一、简介

  MogileFS是一个开源的分布式文件存储系统,由LiveJournal旗下的Danga Interactive公司开发;它主要由三部分组成,第一部分是server端,server端主要包括mogilefsd和mogstored两个应用程序。mogilefsd实现的是tracker,它通过数据库来保存元数据信息,包括站点domain、class、host等;mogstored是存储节点(store node),它其实是个WebDAV服务,默认监听在7500端口,接受客户端的文件存储请求。在MogileFS安装完后,要运行mogadm工具将所有的store node注册到mogilefsd的数据库里,mogilefsd会对这些节点进行管理和监控。第二部是mogilefs的utils,这部分主要是一些工具,比如mogadm、mogupload、mogfileinfo 等等;第三部分是客户端API,mogilefs支持众多编程语言的客户端API接口,使用对应的客户端API接口,我们可以编写mogilefs的客户端,从而实现来管理mogilefs上的文件;

  二、Mogilefs架构图

  提示:tracker的主要作用是代理前端用户的请求到数据库查询相关文件的元信息,同时它还要监控注册到trancker的storagenode的健康状态,一旦后端storage挂掉,它会立刻把对应的storage节点上的device从集群的中删除,上线时在加入到集群;客户端通过向tracker发送请求文件的信息,tracker通过去数据库中找到对应的文件所在storage节点的ip地址、端口、设备id以及文件fid,然后通过http链接的形式从tracker返回给客户端,客户端拿到这trancker的返回的文件地址,然后在去对应的storage请求文件,从而在客户端就访问到对应的文件内容信息;客户端和trancker,storage之间通信都是http协议,从本质上讲storage就是一个web服务器;所以对于客户端我们可以使用web服务器的反向代理,也可以是调用mogilefsAPI写的客户端程序;

  三、Mogilefs安装部署

  环境说明

名称 角色 ip地址 端口
node01 tracker+mysql+storage 192.168.0.41 7001/7500/7501/3306
node02 tracker+storage 192.168.0.42 7001/7500/7501
node03 storage 192.168.0.43 7500/7501

  各server时间同步

  提示:如果有必要,可以配置各节点用hosts文件解析;

  配置mariadb忽略名称解析

  设置mariadb开机自动启动,并启动mariadb

  添加用于mogilefs访问数据库的账号

  初始化数据库

  提示:如果不想让mogdbsetup在数据库中创建一个任何地址都可访问的mogilefs的用户,在最后的选项中使用n即可,然后在重复执行上述命令即可;如果不想交互式输入y,也可以直接在命令后面用--yes;

  验证:在数据库中查看对应的库是否都已创建,对应库中是否都有表?

  到此数据库就准备好了

  配置mogilefsd连接数据库

  提示:我们只需要修改红框中的内容即可;db_dsn用于指定连接数据库的驱动,以及数据库库名和主机地址;db_user用于指定连接数据库所使用的用户,db_pass用于指定连接数据库的密码;listen用于指定mogilefsd监听的ip地址和端口;后面的配置就是和启动的进程数量的配置,这个可以根据业务的规模来设置;

  启动mogilefsd

  提示:在centos7上启动mogilefsd时,会报错,我们可以不用管这个错误,实际上mogilefsd是启动成功的,只要看到对应的端口和进程起来,表示mogilefsd启动就没有问题;

  配置node01上的mogstored

[root@node01 ~]# cat /etc/mogilefs/mogstored.conf
maxconns = 10000
httplisten = 0.0.0.0:7500
mgmtlisten = 0.0.0.0:7501
docroot = /data/mogilefs
[root@node01 ~]# mkdir /data/mogilefs/ -pv
mkdir: created directory ‘/data’
mkdir: created directory ‘/data/mogilefs/’
[root@node01 ~]# chown -R mogilefs.mogilefs /data/mogilefs/
[root@node01 ~]# ll -d /data/mogilefs/
drwxr-xr-x 2 mogilefs mogilefs 6 Sep 16 13:37 /data/mogilefs/
[root@node01 ~]#

  启动mogstored

  提示:在centos7上启动mogstored也会同启动mogilefsd一样报错,这个主要是因为systemd的缘故,在centos6不会报错;到此,node01上的mariadb、mogilefsd和mogstored都已经安装配置好了;

  复制安装包到node02和node03

  把node01上的mogilefsd的配置文件复制到node02上,然后启动mogilefsd

  把node01上的mogstored配置文件复制到node02上,然后在node02上创建对应的目录并修改属主和属组为mogilefs,然后启动mogstored

  到此node02上的mogilefsd和mogstored就安装配置启动好了;

  在node03上安装配置mogstored

[root@node03 ~]#

  复制node01上的mogstored配置文件到node03上,然后在node03上创建对应的目录并修改属主和属组为mogilefs,然后启动mogstored

  提示:在node03上没有安装mogilefs-server这个包,所以在对应系统上没有mogilefs这个账号,我们需要手动创建这个账号;

  启动mogstored

  到此三个节点的环境配置,以及服务都已经正常启动了;

  四、使用mogadm管理mogilefs

  把三个storage节点注册到tracker上

  提示:如果集群各节点没有做hosts主机名解析,那么对应的的节点就需要写清楚ip地址即可,如果端口不是7500,我们还需要用--port去指定端口;

  检查集群

  提示:在tracker节点监听在本机所有地址的7001,执行上述命令不需要加--trackers选项来指明tracker是谁,它默认会去找本机的7001;否则执行上述命令需要加上--trackers来指定tracer的地址和端口;

  在非tracker节点执行检查集群的命令

  创建devices

  分别在3个mogstored节点的docroot说指定的目录下创建以dev+数字的目录,并将属主和属组修改成mogilefs

[root@node03 ~]# mkdir /data/mogilefs/dev3
[root@node03 ~]# chown -R mogilefs.mogilefs /data/mogilefs/dev3
[root@node03 ~]# ll -d /data/mogilefs/dev3
drwxr-xr-x 3 mogilefs mogilefs 37 Sep 16 21:02 /data/mogilefs/dev3
[root@node03 ~]#

  添加device

  查看device

  提示:如果在指定节点的docroot所指定的目录下没有创建dev+设备编号的目录,上面是看不到对应设备的空间大小的;

  创建domain

  创建class

  好了,到此我们就可以上传文件了

  上传文件,把/etc/passwd上传到files域中,使用html class

  提示:mogupload这个工具是mogilefs的一个上传文件的工具,其中--domain用于指定域,就是把文件放到那个名称空间中;--class用于指定使用那个class策略来同步文件,默认不指定使用default;--key用于指定客户端访问文件的路径;--file用于指定要上传的文件路径;

  查看上传文件的信息

  提示:查看上传文件的信息需要用mogfileinfo这个工具,我们只需要指定trancker,domain以及文件的key就可以看到,该文件的class,devcount,domain,fid,key,length,以及访问http地址;这里需要说明一下,我们刚才在创建files域中的html这个class 我们指定了mindevcount=3,表示只要使用这个class上传文件,文件至少有3个副本;而我们现在看到的只有一个,这是因为在centos7上,Sys-syscall这个包的版本过高,导致mogilefs异常;

  降级Sys-Syscall,解决centos7上安装mogilefs 后端mogstored 同步问题

  安装perl编译环境

[root@node01 ~]#

  提示:在mogstored节点上都要安装好perl环境依赖包;然后按照下面的步骤重新编译安装Sys-Syscall;然后重启mogstored即可生效;

  下载低版本的Sys-Syscall源码包,并解压,进入到源码目录

  编译安装Sys-Syscall

  验证

  重启mogstored,mogilefsd

  提示:所有storage节点都有重新编译安装Sys-Syscall,然后重启mogstored;对应的tracker节点也需要重启mogilefsd;

  上传文件看看对应的副本数量是否还是只有一个?

  提示:可以看到对应的devcount和我们之前指定的class上的mindevcount就一样了;

  验证:访问指定上述任一一个地址,看看访问到的文件内容是否是我们上传到文件内容?

  提示:可以看到我们上传到文件内容在tracker给我们返回的地址上能够访问到,并且里面的内容也是一样的;

  验证:停掉node02上的mogstored,看看对应的tracker是否能够及时发现对应的storage不在线了呢?

  提示:可以看到当node02上的mogstored挂掉以后,在检查集群,tracker就能及时的发现对应的设备不在线了,这个有点类似nginx对后端web服务器做健康状态监测的感觉;也就说tracker在监视着注册在tracker上的storage节点;

  到此,mogilefs在centos7上的安装部署,以及使用mogadm工具管理集群就完成了,对于mogilefs通常我们上传文件是通过业务程序调用api实现,mogupload只是一个测试工具;对于查看文件,通常用户也不会使用mogfieinfo返回的链接去查看文件,通常会使用一个web反向代理(nginx)去代理用户的访问;比如用户要查看/images/test.jpg,而在tracker返回的对应资源的链接中,一定不是/images/test.jpg,这个时候我们就需要用到web反向代理,让其反向代理能够帮助我们去tracker取到对应uri的资源链接,从而帮助我们去storage节点获取到对应的文件,然后再返回给用户;最后还是建议,如果用到mogilefs,最好跑在centos6上,centos7系统环境较高,有些依赖可能成问题;在centos6上,我测试过,完全没有上述的问题;我们只需要安装perl-IO-AIO这一个依赖包就可以解决mogstored启动问题;centos6上需要用到的rpm包可以去我的网盘下载http://www.qiuhom.com/d/47e8f7ac56a445f1bfc6/
