声明：最近在进行openstack的kilo版本的安装，发现现有的网络教程非常少，而且多数教程并不能安装成功，故写此教程。openstack的安装较为复杂，本教程并不能保证在不同环境下也能将其安装成功。个人安装教程，也难免出错。同时，安装是在虚拟机环境下，真实安装环境需要进行更改。

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
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
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
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。
注：以后的博客中会对安装过程中遇到的问题进行相关总结。
