篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了openstack Q版部署-----网络服务(neutron)安装部署相关的知识,希望对你有一定的参考价值。

一、数据库配置

控制节点创建数据库

CREATE DATABASE neutron;
GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron‘@‘localhost‘ IDENTIFIED BY ‘neutron2018‘;
GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron‘@‘%‘ IDENTIFIED BY ‘neutron2018‘;

二、创建认证信息(控制节点)

先生效一下环境变量

创建neutron用户:

openstack user create --domain default --password=neutron neutron #此处密码我设置了neutorn

将neutron加入到admin组和service项目

openstack role add --project service --user neutron admin

创建网络项目:

openstack service create --name neutron --description "OpenStack Networking" network

创建endpoint,将网络服务端口信息注册到认证服务

openstack endpoint create --region RegionOne network public http://10.1.80.110:9696

openstack endpoint create --region RegionOne network internal http://10.1.80.110:9696

openstack endpoint create --region RegionOne network admin http://10.1.80.110:9696

三、安装二层简单网络:

在网络节点执行安装包:

yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge ebtables -y

编辑配置文件:/etc/neutron/neutron.conf

[database]
connection = mysql://neutron:[email protected]/neutron
[DEFAULT]
core_plugin = ml2
service_plugins = router
transport_url = rabbit://openstack:[email protected]
auth_strategy = keystone
notify_nova_on_port_status_changes = true
notify_nova_on_port_data_changes = true
[keystone_authtoken]
auth_uri = http://10.1.80.110:5000
auth_url = http://10.1.80.110:35357
memcached_servers = 10.1.80.110:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = neutron
[nova]
auth_url = http://10.1.80.110:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = nova
password = nova2018
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp

编辑/etc/neutron/plugins/ml2/ml2_conf.ini文件配置二层插件

[ml2]
type_drivers = flat,vlan,gre,vxlan,geneve
tenant_network_types = vlan,gre,vxlan,geneve
mechanism_drivers = linuxbridge
extension_drivers = port_security
[ml2_type_flat]
flat_networks = pyth1##可以自己随便取
[securitygroup]
enable_ipset = true

编辑/etc/neutron/plugins/ml2/linuxbridge_agent.ini文件配置linux bridge插件

[linux_bridge]
physical_interface_mappings = pyth1:ens160 #第二张网卡网卡名
[vxlan]
enable_vxlan = false
[securitygroup]
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

确认内核支持网桥filters并作如下设置,编辑vi /usr/lib/sysctl.d/00-system.conf 修改以下内容

net.bridge.bridge-nf-call-iptables=1
net.bridge.bridge-nf-call-ip6tables=1

sysctl -p

载入br_netfilter模块

modprobe br_netfilter

编辑/etc/neutron/dhcp_agent.ini

[DEFAULT]
interface_driver = linuxbridge
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_metadata = true

编辑/etc/neutron/metadata_agent.ini

[default]
nova_metadata_host = 10.1.80.110
metadata_proxy_shared_secret = neutron

二、在控制节点nova配置neutron
编辑/etc/nova/nova.conf

[neutron]
url = http://10.1.80.112:9696
auth_url = http://10.1.80.110:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron
service_metadata_proxy = true
metadata_proxy_shared_secret = neutron

网络节点执行:

创建连接文件

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

导入数据库结构

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

控制节点:

systemctl restart openstack-nova-api.service

网络节点:

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
systemctl status neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service

四、计算节点安装网络服务

计算节点安装软件包

yum install openstack-neutron-linuxbridge ebtables ipset -y
修改配置文件/etc/neutron/neutron.conf
[DEFAULT]
transport_url = rabbit://openstack:[email protected]
auth_strategy = keystone
[keystone_authtoken]
auth_uri = http://10.1.80.110:5000
auth_url = http://10.1.80.110:35357
memcached_servers = 10.1.80.110:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = neutron
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
修改/etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linux_bridge]
physical_interface_mappings = pyth1:ens160
[vxlan]
enable_vxlan = false
[securitygroup]
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

配置nova 使用neutron,/etc/nova/nova.conf

[neutron]
url = http://10.1.80.112:9696
auth_url = http://10.1.80.110:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron

确认内核支持网桥filters并作如下设置,编辑vi /usr/lib/sysctl.d/00-system.conf 修改以下内容

net.bridge.bridge-nf-call-iptables=1
net.bridge.bridge-nf-call-ip6tables=1

sysctl -p

重启服务:
systemctl restart openstack-nova-compute.service
启动服务:

systemctl enable neutron-linuxbridge-agent.service
systemctl start neutron-linuxbridge-agent.service
systemctl status neutron-linuxbridge-agent.service

此处服务起来一会后就自动关闭了

 

五、控制节点验证

设置admin环境变量

执行命令验证是否成功启动neutron-server

openstack extension list --network

执行命令列出插件,验证网络插件是否成功启动

openstack network agent list
