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
sudo rpm -ivh
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
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
sudo vim /etc/httpd/conf/httpd.conf
Listen 9480sudo /etc/init.d/mfsmaster restart
sudo /etc/init.d/httpd restart
访问WEB界面
:9480/mfs/
如下图所示
3. 安装配置备份服务器(仅在server2上)
sudo rpm --import
sudo rpm -ivh
sudo yum install mfs
cd /etc/mfs
sudo cp mfsmetalogger.cfg.dist mfsmetalogger.cfg
sudo vim /etc/mfsmetalogger.cfg
MASTER_HOST = 10.197.29.251sudo /etc/init.d/mfsmetalogger restart
4. 安装配置数据节点(在server1-3上)
sudo rpm --import
sudo rpm -ivh
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
MASTER_HOST = 10.197.29.251sudo vim mfshdd.cfg
/mnt/mfschunks1 /mnt/mfschunks2sudo 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
:9480/cgi-bin/mfs/mfs.cgi?sections=CS
5. 安装配置客户端(在server2-3上)
sudo rpm --import
sudo rpm -ivh
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
mfsmaster accepted connection with parameters: read-write,restricted_ip ; root mapped to root:rootdf -h | grep mfs
10.197.29.251:9421 25G 0 25G 0% /mnt/mfs6. 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
server2.txt
