sed -i 's/false/true/g' /etc/default/iscsitarget
重启服务：
service iscsitarget start service open-iscsi start
配置/etc/cinder/api-paste.ini
filter:authtoken] paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory service_protocol = http service_host = 192.168.0.51 service_port = 5000 auth_host = 10.10.10.51 auth_port = 35357 auth_protocol = http admin_tenant_name = service admin_user = cinder admin_password = service_pass
编辑/etc/cinder/cinder.conf
[DEFAULT] rootwrap_config=/etc/cinder/rootwrap.conf sql_connection = mysql://cinderUser:cinderPass@10.10.10.51/cinder api_paste_config = /etc/cinder/api-paste.ini iscsi_helper=ietadm volume_name_template = volume-%s volume_group = cinder-volumes verbose = True auth_strategy = keystone #osapi_volume_listen_port=5900
接下来同步数据库：
cinder-manage db sync
最后别忘记创建一个卷组命名为cinder-volumes:
dd if=/dev/zero of=cinder-volumes bs=1 count=0 seek=2G losetup /dev/loop2 cinder-volumes fdisk /dev/loop2 #Type in the followings: n p 1 ENTER ENTER t 8e w
创建物理卷和卷组：
pvcreate /dev/loop2 vgcreate cinder-volumes /dev/loop2
注意：重启后卷组不会自动挂载，如下进行设置：
vim /etc/init/losetup.conf description "set up loop devices" start on mounted MOUNTPOINT=/ task exec /sbin/losetup /dev/loop0 /dev/cinder-volumes
重启cinder服务：
cd /etc/init.d/; for i in $( ls cinder-* ); do service $i restart; done
确认Cinder服务在运行：
cd /etc/init.d/; for i in $( ls cinder-* ); do service $i status; done
2.11.设置Horizon
安装horizon：
apt-get install openstack-dashboard memcached
如果你不喜欢OpenStack ubuntu主题，你可以停用它：
dpkg --purge openstack-dashboard-ubuntu-theme
重启Apache和memcached服务：
service apache2 restart; service memcached restart
注意：重启apache2,出现could not reliably determine the server's fully domain name,using 127.0.0.1 for ServerName.这是由于没有解析出域名导致的。解决方法如下：编辑/etc/apache2/httpd.conf，添加如下操作即可。
ServerName localhost
2.12.设置Ceilometer
安装Metering服务
apt-get install ceilometer-api ceilometer-collector ceilometer-agent-central python-ceilometerclient
安装MongoDB数据库
apt-get install mongodb
配置mongodb监听所有网络接口请求：
sed -i 's/127.0.0.1/0.0.0.0/g' /etc/mongodb.conf service mongodb restart
创建ceilometer数据库用户：
#mongo
>use ceilometer
>db.addUser({ user:"ceilometer",pwd:"CEILOMETER_DBPASS",roles:["readWrite","dbAdmin"]})配置Metering服务使用数据库
... [database] ... # The SQLAlchemy connection string used to connect to the # database (string value) connection = mongodb://ceilometer:CEILOMETER_DBPASS@10.10.10.51:27017/ceilometer ...
配置RabbitMQ访问,编辑/etc/ceilometer/ceilometer.conf
... [DEFAULT] rabbit_host = 10.10.10.51
编辑/etc/ceilometer/ceilometer.conf使认证信息生效
[keystone_authtoken] auth_host = 10.10.10.51 auth_port = 35357 auth_protocol = http admin_tenant_name = service admin_user = ceilometer admin_password = CEILOMETER_PASS
简单获取镜像，你必须配置镜像服务以发送通知给总线，编辑/etc/glance/glance-api.conf修改[DEFAULT]部分
notifier_strategy=rabbit rabbit_host=10.10.10.51
重启镜像服务
cd /etc/init.d/;for i in $(ls glance-* );do service $i restart;done
重启服务，使配置信息生效
cd /etc/init.d;for i in $( ls ceilometer-* );do service $i restart;done
编辑/etc/cinder/cinder.conf，获取volume。
control_exchange=cinder notification_driver=cinder.openstack.common.notifier.rpc_notifier
重启Cinder服务
cd /etc/init.d/;for i in $( ls cinder-* );do service $i restart;done

5.创建第一VM
5.1.为admin租户创建内网、外网、路由器和虚拟机设置环境变量：
vim creds-admin #Paste the following: export OS_TENANT_NAME=admin export OS_USERNAME=admin export OS_PASSWORD=admin_pass export OS_AUTH_URL="http://192.168.100.51:5000/v2.0/" source creds-admin
列出已创建的用户和租户：
keystone user-list keystone tenant-list
为admin租户创建网络：
neutron net-create --tenant-id $id_of_tenant --router:external=True net_admin
为admin租户创建子网：
neutron subnet-create --tenant-id $id_of_tenant net_admin 50.50.50.0/24
为admin租户创建路由器：
neutron router-create --tenant-id $id_of_tenant router_admin
列出路由代理类型：
neutron agent-list
将router_admin设置为L3代理类型：
neutron l3-agent-router-add $id_of_l3_agent router_admin Added router router_admin to L3 agent
将net_admin子网与router_admin路由关联：
neutron router-interface-add $id_of_router_admin $id_of_net_admin
创建外网net_external，注意设置--router:external=True：
neutron net-create net_external --router:external=True --shared
为net_admin创建子网，注意设置的gateway必须在给到的网段内：
neutron subnet-create --tenant-id $id_of_tenant --allocation-pool start=192.168.100.102,end=192.168.100.130 --gateway=192.168.100.1 net_external 192.168.100.0/24 --enable_dhcp=False
将net_external与router_admin路由器关联：
neutron router-gateway-set router_admin net_external Set gateway for router router_admin
创建floating ip:
neutron floatingip-create net_external
neutron floatingip-create net_external
6.参考文档：
1.openstack官方文档：http://docs.openstack.org/havana/install-guide/install/apt/openstack-install-guide-apt-havana.pdf目前openstack官方文档已经做的很好了，如何安装，配置，写的都挺不错的，还有neutron那一节对各种情况的网络结构列出的很详细。
