1.FastDFS介紹
FastDFS是一款開源的輕量級分布式文件系統，
-純C實現，支持Linux，FreeBSD等UNIX系統，
-類goolge FS，不是通用的文件系統，只能通過專有API訪問，目前提供了C，java和PHP API
-為互聯網應用量身定做，追求高性能和高擴展
-FastDFS可以看做是基於文件的key value pair存儲系統，稱作為分布式文件存儲服務更合適

3.FastDFS上傳原理
- storage定時向tracker上傳狀態信息
- client上傳連接請求到tracker
- tracker查詢可用的storage，並返回storage的ip和端口
- 上傳文件fIlecontent和meta data
- 生成file_id，將上傳的內容寫入磁盤，並返回file_id路徑和文件名
4.安裝FastDFS依賴lib包
cd /usr/local/src/ git clone https://github.com/happyfish100/libfastcommon.git cd libfastcommon/ ./make.sh ./make.sh install
5.安裝FastDFS--v5.08
cd /usr/local/src wget http://nchc.dl.sourceforge.net/project/fastdfs/FastDFS%20Server%20Source%20Code/FastDFS%20Server%20with%20PHP%20Extension%20Source%20Code%20V5.08/FastDFS_v5.08.tar.gz tar -zxvf FastDFS_v5.08.tar.gz cd FastDFS ./make.sh ./make.sh install
6.tracker配置
sed -i 's#/usr/local/bin/#/usr/bin/#g' /etc/init.d/fdfs_trackerd mkdir -p /data/fastdfs/tracker cd /etc/fdfs/ cp tracker.conf.sample tracker.conf vim tracker.conf disabled=false #啟用配置文件 port=22122 #設置 tracker 的端口號 base_path=/data/fastdfs/tracker #設置 tracker 的數據文件和日志目錄（需預先創建） http.server_port=8888 #設置 http 端口號 http.server_port=8888 #指的是在tracker服務器上啟動http服務進程，如:apache或者nginx 啟動時所監聽的端口
/etc/init.d/fdfs_trackerd start
7.storage配置
sed -i 's#/usr/local/bin/#/usr/bin/#g' /etc/init.d/fdfs_storaged mkdir -p /data/fastdfs/base mkdir -p /data/fastdfs/data cd /etc/fdfs/ cp storage.conf.sample storage.conf vim storage.conf disabled=false #啟用配置文件 group_name=group1 #組名，根據實際情況修改 port=23000 #設置 storage 的端口號 base_path=/data/fastdfs/base #設置 storage 的日志目錄（需預先創建） store_path_count=1 #存儲路徑個數，需要和 store_path 個數匹配 store_path0=/data/fastdfs/date #存儲路徑 tracker_server=10.10.10.81:22122 #tracker 服務器的 IP 地址和端口號 http.server_port=8888 #設置storage上啟動的http服務的端口號，如安裝的nginx的端口號
/etc/init.d/fdfs_storage start
12.客戶端文件配置
[root@localhost fdfs]# cp client.conf.sample cilent.conf [root@img01 fdfs]# grep -Ev '^$|^#' /etc/fdfs/client.conf connect_timeout=30 network_timeout=60 base_path=/data/fastdfs/fdfs_client # 日志路徑 tracker_server=172.16.1.40:22122 # 追蹤服務器的IP，有多個服務器可以另一行 log_level=info use_connection_pool = false connection_pool_max_idle_time = 3600 load_fdfs_parameters_from_tracker=false use_storage_id = false storage_ids_filename = storage_ids.conf http.tracker_server_port=80
