CentOS上安装MooseFS分布式文件系统2种方式

方法一

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.

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

MooseFS 命令的使用方法及参考文档：

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

方法二

环境介绍：
OS: CentOS 6.3 x86_64
server1 - mfsmaster & mfschunkserver
server2 - mfsmetalogger & mfschunkserver & mfsclient
server3 - mfschunkserver

1. 什么是MooseFS
MooseFS是一个具有容错能力的分布式文件系统，支持挂载(通过FUSE)和与本地文件系统相同的操作。

MooseFS具有以下几个角色：
主服务器：Managing Server(master server)
数据节点：Data server(chunk servers)
备份服务器：Metadata backup servers(metalogger servers)
客户端：Client computers that access(mount) the files in MooseFS

2. 安装配置主服务器(仅在server1上)
sudo rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
sudo rpm -ivh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
sudo yum install mfs

cd /etc/mfs
sudo cp mfsmaster.cfg.dist mfsmaster.cfg
sudo cp mfsmetalogger.cfg.dist mfsmetalogger.cfg
sudo cp mfsexports.cfg.dist mfsexports.cfg

修改主服务器的地址，比如10.197.29.251
sudo vim /etc/mfsmetalogger.cfg

1 MASTER_HOST = 10.197.29.251
初始化数据文件
cd /var/mfs
sudo cp metadata.mfs.empty metadata.mfs

安装WEB界面支持
sudo yum install mfs-cgi httpd
sudo vim /var/www/html/mfs/index.html

1 document.location.href="/cgi-bin/mfs/mfs.cgi"
sudo vim /etc/httpd/conf/httpd.conf

1 Listen 9480

sudo /etc/init.d/mfsmaster restart
sudo /etc/init.d/httpd restart

访问WEB界面

http://server1:9480/mfs/

如下图所示

3. 安装配置备份服务器(仅在server2上)
sudo rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
sudo rpm -ivh http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm

sudo yum install mfs

cd /etc/mfs
sudo cp mfsmetalogger.cfg.dist mfsmetalogger.cfg

sudo vim /etc/mfsmetalogger.cfg

1 MASTER_HOST = 10.197.29.251
sudo /etc/init.d/mfsmetalogger restart

4. 安装配置数据节点(在server1-3上)
sudo rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
sudo rpm -ivh http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm

sudo yum install mfs

cd /etc/mfs
sudo cp mfschunkserver.cfg.dist mfschunkserver.cfg
sudo cp mfshdd.cfg.dist mfshdd.cfg

sudo vim mfschunkserver.cfg

1 MASTER_HOST = 10.197.29.251
sudo vim mfshdd.cfg

1 /mnt/mfschunks1

2 /mnt/mfschunks2
sudo mkdir /mnt/mfschunks1 /mnt/mfschunks2
sudo chown -R daemon:daemon /mnt/mfschunks*

sudo /etc/init.d/mfschunkserver restart

访问WEB界面，检查新增的chunkserver

http://server1:9480/cgi-bin/mfs/mfs.cgi?sections=CS

5. 安装配置客户端(在server2-3上)
sudo rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
sudo rpm -ivh http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm

sudo yum install mfs-client

sudo mkdir -p /mnt/mfsmount
sudo chown -R daemon:daemon /mnt/mfsmount

sudo mfsmount /mnt/mfsmount -H 10.197.29.251

1 mfsmaster accepted connection with parameters: read-write,restricted_ip ; root mapped to root:root
df -h | grep mfs

1 10.197.29.251:9421 25G 0 25G 0% /mnt/mfs
6. 测试MooseFS
在server2上创建文件server2.txt：
cd /mnt/mfsmount
echo "I am from server2" > server2.txt

在server3上检查文件是否存在：
cd /mnt/mfsmount

ls

1 server2.txt
