在计算节点上的安装

进行配置

vim /etc/sysctl.conf

net.ipv4.conf.all.rp_filter=0
net.ipv4.conf.default.rp_filter=0
net.bridge.bridge-nf-call-iptables=1
net.bridge.bridge-nf-call-ip6tables=1

执行

sysctl -p

安装包

yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch

进行相关配置文件的修改

vim /etc/neutron/neutron.conf

rpc_backend=rabbit 去掉#号
rabbit_host = controller
rabbit_userid=openstack
rabbit_password =openstack
 
auth_strategy = keystone 去掉#号
在标签[keystone_authtoken]
修改以下内容：
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = neutron
password = neutron #替换NEUTRON_PASS
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = True
[default]
verbose  = True

vim /etc/neutron/plugins/ml2/ml2_conf.ini

type_drivers = flat,vlan,gre,vxlan
tenant_network_types = gre
mechanism_drivers = openvswitch
tunnel_id_ranges=1:1000
 
 
enable_security_group = True
enable_ipset = True
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
添加以下内容（如果没有）
 
[ovs]
local_ip = INSTANCE_TUNNELS_INTERFACE_IP_ADDRESS
 
[agent]
tunnel_types = gre

启动

systemctl enable openvswitch.service
systemctl start openvswitch.service

进行相关配置

vim //etc/nova/nova.conf

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[neutorn]标签下
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 #替换NEUTRON_PASS
 
auth_strategy=keystone

ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

cp /usr/lib/systemd/system/neutron-openvswitch-agent.service /usr/lib/systemd/system/neutron-openvswitch-agent.service.orig

 sed -i 's,plugins/openvswitch/ovs_neutron_plugin.ini,plugin.ini,g' /usr/lib/systemd/system/neutron-openvswitch-agent.service

重新启动

systemctl restart openstack-nova-compute.service
systemctl enable neutron-openvswitch-agent.service
systemctl start neutron-openvswitch-agent.service

在控制节点上（测试）

source admin-openrc.sh
neutorn agent-list

如果正常，就可以创建初始网络了。

此教程完。
