自己闲着没事,在小黑上虚拟了 4 个 centos 64 的系统,用来安装分布式 fastdfs 、 nginx 负载均衡,过程一路艰辛,搞了一个通宵都没弄好,终于在第二天的傍晚终于弄好了,记录一下过程。
有时候看书会犯糊涂,看完了都不知道将了啥,只有动手坐坐,啥玩意都明白差不多了。
有时候太懒了,哎,这是病,得治。
FastDFS协议:
FastDFS角色间是基于TCP/IP协议进行通信,协议包格式为:header + body。具体结构如图:
上传机制:
同步时间管理:
当一个文件上传成功后,客户端马上发起对该文件下载请求(或删除请求)时,tracker是如何选定一个适用的存储服务器呢?其实每个存储服务器都需要定时将自身的信息上报给tracker,这些信息就包括了本地同步时间(即,同步到的最新文件的时间戳)。而tracker根据各个存储服务器的上报情况,就能够知道刚刚上传的文件,在该存储组中是否已完成了同步。同步信息上报如下图
下载机制:
精巧的FID:
说到下载就不得不提文件索引(又称:FID)的精巧设计了。文件索引结构如下图,是客户端上传文件后存储服务器返回给客户端,用于以后访问该文件的索引信息。文件索引信息包括:组名,虚拟磁盘路径,数据两级目录,文件名。
ps:
Tracker Server 192.168.55.222 /home/tracker 端口:22122 Tracker Server 192.168.55.226 /home/tracker 端口:22122 Storage1 Server 192.168.55.223 group1 /home/storage 端口:23000 Storage4 Server 192.168.55.227 group1 /home/storage 端口:23000 Storage2 Server 192.168.55.224 group2 /home/storage 端口:23000 Storage3 Server 192.168.55.225 group2 /home/storage 端口:23000 #Storage2为group2的源服务器 注意: 1.group2同组的Storage2和Storage3 FastDFS服务端口必须一致: port=23000。 2.一台服务器可以装多个组(group)但不能装同组的多个Storage,日志会报错误,日志报错原因是"注意1" 3.Version 4.05之前fastdfs内部绑定了libevent作为http服务器.Version 4.05之后的版本删除了内置的web http服务,内置的web http服务是个累赘,不用也罢! 4.启动storage server时,一直处于僵死状态.启动storage server,storage将连接tracker server,如果连不上,将一直重试。直到连接成功,启动才算真正完成!如果集群中有2台tracker server,而其中一台tracker没有启动,可能会导致storage server一直处于僵死状态

1.安装libevent 和 fastdfs
libevent是一个事件触发、异步事件的网络库,是一个轻量级的开源高性能网络库,以BSD许可证发布,适用于Windows、Linux、BSD、Mac OS等多种平台,内部使用select、epoll等系统调用。
