GlusterFS是一个开源的分布式文件系统,于2011年被红帽收购.它具有高扩展性、高性能、高可用性、可横向扩展的弹性特点,无元数据服务器设计使glusterfs没有单点故障隐患，详细介绍请查看官网：www.gluster.org 。
部署环境：
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
具体操作：
| 代码如下 | 复制代码 |
| c1/c2/c3/c4上执行 [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
| 代码如下 | 复制代码 |
|
[root@c1 ~]# gluster peer probe c1 peer probe: success. Probe on localhost not needed [root@c1 ~]# gluster peer probe c2 peer probe: success. |
|
如果c1在peer表中被识别为ip地址，可能后面集群过程中会出现通讯问题，
我们可以使用ip来进行修复:
| 代码如下 | 复制代码 |
|
[root@c3 ~]# gluster peer status Number of Peers: 3 Hostname: 192.168.242.132 Hostname: c2 Hostname: c4 Hostname: c2 Hostname: c4 Hostname: c1 |
|
c1上创建集群磁盘
| 代码如下 | 复制代码 |
|
[root@c1 ~]# gluster volume create datavolume1 replica 2 transport tcp c1:/usr/local/share/datavolume1 c2:/usr/local/share/datavolume1 c3:/usr/local/share/datavolume1 c4:/usr/local/share/datavolume1 force volume create: datavolume1: success: please start the volume to access data [root@c1 ~]# gluster volume create datavolume2 replica 2 transport tcp c1:/usr/local/share/datavolume2 c2:/usr/local/share/datavolume2 c3:/usr/local/share/datavolume2 c4:/usr/local/share/datavolume2 force volume create: datavolume2: success: please start the volume to access data [root@c1 ~]# gluster volume create datavolume3 replica 2 transport tcp c1:/usr/local/share/datavolume3 c2:/usr/local/share/datavolume3 c3:/usr/local/share/datavolume3 c4:/usr/local/share/datavolume3 force volume create: datavolume3: success: please start the volume to access data [root@c1 ~]# gluster volume start datavolume1 volume start: datavolume1: success [root@c1 ~]# gluster volume start datavolume2 volume start: datavolume2: success [root@c1 ~]# gluster volume start datavolume3 volume start: datavolume3: success [root@c1 ~]# gluster volume info Volume Name: datavolume1 Volume Name: datavolume2 Volume Name: datavolume3 |
|
客户端环境部署
| 代码如下 | 复制代码 |
| Centos OS 6.5 x64 并加入hosts [root@c5 ~]#wget -P /etc/yum.repos.d http://download.gluster.org/pub/gluster/glusterfs/LATEST/CentOS/glusterfs-epel.repo [root@c5 ~]#yum install -y glusterfs glusterfs-fuse [root@c5 ~]# mkdir -p /mnt/{datavolume1,datavolume2,datavolume3} [root@c5 ~]# mount -t glusterfs -o ro c1:datavolume1 /mnt/datavolume1/ [root@c5 ~]# mount -t glusterfs -o ro c1:datavolume2 /mnt/datavolume2/ [root@c5 ~]# mount -t glusterfs -o ro c1:datavolume3 /mnt/datavolume3/ me3 [root@c5 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup-lv_root 38G 840M 36G 3% / tmpfs 242M 0 242M 0% /dev/shm /dev/sda1 485M 32M 429M 7% /boot c1:datavolume1 57G 2.4G 52G 5% /mnt/datavolume1 c1:datavolume2 57G 2.4G 52G 5% /mnt/datavolume2 c1:datavolume3 57G 2.4G 52G 5% /mnt/datavolume3 |
