5.同步镜像服务数据库
#su-s/bin/sh-c"glance-managedb_sync"glance
6.重启服务
#serviceglance-registryrestart #serviceglance-apirestart #serviceglance-registrystatus #serviceglance-apistatus
7.验证操作
使用 CirrOS 对镜像服务进行验证
CirrOS是一个小型的Linux镜像，可以用来进行 OpenStack部署测试。
#.admin-openrc
b.下载源镜像
#wgethttp://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img
c.使用 QCOW2 磁盘格式， bare 容器格式上传镜像到镜像服务并设置公共可见
#openstackimagecreate"cirros"\ --filecirros-0.3.5-x86_64-disk.img\ --disk-formatqcow2--container-formatbare\ --public +------------------+------------------------------------------------------+ |Field|Value| +------------------+------------------------------------------------------+ |checksum|f8ab98ff5e73ebab884d80c9dc9c7290| |container_format|bare| |created_at|2017-03-29T05:57:56Z| |disk_format|qcow2| |file|/v2/images/4b6ebd57-80ab-4b79-8ecc-53a026f3e898/file| |id|4b6ebd57-80ab-4b79-8ecc-53a026f3e898| |min_disk|0| |min_ram|0| |name|cirros| |owner|2461396f6a344c21a2360a612d4f6abe| |protected|False| |schema|/v2/schemas/image| |size|13267968| |status|active| |tags|| |updated_at|2017-03-29T05:57:56Z| |virtual_size|None| |visibility|public| +------------------+------------------------------------------------------+

注:Linuxbridge代理只支持VXLAN覆盖网络
d.配置Linuxbridge代理
Linuxbridge代理为实例建立layer－2虚拟网络并且处理安全组规则
#vim/etc/neutron/plugins/ml2/linuxbridge_agent.ini [linux_bridge]----对应公共虚拟网络和公共物理网络接口 physical_interface_mappings=provider:ens33 [vxlan]----启用VXLAN覆盖网络，配置覆盖网络的物理网络接口的IP地址，并启用layer－2population enable_vxlan=true local_ip=192.168.30.145 l2_population=true [securitygroup]----启用安全组并配置防火墙服务 enable_security_group=true firewall_driver=neutron.agent.linux.iptables_firewall.IptablesFirewallDriver #grep^[a-z]/etc/neutron/plugins/ml2/linuxbridge_agent.ini physical_interface_mappings=provider:ens33 firewall_driver=neutron.agent.linux.iptables_firewall.IptablesFirewallDriver enable_security_group=true enable_vxlan=true local_ip=192.168.30.145 l2_population=true
e.配置layer－3代理
Layer-3代理为私有虚拟网络提供路由和NAT服务

f.配置DHCP代理
DHCP代理为虚拟网络提供DHCP服务
#vim/etc/neutron/dhcp_agent.ini [DEFAULT]----配置Linuxbridge驱动接口，DHCP驱动并启用隔离元数据 interface_driver=linuxbridge dhcp_driver=neutron.agent.linux.dhcp.Dnsmasq enable_isolated_Metadata=true #grep^[a-z]/etc/neutron/dhcp_agent.ini interface_driver=linuxbridge dhcp_driver=neutron.agent.linux.dhcp.Dnsmasq enable_isolated_Metadata=true
g.配置元数据代理----负责提供配置信息
#vim/etc/neutron/Metadata_agent.ini [DEFAULT]----配置元数据主机以及共享密码 nova_Metadata_ip=192.168.30.145 Metadata_proxy_shared_secret=qaz123 #grep^[a-z]/etc/neutron/Metadata_agent.ini nova_Metadata_ip=192.168.30.145 Metadata_proxy_shared_secret=qaz123
5.在控制节点上为计算节点配置网络服务
#vim/etc/nova/nova.conf [neutron]----配置访问参数，启用元数据代理并设置密码 url=http://192.168.30.145:9696 auth_url=http://192.168.30.145:35357 auth_type=password project_domain_name=default user_domain_name=default region_name=RegionOne project_name=service username=neutron password=neutron service_Metadata_proxy=true Metadata_proxy_shared_secret=qaz123 #grep^[a-z]/etc/nova/nova.conf
6.完成安装
a.同步数据库
#su-s/bin/sh-c"neutron-db-manage--config-file/etc/neutron/neutron.conf\\ --config-file/etc/neutron/plugins/ml2/ml2_conf.iniupgradehead"neutron ...... OK
注:数据库的同步发生在 Networking 之后，因为脚本需要完成服务器和插件的配置文件
b.重启计算 API 服务
#servicenova-apirestart
c.重启 Networking 服务
对于两种网络类型:
#serviceneutron-serverrestart #serviceneutron-linuxbridge-agentrestart #serviceneutron-dhcp-agentrestart #serviceneutron-Metadata-agentrestart
对于网络类型 2 ，还需重启 L3 服务:
#serviceneutron-l3-agentrestart
d.确认启动与否
#servicenova-apistatus #serviceneutron-serverstatus #serviceneutron-linuxbridge-agentstatus #serviceneutron-dhcp-agentstatus #serviceneutron-Metadata-agentstatus #serviceneutron-l3-agentstatus
7.配置 Compute Node 的Neutron 网络服务
#apt-yinstallneutron-linuxbridge-agent #vim/etc/neutron/neutron.conf [database]----计算节点不直接访问数据库 #connection=sqlite:////var/lib/neutron/neutron.sqlite [DEFAULT]----配置RabbitMQ消息队列访问[用户名:密码@控制节点] transport_url=rabbit://openstack:openstack@192.168.30.145 [DEFAULT]----配置认证服务访问 auth_strategy=keystone [keystone_authtoken]----配置认证服务访问 auth_uri=http://192.168.30.145:5000 auth_url=http://192.168.30.145:35357 memcached_servers=192.168.30.145:11211 auth_type=password project_domain_name=default user_domain_name=default project_name=service username=neutron password=neutron #grep^[a-z]/etc/neutron/neutron.conf auth_strategy=keystone core_plugin=ml2 transport_url=rabbit://openstack:openstack@192.168.30.145 root_helper=sudo/usr/bin/neutron-rootwrap/etc/neutron/rootwrap.conf auth_uri=http://192.168.30.145:5000 auth_url=http://192.168.30.145:35357 memcached_servers=192.168.30.145:11211 auth_type=password project_domain_name=default user_domain_name=default project_name=service username=neutron password=neutron
8.为计算节点配置网络服务
#vim/etc/nova/nova.conf [neutron]----配置访问参数 url=http://192.168.30.145:9696 auth_url=http://192.168.30.145:35357 auth_type=password project_domain_name=default user_domain_name=default region_name=RegionOne project_name=service username=neutron password=neutron #grep^[a-z]/etc/nova/nova.conf
