安装问题是典型的无意义的重复劳动，理应简单，一个软件应该让使用者更专注于软件的用法和配置文件，而不是安装过程。
fastdfs官方的spec文件功能不够完整,仅仅能够完成rpm打包,但是rpm包安装时会有各种问题。极少看到有人反馈spec文件问题，估计使用rpm包进行安装的，只有我一人。而使用rpm安装，可以省略重复无意义且容易出错的编译过程，提升软件安装体验。

我对官方的spec文件进行了大幅改造，对默认配置文件也进行了适当调整，改进如下：
1、启动脚本
/usr/bin/stop.sh 和/usr/bin/restart.sh 名字过于霸气，抛弃!
原fdfs_trackerd和fdfs_storaged启动脚本由于调用/usr/bin/stop.sh /usr/bin/restart.sh
新的启动脚本改为调用 /etc/rc.d/init.d/functions 公共函数进行启动、关闭和重启。
2、运行身份
配置文件相关选项默认为空，即探测当前用户身份，这容易误导使用者用root运行程序而造成安全隐患。rpm包安装时会创建普通用户fdfs，配置文件改为，run_by_user=fdfs和run_by_group=fdfs
使用root身份执行启动脚本，程序会自动切换到fdfs用户身份。
4、路径问题
配置文件中的路径，统一归于/var/lib/fastdfs之下，属主fdfs，比如/etc/fdfs/storage.conf
base_path=/var/lib/fastdfs/storage
5、将打包后的二进制包fastdfs-server 拆分成fastdfs-tracker 和fastdfs-storage，便于分别部署。
6、配置文件微调
文件名去掉sample后缀，直接使用conf文件，
将可能被修改的参数放入配置文件前面，方便查找。
附上修改后的fastdfs.spec文件如下：

如果将srpm包经过重新编译，也适用于CentOS 6
