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GFS，google的googlefs，开源的现在也越来越多，像Fastdfs，ZFS，Lustre，Hadoop，GlusterFS。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。在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fuse，fuse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 Copyright (c) 2006, 2007, 2008 Z RESEARCH Inc. <http://www.zresearch.com/> GlusterFS comes with ABSOLUTELY NO WARRANTY.

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.repo1.2、server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

2、server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linux，ip分别Server：192.168.211.128 client：192.168.211.129，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client端mount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
