环境规划
server
node1:192.168.0.165 主机名:glusterfs1
node2:192.168.0.157 主机名:glusterfs2
node3:192.168.0.166 主机名:glusterfs3
node4:192.168.0.150 主机名:glusterfs4
client
192.168.0.164 主机名:master3
实验前准备
192.168.0.165 glusterfs1
192.168.0.157 glusterfs2
192.168.0.166 glusterfs3
192.168.0.150 glusterfs4
192.168.0.164 master3
安装
服务端
1.在glusterfs {1-4}节点上安装GlusrerFS软件包
# wget -P /etc/yum.repos.d
# yum install -y glusterfs glusterfs-server glusterfs-fuse
# service gluterd start
# chkconfig gluterd on
2.在glusterfs1节点上配置整个GlusterFS集群,把各个节点加入到集群
[root@glusterfs1 ~]# gluster peer probe glusterfs1
1 peer probe: success: on localhost not needed
[root@glusterfs1 ~]# gluster peer probe glusterfs2
1 peer probe: success
[root@glusterfs1 ~]# gluster peer probe glusterfs2
1 peer probe: success
[root@glusterfs1 ~]# gluster peer probe glusterfs2
1 peer probe: success
3.查看节点状态
[root@glusterfs1 ~]#gluster peer status
4.在glusterfs{1-4}上创建数据存储目录
# mkdir -p /usr/local/share/models
5.在glusterfs1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@glusterfs1 ~]#gluster volume create models replica 4 glusterfs1:/usr/local/share/models glusterfs2:/usr/local/share/models glusterfs3:/usr/local/share/models glusterfs4:/usr/local/share/models force
1 volume create: models: success: please start the volume to access data
6.启动
[root@glusterfs1 ~]# gluster volume start models
客户端
1.部署GlusterFS客户端并mount GlusterFS文件系统
[root@master3 ~]# wget -P /etc/yum.repos.d
[root@master3 ~]# yum install -y glusterfs glusterfs-fuse
[root@master3 ~]# mkdir -p /mnt/models
[root@master3 ~]# mount -t glusterfs -o ro glusterfs1:models /mnt/models/
2.查看效果
[root@master3 ~]# df -h

其他操作命令
删除GlusterFS磁盘
# gluster volume stop models 先停止
# gluster volume delete models 再删除
卸载GlusterFS磁盘
gluster peer detach glusterfs4
ACL访问控制
gluster volume set models auth.allow 10.60.1.*,10.70.1.*
添加GlusterFS节点
# gluster peer probe sc2-log5
# gluster peer probe sc2-log6
# gluster volume add-brick models sc2-log5:/data/gluster sc2-log6:/data/gluster
迁移GlusterFS数据
# gluster volume remove-brick models sc2-log1:/usr/local/share/models sc2-log5:/usr/local/share/models start
# gluster volume remove-brick models sc2-log1:/usr/local/share/models sc2-log5:/usr/local/share/models status
# gluster volume remove-brick models sc2-log1:/usr/local/share/models sc2-log5:/usr/local/share/models commit
修复GlusterFS数据(在节点1宕机的情况下)
# gluster volume replace-brick models sc2-log1:/usr/local/share/models sc2-log5:/usr/local/share/models commit -force
# gluster volume heal models full
