centos7 搭建GlusterFS

实验需求:
·4台机器安装GlusterFS组成一个集群
·客户端把docker registry存储到文件系统里
·4个节点的硬盘空间不整合成一个硬盘空间,要求每个节点都存储一份,保证数据安全
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
·所有主机关闭防火墙,SElinux
·修改hosts文件,能够互相解析

安装
服务端
1.在glusterfs {1-4}节点上安装GlusrerFS软件包

1
2
3
4
# 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

# gluster peer probe glusterfs1
1 peer probe: success: on localhost not needed
# gluster peer probe glusterfs2
1 peer probe: success
# gluster peer probe glusterfs2
1 peer probe: success
# gluster peer probe glusterfs2
 1 peer probe: success




3.查看节点状态

1
#gluster peer status




4.在glusterfs{1-4}上创建数据存储目录

1
# 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,

1
2
#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

1
# gluster volume start models




客户端
1.部署GlusterFS客户端并mount GlusterFS文件系统

1
2
3
4
# wget -P /etc/yum.repos.d
# yum install -y glusterfs glusterfs-fuse
# mkdir -p /mnt/models
# mount -t glusterfs -o ro glusterfs1:models /mnt/models/




2.查看效果

其他操作命令
删除GlusterFS磁盘

1
2
# gluster volume stop   models   先停止
# gluster volume delete models   再删除




卸载GlusterFS磁盘

1
gluster peer detach glusterfs4




ACL访问控制

1
gluster volume set models auth.allow 10.60.1.*,10.70.1.*




添加GlusterFS节点

3
# 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

3
# 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)

1
2
# gluster volume replace-brick models sc2-log1:/usr/local/share/models sc2-log5:/usr/local/share/models commit -force
# gluster volume heal models full
