云主机基本环境&Keystone 和 云主机Cinder
云主机基本环境&Keystone 和 云主机Cinder是样题中“任务三、IaaS运维 ”中的单主机Keystone+Cinder配置。
首先应能够运行云主机，正常获取IP地址，配置安全组启用SSH，确认三层交换机上实现管理和外网两个网段之间的路由互通，才可以做这部分内容。
单独一台云主机
3、块存储服务Cinder
（1）配置Cinder控制服务
yum install openstack-cinder
openstack-config --set /etc/cinder/cinder.conf database connection mysql://cinder:000000@controller/cinder
su -s /bin/sh -c "cinder-manage db sync" cinder
source admin-openrc.sh
keystone user-create --name=cinder --pass=000000 --email=cinder@localhost
keystone user-role-add --user=cinder --tenant=service --role=admin
openstack-config --set /etc/cinder/cinder.conf DEFAULT auth_strategy keystone
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_uri http://controller:5000
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_host controller
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_protocol http
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_port 35357
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_user cinder
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_tenant_name service
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_password 000000
openstack-config --set /etc/cinder/cinder.conf DEFAULT rpc_backend qpid
openstack-config --set /etc/cinder/cinder.conf DEFAULT qpid_hostname controller
keystone service-create --name=cinder --type=volume --description="OpenStack Block Storage"
keystone endpoint-create \
--service-id=$(keystone service-list | awk '/ volume / {print $2}') \
--publicurl=http://controller:8776/v1/%\(tenant_id\)s \
--internalurl=http://controller:8776/v1/%\(tenant_id\)s \
--adminurl=http://controller:8776/v1/%\(tenant_id\)s
keystone service-create --name=cinderv2 --type=volumev2 --description="OpenStack Block Storage v2"
keystone endpoint-create \
--service-id=$(keystone service-list | awk '/ volumev2 / {print $2}') \
--publicurl=http://controller:8776/v2/%\(tenant_id\)s \
--internalurl=http://controller:8776/v2/%\(tenant_id\)s \
--adminurl=http://controller:8776/v2/%\(tenant_id\)s
service openstack-cinder-api start
service openstack-cinder-scheduler start
chkconfig openstack-cinder-api on
chkconfig openstack-cinder-scheduler on
（2）配置Cinder存储服务
使用fdisk对磁盘分区，创建一个LVM类型分区，在本案例中将使用/dev/sda3。
（注意：云主机中的磁盘名称为vda）
fdisk /dev/vda
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').
Command (m for help): p # 显示当前分区
Disk /dev/sda: 107.4 GB, 107374182400 bytes

Command (m for help): w # 保存退出
partx -a /dev/vda
pvcreate /dev/vda3
vgcreate cinder-volumes /dev/vda3
vi /etc/lvm/lvm.conf，在devices部分配置LVM将持续扫描的虚拟机实例所使用的设备。
devices {
...
filter = [ "a/vda2/", "a/vda3/", "r/.*/"] # 添加这一行
...
}
其中vda2为操作系统所在的物理卷设备，vda3为cinder卷所使用的物理卷设备。
yum install scsi-target-utils
openstack-config --set /etc/cinder/cinder.conf DEFAULT my_ip 云主机IP
openstack-config --set /etc/cinder/cinder.conf DEFAULT glance_host controller
openstack-config --set /etc/cinder/cinder.conf DEFAULT iscsi_helper tgtadm
vi /etc/tgt/targets.conf
include /etc/cinder/volumes/*
service openstack-cinder-volume start
service tgtd start
chkconfig openstack-cinder-volume on
chkconfig tgtd on
（3）使用cinder命令管理云硬盘
cd
source admin-openrc.sh
使用cinder create创建云硬盘，指定名称为cinder-disk，大小为1GB。
# cinder create --display-name cinder-disk 1

+--------------------------------------+-----------+--------------+------+-------------+----------+-------------+
将云硬盘cinder-disk扩展为2GB。
# cinder extend cinder-disk 2
显示云硬盘的状态
# cinder list

+--------------------------------------+-----------+--------------+------+-------------+----------+-------------+
删除云硬盘
# cinder delete cinder-disk
