openstack安装笔记 Cinder(三)

问题，怎么在一个操作后，看系统中多了和修改了哪些内容

yum源配置参考前两篇

yum install openstack-cinder openstack-utils python-kombu python-amqplib

source  /root/keystone_admin
内容为
cat  /root/keystone_admin
export OS_USERNAME=admin
export OS_TENANT_NAME=admin
export OS_PASSWORD=openstack
export OS_AUTH_URL=http://172.16.21.233:35357/v2.0/
export PS1='[\u@\h \W(keystone_admin)]\$ '

在keystone中加service

 keystone service-create --name cinder  --type volume --description "Cinder Volume Service hao"
WARNING: Bypassing authentication using a token & endpoint (authentication credentials are being ignored).
+-------------+----------------------------------+
|   Property  |              Value               |
+-------------+----------------------------------+
| description |    Cinder Volume Service hao     |
|      id     | 97dd83f58ab949ba88d543b26665b564 |
|     name    |              cinder              |
|     type    |              volume              |
+-------------+----------------------------------+

在keystone库中加了一条数据

keystone endpoint-create --service-id  cinder --publicurl "http://172.16.21.233:8776/v1/\$(tenant_id)s" --adminurl "http://172.16.21.233:8776/v1/\$(tenant_id)s" --internalurl "http://172.16.21.233:8776/v1/\$(tenant_id)s" --region beijing

+-------------+--------------------------------------------+
[root@controller ~(keystone_admin)]# 

keystone库的endpoint表加了三条数据

vmware iscs硬盘新建个10G的
然后

pvcreate  /dev/sdb  
vgcreate vgstorage /dev/sdb
vgs
lvs

修改Cinder的配置文件，在配置文件里面指定了keystone的设置，cinder采用的逻辑卷的名称vgstorage，和指定了cinder服务器的ip地址
cp /etc/cinder/cinder.conf cinder.conf
修改后vimdiff观察修改，每个操作启示就是在default下面多了一行

openstack-config --set /etc/cinder/cinder.conf  DEFAULT auth_strategy keystone
openstack-config --set /etc/cinder/cinder.conf DEFAULT sql_connection   mysql://cinder:[email protected]/cinder
openstack-config --set /etc/cinder/cinder.conf DEFAULT volume_group vgstorage
openstack-config --set /etc/cinder/cinder.conf DEFAULT volume_driver cinder.volume.drivers.lvm.LVMISCSIDriver
openstack-config --set /etc/cinder/cinder.conf DEFAULT rpc_backend cinder.openstack.common.rpc.impl_kombu
openstack-config --set /etc/cinder/cinder.conf DEFAULT my_ip 172.16.21.233
openstack-config --set /etc/cinder/cinder.conf DEFAULT rabbit_host  172.16.21.233
openstack-config --set /etc/cinder/cinder.conf  keystone_authtoken auth_host 172.16.21.233
openstack-config --set /etc/cinder/cinder.conf  keystone_authtoken admin_tenant_name admin
openstack-config --set /etc/cinder/cinder.conf  keystone_authtoken admin_user admin 
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_password openstack

cinde.conf多了如下

 [DEFAULT]                                                
  auth_strategy = keystone                                 
  sql_connection = mysql://cinder:[email protected]/cinder
  volume_group = vgstorage  
  volume_driver = cinder.volume.drivers.lvm.LVMISCSIDriver
  rpc_backend = cinder.openstack.common.rpc.impl_kombu    
  my_ip = 172.16.21.233                                    
  rabbit_host = 172.16.21.233 

[keystone_authtoken]                                     
  auth_host = 172.16.21.233                             
  admin_tenant_name = admin                          
  admin_user = admin                                     
  admin_password = openstack 

创建cinder数据库

openstack-db --init --service cinder --password cinder --rootpw openstack

migrate_version表默认有一条数据
quota_classes表会有默认三条数据
volumes snapshots gigabytes

修改权限

chown -R cinder:cinder /etc/cinder
chown -R cinder:cinder /var/lib/cinder
chown -R cinder:cinder /var/log/cinder

配置iSCSI服务，配合Cinder，将Cinder创建的逻辑卷通过iscsi挂载给虚拟机
vi /etc/tgt/targets.conf，添加一行：

 include /etc/cinder/volumes/*

• 设置tgtd服务开机自启动，并启动tgtd服务

chkconfig tgtd on
service tgtd start

• 设置Cinder服务开机自启动，并启动Cinder服务

chkconfig  openstack-cinder-api on
chkconfig openstack-cinder-scheduler on
chkconfig openstack-cinder-volume on

service openstack-cinder-api start
service openstack-cinder-scheduler start
service openstack-cinder-volume start

当将该卷绑定到VM上面后可以查看：
tgtadm --lld iscsi --op show --mode target 
???? 怎么绑定？
