一、MogileFS介绍
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。Danga团队开发了包括 Memcached、MogileFS、Perlbal 等多个知名的开源项目。目前使用MogileFS 的公司非常多，如日本排名先前的几个互联公司及国内的yupoo(又拍)、digg、豆瓣、1号店、大众点评、搜狗和安居客等，分别为所在的组织或公司管理着海量的图片。
MogileFS由3个部分组成：
(1) server：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。
(2) utils（工具集）：主要是MogileFS的一些管理工具，例如mogadm等。
(3) 客户端API：MogileFS的客户端API很多，例如Perl、PHP、Java、Python等，用这个模块可以编写客户端程序，实现文件的备份管理功能等。
存储主机(节点)
这个是 MogileFS 存储文件存放在这些机器上,也是 mogstored 节点,也叫 Storage Server,一台存储主要都要启动一个 mogstored 服务.扩容就是增加这些机器.
设备(device)
一个存储节点,以就是上面的主机,可以有多个 device, 就是用来存放文件的目录(例如挂载的目录),每个设备都有一个设备id,需要在 mogstored 的配置文件中的 docroot 配置的项目 指定的目录下面创建相应的设备的目录,目录名为 $docroot/dev$id,设备是不能删除的.只能将其设备的状态的值置为dead,当一个设备 dead 之后,就真的 dead了,里面的数据也无法恢复了,且这个dead了的设备的 id 也不能再用.
二、扑拓图
10.1.2.180 为tracker节点，并且首先安装mysql服务
10.1.2.200-202,总共3台，作为mogstored存储节点
三、180部署步聚
1、安装相关包

[root@logicserver mogilefs]# vim /etc/yum.repos.d/MariaDB.repo
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/5.5/centos6-amd64
gpkgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1 手动导入MariaDB的签署密钥
[root@logicserver mogilefs]# rpm --import https://yum.mariadb.org/RPM-GPG-KEY-MariaDB 开始yum安装并启动
[root@logicserver mogilefs]# yum install MariaDB-server MariaDB-client[root@logicserver mogilefs]# /etc/init.d/mysql start 3、 启动MogileFS前，设定数据库
3.1在数据前授权
MariaDB [mogilefs]> grant all on mogilefs.* to moguser@'10.1.%.%' indentified by 'mog168'; 3.2设定数据库
[root@logicserver ~]# mogdbsetup --dbhost=10.1.2.180 --dbport=3306 --dbname=mogilefs --dbrootuser=root --dbrootpass=168 --dbuser=moguser --dbpass=mog168
This will attempt to setup or upgrade your MogileFS database.
It won't destroy existing data.
Run with --help for more information. Run with --yes to shut up these prompts.
Continue? [N/y]: y

4、修改主配置文件
[root@logicserver ~]# vim /etc/mogilefs/mogilefsd.conf
# Enable daemon mode to work in background and use syslog
daemonize = 1
# Where to store the pid of the daemon (must be the same in the init script)
pidfile = /var/run/mogilefsd/mogilefsd.pid
# Database connection information
db_dsn = DBI:mysql:mogilefs:host=10.1.2.180
db_user = moguser
db_pass = mog168
# IP:PORT to listen on for mogilefs client requests
listen = 10.1.2.180:7001
# Optional, if you don't define the port above.
conf_port = 7001
# Number of query workers to start by default.
query_jobs = 10
# Number of delete workers to start by default.
delete_jobs = 1
# Number of replicate workers to start by default.
replicate_jobs = 5
# Number of reaper workers to start by default.
# (you don't usually need to increase this)
reaper_jobs = 1
# Number of fsck workers to start by default.
# (these can cause a lot of load when fsck'ing)
#fsck_jobs = 1
# Minimum amount of space to reserve in megabytes
# default: 100
# Consider setting this to be larger than the largest file you
# would normally be uploading.
#min_free_space = 200
# Number of seconds to wait for a storage node to respond.
# default: 2
# Keep this low, so busy storage nodes are quickly ignored.
#node_timeout = 2
# Number of seconds to wait to connect to a storage node.
# default: 2
# Keep this low so overloaded nodes get skipped.
#conn_timeout = 2
# Allow replication to use the secondary node get port,
# if you have apache or similar configured for GET's
#repl_use_get_port = 1 5、确保pid文件属主，属组为mogilefs
[root@logicserver ~]# ls -ld /var/run/mogilefsd
drwxr-xr-x. 2 mogilefs mogilefs 4096 10月 8 2013 /var/run/mogilefsd 6、启动mogilefsd并确定监听端口为7001
[root@logicserver ~]# /etc/init.d/mogilefsd start
Starting mogilefsd [确定][root@xenserver1 data0]# netstat -tlnp | grep 7001 四、mogstored 节点
1、200的主机，同样安装这几个rpn包
MogileFS-Server-mogstored-2.46-2.el6.noarch
MogileFS-Server-mogilefsd-2.46-2.el6.noarch
perl-MogileFS-Client-1.14-1.el6.noarch
MogileFS-Server-2.46-2.el6.noarch
MogileFS-Utils-2.19-1.el6.noarch
2、在/data0下创建数据存放位置，并把属主，属组设好
[root@xenserver1 data0]# mkdir nfs/mogdata -pv[root@xenserver1 data0]# chown -R mogilefs.mogilefs nfs/ 3、编辑配置文件
[root@xenserver1 data0]# vim /etc/mogilefs/mogstored.conf
maxconns = 10000
httplisten = 0.0.0.0:7500
mgmtlisten = 0.0.0.0:7501
docroot = /data0/nfs/mogdata 4、启动mogstored，查看监听端口
[root@xenserver1 data0]# /etc/init.d/mogstored start
Starting mogstored [确定][root@xenserver1 data0]# netstat -tlnp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

tcp 0 0 ::1:25 :::* LISTEN 1553/master
tcp 0 0 :::38585 :::* LISTEN 1245/rpc.statd 5、找不到监听端口，没起来
[root@xenserver1 data0]# su mogilefs
bash-4.1$ mog
mogadm mogdbsetup mogfetch mogfileinfo moglistfids mogrename
mogautomount mogdelete mogfiledebug mogilefsd moglistkeys mogstats
bash-4.1$ mogstored -c /etc/mogilefs/mogstored.conf
Running.
ERROR: IO::AIO not installed, so async IO not available. Refusing to run
unless you set the environment variable MOGSTORED_RUN_WITHOUT_AIO=1
6、从上面错误显示，依赖关系IO-AIO没解决好
[root@xenserver1 data0]# yum -y install perl-IO-AIO
7、安装，重新启动，查看监听端口
[root@xenserver1 data0]# /etc/init.d/mogstored start
Starting mogstored [确定]
[root@xenserver1 data0]# ss -tln | grep -E '(7500|7501)'
LISTEN 0 128 *:7500 *:*
LISTEN 0 128 *:7501 *:*
五、180主机测试
1、用mogadm
[root@logicserver ~]# mogadm -h

2、
[root@logicserver ~]# mogstats -h
Usage:
mogstats --db_dsn="DBI:mysql:mfs:host=mfshost" --db_user="mfs"
--db_pass="mfs" --verbose --stats="devices,files"
mogstats --stats="all"
mogstats [all options in ~/.mogilefs.conf]
valid stats: all, delete-queue, devices, domains, fids, files, general-queues, replication, replication-queue
3、没有添加进来，查看主机是为空的
[root@logicserver ~]# mogadm --trackers=10.1.2.180:7001 host list
3.1查看帮助添加主机
[root@logicserver ~]# mogadm --trackers=10.1.2.180:7001 host add
ERROR: Missing argument 'hostname'
Help for 'host-add' command:
mogadm host add [opts] Add a host to MogileFS.
Hostname of machine
--altip=s Alternate IP that is machine is reachable from
--altmask=s Netmask which, when matches client, uses alt IP
--getport=i Alternate HTTP port serving readonly traffic
--ip=s IP address of machine.
--port=i HTTP port of mogstored
--status=s One of {alive,down}. Default 'down'.
3.2添加主机10.1.2.200
[root@logicserver ~]# mogadm --trackers=10.1.2.180:7001 host add 10.1.2.200 --ip=10.1.2.200 --status=alive
3.3在查看主机列表
[root@logicserver ~]# mogadm --trackers=10.1.2.180:7001 host list
10.1.2.200 [1]: alive
IP: 10.1.2.200:7500
4、查看帮助和添加设备列表
4.1查看
[root@logicserver ~]# mogadm --trackers=10.1.2.180:7001 device list
10.1.2.200 [1]: alive
used(G) free(G) total(G) weight(%)
[root@logicserver ~]# mogadm --trackers=10.1.2.180:7001 device add
ERROR: Missing argument 'hostname'
Help for 'device-add' command:
mogadm device add [opts] Add a device to a host.
Numeric devid. Never reuse these.
Hostname to add a device
--status=s One of 'alive' or 'down'. Defaults to 'alive'.
4.2添加设备，ID号随便取，由于--status默认是alive，可以不指定了
[root@logicserver ~]# mogadm --trackers=10.1.2.180:7001 device add 10.1.2.200 001
4.3查看
[root@logicserver ~]# mogadm --trackers=10.1.2.180:7001 device list
10.1.2.200 [1]: alive
used(G) free(G) total(G) weight(%)
dev1: alive 0.000 0.000 0.000 100
5、创建domain为files（名称随取）
[root@logicserver ~]# mogadm --trackers=10.1.2.180:7001 domain add files
[root@logicserver ~]# mogadm --trackers=10.1.2.180:7001 domain list
domain class mindevcount replpolicy hashtype
-------------------- -------------------- ------------- ------------ -------
files default 2 MultipleHosts() NONE
六、在201上同样安装这些rpm包
1、
[root@hadoop3 MogileFS]# yum install *.rpm perl-IO-AIO -y
2、
[root@hadoop3 MogileFS]# vim /etc/mogilefs/mogstored.conf
maxconns = 10000
httplisten = 0.0.0.0:7500
mgmtlisten = 0.0.0.0:7501
docroot = /nfs/mogdata
~
3、
[root@hadoop3 MogileFS]# mkdir /nfs/mogdata -pv[root@hadoop3 MogileFS]# chown -R moigilefs.mogilefs /nfs/mogdata/
4、
[root@hadoop3 MogileFS]# service mogstored start
七、回到180的主机，把10.1.2.201 也添加进去
1、
[root@logicserver ~]# mogadm --trackers=10.1.2.180:7001 host add 10.1.2.201 --ip=10.1.2.201 --status=alive 2、
[root@logicserver ~]# mogadm --trackers=10.1.2.180:7001 device add 10.1.2.201 002
3、
[root@logicserver ~]# mogadm --trackers=10.1.2.180:7001 host list
10.1.2.200 [1]: alive
IP: 10.1.2.200:7500
10.1.2.201 [2]: alive
IP: 10.1.2.201:7500
[root@logicserver ~]# mogadm --trackers=10.1.2.180:7001 device list
10.1.2.200 [1]: alive
used(G) free(G) total(G) weight(%)
dev1: alive 0.000 0.000 0.000 100
10.1.2.201 [2]: alive
used(G) free(G) total(G) weight(%)
dev2: alive 0.000 0.000 0.000 100
4、上传文件试试
4.1mogupload 用法
注意这里key，访问mogilefs时，所使用的http所访问的URL
[root@logicserver ~]# mogupload -h
Usage: /usr/bin/mogupload --trackers=host --domain=foo --key='/hello.jpg' --file='./hello.jpg' 4.2上传一个文件，有错误提示了
[root@logicserver ~]# mogupload --trackers=10.1.2.180:7001 --domain=files --key='fstab.html' --file='/etc/fstab'
Error opening MogileFS file: no_devices No devices found to store file at /usr/bin/mogupload line 83, line 1. 5.回到200主机，创建/data0/nfs/mogdata/dev1
[root@xenserver1 mogdata]# mkdir dev1[root@xenserver1 mogdata]# chown -R mogilefs.mogilefs dev1/
重启mogstored服务
6、201主机，创建/data0/nfs/mogdata/dev2
[root@hadoop3 mogdata]# mkdir dev2[root@hadoop3 mogdata]# chown -R mogilefs.mogilefs dev2/
7、
[root@logicserver ~]# mogadm --trackers=10.1.2.180:7001 device list
10.1.2.200 [1]: alive
used(G) free(G) total(G) weight(%)
dev1: alive 0.064 328.843 328.907 100
10.1.2.201 [2]: alive
used(G) free(G) total(G) weight(%)
dev2: alive 0.718 2.932 3.649 100
8、这时没有错示了
[root@logicserver ~]# mogupload --trackers=10.1.2.180:7001 --domain=files --key='fstab.html' --file='/etc/fstab'
9、列出所有key
[root@logicserver ~]# moglistkeys --trackers=10.1.2.180:7001 --domain=files
fstab.html
10、
[root@logicserver ~]# mogfileinfo --tracker=10.1.2.180:7001 --domain=files --key='fstab.html'
- file: fstab.html
class: default
devcount: 2
domain: files
fid: 4
key: fstab.html
length: 899
- http://10.1.2.201:7500/dev2/0/000/000/0000000004.fid
- http://10.1.2.200:7500/dev1/0/000/000/0000000004.fid
11、把第10步的URL其中一个复制粘贴到浏览器上，即可访问的到
八、常用操作，这里列出两个，可以查看帮助，有详细介绍
1、关闭201存储节点
[root@logicserver ~]# mogadm --trackers=10.1.2.180:7001 device -h
Help for 'device' command:
(enter any command prefix, leaving off options, for further help)
mogadm device add [opts] Add a device to a host.
mogadm device list [opts] List all devices, for each host.
mogadm device mark Mark a device as {alive,dead,down,drain,readonly}
