Master 1 client 6 chunkserver 2 5
master端：
mv moosefs-3.0.80-1.tar.gz moosefs-3.0.80.tar.gz
Rpmbuild -tb moosefs-3.0.80.tar.gz
缺少依赖性：yum install libpcap-1.4.0-4.20130826git2dbcaa1.el6.x86_64.rpm -y
yum install libpcap-devel-1.4.0-4.20130826git2dbcaa1.el6.x86_64.rpm -y
cd ~/rpmbuild/RPMS/x86_64
yum install -y moosefs-cgi-3.0.80-1.x86_64.rpm
moosefs-cgiserv-3.0.80-1.x86_64.rpm
moosefs-master-3.0.80-1.x86_64.rpm
moosefs-cli-3.0.80-1.x86_64.rpm
moosefs-netdump-3.0.80-1.x86_64.rpm
添加解析 在master地址后添加 mfsmaster
执行 mfsmaster mfscgiserv
访问http://172.25.60.1:9425
Server 2 5
moosefs-chunkserver-3.0.80-1.x86_64.rpm
vim /etc/mfs/mfshhd.cfg 最下一行添加：/mnt/chunk1 2 chown mfs.mfs /mnt/chunk 1 2
在hosts里添加master端的解析:mfsmaster
开启服务 mfschunkserver
server6 client端
安装moosefs-client
Vim /etc/mfs/mfsmount.cfg在最后一行添加：/mnt/mfs
在hosts里添加server 端解析 mfsmaster
Mkdir /mnt/mfs
执行mfsmountdf查看挂载
测试：
cd /mnt/mfs mkdir dir1 dir2
Mfssetgoal -r 1 dir1 mfssetgoal -r 2 dir2 #####dir1里只存储一份 dir2里存储两份
Mfsgetgoal dir1 查看更改
数据误删除恢复：
假如删除了 dir1/passwd
建立目录 /mnt/mfsmeta
Mfsmount -m /mnt/mfsmeta
Cd /mfsmeta/trashfind -type f
Mv ./004/00000004/|dir1\|passwdundel
解决单点故障：
采用pacemaker+iscsi
先做iscsi
将/var/log/mfs/* 拷贝到此块设备中 并更改为mfs.mfs
出现的错误：在第一个master上能够成功启动，但在第二个master上启动失败了，
原因：在第二个用户上没有mfs用户导致权限出现问题
安装pacemaker corosync pssh-2.3.1-4.1.x86_64.rpm crmsh-1.2.6-0.rc2.2.1.x86_64.rpm
在两个节点上Yum install pacemaker corosync
Cd /etc/corosync cp corosync.conf.example corosync.conf
同步两端的此配置文件
启动两端服务 /etc/init.d/corosync start
将mfs启动的脚本文件放入 init.d中：
#!/bin/bash
#
#Init file for the MooseFS master service
#
#chkconfig: - 92 84
#
#description: MooseFS master
#
#processname: mfsmaster
#Source function library.

为脚本文件添加执行权限并拷贝至另一节点
添加策略
关闭fence： property stonith-enabled=false
添加vip：primitive vip ocf:heartbeat:IPaddr2 params ip=172.25.60.100 cidr_netmask=32 op monitor interval=20s
添加脚本启动：primitive mfsmaster lsb:mfsd op monitor
添加挂载：
primitive mfsdata ocf:heartbeat:Filesystem params device=/dev/sdb1 directory=/var/lib/mfs fstype=ext4 op monitor interval=20s
添加组策略：group mfsgroup vip mfsdata mfsmaster
