一、主機規劃
操作系統版本爲CentOS 7.2.1511
node1:172.17.0.1 gfs1
node2:172.17.0.2 gfs2
node3:172.17.0.3 gfs3
node4:172.17.0.4 gfs
client:172.17.0.5
二、安裝：
1.在node1-4上安裝glusterfs-server
yum install -y centos-release-gluster38
yum install -y glusterfs glusterfs-server glusterfs-fuse
設置開機自啓動並啓動
systemctl enable glusterd.service
systemctl start glusterd.service
2.在gfs1-gfs4節點上配置整個GlusterFS集羣，把各個節點加入到集羣
vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.17.0.1 gfs1
172.17.0.2 gfs2
172.17.0.3 gfs3
172.17.0.4 gfs4
[root@gfs1 ~]# gluster peer probe gfs1
[root@gfs1 ~]# gluster peer probe gfs2
[root@gfs1 ~]# gluster peer probe gfs3
[root@gfs1 ~]# gluster peer probe gfs4
3.查看節點狀態
[root@gfs1 ~]#gluster peer status
4.在gfs{1-4}上創建數據存儲目錄
# mkdir -p /usr/local/share/models
5.在gfs1上創建GlusterFS磁盤
注意：
加上replica 4就是4個節點中，每個節點都要把數據存儲一次，就是一個數據存儲4份，每個節點一份
如果不加replica 4，就是4個節點的磁盤空間整合成一個硬盤，
[root@gfs1 ~]#gluster volume create models replica 4 gfs1:/usr/local/share/models gfs2:/usr/local/share/models gfs3:/usr/local/share/models gfs4:/usr/local/share/models force
6.啓動
[root@gfs1 ~]# gluster volume start models
客戶端
1.部署GlusterFS客戶端並mount GlusterFS文件系統
[root@client ~]# yum install -y centos-release-gluster38
[root@client ~]# yum install -y glusterfs glusterfs-fuse
[root@client ~]# mkdir -p /mnt/models
[root@client ~]# mount -t glusterfs -o ro gfs1:models /mnt/models/
2.查看效果
[root@client ~]# df -h
3.觀察分佈式文件系統的效果
umount /mnt/models
mount -t glusterfs -o rw gfs1:models /mnt/models/
[root@client ~]# cd /mnt/models/
[root@client mnt]# for i in `seq -w 10`; do mkdir $i ; done
[root@client models]# for i in `seq -w 10`; do mkdir $i ; done
[root@client models]# ll
total 40
drwxr-xr-x 2 root root 4096 Feb 14 21:56 01
drwxr-xr-x 2 root root 4096 Feb 14 21:59 02
drwxr-xr-x 2 root root 4096 Feb 14 21:56 03
drwxr-xr-x 2 root root 4096 Feb 14 21:56 04
drwxr-xr-x 2 root root 4096 Feb 14 21:56 05
drwxr-xr-x 2 root root 4096 Feb 14 21:56 06
drwxr-xr-x 2 root root 4096 Feb 14 21:59 07
drwxr-xr-x 2 root root 4096 Feb 14 21:56 08
drwxr-xr-x 2 root root 4096 Feb 14 21:56 09
drwxr-xr-x 2 root root 4096 Feb 14 21:59 10
分別在4臺Server上查看新建的文件夾同步情況
[root@gfs1 ~]# ls /usr/local/share/models/ -l
total 0
drwxr-xr-x 2 root root 6 Feb 14 21:56 01
drwxr-xr-x 2 root root 6 Feb 14 21:59 02
drwxr-xr-x 2 root root 6 Feb 14 21:56 03
drwxr-xr-x 2 root root 6 Feb 14 21:56 04
drwxr-xr-x 2 root root 6 Feb 14 21:56 05
drwxr-xr-x 2 root root 6 Feb 14 21:56 06
drwxr-xr-x 2 root root 6 Feb 14 21:59 07
drwxr-xr-x 2 root root 6 Feb 14 21:56 08
drwxr-xr-x 2 root root 6 Feb 14 21:56 09
drwxr-xr-x 2 root root 6 Feb 14 21:59 10
可以看到4臺服務器都同步過來了。
當單臺Server出現故障，比如服務器斷開連接的情況，創建一個文件需要比較長的時間。
但是當Server重新連上之後，文件可以及時的同步過來。
