GlusterFS如何安裝與配置

小編給大家分享一下GlusterFS如何安裝與配置，相信大部分人都還不怎么了解，因此分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后大有收獲，下面讓我們一起去了解一下吧！

GlusterFS是一個開源的分布式文件系統,于2011年被紅帽收購.它具有高擴展性、高性能、高可用性、可橫向擴展的彈性特點,無元數據服務器設計使glusterfs沒有單點故障隱患，詳細介紹請查看官網：www.gluster.org 。

部署環境： 
OS: CentOS release 6.5 (Final) x64 
Server: 
c1:192.168.242.132 
c2:192.168.242.133 
c3:192.168.242.134 
c4:192.168.242.135 
hosts： 
192.168.242.132 c1 
192.168.242.133 c2 
192.168.242.134 c3 
192.168.242.135 c4

具體操作： 
c1/c2/c3/c4上執行 
[root@c1 ~]# wget -P /etc/yum.repos.d http://download.gluster.org/pub/gluster/glusterfs/LATEST/CentOS/glusterfs-epel.repo 
[root@c1 yum.repos.d]# yum install -y glusterfs glusterfs-server glusterfs-fuse 
[root@c1 yum.repos.d]# /etc/init.d/glusterd start 
Starting glusterd: [ OK ] 
[root@c1 yum.repos.d]# chkconfig glusterd on

c1上配置集群 
[root@c1 ~]# gluster peer probe c1 
peer probe: success. Probe on localhost not needed 
[root@c1 ~]# gluster peer probe c2

peer probe: success. 
[root@c1 ~]# gluster peer probe c3 
peer probe: success. 
[root@c1 ~]# gluster peer probe c4 
peer probe: success.

如果c1在peer表中被識別為ip地址，可能后面集群過程中會出現通訊問題， 
我們可以使用ip來進行修復: 
[root@c3 ~]# gluster peer status 
Number of Peers: 3

Hostname: 192.168.242.132 
Uuid: 6e8d6880-ec36-4331-a806-2e8fb4fda7be 
State: Peer in Cluster (Connected)

Hostname: c2 
Uuid: 9a722f50-911e-4181-823d-572296640486 
State: Peer in Cluster (Connected)

Hostname: c4 
Uuid: 1ee3588a-8a16-47ff-ba59-c0285a2a95bd 
State: Peer in Cluster (Connected) 
[root@c3 ~]# gluster peer detach 192.168.242.132 
peer detach: success 
[root@c3 ~]# gluster peer probe c1 
peer probe: success. 
[root@c3 ~]# gluster peer status 
Number of Peers: 3

Hostname: c2 
Uuid: 9a722f50-911e-4181-823d-572296640486 
State: Peer in Cluster (Connected)

Hostname: c4 
Uuid: 1ee3588a-8a16-47ff-ba59-c0285a2a95bd 
State: Peer in Cluster (Connected)

Hostname: c1 
Uuid: 6e8d6880-ec36-4331-a806-2e8fb4fda7be 
State: Peer in Cluster (Connected)

刪除GlusterFS磁盤： 
gluster volume stop datavolume1 
gluster volume delete datavolume1

卸載GlusterFS磁盤： 
gluster peer detach idc1-server4

訪問控制： 
gluster volume set datavolume1 auth.allow 192.168.242.*,192.168.241.*

添加GlusterFS節點： 
gluster peer probe c6 
gluster peer probe c7 
gluster volume add-brick datavolume1 c6:/usr/local/share/datavolume1 c7:/usr/local/share/datavolume1

遷移GlusterFS磁盤數據： 
gluster volume remove-brick datavolume1 c1:/usr/local/share/datavolume1 c6:/usr/local/share/datavolume1 start 
gluster volume remove-brick datavolume1 c1:/usr/local/share/datavolume1 c6:/usr/local/share/datavolume1 status 
gluster volume remove-brick datavolume1 c1:/usr/local/share/datavolume1 c6:/usr/local/share/datavolume1 commit

數據重新分配： 
gluster volume rebalance datavolume1 start 
gluster volume rebalance datavolume1 status 
gluster volume rebalance datavolume1 stop

修復GlusterFS磁盤數據（例如在c1宕機的情況下）： 
gluster volume replace-brick datavolume1 c1:/usr/local/share/datavolume1 c6:/usr/local/share/datavolume1 commit -force 
gluster volume heal datavolume1 full
