OpenStact之cinder

news 来源：原创 2024/5/4 17:27:35

3.6、Add the Block Storage service(Cinder)

Cinder:主要包括cinder api、cider-volume、cider-scheduler deamon、Messaging queue

cinder-api:接受API请求并将请求路由到cinder-volume来执行

cinder-volume: 响应请求，读取或写向块存储数据库为维护状态，通过信息队列机制与其他进程交互(cinder-scheduler),或直接与上层块存储提供的硬件或软件进行交互。通过驱动结构，它可以与众多的存储提供者交互

cinder-scheduler: 守护进程。类似于Nova-scheduler，为存储的实例选取最优的块存储供应节点

[root@linux-node1 ~]# yum install -y openstack-cinder python-cinderclient

[root@linux-node1 ~]# vim /etc/cinder/cinder.conf

connection=mysql://cinder:cinder@10.0.0.101/cinder

[root@linux-node1 ~]# cinder-manage db sync

[root@linux-node1 ~]# mysql -h 10.0.0.101 -u cinder -pcinder -e "use cinder;show tables;"

3.6.1、关闭计算节点(linux-node2)，在上面添加一块20G硬盘

[root@linux-node2 ~]# pvcreate /dev/sdb

Physical volume "/dev/sdb" successfully created

[root@linux-node2 ~]# vgcreate cinder-volumes /dev/sdb

Volume group "cinder-volume" successfully created

[root@linux-node2 ~]# vim /etc/lvm/lvm.conf

filter = [ "a/sda1/", "a/sdb/","r/.*/" ]

[root@linux-node2 ~]# yum install -y scsi-target-utils

[root@linux-node2 ~]# vim /etc/tgt/targets.conf

include /etc/cinder/volumes/*

[root@linux-node2 ~]# /etc/init.d/tgtd start

Starting SCSI target daemon: [ OK ]

[root@linux-node2 ~]# chkconfig tgtd on

[root@linux-node2 ~]# yum install -y openstack-cinder

在linux-node1上把cinder的配置文件scp到linux-node2上

[root@linux-node1 ~]# scp /etc/cinder/cinder.conf root@10.0.0.102:/etc/cinder/

[root@linux-node2 ~]# vim /etc/cinder/cinder.conf

3.6.2、登录demo账户，创建云硬盘

[root@linux-node2 ~]# lvdisplay ##验证创建的云盘

3.6.3、把云硬盘(test)挂载到以前创建的云主机(demo)上，云主机(demo)应是active状态

用Xshell远程连接云主机(进入云主机，得知ip为10.0.0.32)

$ sudo fdisk -l

$ sudo mkdir /data1 ##创建目录

$ sudo mount /dev/vdb1 /data1 ##挂载云硬盘

$ cd /data1/

$ ls

$ cd

$ pwd

/home/cirros

$ sudo umount /dev/vdb1 ##离开/data1目录，卸载云硬盘，就可以把云硬盘和云主机断开

3.6.4、为云硬盘创建类型

[root@linux-node1 ~]# source keystone-admin

[root@linux-node1 ~]# cinder type-create iSCSI

[root@linux-node1 ~]# cinder type-key iSCSI set volume_backend_name=iSCSI-Storage

3.6.4.1、创建一个类型为iSCSI的云硬盘

3.6.4.2、创建一个类型为NFS的云硬盘
