在[database]
部分,注释掉connection选项,由于compute节点不须要直接访问数据库。app
在[DEFAULT]
部分,设定RabbitMQ的访问选项:
<pre>[DEFAULT]
</pre>
...
rpc_backend = rabbit
rabbit_host = controller
rabbit_password = RABBIT_PASS
RABBIT_PASS为RabbitMQ guest帐户的密码。ide
在[DEFAULT]
和[keystone_authtoken]
部分,设定认证服务的访问选项:
<pre>[DEFAULT]
</pre>
...
auth_strategy = keystone
<pre>[keystone_authtoken]
</pre>
...
auth_uri = http://controller:5000/v2.0
identity_uri = http://controller:35357
admin_tenant_name = service
admin_user = neutron
admin_password = NEUTRON_PASS
NEUTRON_PASS为建立neutron用户时使用的密码。在[keystone_authtoken]部分,注释掉 auth_host,auth_port,和auth_protocol的选项,由于identity_uri选项是直接代替它们的。oop
在[DEFAULT]
部分,开启Modular Layer 2(ML2)plug-in选项,设定router service和overlapping IP addresses选项:
<pre>[DEFAULT]
</pre>url
...
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = True
在[DEFAULT]
部分,开启“详细输出日志”选项:
<pre>[DEFAULT]
</pre>.net
...
verbose = True
编辑# vi /etc/neutron/plugins/ml2/ml2_conf.ini
文件:3d
在[ml2]
部分,启用flat和generic routing encapsulation(GRE)网络类型的驱动( network type drivers),GRE 租户网络和OVS机制的驱动:
<pre>[ml2]
</pre>
...
type_drivers = flat,gre
tenant_network_types = gre
mechanism_drivers = openvswitch
在[ml2_type_gre]
部分,设定tunnel ID范围:
<pre>[ml2_type_gre]
</pre>
...
tunnel_id_ranges = 1:1000
在[securitygroup]
部分,启用security groups,ipset, and configure,设定OVS iptables firewall driver:
<pre>[securitygroup]
</pre>
...
enable_security_group = True
enable_ipset = True
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
在[ovs]
部分,启用tunnel,设定local tunnel endpoint,把external flat provider network和br-ex external network brigde绑定起来:
<pre>[ovs]
</pre>
...
local_ip = INSTANCE_TUNNELS_INTERFACE_IP_ADDRESS
enable_tunneling = True
bridge_mappings = external:br-ex
INSTANCE_TUNNELS_INTERFACE_IP_ADDRESS为network节点在tunnel network中的IP地址。
在[agent]
部分,启用GRE tunnels:
<pre>[agent]
</pre>
...
tunnel_types = gre
重启OVS服务:# service openvswitch-switch restart
编辑# vi /etc/nova/nova.conf
文件:
在[DEFAULT]
部分,设定API和驱动:
<pre>[DEFAULT]
</pre>
...
network_api_class = nova.network.neutronv2.api.API
security_group_api = neutron
linuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriver
firewall_driver = nova.virt.firewall.NoopFirewallDriver
在[neutron]
部分,设定访问参数:
<pre>[neutron]
</pre>
...
url = http://controller:9696
auth_strategy = keystone
admin_auth_url = http://controller:35357/v2.0
admin_tenant_name = service
admin_username = neutron
admin_password = NEUTRON_PASS
NEUTRON_PASS为建立neutron用户时使用的密码。
# service nova-compute restart
# service neutron-plugin-openvswitch-agent restart
