CentOS7下分布式系统GlusterFS安装配置

一、主机规划

操作系统版本为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、安装:

1.在node1-4上安装glusterfs-server

yum install -y centos-release-gluster38

yum install -y glusterfs glusterfs-server glusterfs-fuse


设置开机自启动并启动

systemctl enable glusterd.service

systemctl start glusterd.service


2.在gfs1-gfs4节点上配置整个GlusterFS集群,把各个节点加入到集群

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.查看节点状态

[root@gfs1 ~]#gluster peer status


4.在gfs{1-4}上创建数据存储目录

# mkdir -p  /usr/local/share/models


5.在gfs1上创建GlusterFS磁盘

注意:

加上replica 4就是4个节点中,每个节点都要把数据存储一次,就是一个数据存储4份,每个节点一份

如果不加replica 4,就是4个节点的磁盘空间整合成一个硬盘,

[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.启动

[root@gfs1 ~]# gluster volume start models


客户端

1.部署GlusterFS客户端并mount GlusterFS文件系统

[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.观察分布式文件系统的效果

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


分别在4台Server上查看新建的文件夹同步情况

[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台服务器都同步过来了。


当单台Server出现故障,比如服务器断开连接的情况,创建一个文件需要比较长的时间。

但是当Server重新连上之后,文件可以及时的同步过来。
