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.

cd ..

cd /elain/apps/mfs/etc/
cp mfsmaster.cfg.dist mfsmaster.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 -H  master                    #客户端挂载 MooseFS 文件系统
