分布式文件系统MooseFS的部署安装
概述：MooseFS是一种分布式文件系统，MooseFS文件系统结构包括以下四种角色：
1 管理服务器managing server (master)
2 元数据日志服务器Metalogger server（Metalogger）
3 数据存储服务器data servers (chunkservers)
4 客户机挂载使用client computers 各种角色作用:
1 管理服务器:负责各个数据存储服务器的管理,文件读写调度,文件空间回收以及恢复.多节点拷贝
2 元数据日志服务器: 负责备份master服务器的变化日志文件，文件类型为changelog_ml.*.mfs，以便于在master server出问题的时候接替其进行工作
3 数据存储服务器:负责连接管理服务器,听从管理服务器调度,提供存储空间，并为客户提供数据传输.
4 客户端: 通过fuse内核接口挂接远程管理服务器上所管理的数据存储服务器,.看起来共享的文件系统和本地unix文件系统使用一样的效果.

master 安装(10.0.0.141)
mkdir -p /root/tools/moosefs/
cd /root/tools/moosefs/
/usr/sbin/groupadd -g 660 mfs
/usr/sbin/useradd -g mfs mfs -u 660 -s /sbin/nologin
wget http://www.moosefs.org/tl_files/mfscode/mfs-1.6.20-2.tar.gz
tar zxvf mfs-1.6.20-2.tar.gz
cd mfs-1.6.20-2
./configure \
--prefix=/elain/apps/mfs \
--sysconfdir=/elain/apps/mfs/etc \
--localstatedir=/elain/apps/mfs/lib \
--with-default-user=mfs \
--with-default-group=mfs \
--disable-mfschunkserver \
--disable-mfsmount
make && make install
cd ..
cd /elain/apps/mfs/etc/
cp mfsmaster.cfg.dist mfsmaster.cfg
cp mfsmetalogger.cfg.dist mfsmetalogger.cfg
cp mfsexports.cfg.dist mfsexports.cfg
vi mfsexports.cfg
10.0.0.0/24 / rw,alldirs,maproot=0
cd /elain/apps/mfs/lib/mfs
cp metadata.mfs.empty metadata.mfs
vi /etc/hosts
10.0.0.141 mfsmaster
运行mfs服务
/elain/apps/mfs/sbin/mfsmaster start
master metaloggers module: listen on *:9419
master chunkservers module: listen on *:9420
main master server module: listen on *:9421
运行监控平台
/elain/apps/mfs/sbin/mfscgiserv
starting simple cgi server (host: any , port: 9425 , rootpath: /elain/apps/mfs/share/mfscgi)
这时，可通过浏览器访问：http://10.0.0.141:9425/查看 master 的运行情况

停止 MooseFS
为了安全停止 MooseFS 集群,建议执行如下的步骤:
umount -l /mnt/mfs #客户端卸载MooseFS 文件系统
/elain/apps/mfs/sbin/mfschunkserver stop #停止 chunk server 进程
/elain/apps/mfs/sbin/mfsmetalogger stop #停止 metalogger 进程
/elain/apps/mfs/sbin/mfsmaster stop #停止主控 master server 进程
安全的启动MooseFS集群
/elain/apps/mfs/sbin/mfsmaster start #启动 master 进程
/elain/apps/mfs/sbin/mfschunkserver start #启动 chunkserver 进程
/elain/apps/mfs/sbin/mfsmetalogger start #启动 metalogger 进程
/elain/apps/mfs/bin/mfsmount /mnt/mfs -Hmaster #客户端挂载 MooseFS 文件系统

FAQ:
/elain/apps/mfs/bin/mfsmount /elain/data/htdocs/elain/upload -H master
mfsmaster accepted connection with parameters: read-write,restricted_ip ; root mapped to root:root
fuse: device not found, try 'modprobe fuse' first
error in fuse_mount
答：modprobe fuse
# lsmod |grep fuse
