有3个配置文件，所在的目录：/etc/fdfs
client.conf.sample storage.conf.sample tracker.conf.sample
复制上面的3个文件，文件名去掉sample
1，设置有效
# is this config file disabled # false for enabled # true for disabled disabled=false
2，绑定IP地址，不设置代表本机的所有IP地址
# bind an address of this host # empty for bind all addresses of this host bind_addr=
3，修改端口号
# the tracker server port port=22122
4，修改数据和日志的目录
#the base path to store data and log files base_path=/home/自己的用户名/文件夹名
1，
2，
3，
4，
和tracker一样
5，设置存储目录的数量和每个目录的实际路径
# path(disk or mount point) count, default value is 1 # 如果把下面的1修改为3，则store_path1和store_path2，就必须设置 store_path_count=1 # store_path#, based 0, if store_path0 not exists, it's value is base_path # the paths must be exist store_path0=/home/ys/fastdfs/storage #store_path1=/home/yuqing/fastdfs2
6，指定tracker进程所在的机器的IP和使用的端口
# tracker_server can ocur more than once, and tracker_server format is # "host:port", host can be hostname or ip address tracker_server=192.168.209.121:22122
7，设置当前节点所属的组
# the name of the group this storage server belongs to # # comment or remove this item for fetching from tracker server, # in this case, use_storage_id must set to true in tracker.conf, # and storage_ids.conf must be configed correctly. group_name=group1
1,修改数据和日志的目录
# the base path to store log files base_path=/home/ys/fastdfs/client
2,指定tracker进程所在的机器的IP和使用的端口
# tracker_server can ocur more than once, and tracker_server format is # "host:port", host can be hostname or ip address tracker_server=10.210.65.125:22122
fdfs_trackerd /etc/fdfs/tracker.conf
用下面的确认是否启动成功
ps aux | grep fdfs*
如果有下面的结果，说明启动成功。如果没有，去设置的log文件夹看trackerd.log文件里的错误消息。
ys 1260 0.2 0.2 90452 5804 ? Sl 22:15 0:00 fdfs_trackerd /etc/fdfs/tracker.conf
启动成功后，是守护进程。
重新启动或者停止的命令
sudo fdfs_trackerd /etc/fdfs/tracker.conf restart/stop
fdfs_storaged /etc/fdfs/storage.conf
用下面的确认是否启动成功
ps aux | grep fdfs*
如果有下面的结果，说明启动成功。如果没有，去设置的log文件夹看storaged.log文件里的错误消息。
ys 1352 0.0 0.1 85200 3424 ? Sl 22:26 0:00 fdfs_storaged /etc/fdfs/storage.conf
启动成功后，是守护进程。
重新启动或者停止的命令
sudo fdfs_storaged /etc/fdfs/storage.conf restart/stop
fdfs_monitor /etc/fdfs/client.conf
如果显示下面的结果，说明正常工作。
主要看storage是否是ACTIVE

这时，就可以上传和下载文件了
fdfs_upload_file /etc/fdfs/client.conf 要上传的文件
执行结果：
group1/M00/00/00/wKgAyF1dWGyAbQF1AAAACrGxDWg811.txt
group1/M00/00/00里的第一个00是文件夹，第二00也是文件夹,
去storage的【base_path=/home/自己的用户名/文件夹名】文件夹里，可以找到上传的文件。
fdfs_download_file /etc/fdfs/client.conf group1/M00/00/00/wKgAyF1dWGyAbQF1AAAACrGxDWg811.txt
指定上传时生产的【fdfs_download_file /etc/fdfs/client.conf group1/M00/00/00/wKgAyF1dWGyAbQF1AAAACrGxDWg811.txt】的名字，就能下载到本地。
