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

安装完毕。

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 -H  master                    #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
[root@client01 ~]# lsmod |grep fuse
fuse                   83057  6
