分佈式文件系統Glusterfsnode
Gluster File System 是自由軟件,主要由 Z RESEARCH 公司負責開發,十幾名開發者,最近很是活躍。主要應用在集羣系統中,具備很好的可擴展性。軟件的結構設計良好,易於擴展和配置,經過各個模塊的靈活搭配以獲得針對性的解決方案。可解決如下問題:網絡存儲,聯合存儲(融合多個節點上的存儲空間),冗餘備份,大文件的負載均衡(分塊)。服務器
準備三臺機器:網絡
[root@node1 data]# cat /etc/redhat-release負載均衡
CentOS release 6.8 (Final)tcp
Node1: 分佈式 |
192.168.70.71 ide |
serverui |
Node2:url |
192.168.70.72spa |
server |
Node3: |
192.168.70.73 |
client |
vi /etc/sysconfig/iptables:
-A INPUT -m state--state NEW -m tcp -p tcp --dport 24007:24008 -j ACCEPT
-A INPUT -m state --stateNEW -m tcp -p tcp --dport 49152:49162 -j ACCEPT
service iptables restart
Server1和server2下都執行如下操做:
安裝方法1:
·
wget -l 1 -nd -nc -r -A.rpmhttp://download.gluster.org/pub/gluster/glusterfs/3.7/LATEST/CentOS/epel-6Server/x86_64/
wget -l 1 -nd -nc -r -A.rpmhttp://download.gluster.org/pub/gluster/glusterfs/3.7/LATEST/CentOS/epel-6Server/noarch/
wget -nc
http://download.gluster.org/pub/gluster/nfs-ganesha/2.3.0/EPEL.repo/epel-6Server/x86_64/nfs-ganesha-gluster-2.3.0-1.el6.x86_64.rpm
yum install * -y
方法二:(不一樣版本)
mkdir tools
cd /tools
wget -l 1 -nd -nc -r -A.rpm http://download.gluster.org/pub/gluster/glusterfs/3.5/3.5.5/RHEL/epel-6/x86_64/
yum install *.rpm
開啓gluster服務
/etc/init.d/glusterd start
設置glusterFS服務開機啓動
chkconfig glusterd on
[root@node1 /]# gluster peer probe 192.168.70.72
peer probe: success.
[root@node1 /]# gluster peer status
Number of Peers: 1
Hostname: 192.168.70.72
Uuid: fdc6c52d-8393-458a-bf02-c1ff60a0ac1b
State: Accepted peer request (Connected)
[root@node1 /]# gluster peer detach 192.168.70.72
peer detach: success
[root@node1 /]# gluster peer status
Number of Peers: 0
在node1和node2分別創建mkdir /data/gfs/
mkdir /data/gfs/
建立邏輯卷、
gluster volume create vg0 replica 2192.168.70.71:/data/gfs 192.168.70.72:/data/gfs force
volume create: vg0: success: please startthe volume to access data
查看邏輯卷信息
[root@node1 /]# gluster volume info
Volume Name: vg0
Type: Replicate
Volume ID: 6aff1f4f-8efe-4ed0-879e-95df483a86a2
Status: Created
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: 192.168.70.71:/data/gfs
Brick2: 192.168.70.72:/data/gfs
[root@node1 /]# gluster volume status
Volume vg0 is not started
開啓邏輯卷
[root@node1 /]# gluster volume start vg0
volume start: vg0: success
yum -y install glusterfs glusterfs-fuse
mount -t glusterfs 192.168.70.71:/gv0/mnt/gfs
# 卷擴容(因爲副本數設置爲2,至少要添加2(4、6、8..)臺機器)
gluster peer probe 192.168.70.74 # 加節點
gluster peer probe 192.168.70.75 # 加節點
gluster volume add-brick gv0 192.168.70.74:/data/glusterfs192.168.70.75:/data/glusterfs # 合併卷
收縮卷(收縮卷前gluster須要先移動數據到其餘位置)
gluster volume remove-brick gv0 192.168.70.74:/data/glusterfs 192.168.70.75:/data/glusterfsstart # 開始遷移
gluster volume remove-brick gv0 192.168.70.74:/data/glusterfs192.168.70.74:/data/glusterfsstatus # 查看遷移狀態
gluster volume remove-brick gv0 192.168.70.74:/data/glusterfs192.168.70.74:/data/glusterfs commit # 遷移完成後提交
# 遷移卷
