上一篇Centos7下FastDFS从安装到入门中讲述了FastDFS的安装以及概念。
但是这个服务不是基于http上传的方式，还需要特定去安装客户端，这个就不是很方便了。尤其在win10系统使用python去安装客户端是挺费劲的。
然后我从github找到了这个基于http上传的go-fastdfs，更加方便使用。无需安装客户端，python可以直接通过request进行http上传文件。
Github仓库
https://github.com/sjqzhang/go-fastdfs
查看当前的relases版本
访问 https://github.com/sjqzhang/go-fastdfs/releases
可以看到当前最新的版本就是 v1.3.1 ，下面使用Centos7系统来安装看看。
使用Centos7安装使用
下载并安装
mkdir go-fastdfs # 创建一个工作目录
cd go-fastdfs # 进入工作目录
# 下载二进制执行文件
wget --no-check-certificate https://github.com/sjqzhang/go-fastdfs/releases/download/v1.3.1/fileserver -O fileserver
chmod +x fileserver # 设置文件权限
./fileserver & # 启动服务
执行启动如下：
[root@centos7 go-fastdfs]# ls
conf data files fileserver log static
[root@centos7 go-fastdfs]#
[root@centos7 go-fastdfs]#
[root@centos7 go-fastdfs]# ./fileserver &
[1] 2180
[root@centos7 go-fastdfs]# Listen on :8080
[root@centos7 go-fastdfs]#
这样默认是启动8080端口号作为服务的。
curl命令上传
# 随便写一个txt文件，用来测试上传
[root@centos7 go-fastdfs]# echo 123 > 1.txt
[root@centos7 go-fastdfs]#
# 使用curl直接上传请求，可以看到返回了file id信息
[root@centos7 go-fastdfs]# curl -F file=@1.txt http://192.168.196.129:8080/upload
http://192.168.196.129:8080/group1/default/20190814/11/09/7/1.txt
[root@centos7 go-fastdfs]#
python3使用request库执行上传
[root@centos7 go-fastdfs]# ipython3

可以看到，go-fastdfs不会去修改文件的存储命名，其实这个也是很方便的。
查看日志
# 进入log目录下
[root@centos7 go-fastdfs]# cd log/
# 可以看到有三个日志文件
[root@centos7 log]# ls

如果只是单纯查看文件上传的记录，只需要看fileserver.log即可。

可以看到配置项还是挺多的，不过目前的需求就是能够上传、下载文件即可，所以其他配置有需要的时候上github仓库中查阅配置即可。
