本身閒着沒事,在小黑上虛擬了 4 個 centos 64 的系統,用來安裝分佈式 fastdfs 、 nginx 負載均衡,過程一路艱辛,搞了一個通宵都沒弄好,終於在次日的傍晚終於弄好了,記錄一下過程。
有時候看書會犯糊塗,看完了都不知道將了啥,只有動手坐坐,啥玩意都明白差很少了。
有時候太懶了,哎,這是病,得治。
FastDFS協議:
FastDFS角色間是基於TCP/IP協議進行通訊,協議包格式爲:header + body。具體結構如圖:
上傳機制:
同步時間管理:
當一個文件上傳成功後,客戶端立刻發起對該文件下載請求(或刪除請求)時,tracker是如何選定一個適用的存儲服務器呢?其實每一個存儲服務器都須要定時將自身的信息上報給tracker,這些信息就包括了本地同步時間(即,同步到的最新文件的時間戳)。而tracker根據各個存儲服務器的上報狀況,就可以知道剛剛上傳的文件,在該存儲組中是否已完成了同步。同步信息上報以下圖
下載機制:
精巧的FID:
說到下載就不得不提文件索引(又稱:FID)的精巧設計了。文件索引結構以下圖,是客戶端上傳文件後存儲服務器返回給客戶端,用於之後訪問該文件的索引信息。文件索引信息包括:組名,虛擬磁盤路徑,數據兩級目錄,文件名。

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爲group2的源服務器 注意: 1.group2同組的Storage2和Storage3 FastDFS服務端口必須一致: port=23000。 2.一臺服務器能夠裝多個組(group)但不能裝同組的多個Storage,日誌會報錯誤,日誌報錯緣由是"注意1" 3.Version 4.05以前fastdfs內部綁定了libevent做爲http服務器.Version 4.05以後的版本刪除了內置的web http服務,內置的web http服務是個累贅,不用也罷! 4.啓動storage server時,一直處於僵死狀態.啓動storage server,storage將鏈接tracker server,若是連不上,將一直重試。直到鏈接成功,啓動纔算真正完成!若是集羣中有2臺tracker server,而其中一臺tracker沒有啓動,可能會致使storage server一直處於僵死狀態

1.安裝libevent 和 fastdfs 前端
libevent是一個事件觸發、異步事件的網絡庫,是一個輕量級的開源高性能網絡庫,以BSD許可證發佈,適用於Windows、Linux、BSD、Mac OS等多種平臺,內部使用select、epoll等系統調用。
