mfs on ubuntu

            网上有很多 田逸老师的文章我就不多说些什么了.

            我说下在ubuntu 上安装过程！

 

元数据服务器    ：MDT  192.168.6.132

数据存储服务器：MDS   192.168.6.133

客户端                 ：client   192.168.6.134

客户端                 ：client2   192.168.6.135

 

客户端通过fuse内核接口挂载元数据服务器，真实数据存在数据存储服务器！

 

软件： [url]http://www.moosefs.com/files/mfs-1.5.12.tar.gz[/url]   

需要库文件：libfuse-dev

 

1.安装元数据服务器    MDT  192.168.6.132

shell $> apt-get install  libfuse-dev

shell $> tar zxvf mfs-1.5.12.tar.gz

shell $> cd mfs-1.5.12

shell $> useradd mfs

shell $> ./configure --prefix=/usr/local/mfs --disable-mfsmount  --disable-mfschunkserver --enable-mfsmaster --with-default-user=mfs --with-default-group=mfs

shell $> make

shell $> make install

shell $> cd /usr/local/mfs

shell $> ls

etc  sbin  share  var

shell $> cd etc

shell $>  vim mfsmaster.cfg

#去掉所有注释 

WORKING_USER = mfs
 WORKING_GROUP = mfs

 LOCK_FILE = /var/run/mfs/mfsmaster.pid

 CSSERV_LISTEN_PORT = 9422

 CSSERV_TIMEOUT = 60

 CSTOCS_TIMEOUT = 60

 HDD_CONF_FILENAME = /usr/local/mfs/etc/mfshdd.cfg
shell $> vim mfshdd.cfg

/mnt/data

shell $> mkdir -p /mnt/data

shell $> chown mfs.mfs /mnt/data

shell $> mkdir -p /var/run/mfs

shell $> chown mfs.mfs /var/run/mfs

shell $> /usr/local/mfs/sbin/mfschunkserver start

shell $> netstat -ant

3.安装客户端  client  192.168.6.134

shell $> apt-get install  libfuse-dev

shell $> tar zxvf mfs-1.5.12.tar.gz

shell $> cd mfs-1.5.12

bin  etc  share

shell $> bin/mfsmount --help

mfsmount v. 1.5.12
usage: ./mfsmount [-r][-m][-c] [-v 0..2] [-h master host] [-p master port] [-l path] [-w mount point]

4.安装客户端2   client2 192.168.6.135

shell $> apt-get install  libfuse-dev

shell $> tar zxvf mfs-1.5.12.tar.gz

shell $> cd mfs-1.5.12

shell $> make

shell $> make install

shell $> cd /usr/local/mfs

shell $> ls

bin  etc  share

shell $> mkdir -p /mnt/mfs

shell $> bin/mfsmount -h 192.168.6.132    ###其他参数不用，使用默认！

shell $> mount

/dev/sda1 on / type ext3 (rw,relatime,errors=remount-ro)

MFS on /mnt/mfs type fuse (rw,allow_other,default_permissions)

5.测试客户端

shell $> cd /mnt/mfs

shell $> ls

aaa

####能看到数据！！！

shell $> rm  aaa

#### 切换到 客户端1   client   192.168.6.134  看一下

shell $> ls

 

###被删掉了！！！

shell $> umount /mnt/mfs

###卸载mfs文件系统

 

 

OK 安装完毕~~随后在写 数据恢复等~~
