GlusterFS学习手记01-初步了解及简单的配置应用


对于分布式存储已经被越来越多的公司所应用,对于这方面的学习自然不能忽略,之前就也看过相关的内容,像红帽的GFSgooglegooglefs,开源的现在也越来越多,像FastdfsZFSLustreHadoopGlusterFS

大概的也都接触了一下,Fastdfs号称小巧,速度快占用资源小,但据我了解他是提供api来进行操作的,而目前我还是希望可以像NFS一样,直接mount来使用,并且提供高的可用性,和文件的容错功能,一路扫下来,瞄准了glusterfs

Glusterfs是一个具有可以扩展到几个PB数量级的集群文件系统。它可以把多个不同类型的存储块通过InfinibandRDMA或者TCP/IP汇聚成一个大的并行网络文件系统。

http://www.gluster.org/可以了解到更多并可以下载到最新的安装包,glusterfs使用了fusefuse可以到http://fuse.sourceforge.net/进行下载

首先是fuse的安装

./configure --enable-dependency-tracking  --enable-kernel-module --enable-lib --enable-util
 make
 make install

如果没有什么错误,就是安装完毕了,接下来是glusterfs的安装

tar zxvf glusterfs-2.0.0rc1.tar.gz
 ./configure
 make
 make install

如果没有报错就是安装完毕了
然后执行ldconfig
执行完毕后执行
glusterfs --version
可以看到

glusterfs 2.0.0rc1 built on Feb 10 2009 11:39:40
 Repository revision: glusterfs--mainline--3.0--patch-844

说明glusterfs已经正确安装完毕了

yum下载及安装

1.1、下载yum源:

wget -P /etc/yum.repos.dhttp://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/glusterfs-epel.repo

1.2server端安装相关包:

yum installautomake autoconf flex libtool python-ctypes glusterfs gluster-fuse glusterfs-geo-replication  glusterfs-server


1.3、客户端安装相关包

yum installglusterfs gluster-fuse glusterfs-geo-replication

2server端启动/停止服务:

# serviceglusterd start               启动

# serviceglusterd stop               停止

下面来做个简单的配置,类似NFS的配置

环境:vmware6.0 模拟两个linuxip分别Server192.168.211.128 client192.168.211.129,软件都已经安装完毕

server端的配置

先建立需要share的文件夹
 make -p /home/dir1
 chmod 1777 /home/dir1
然后建立配置文件
 vi /etc/glusterfs/server.vol


 ### file: server-volume.vol.sample

#####################################
 ### GlusterFS Server Volume File ##
 #####################################

#### CONFIG FILE RULES:
 ### "#" is comment character.
 ### - Config file is case sensitive
 ### - Options within a volume block can be in any order.
 ### - Spaces or tabs are used as delimitter within a line.
 ### - Multiple values to options will be : delimitted.
 ### - Each option should end within a line.
 ### - Missing or commented fields will assume default values.
 ### - Blank/commented lines are allowed.
 ### - Sub-volumes should already be defined above before referring.

### Export volume "brick" with the contents  of "/home/export" directory.
 volume brick
 type storage/posix # POSIX FS translator
 option directory /home/dir1 # Export this directory
 end-volume

### Add network serving capability to above brick.
 volume server
 type protocol/server
 option transport-type tcp/server
 option bind-address 192.168.211.128 # Default is to listen on all interfaces
 option listen-port 6996 # Default is 6996
 subvolumes brick
 option auth.addr.brick.allow * # Allow access to "brick" volume
 end-volume

client端的配置

modprobe -i fuse
 vi /etc/glusterfs/client.vol

### file: client-volume.vol.sample

#####################################
 ### GlusterFS Client Volume File ##
 #####################################

#### CONFIG FILE RULES:
 ### "#" is comment character.
 ### - Config file is case sensitive
 ### - Options within a volume block can be in any order.
 ### - Spaces or tabs are used as delimitter within a line.
 ### - Each option should end within a line.
 ### - Missing or commented fields will assume default values.
 ### - Blank/commented lines are allowed.
 ### - Sub-volumes should already be defined above before referring.

### Add client feature and attach to remote subvolume
 volume client0
 type protocol/client
 option transport-type tcp/client
 option remote-host 192.168.211.128 # IP address of the remote brick
 option remote-port 6996 # default server port is 6996
 option remote-subvolume brick # name of the remote volume
 end-volume

这样两台机器就都配置完毕了

首先在server上启动服务

gulsterfsd -f /etc/glusterfs/server.vol

[root@contos5-1-1 etc]# ps ax|grep -v grep |grep  gluster
 2028 ? Ssl 0:00 glusterfsd -f ./server.vol

看到这个证明服务器端就启动了

接下来是client端的启动

glusterfs -l /tmp/glustfs.log -f /etc/glusterfs/client.vol  /mnt/

[root@contos5-1-4 glusterfs]# df -h
 Filesystem Size Used Avail Use% Mounted on
 /dev/sda3 7.1G 2.5G 4.3G 37% /
 /dev/sda1 190M 11M 170M 7% /boot
 tmpfs 125M 0 125M 0% /dev/shm
glusterfs 7.1G  2.9G 3.9G 43% /mnt

看到这个了,就说明clientmount正常,如果没有请查看/tmp/glusterfs.log文件

到此,一个简单的1存储1客户端的配置就完成了,这篇文章仅仅是个开始,glusterfs还有很多的功能,我也会在以后的时间进行深入的研究,希望有相同兴趣的朋友一起讨论
