FastDFS是一個開源的輕量級分散式檔案系統，它對檔案進行管理，功能包括：檔案儲存、檔案同步、檔案訪問（檔案上傳、檔案下載）等，解決了大容量儲存和負載均衡的問題。特別適合以檔案為載體的線上服務，如相簿網站、視訊網站等等。詳細介紹請自行百度(www.baidu.com)。

接下來我們就來具體配置和安裝，我的伺服器是LNMP

• 在此之前首先要確定LAMP或LNMP環境已經搭建好

FastDFS配置

root@test:~# cd /etc/fdfs/
root@test:/etc/fdfs/# ls

root@test
 
:/etc/fdfs/# cp client.conf.sample client.conf

其中tracker_server部分的IP為自己的tracker伺服器IP，如果沒有改成localhost也是可以的

FastDFS啟動

接下來就是激動人心的時刻了，輸入以下命令來啟動服務

root@test:~# /usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf start
root@test:~# /usr/bin/fdfs_storaged /etc/fdfs/storage.conf start

通過ps -ef | grep fdfs來檢視fdfs程序是否存在

root@test:~# ps -ef | grep fdfs
root      2973     1  0 11:16 ?        00:00:00 /usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf start
root      2988     1  0 11:16 ?        00:00:00 /usr/bin/fdfs_storaged /etc/fdfs/storage.conf start

至此PHP FastDFS擴充套件已經安裝完成，重啟伺服器後進行測試

php FastDFS測試驗證

root@test:~# /usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf start
root@test:~# /usr/bin/fdfs_storaged /etc/fdfs/storage.conf start
root@test:~# cp /root/fastdfs/php_client/fastdfs_test.php /usr/share/nginx/www/

然後用瀏覽器開啟，http://遠端伺服器地址/fasrdfs_test.php 
如果出現

5.08 fastdfs_tracker_make_all_connections result: 1 array(1) { ["group1"]=> array(12) { ["total_space"]=> int(80632) ... { ["color"]=> string(6) "yellow" ["font"]=> string(4) "Aris" ["size"]=> string(2) "32" } delete file group1/M00/00/00/cteDO1cCjI-ATDFJAAAAD61kmgs438.bin return: 1 bool(true) tracker_close_all_connections result: 1

則表示整個擴充套件已經安裝完成並可以使用了。 

常見錯誤及解決辦法

瀏覽器端測試時出現

5.08 fastdfs_tracker_make_all_connections result: bool(false) bool(false)

重啟伺服器後未啟動storage和tracker服務，解決辦法：

root@test:~# /usr/bin/fdfs_storaged /etc/fdfs/storage.conf start
