openstack安装配置—— block node配置
对于云主机来说，机器可以随时销毁再创建，但数据一定不能，所以就需要数据的持久存储，openstack官方给出的数据存储方案就是cinder模块，cinder模块需要cinder服务端和cinder存储节点共同构成，在本实验中，我们把cinder服务端一并安装在了controller节点上，另行配置一台cinder存储节点，也就是我们的block节点。block节点基础配置

#
修改compute节点配置，以使compute节点能够支持cinder模块
编辑文件 /etc/nova/nova.conf 并添加如下到其中
# vim /etc/nova/nova.conf
os_region_name = RegionOne
重启计算节点的nova服务
# systemctl restart openstack-nova-compute
重启controller端的nova服务
# systemctl restart openstack-nova-api.service
启用并启动cinder服务
# systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-cinder-api.service to /usr/lib/systemd/system/openstack-cinder-api.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-cinder-scheduler.service to /usr/lib/systemd/system/openstack-cinder-scheduler.service.
# systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service
# ss -tnl//启动cinder服务后会新增8776端口

cinder存储节点配置
kvm宿主机上的操作
给块存储节点添加一块硬盘，先将block节点关机，然后前往kvm控制台进行操作添加虚拟磁盘
# qemu-img create -q -f qcow2 /kvm/images/block_lvm.qcow2 100G
# ll -h /kvm/images/block_lvm.qcow2
-rw-r--r-- 1 root root 194K Jul 25 00:49 /kvm/images/block_lvm.qcow2
# virsh edit block
在原有配置段下面添加如下配置
</disk>
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/kvm/images/block_lvm.qcow2'/>
<target dev='vdb' bus='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x10' function='0x0'/>
</disk>
修改完成后保存退出，启动block虚机
block节点上继续操作

block节点在实际生产环境中也数量庞大的，所以也需要在成功配置一个节点后写成自动化配置脚本，以便大批量部署。
