1、环境规划如下

centos7.4   三个节点一块 sdb  3G大小的测试硬盘

2、Glusterfs  卷的类型比较多,这里我们测试最常用的一种   Distributed Replicated Glusterfs Volume,架构如下

3、安装部署

1、准备yum源
yum install centos-release-gluster -y

2、Format and mount the bricks  三个节点操作
[root@glusterfs1 ~]# fdisk /dev/sdb
Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

设置 GlusterFS volume

[root@glusterfs1 ~]# mkdir -p /storage/brick1   #每个节点都需要操作

 

[root@glusterfs1 ~]# gluster volume create gv0 replica 3 glusterfs1:/storage/brick1 glusterfs2:/storage/brick1 glusterfs3:/storage/brick1 force  #创建分布式的复制卷
volume create: gv0: success: please start the volume to access data
[root@glusterfs1 ~]#
[root@glusterfs1 ~]# gluster volume start gv0
volume start: gv0: success
[root@glusterfs1 ~]# gluster volume info

Volume Name: gv0
Type: Replicate
Volume ID: 18bfd54d-43b0-4be8-85d6-2b385db61dc4
Status: Started
Snapshot Count: 0
Number of Bricks: 1 x 3 = 3
Transport-type: tcp
Bricks:
Brick1: glusterfs1:/storage/brick1
Brick2: glusterfs2:/storage/brick1
Brick3: glusterfs3:/storage/brick1
Options Reconfigured:
transport.address-family: inet
nfs.disable: on
performance.client-io-threads: off

 

 Testing the GlusterFS volume

[root@glusterfs1 ~]# mount -t glusterfs glusterfs1:/gv0 /mnt
[root@glusterfs1 ~]# for i in `seq -w 1 100`; do cp -rp /var/log/messages /mnt/copy-test-$i; done
[root@glusterfs1 ~]# ls -lA /mnt/copy* | wc -l
100
