附件中有保存好的traker.conf文件，需要的可以进行下载 
配置完成之后，运行 

/usr/local/bin/fdfs_trackerd /etc/fdfs/tracker.conf

tracker端就可以运行成功了。 
可能出现的问题有两个 
1.base_path设置的目录不存在，如果报这个错误，需要按base_path的设置创建一个目录 
2.找不到libevent-2.0.so.5 
如果找不到这个，请确认安装时的安装位置 
一般这个库会安装到/usr/local/lib中 
而我们的fdfs_trackerd会到/usr/lib中去查找，所以使用 

ln -s /usr/local/lib/libevent-2.0.so.5 /usr/lib/libevent-2.0.so.5

将库加载到/usr/lib中就可以了
