注：mfschunkserver 服务器的主配置很简单，没有特殊要求只需要修改MASTER_HOST的地址即可。存储分区的配置选择一个独立的磁盘分区（分区必须大于1G）。
启动mfschunkserver
[root@chunkserver-1~]#/usr/local/mfs/sbin/mfschunkserver
[root@chunkserver-1~]#netstat-an|grep9420
tcp00192.168.108.161:15099192.168.108.108:9420ESTABLISHED
同时查看系统日志
Oct1417:53:45vm_web_1mfschunkserver[1992]:connecting…
Oct1417:53:45vm_web_1mfschunkserver[1992]:connectedtoMaster
说明已经和master服务器成功连接
再查看master的日志查看
Oct1417:59:00experimentmfsmaster[10132]:server1(192.168.108.161):usedspace:560484352(0GB),totalspace:4226125824(3GB),usage:13.26%

同样也说明有一台 chunkserver 与自己连接，并给出了使用空间和剩余磁盘空间
剩余的3台mfschunkserver利用同样的方法配置好后启动mfschunkserver程序，这时候再查看master系统日志：
Oct1615:27:00experimentmfsmaster[10132]:inodes:9

这里可以看到有4台chunkserver已经连接到了master

挂载MFS
mfsmount
[root@client~]#mkdir/mnt/mfs
[root@client~]#mfsmount-h192.168.108.108
*mfsmount默认情况下将分区加载到/mnt/mfs目录下。如果想加载到其他目录请利用-w参数。
