摘要

分布式文件系统（Distributed File System）是指文件系统管理的物理存储资源不一定直接连接在本地节点上，而是通过计算机网络与节点相连，也就是集群文件系统，可以支持大数量的节点以及PB级的数量存储。

一、基础知识

分布式存储系统的特性：

可扩展：分布式存储系统可以扩展到几百台至几千台的集群规模，且随着集群规模的增长，系统整体性能表现为线性增长

低成本：分布式存储系统的自动容错、自动负载均衡机制使其可以构建在普通PC机之上；另外，线性扩展能力也使得增加、减少机器非常方便，可以实现自动运维

高性能：无论是针对整个集群还是单台服务器，都要求分布式系统具备高性能

易用：分布式存储系统需要能够提供易用的对外接口；另外，也要求具备完善的监控、运维工具，并能方便的与其他系统集成，如从Hadoop云计算系统导入数据

MogileFS的特性：

工作于应用层：无需特殊的核心组件

无单点：三大组件(tracker，mogstore，database)皆可实现高可用

自动文件复制：复制的最小单位不是文件，而是class；基于不同的class，文件可以被自动的复制到多个有足够存储空间的存储节点上

传输中立，无特殊协议：可以通过NFS或HTTP协议进行通信

简单的命名空间：文件通过一个给定的key来确定，是一个全局的命名空间；没有目录，基于域实现文件隔离

不共享数据：无需通过昂贵的SAN来共享磁盘，每个存储节点只需维护自己所属的存储设备(device)即可

二、实验过程

1、环境介绍

配置store1 store2 SSH互相时间同步主机名互解

[root@Legion100 /etc/mogilefs]#

4、配置存储节点store2

[root@Legion101 ~]# cd /tmp
[root@Legion100 /tmp]# yum install *.rpm perl-IO-AIO perl-BSD-Resource \
perl-DBD-MySQL perl-Danga-Socket perl-IO-stringy \

[root@Legion101 /etc/mogilefs]#

5、给sotre1 和 sotre2 添加节点

[root@Legion100 ~]# mogadm --trackers=172.16.6.101:7001 host add 172.16.6.101 --ip=172.16.6.101 --status=alive
[root@Legion100 ~]# mogadm --trackers=172.16.6.101:7001 host list
172.16.6.101 [1]: alive
  IP:       172.16.6.101:7500

[root@Legion100 ~]#

[root@Legion101 /etc/mogilefs]# mogadm --trackers=172.16.6.100:7001 host add 172.16.6.100 --ip=172.16.6.100 --status=alive
[root@Legion101 /etc/mogilefs]# mogadm --trackers=172.16.6.100:7001 host list
172.16.6.101 [1]: alive
  IP:       172.16.6.101:7500

172.16.6.100 [2]: alive
  IP:       172.16.6.100:7500

[root@Legion101 /etc/mogilefs]#

6、添加设备

[root@Legion101 /etc/mogilefs]# mogadm --trackers=172.16.6.100:7001 device add 172.16.6.100 1
[root@Legion101 /etc/mogilefs]# mogadm --trackers=172.16.6.100:7001 device list
172.16.6.101 [1]: alive
                    used(G)    free(G)   total(G)  weight(%)

172.16.6.100 [2]: alive
                    used(G)    free(G)   total(G)  weight(%)
   dev2:   alive      0.000      0.000      0.000        100

[root@Legion101 /etc/mogilefs]#

[root@Legion100 ~]# mogadm --trackers=172.16.6.101:7001 device add 172.16.6.101 1
[root@Legion100 ~]# mogadm --trackers=172.16.6.101:7001 device list
172.16.6.101 [1]: alive
                    used(G)    free(G)   total(G)  weight(%)
   dev1:   alive      0.010      4.536      4.546        100

172.16.6.100 [2]: alive
                    used(G)    free(G)   total(G)  weight(%)
   dev2:   alive      0.000      0.000      0.000        100

[root@Legion100 ~]#

添加设备时所使用的设备ID号必须要/data/dev#中的编号一致

7、建立区域

[root@Legion100 /etc/mogilefs]# mogadm --trackers=172.16.6.101:7001 domain add images
[root@Legion100 /etc/mogilefs]# mogadm --trackers=172.16.6.101:7001 domain add text

-------------------- -------------------- ------------- ------------ -------
 images               default                   2        MultipleHosts() NONE   

 text                 default                   2        MultipleHosts() NONE   

[root@Legion100 /etc/mogilefs]#

8、在每一个区域中建立class

[root@Legion100 /etc/mogilefs]# mogadm --trackers=172.16.6.101:7001 class add images class1 --mindevcount=2
[root@Legion100 /etc/mogilefs]# mogadm --trackers=172.16.6.101:7001 class add images class2 --mindevcount=2
[root@Legion100 /etc/mogilefs]# mogadm --trackers=172.16.6.101:7001 class add text class1 --mindevcount=2
[root@Legion100 /etc/mogilefs]# mogadm --trackers=172.16.6.101:7001 class add text class2 --mindevcount=2
[root@Legion100 /etc/mogilefs]# mogadm --trackers=172.16.6.101:7001 class list
 domain               class                mindevcount   replpolicy   hashtype
-------------------- -------------------- ------------- ------------ -------
 images               class1                    2        MultipleHosts() NONE
 images               class2                    2        MultipleHosts() NONE
 images               default                   2        MultipleHosts() NONE   

 text                 class1                    2        MultipleHosts() NONE
 text                 class2                    2        MultipleHosts() NONE
 text                 default                   2        MultipleHosts() NONE   

[root@Legion100 /etc/mogilefs]#

domain :区域
class:复制文件的最小单位（最大为64M,如果一个单文件超出此大小将拆分为多个class存储）
mindevcount：最小复制文件的份数
replpolicy ：复制份数
hashtype：采用的hash的类型

9、上传文件进行测试

1)、图片区域

[root@Legion100 ~]# mogupload --trackers=172.16.6.101:7001 --domain=images --key='/images/2k.png' \

[root@Legion100 ~]# mogupload --trackers=172.16.6.101:7001 --domain=text --key='/text/hosts.html' --file='/etc/hosts'

[root@Legion102 /usr/local/nginx/conf]# cd
[root@Legion102 ~]# service nginx start
正在启动 nginx：                                           [确定]

12、测试Nginx+MogileFS
