fastDFS分布式文件系统的部署
安装libfastcommon
libfastcommon是FastDFS官方提供的，libfastcommon包含了FastDFS运行所需要的一些基础库。
将libfastcommonV1.0.7.tar.gz拷贝至/usr/local/下
cd /usr/local
tar -zxvf libfastcommonV1.0.7.tar.gz
cd libfastcommon-1.0.7
./make.sh
./make.sh install
注意：libfastcommon安装好后会自动将库文件拷贝至/usr/lib64下，由于FastDFS程序引用usr/lib目录所以需要将/usr/lib64下的库文件libfastcommon.so拷贝至/usr/lib下。
tracker编译安装
将FastDFS_v5.05.tar.gz拷贝至/usr/local/下
tar -zxvf FastDFS_v5.05.tar.gz
cd FastDFS
./make.sh
./make.sh install
安装成功将安装目录下的conf下的文件拷贝到/etc/fdfs/下。
配置
安装成功后进入/etc/fdfs目录
拷贝一份新的tracker配置文件：
cp tracker.conf.sample tracker.conf
修改tracker.conf
vi tracker.conf
base_path=/home/yuqing/FastDFS
改为：
base_path=/home/FastDFS
配置http端口：
http.server_port=80
启动
/usr/bin/fdfs_trackerd /etc/fdfs/tracker.conf restart
FastDFS--storage安装
进入/etc/fdfs目录：
拷贝一份新的storage配置文件：
cp storage.conf.sample storage.conf
修改storage.conf
vi storage.conf
group_name=group1
base_path=/home/yuqing/FastDFS改为：base_path=/home/FastDFS
store_path0=/home/yuqing/FastDFS改为：store_path0=/home/FastDFS/fdfs_storage
#如果有多个挂载磁盘则定义多个store_path，如下
#store_path1=.....
#store_path2=......
tracker_server=192.168.101.3:22122 #配置tracker服务器:IP
#如果有多个则配置多个tracker
tracker_server=192.168.101.4:22122
#配置http端口
http.server_port=80
启动
/usr/bin/fdfs_storage /etc/fdfs/storage.conf restart
上传图片测试
FastDFS安装成功可通过/usr/bin/fdfs_test测试上传、下载等操作。
修改/etc/fdfs/client.conf
base_path=/home/fastdfs
tracker_server=192.168.101.3:22122
tracker_server=192.168.101.4:22122
使用格式：
/usr/bin/fdfs_test 客户端配置文件地址 upload 上传文件
比如将/home下的图片上传到FastDFS中：
/usr/bin/fdfs_test /etc/fdfs/client.conf upload /home/tomcat.png
打印如下日志：
This is FastDFS client test program v5.05

http://192.168.101.5/group1/M00/00/00/wKhlBVVY2M-AM_9DAAAT7-0xdqM485_big.png就是文件的下载路径。
对应storage服务器上的
/home/fastdfs/fdfs_storage/data/00/00/wKhlBVVY2M-AM_9DAAAT7-0xdqM485_big.png文件。
