/fdfs/data

java client使用

server项目导入依赖：

<dependency>
    <groupId>com.github.tobato</groupId>
    <artifactId>fastdfs-client</artifactId>
    <version>1.26.7</version>
    <exclusions>
