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

//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

--config-
file
/etc/neutron/plugins/ml2/ml2_conf
.ini upgrade
head
" 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
# service nova-api restart
c.重启 Networking 服务
对于两种网络类型:
# service neutron-server restart
# service neutron-linuxbridge-agent restart
# service neutron-dhcp-agent restart
# service neutron-metadata-agent restart
对于网络类型 2 ，还需重启 L3 服务:
# service neutron-l3-agent restart
d.确认启动与否
# service nova-api status
# service neutron-server status
# service neutron-linuxbridge-agent status
# service neutron-dhcp-agent status
# service neutron-metadata-agent status
# service neutron-l3-agent status
