enable_vxlan = false
  • 在?``[securitygroup]``部分，啟用安全組并配置 Linuxbridge?iptables?firewall driver:
[securitygroup]
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
  • 通過驗證以下所有sysct1值都設(shè)置為，確保您的 Linux 操作系統(tǒng)內(nèi)核支持網(wǎng)橋過濾器1，修改文件?

[neutron]
url = http://controller:9696
auth_url = http://controller:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = neutronservice_metadata_proxy = True
metadata_proxy_shared_secret = hao123

11.安裝完成

  • 網(wǎng)絡(luò)服務(wù)初始化腳本需要一個超鏈接?/etc/neutron/plugin.ini``指向ML2插件配置文件/etc/neutron/plugins/ml2/ml2_conf.ini``。如果超鏈接不存在，使用下面的命令創(chuàng)建它：
ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
  • ?同步數(shù)據(jù)庫：
su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf \--config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron
  • ?重啟計算API 服務(wù)：
systemctl restart openstack-nova-api.service
  • 當(dāng)系統(tǒng)啟動時，啟動 Networking 服務(wù)并配置它啟動。
systemctl enable neutron-server.service \neutron-linuxbridge-agent.service neutron-dhcp-agent.service \neutron-metadata-agent.service
systemctl start neutron-server.service \neutron-linuxbridge-agent.service neutron-dhcp-agent.service \neutron-metadata-agent.service

memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = neutron
  • ?在?[oslo_concurrency]?部分，配置鎖路徑：
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp

13.配置Linuxbridge代理

  • 編輯``/etc/neutron/plugins/ml2/linuxbridge_agent.ini``文件并且完成以下操作：?
[linux_bridge]
physical_interface_mappings = extnet:ens33
  • ?在``[vxlan]``部分，禁止VXLAN覆蓋網(wǎng)絡(luò)：
[vxlan]
enable_vxlan = false
  • 在?``[securitygroup]``部分，啟用安全組并配置 Linuxbridge?iptables?firewall driver:
[securitygroup]
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
  • ?修改/etc/sysctl.conf文件
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1

14.為計算節(jié)點配置網(wǎng)絡(luò)服務(wù)

  • 編輯``/etc/nova/nova.conf``文件并完成下面的操作：?
[neutron]
auth_url = http://controller:5000
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron

14.完成安裝

  • 重啟計算服務(wù)：
systemctl restart openstack-nova-compute.service
  • 啟動Linuxbridge代理并配置它開機(jī)自啟動：
systemctl enable neutron-linuxbridge-agent.service
systemctl start neutron-linuxbridge-agent.service

15.驗證

openstack extension list --network

neutron部署完成?

  • Neutron網(wǎng)絡(luò)結(jié)構(gòu)圖，管理員創(chuàng)建和管理Neutron外部網(wǎng)絡(luò)，是租戶虛擬機(jī)與互聯(lián)網(wǎng)信息交互的橋梁。更具體的，外部網(wǎng)絡(luò)會分出一個子網(wǎng)，它是一組在互聯(lián)網(wǎng)上可尋址的IP地址。一般情況下，外部網(wǎng)絡(luò)只有一個（neutron是支持多個外部網(wǎng)絡(luò)的），且由管理員創(chuàng)建。租戶虛擬機(jī)創(chuàng)建和管理租戶網(wǎng)絡(luò)，每個網(wǎng)絡(luò)可以根據(jù)需要劃分成多個子網(wǎng)。諸多子網(wǎng)通過路由器與Neutron外部網(wǎng)絡(luò)(圖中具體是子網(wǎng)A)連接。路由器的gateway網(wǎng)關(guān)端連接外部網(wǎng)絡(luò)的子網(wǎng)，interfaces接口端有多個，連接租戶網(wǎng)絡(luò)的子網(wǎng)。路由器及interface接口端連接的網(wǎng)絡(luò)都是由租戶根據(jù)需要自助創(chuàng)建，管理者只創(chuàng)建和管理Neutron外部網(wǎng)絡(luò)部分。

總結(jié)來看，創(chuàng)建一個Neutron網(wǎng)絡(luò)的過程如下：

? ? ? ?1 、首先管理員拿到一組可以在互聯(lián)網(wǎng)上尋址的IP地址，并且創(chuàng)建一個外部網(wǎng)絡(luò)和子網(wǎng)

? ? ? ?2、 租戶創(chuàng)建一個網(wǎng)絡(luò)和子網(wǎng)

? ? ? ?3、 租戶創(chuàng)建一個路由器并且連接租戶子網(wǎng)和外部網(wǎng)絡(luò)

? ? ? ?4、 租戶創(chuàng)建虛擬機(jī)
