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

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

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/
