聲明：最近在進行openstack的kilo版本的安裝，發現現有的網絡教程非常少，而且多數教程並不能安裝成功，故寫此教程。openstack的安裝較為復雜，本教程並不能保證在不同環境下也能將其安裝成功。個人安裝教程，也難免出錯。同時，安裝是在虛擬機環境下，真實安裝環境需要進行更改。

第五部分
neutron的安裝 （3）
在計算節點上的安裝
進行配置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
執行
sysctl -p
安裝包
yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch
進行相關配置文件的修改vim /etc/neutron/neutron.conf
rpc_backend=rabbit 去掉#號
rabbit_host = controller
rabbit_userid=openstack
rabbit_password =openstack
auth_strategy = keystone 去掉#號
在標簽[keystone_authtoken]
修改以下內容：
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 #替換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
添加以下內容（如果沒有）
[ovs]
local_ip = INSTANCE_TUNNELS_INTERFACE_IP_ADDRESS
[agent]
tunnel_types = gre
啟動
systemctl enable openvswitch.service
systemctl start openvswitch.service
進行相關配置
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]標簽下
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 #替換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
重新啟動
systemctl restart openstack-nova-compute.service
systemctl enable neutron-openvswitch-agent.service
systemctl start neutron-openvswitch-agent.service
----------------------------------------------------------------------------------------------------------------------
在控制節點上（測試）
source admin-openrc.sh
neutorn agent-list
如果正常，就可以創建初始網絡了。
此教程完。注：以後的博客中會對安裝過程中遇到的問題進行相關總結。
