**server1：**  
1.安装master和管理的web图形界面

[root@server1 ~]# yum install moosefs-cli-3.0.103-1.rhsystemd.x86_64.rpm moosefs-cgiserv-3.0.103-1.rhsystemd.x86_64.rpm moosefs-cgi-3.0.103-1.rhsystemd.x86_64.rpm moosefs-master-3.0.103-1.rhsystemd.x86_64.rpm -y
    [root@server1 ~]# cd /etc/mfs/
    [root@server1 mfs]# ls
    mfsexports.cfg         mfsmaster.cfg         mfstopology.cfg
    mfsexports.cfg.sample  mfsmaster.cfg.sample  mfstopology.cfg.sample
    [root@server1 mfs]# vim mfsmaster.cfg		##主配置文件

2.主节点写入解析

[root@server1 mfs]# vim /etc/hosts

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 1]  
3.开启服务并查看端口

[root@server1 mfs]# systemctl start moosefs-master
    [root@server1 mfs]# netstat -antlp

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 2]

> 端口介绍：  
> 9419：metalogger监听的端口地址，和原数据日志相结合，定期和master端同步数据  
> 9420：用于和chunkserver连接的端口地址，通信节点  
> 9421：用于客户端对外连接的点口地址

4.打开cgi图形化管理工具

[root@server1 mfs]# systemctl start moosefs-cgiserv.service
    [root@server1 mfs]# netstat -antlp

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 3]

浏览器输入：  
http://172.25.16.1:9425/mfs.cgi  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 4]

**server2部署：**  
1.安装chunkserver

[root@server2 ~]# rpm -ivh moosefs-chunkserver-3.0.103-1.rhsystemd.x86_64.rpm

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 5]

2.添加解析

[root@server2 ~]# vim /etc/hosts

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 6]  
3.给server2添加一块硬盘  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 7]

[root@server2 ~]# fdisk -l

![在这里插入图片描述][20190817214340528.png]

4.创建分区并格式化  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 8]![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 9]  
空间全部都给一块分区

格式化  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 10]

5.挂载

[root@server2 ~]# mkdir /mnt/chunk1
    [root@server2 ~]# mount /dev/vdb1 /mnt/chunk1/
    [root@server2 ~]# df

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 11]  
6.编辑chunkserver的相应配置文件添加共享data的挂载路径

[root@server2 ~]# cd /etc/mfs
    [root@server2 mfs]# ls
    mfschunkserver.cfg  mfschunkserver.cfg.sample  mfshdd.cfg  mfshdd.cfg.sample
    [root@server2 mfs]# vim mfshdd.cfg

![在这里插入图片描述][20190817215247169.png]  
7.修改挂载目录的用户和所属组

[root@server2 chunk1]# chown mfs.mfs /mnt/chunk1/

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 12]  
8.查看开启的端口

[root@server2 chunk1]# systemctl start moosefs-chunkserver
    [root@server2 chunk1]# netstat -antlp

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 13]

刷新浏览器：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 14]  
server3同server2一样操作

[root@server3 ~]# yum install -y moosefs-chunkserver-3.0.103-1.rhsystemd.x86_64.rpm
    [root@server3 ~]# vim /etc/hosts
    [root@server3 ~]# mkdir /mnt/chunk2
    [root@server3 ~]# chown mfs.mfs /mnt/chunk2/
    [root@server3 ~]# vim /etc/mfs/mfshdd.cfg
    [root@server3 ~]# systemctl start moosefs-chunkserver
    [root@server3 ~]# netstat -antlp

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 15]

刷新浏览器：  
server3已添加  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 16]

**客户端的搭建（真机）**  
1.安装client服务

[root@foundation60 3.0.103]# rpm -ivh moosefs-client-3.0.103-1.rhsystemd.x86_64.rpm

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 17]  
2.添加解析

[root@foundation60 3.0.103]# vim /etc/hosts

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 18]  
3.创建真机挂载的数据的目录并且编辑配置文件添加挂载目录

[root@foundation60 3.0.103]# mkdir /mnt/mfs
    [root@foundation60 3.0.103]# vim /etc/mfs/mfsmount.cfg

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 19]

4.客户端挂载

[root@foundation60 mfs]# mfsmount

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 20]  
5.挂载客户端下创建目录并且查看相应信息

[root@foundation60 ~]# mfsmount 
    [root@foundation60 ~]# df
    [root@foundation60 ~]# cd /mnt/mfs/
    [root@foundation60 mfs]# ls
    [root@foundation60 mfs]# mkdir dir1
    [root@foundation60 mfs]# mkdir dir2
    [root@foundation60 mfs]# mfsgetgoal dir1/
    dir1/: 2
    [root@foundation60 mfs]# mfsgetgoal dir2
    dir2/: 2			##默认会分别在俩个chunkserver上备份数据

可能出现的错误：

dir1/: realpath error on (/mnt/mfs/dir1): ENOENT (No such file or directory)  
![在这里插入图片描述][20190817222859504.png]

返回/目录从新操作一遍

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 21]

6.客户端备份测试：

*  指定挂载目录下的dir1的目录中文件备份为1

![在这里插入图片描述][20190818124054176.png]

*  dir1和dir2目录下存储信息

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 22]

*  关闭server2的chunkserver服务

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 23]

*  dir1目录下只备份一份在server2上，所以关闭服务会丢失数据

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 24]

7.客户端离散数据存储

开启server2的chunkserver服务  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 25]

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDg4OTYxNg_size_16_color_FFFFFF_t_70 26]

默认chunkserver对数据的备份是按块来备份的，每一块备份50M

**mosefs-master的服务开启及关闭：**
