CentOS的安装方法：
To install MooseFS from officially supported repository on EL7, follow the steps below:
Add the key:
Add an appropriate repository entry:
then install appropriate MooseFS components:
- For Master Servers:
# yum install moosefs-master moosefs-cgi moosefs-cgiserv moosefs-cli
- For Chunkservers:
# yum install moosefs-chunkserver
- For Metaloggers:
# yum install moosefs-metalogger
- For Clients:
# yum install moosefs-client
Note: If you like to install MooseFS on EL6 distributions, just change MooseFS-3-el7.repo in repository URL to MooseFS-3-el6.repo
元数据服务器 Master server 安装
需要下载的源码包及依赖包：
moosefs-3.0.97.tar.gz
libpcap-1.4.0-1.el6.rft.x86_64.rpm
libpcap-devel-1.4.0-1.el6.rft.x86_64.rpm
yum install -y gcc make rpm-build fuse-devel zlib-devel
yum install -y libpcap-1.4.0-1.el6.rft.x86_64.rpm libpcap-devel-1.4.0-1.el6.rft.x86_64.rpm
rpmbuild -tb moosefs-3.0.97.tar.gz #将源码包编译成rpm包
cd /root/rpmbuild/RPMS/x86_64 #便以后rpm包存放地址
rpm -ivh moosefs-cgi-3.0.97-1.x86_64.rpm moosefs-cgiserv-3.0.97-1.x86_64.rpm moosefs-cli-3.0.97-1.x86_64.rpm moosefs-master-3.0.97-1.x86_64.rpmvim /etc/hosts #修改/etc/hosts地址解析文件
172.25.21.1 mfsmaster server1mfsmaster start #启动master server
mfscgiserv #启动CGI监控服务netstat -anlpt #可以看到9419，9420，9421，9425 端口

tcp 0 0 ::1:25 :::* LISTEN 999/master 在浏览器地址栏输入http://172.25.21.1:9425即可查看 master的运行情况
同样的server2也可以访问它的9425端口
存储服务器 Chunk servers 安装
yum install -y moosefs-chunkserver-3.0.97-1.x86_64.rpmvim /etc/hosts #修改/etc/hosts地址解析文件
172.25.21.1 mfsmaster server1mkdir /mnt/chunk1
chown mfs.mfs /mnt/chunk1/vim /etc/mfs/mfshdd.cfg
/mnt/chunk1每个Chunk servers 端创建的目录不同，要做相应修改
mfschunkserver start现在再通过浏览器访问 http://172.25.21.1:9425/ 可以看见这个 MFS系统的信息
客户端 client安装
yum install -y moosefs-client-3.0.97-1.x86_64.rpm
mkdir /mnt/mfs #默认挂载点
mfsmount /mnt/mfs/查看
df -h
每台主机都为20G，可以看到两台Chunk servers的存储都挂载了过来
挂载命令 安装好客户端软件moosefs-client
然后使用
mkdir /mnt/data
mfsmount /mnt/data -H 172.20.10.8
简单测试结果：
写：time dd if=/dev/zero of=/usr/mfstest/test2/zhhtest500M bs=1024k count=500
读：time dd if=/usr/mfstest/test2/zhhtest500M of=/dev/null

总结规律：
1、读速度：ca 71M/s 写速度：ca 22M/s 9M/s （以500M计算）
2、goal的设置和读写速度的关系？
