二、mogilefs原理
三、mogilefs架构说明
四、mogile安装部署
一、mogilefs介绍
MogileFS是我们的开源分布式文件系统。其性能和特点包括:
(1)应用程序级别 - 不需要特殊的内核模块。
没有单点故障 - MogileFS设置的所有三个组件(存储节点,跟踪器和跟踪器的数据库)可以在多台机器上运行,因此没有单点故障。 (您可以在与存储节点相同的计算机上运行跟踪器,因此您不需要4台计算机...)建议至少使用2台计算机。
(2)自动文件复制
基于文件“类”的文件在足够不同的存储节点之间自动复制,以满足其类所请求的最小复制计数。例如,对于照片托管网站,您可以使原始JPEG的最小副本计数为3,但缩略图和缩放版本只有副本计数为1或2.如果你失去了缩略图的唯一副本, 应用程序可以重建它。以这种方式,MogileFS(无RAID)可以在不必要地存储多个数据副本的磁盘上节省资金。
(3)比RAID更好
在非SAN RAID设置中,磁盘是冗余的,但主机不是。如果丢失整个机器,则文件无法访问。 MogileFS在不同主机上的设备之间复制文件,因此文件始终可用。
(4) Flat Namespace
文件由平面的全局命名空间中的命名键标识。您可以创建任意数量的命名空间,因此具有可能冲突的键的多个应用程序可以在同一个MogileFS安装上运行。
(5) Shared-Nothing
MogileFS不依赖于具有共享磁盘的昂贵的SAN。每台机器都维护自己的本地磁盘。
(6)不需要RAID
MogileFS存储节点上的本地磁盘可以位于RAID中,也可以不位于RAID中。它不是更便宜,因为RAID不会买你任何安全,MogileFS尚未提供。
(7)与本地文件系统无关联
MogileFS存储节点上的本地磁盘可以使用您选择的文件系统(ext3,XFS等)进行格式化。 MogileFS有自己的内部目录哈希,因此它不会遇到文件系统限制,如“每个目录的最大文件数”或“每个目录最大目录数”。使用你舒适的。
二、mogilefs原理
Tracker(mogilefsd进程):
基于事件的父进程/消息总线,管理来自应用程序的所有客户端通信(请求执行操作),包括将这些请求负载平衡到“查询工作器”,并处理mogilefsd子进程之间的所有通信。您应该在不同的主机上运行2个跟踪程序,为HA或更多负载均衡(如果您需要超过2)。 mogilefsd下的子进程包括:
Replication - 复制文件
Deletion- 命名空间中的删除是立即的;从文件系统的删除是异步的
Query - 应答来自客户端的请求
Reaper - 在磁盘发生故障后重新排列文件以进行复制
Monitor - 监视主机和设备的运行状况和状态
... ...
数据库
存储MogileFS元数据(命名空间,哪些文件位于哪里)的数据库。这应该在HA配置中设置,所以你没有单点故障。
存储节点
存储文件的位置。存储节点只是执行DELETE,PUT等的HTTP服务器。任何WebDAV服务器都很好,但建议使用mogstored。 mogilefsd可以配置为使用不同端口上的两个服务器... mogstored用于所有WebDAV操作(和边带监控),以及您的快速/轻量级HTTP服务器,用于GET操作。通常人们每个安装点有一个SATA磁盘,每个安装在/var/mogdata/devNN。
三、mogilefs架构说明
四、安装部署
mogilefs+tracker部署在47,48,49上,三个安装一致,这里只写47的安装方法
1.安装mogilefs
下载地址:https://github.com/mogilefs/
由于mogilefs没有提供rpm包,这里使用原生的安装方法,如果需要使用rpm,去下载他人生成好的RPM
1.1.安装需要的依赖包:
yum install perl-DBD-mysql perl-CPAN perl-YAML gcc-c++
添加用户
adduser mogilefs
1.2.安装MogileFS-Server
unzip MogileFS-Server-master.zip cd MogileFS-Server-master per Makefile.PL make make install
1.3.安装MogileFS-Network
cd MogileFS-Network-master/ perl Makefile.PL make make install
1.4.安装MogileFS-Utils
cd MogileFS-Utils-master/ per Makefile.PL make make install
1.5.安装perl-MogileFS-Client
cd perl-MogileFS-Client-master/ per Makefile.PL make make install
1.6.Perl安装插件
perl -MCPAN -e ‘install Danga::Socket‘ perl -MCPAN -e ‘install Gearman::Client‘ perl -MCPAN -e ‘install Gearman::Server‘ perl -MCPAN -e ‘install Gearman::Client::Async‘ perl -MCPAN -e ‘install Net::Netmask‘ perl -MCPAN -e ‘install IO::WrapTie‘ perl -MCPAN -e ‘install IO::AIO‘ perl -MCPAN -e ‘install List::MoreUtils‘ perl -MCPAN -e ‘install Path::Class‘ perl -MCPAN -e ‘install Perlbal‘
2.配置数据库
数据库172.16.110.50
2.1.数据库安装略过
2.2.创建数据库及添加账号
添加root管理账号
MariaDB [mysql]> grant all on *.* to ‘root‘@‘172.16.110.%‘ identified by ‘ckl893‘; Query OK, 0 rows affected (0.01 sec)
创建数据库:
MariaDB [mysql]> create database mogilefs; Query OK, 1 row affected (0.00 sec)
添加mogilefs远程连接用户:
MariaDB [mysql]> grant all on mogilefs.* to ‘moguser‘@‘172.16.110.%‘ identified by ‘mogpass‘; Query OK, 0 rows affected (0.00 sec)
2.3.生成数据表操作
修改生成脚本:
# vim mogdbsetup .... my %args = ( dbhost => "172.16.110.50", dbport => 3306, dbname => "mogilefs", dbrootuser => "root", dbrootpass => "ckl893", dbuser => "moguser", dbpass => "mogpass", ); ....
在47上生成数据库表:
./mogdbsetup --dbhost=172.16.110.50 --dbname=mogilefs --dbuser=moguser --dbpassword=mogpass 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
查看数据表:
MariaDB [mogilefs]> show tables; +----------------------+ | Tables_in_mogilefs | +----------------------+ | checksum | | class | | device | | domain | | file | | file_on | | file_on_corrupt | | file_to_delete | | file_to_delete2 | | file_to_delete_later | | file_to_queue | | file_to_replicate | | fsck_log | | host | | server_settings | | tempfile | | unreachable_fids | +----------------------+ 17 rows in set (0.00 sec)
3.配置文件及脚本
3.1.创建配置文件目录及权限
mkdir /etc/mogilefs/ chown -R mogilefs.mogilefs /etc/mogilefs/ cp /tmp/soft/MogileFS-Server-master/conf/mogilefsd.conf /etc/mogilefs/ cp /tmp/soft/MogileFS-Server-master/conf/mogstored.conf /etc/mogilefs/
3.2.mogilefsd配置文件说明
#vim /etc/mogilefs/mogilefsd.conf daemonize = 1 守护进程运行 pidfile = /var/run/mogilefsd/mogilefsd.pid pid文件 db_dsn = DBI:mysql:mogilefs:host=172.16.110.50 指定数据库连接地址 db_user = moguser 数据库连接用户 db_pass = mogpass 数据库连接密码 listen = 0.0.0.0:7001 tracker监听端口 conf_port = 7001 配置端口 query_jobs = 10 查询线程 delete_jobs = 1 删除线程 replicate_jobs = 5 复制线程 reaper_jobs = 1 复制线程
3.3.mogstored配置文件说明
#vim /etc/mogilefs/mogstored.conf maxconns = 10000 #最大连接数 httplisten = 0.0.0.0:7500 #访问端口 mgmtlisten = 0.0.0.0:7501 #管理端口 docroot = /var/mogdata #数据目录 pidfile = /var/run/mogstored/mogstored.pid #pid文件,如果脚本指定,这里必须有
3.4.mogilefsd启动脚本
vim /etc/init.d/mogilefsd #!/bin/sh # # mogilefsd Startup script for the MogileFS tracker # # chkconfig: - 85 15 # description: MogileFS tracker # processname: mogilefsd # config: /etc/mogilefs/mogilefs.conf # pidfile: /var/run/mogilefsd/mogilefsd.pid # Source function library. . /etc/init.d/functions # Check that networking is up. . /etc/sysconfig/network # Check that networking is up.

3.6.启动进程:
启动查看mogilefsd进程
# systemctl start mogilefsd.service # ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 *:111 *:* LISTEN 0 128 *:22 *:* LISTEN 0 128 *:7001 *:* LISTEN 0 100 127.0.0.1:25 *:* LISTEN 0 128 :::111 :::* LISTEN 0 128 :::22 :::* LISTEN 0 100 ::1:25 :::*
启动查看mogstored进程:
# systemctl status mogstored.service # ss -ntl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 *:7500 *:* LISTEN 0 128 *:7501 *:* LISTEN 0 128 *:111 *:* LISTEN 0 128 *:22 *:* LISTEN 0 128 *:7001 *:* LISTEN 0 100 127.0.0.1:25 *:* LISTEN 0 128 :::111 :::* LISTEN 0 128 :::22 :::* LISTEN 0 100 ::1:25 :::*
4.添加节点
为每个host增加节点,方法一直,随便选择一个tracker即可
4.1.增加节点:
# mogadm --trackers=172.16.110.47:7001 host add node1 --ip=172.16.110.47 --status=alive # mogadm --trackers=172.16.110.48:7001 host add node2 --ip=172.16.110.48 --status=alive # mogadm --trackers=172.16.110.49:7001 host add node3 --ip=172.16.110.49 --status=alive
删除节点:
mogadm --trackers=172.16.110.49:7001 host delete node1
查看增加的节点:
# mogadm --trackers=172.16.110.49:7001 host list node1 [1]: alive IP: 172.16.110.47:7500 node2 [2]: alive IP: 172.16.110.48:7500 node3 [3]: alive IP: 172.16.110.49:7500
4.2.添加设备存储节点:
(注意,最后一列的ID号同创建的目录的序号,如dev4 就是 4)
# mogadm --trackers=172.16.110.49:7001 device add node1 4 # mogadm --trackers=172.16.110.49:7001 device add node2 5 # mogadm --trackers=172.16.110.49:7001 device add node3 6
创建物理存储节点路径:
node1:
mkdir -pv /var/mogdata/dev4 chown -R mogilefs.mogilefs /var/mogdata/dev4
node2:
mkdir -pv /var/mogdata/dev5 chown -R mogilefs.mogilefs /var/mogdata/dev5
node3:
mkdir -pv /var/mogdata/dev6 chown -R mogilefs.mogilefs /var/mogdata/dev6
查看添加的节点:
# mogadm --trackers=172.16.110.49:7001 device list node1 [1]: alive used(G) free(G) total(G) weight(%) dev4: alive 1.786 6.200 7.986 100 node2 [2]: alive used(G) free(G) total(G) weight(%) dev5: alive 1.792 6.194 7.986 100 node3 [3]: alive used(G) free(G) total(G) weight(%) dev6: alive 1.928 6.059 7.986 100
删除设备存储节点:
mogadm --trackers=172.16.110.49:7001 device mark node1 1 dead
4.3.检查节点状态:
# mogadm --trackers=172.16.110.49:7001 check Checking trackers... 172.16.110.49:7001 ... OK Checking hosts... [ 1] node1 ... OK [ 2] node2 ... OK [ 3] node3 ... OK Checking devices... host device size(G) used(G) free(G) use% ob state I/O% ---- ------------ ---------- ---------- ---------- ------ ---------- ----- [ 1] dev4 7.986 1.786 6.200 22.37% writeable 0.0 [ 2] dev5 7.986 1.793 6.193 22.45% writeable 0.0 [ 3] dev6 7.986 1.929 6.058 24.15% writeable 0.0 ---- ------------ ---------- ---------- ---------- ------ total: 23.959 5.508 18.451 22.99%
5.添加域
5.1.创建域:
# mogadm --trackers=172.16.110.49:7001 domain add img # mogadm --trackers=172.16.110.49:7001 domain add html # mogadm --trackers=172.16.110.49:7001 domain add file
查看域信息:
# mogadm --trackers=172.16.110.49:7001 domain list domain class mindevcount replpolicy hashtype -------------------- -------------------- ------------- ------------ ------- file default 2 MultipleHosts() NONE html default 2 MultipleHosts() NONE img default 2 MultipleHosts() NONE
6.添加类
默认会创建默认类,这里我们创建测试:
6.1.默认类:
# mogadm --trackers=172.16.110.49:7001 class list domain class mindevcount replpolicy hashtype -------------------- -------------------- ------------- ------------ ------- file default 2 MultipleHosts() NONE html default 2 MultipleHosts() NONE img default 2 MultipleHosts() NONE
6.2.创建自定义类:
# mogadm --trackers=172.16.110.49:7001 class add html ckltext --mindevcount=3
查看类列表:
# mogadm --trackers=172.16.110.49:7001 class list domain class mindevcount replpolicy hashtype -------------------- -------------------- ------------- ------------ ------- file default 2 MultipleHosts() NONE html ckltext 3 MultipleHosts() NONE html default 2 MultipleHosts() NONE img default 2 MultipleHosts() NONE
7.文件上传
7.1.上传测试:
