一：服务器端：
1.下载相应的安装包
(1) yum install lvm2 (下载Linux端磁盘管理工具lvm)
(2) yum install rpcbind (rpcbind就是为了将不同服务与对应的端口进行绑定，以便支持机器间的互操作)
(3)rpm -ivh (安装如下4个包)

2.添加到开机启动
chkconfig glusterd on
3.启动服务进程
/etc/init.d/glusterd start
以上操作在每台服务端上执行。
二：客户端
1.# yum install -y fuse fuse-libs
# modprobe fuse
2.# rpm -ivh

3.# mount -t glusterfs 192.168.1.1:/web-files /mnt
三．挂载步骤：
1:服务器端：将服务器端组成员统一添加到管理池中，每台服务器端是对等的不分主次。
# gluster peer probe 192.168.1.2
peer probe: success
查看集群状态
# gluster peer status
Number of Peers: 1
Hostname: 192.168.1.2
Port: 24007
Uuid: b1eddb73-4ef9-4e9c-8dd2-90988d21296c
State: Peer in Cluster (Connected)
创建名为web-files的卷,副本数(replica)为2
# mkdir /data/app_test
#gluster volume create web-file replica 2 10.20.216.173:/data/app_test/ 10.20.216.174:/data/app_test/
http://blog.csdn.net/liuaigui/article/details/7009782 #创建不同类型的卷
# gluster volume create web-files replica 2 192.168.1.1:/data/gluster/web-files 192.168.1.2:/data/gluster/web-files
volume create: web-files: success: please start the volume to access data
启动卷
# gluster volume start web-files
volume start: web-files: success
查看卷状态
# gluster volume info
Volume Name: web-files
Type: Replicate
Volume ID: 4e943de6-3101-4c96-8a32-48548f34c88a
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: 192.168.1.1:/data/gluster/web-files
Brick2: 192.168.1.2:/data/gluster/web-files
客户端：
# mount -t glusterfs 10.20.216.173:/web-file /data/app/
# df -h

2.挂载本地目录到glusterfs服务器端的
http://blog.chinaunix.net/uid-1839523-id-3450679.html
问题：报错如下信息
volume create: CDN_web_data: failed: /data/app_glusterfs or a prefix of it is already part of a volume
从glusterfs 3.3开始，有个变化：gluster 会一直check 目录是否已经是volume的一部分，如果你将brick从volume移除后再次使用时，会导致许多问题，甚至是数据丢失。
目的是重用原来的brick时，需要让你知道你在做什么
需要重用原来brick时，执行如下操作
setfattr -x trusted.glusterfs.volume-id $brick_path
setfattr -x trusted.gfid $brick_path
rm -rf $brick_path/.glusterfs
重启glusterd 服务即可
或者如下脚本：
#! /bin/sh
read -p "Enter you will reuse brick path:" brick_path
setfattr -x trusted.glusterfs.volume-id $brick_path
setfattr -x trusted.gfid $brick_path
rm -rf $brick_path/.glusterfs
service glusterd restart
