[root@ky_hs_252 mfs-1.6.27]# mkdir /usr/local/mfs
[root@ky_hs_252 mfs-1.6.27]# useradd mfs -s /sbin/nologin -u 513
[root@ky_hs_252 mfs-1.6.27]# ./configure --prefix=/usr/local/mfs --with-default-user=mfs --with-default-group=mfs --disable-mfsmaster
[root@ky_hs_252 mfs-1.6.27]# make && make install
安装完成后会在/usr/local/mfs/etc/mfs生成示例文件
需要一下2个：
mfschunkserver.cfg ：chunkserver配置文件
mfshdd.cfg：存储空间配置文件
#默认配置文件路径已经更改到/usr/local/mfs/etc/mfs/
测试配置2个共享：
[root@ky_hs_252 etc]# mkdir /mnt/{mfschunks1,mfschunks2}
[root@ky_hs_252 etc]# chown -R mfs:mfs /mnt/mfschunks1
[root@ky_hs_252 etc]# chown -R mfs:mfs /mnt/mfschunks2
[root@ky_hs_252 etc]# lvcreate -l 10000 -n mfschunks1 VolGroup
Logical volume "mfschunks1" created
[root@ky_hs_252 etc]# lvcreate -l 10000 -n mfschunks2 VolGroup
Logical volume "mfschunks2" created
[root@ky_hs_252 etc]# mkfs -t ext4 /dev/VolGroup/mfschunks1
[root@ky_hs_252 etc]# mkfs -t ext4 /dev/VolGroup/mfschunks2
[root@ky_hs_252 etc]# mount -t ext4 /dev/VolGroup/mfschunks1 /mnt/mfschunks1
[root@ky_hs_252 etc]# mount -t ext4 /dev/VolGroup/mfschunks2 /mnt/mfschunks2
[root@ky_hs_252 etc]# chown -R mfs.mfs /mnt/mfschunks1
[root@ky_hs_252 etc]# chown -R mfs.mfs /mnt/mfschunks2
建议是为每个共享分配一个单独的磁盘分区或lvm逻辑卷，也可以直接挂载目录(实际上就是把目录所在的分区或lv作为存储空间)但是会提示：hdd space manager: data folders '/mnt/mfschunks2/' and '/mnt/mfschunks1/' are on the same physical device (could lead to unexpected behaviours)
添加到mfshdd.cfg文件中:
/mnt/mfschunks1
chunkserver配置文件默认认为master的主机名是 :mfsmaster
修改hosts：
192.168.1.190 mfsmaster
启动：
[root@ky_hs_252 etc]# /usr/local/mfs/sbin/mfschunkserver start
working directory: /usr/local/mfs/var/mfs
can't create lockfile in working directory: EACCES (Permission denied)
mfs/mfschunkserver.cfg 由于编译是没有指定--with-default-user-mfs，所以生成的配置文件里运行用户是nobody，运行组是mfs，修改用户为mfs即可启动
[root@ky_hs_252 etc]# vim mfs/mfschunkserver.cfg
[root@ky_hs_252 etc]# /usr/local/mfs/sbin/mfschunkserver start
working directory: /usr/local/mfs/var/mfs

查看MASTER上的日志：
Aug 29 15:00:08 trunk_190 mfsmaster[21567]: chunkserver register begin (packet version: 5) - ip: 192.168.1.252, port: 9422

此时可以在master CGI页面看到相应的性息：
