msf 使用心得

Posted 2020-10-11 划得戳

CentOS的安装方法：

To install MooseFS from officially supported repository on EL7, follow the steps below:

Add the key:

# curl "http://ppa.moosefs.com/RPM-GPG-KEY-MooseFS" > /etc/pki/rpm-gpg/RPM-GPG-KEY-MooseFS

Add an appropriate repository entry:

# curl "http://ppa.moosefs.com/MooseFS-3-el7.repo" > /etc/yum.repos.d/MooseFS.repo

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.rpm

vim /etc/hosts    #修改/etc/hosts地址解析文件

172.25.21.1 mfsmaster server1

mfsmaster 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

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.rpm

vim /etc/hosts    #修改/etc/hosts地址解析文件

172.25.21.1 mfsmaster server1

mkdir /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？
