首先server1下载软件包：
libpcap-1.4.0-4.20130826git2dbcaa1.el6.x86_64.rpm 依赖环境
libpcap-devel-1.4.0-4.20130826git2dbcaa1.el6.x86_64.rpm 依赖环境
moosefs-3.0.80-1.tar.gz
yum install -y rpm-build rpm包检测编译环境安装
rpmbuild -tb moosefs-3.0.80-1.tar.gz 查看编译软件包
其中可能要安装gcc编译环境
yum install gcc -y
做软连接ln -s moosefs-3.0.80-1.tar.gz moosefs-3.0.80.tar.gz
进入目录 cd /root/rpmbuild/RPMS/x86_64
[root@server1 x86_64]# yum install -y moosefs-master-3.0.80-1.x86_64.rpm moosefs-cgi-3.0.80-1.x86_64.rpm moosefs-cgiserv-3.0.80-1.x86_64.rpm
将客户端软件包发到server2和server3
scp moosefs-chunkserver-3.0.80-1.x86_64.rpm server2:/root/
scp moosefs-chunkserver-3.0.80-1.x86_64.rpm server3:/root/
[root@server1 x86_64]# cd /etc/mfs/
[root@server1 mfs]# vim mfsmaster.cfg 可默认不做修改，这里既不作修改
[root@server1 mfs]# vim /etc/hosts 注意mfs解析
172.25.35.1 server1 mfsmaster

[root@server1 x86_64]# pwd

[root@server1 x86_64]scp moosefs-client-3.0.80-1.x86_64.rpm root@172.25.35.250:/root/desktop 把客户端软件发给测试机（这里即是物理机稍后作测试使用）
[root@server2 ~]# rpm -ivh moosefs-chunkserver-3.0.80-1.x86_64.rpm
[root@server3 ~]# rpm -ivh moosefs-chunkserver-3.0.80-1.x86_64.rpm
server2,3 安装软件,注意解析，同server1
[root@server2 ~]# cd /etc/mfs/
[root@server2 mfs]# vim mfshdd.cfg
/mnt/chunk1 文档后面追加存储路径
[root@server2 mfs]# mkdir /mnt/chunk1/
[root@server2 mfs]# chown mfs.mfs /mnt/chunk1/
[root@server2 mfs]# mfschunkserver 启动，server3同server2，只要文件目录改为/mnt/chunk2和server2不同即可
给server2加一块硬盘： 装scsi服务
[root@server2 mfs]# yum install -y scsi- 安装scsi所有包
[root@server2 mfs]# vim /etc/tgt/targets.conf

backing-store /dev/vdb

root@server2 mfs]# /etc/init.d/tgtd start
正在启动 SCSI target daemon： [确定]
server1上：将新加这块硬盘挂上
[root@server1 x86_64]# iscsiadm -m discovery -t st -p 172.25.35.2
172.25.35.2:3260,1 iqn.2018-06.com.example:server.target1

[root@server1 x86_64]# fdisk -l 查看

[root@server1 x86_64]# fdisk -cu /dev/sda
[root@server1 x86_64]# mkfs.ext4 /dev/sda1 分区格式化
[root@server1 x86_64]# mount /dev/sda1 /mnt/
[root@server1 x86_64]# df 先挂载看下
[root@server1 x86_64]# cd /var/lib/mfs/
[root@server1 mfs]# mfsmaster stop 停掉服务
[root@server1 mfs]# cp -p /mnt/ 拷贝所有文文件到mnt下
[root@server1 mfs]# chown mfs.mfs /mnt/
[root@server1 mfs]# umount /mnt/
[root@server1 mfs]# mount /dev/sda1 /var/lib/mfs
[root@server1 mfs]# mfsmaster
[root@server1 mfs]# df
/dev/sda1 8255928 153132 7683420 2% /var/lib/mfs
因要实现高可用故server4上安装master 解析同server1
[root@server4 ~]# yum install -y moosefs-master-3.0.80-1.x86_64.rpm
[root@server4 ~]# yum install iscsi-
[root@server4 ~]# iscsiadm -m discovery -t st -p 172.25.35.2
172.25.35.2:3260,1 iqn.2018-06.com.example:server.target1
[root@server4 ~]# iscsiadm -m node -l

[root@server4 ~]# fdisk -l
回到前面说道的物理机：同样需要解析
[root@localhost ~]# rpm -ivh moosefs-client-3.0.80-1.x86_64.rpm
[root@localhost ~]# rpm -qa |grep moosefs
moosefs-client-3.0.80-1.x86_64 查看
[root@localhost ~]# cd /etc/mfs/
[root@localhost mfs]# vim mfsmount.cfg
/mnt/mfs
[root@localhost ~]# mfsmount
[root@localhost mfs]# df
mfsmaster:9421 34365120 4873600 29491520 15% /mnt/mfs
文件删除恢复
[root@localhost mfs]# mkdir dir{1..2}
[root@localhost mfs]# mfsgetgoal dir1/
dir1/: 2
[root@localhost mfs]# mfsgetgoal dir2/
dir2/: 2
[root@localhost mfs]# cd dir1
[root@localhost mfs]# cp /etc/passwd . 拷贝一些文件测试
[root@localhost mfs]# cd dir2
[root@localhost mfs]#cp /etc/fstab .
[root@localhost mfs]# cd dir1
[root@localhost dir1]# dd if=/dev/zero of=bigfile bs=1M count=200
写入一个大文件
[root@localhost dir1]# mfsfileinfo bigfile
[root@localhost dir1]# rm -f passwd
[root@localhost dir1]# mfsgettrashtime .
.: 86400
[root@localhost dir1]# cd /etc/mfs/
[root@localhost mfs]# cat /etc/mfs/mfsmount.cfg
[root@localhost mnt]# mkdir mfsmeta
[root@localhost mnt]# mfsmount -m /mnt/mfsmeta/
[root@localhost mnt]# cd mfsmeta/
[root@localhost mfsmeta]# ls
sustained trash
[root@localhost mfsmeta]# cd trash/
[root@localhost trash]# find -name passwd
./004/00000004|dir1|passwd 寻找文件
[root@localhost trash]# mv ./004/00000004|dir1|passwd undel/
[root@localhost dir1]# pwd
/mnt/mfs/dir1
[root@localhost dir1]# ls
bigfile passwd 又恢复了文件
