OpenStack——neutron组件部署

一、ct节点部署

1、创建neutron数据库，并授权

MariaDB [nova]> CREATE DATABASE neutron;

MariaDB [nova]> GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron’@‘localhost’ IDENTIFIED BY ‘NEUTRON_DBPASS’;

MariaDB [nova]> GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron’@’%’ IDENTIFIED BY ‘NEUTRON_DBPASS’;

MariaDB [nova]> FLUSH PRIVILEGES;

2、创建neutron用户，用于在keystone做认证

[root@ct ~]# openstack user create --domain default --password NEUTRON_PASS neutron

3、将neutron用户添加到service项目

#使其拥有管理员权限

[root@ct ~]# openstack role add --project service --user neutron admin

4、创建network服务，服务类型为network

[root@ct ~]# openstack service create --name neutron --description “OpenStack Networking” network

5、注册API到neutron服务

#给neutron服务关联端口，即添加endpoint

[root@ct ~]# openstack endpoint create --region RegionOne network public http://ct:9696

[root@ct ~]# openstack endpoint create --region RegionOne network internal http://ct:9696

[root@ct ~]# openstack endpoint create --region RegionOne network admin http://ct:9696

6、安装提供者网络

#ebtables包是用来管理iptables规则的

[root@ct ~]# yum -y install openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge ebtables conntrack-tools

7、修改主配置文件

[root@ct ~]# cp -a /etc/neutron/neutron.conf{,.bak}

[root@ct ~]# grep -Ev ‘^$|#’ /etc/neutron/neutron.conf.bak > /etc/neutron/neutron.conf

openstack-config --set /etc/neutron/neutron.conf database connection mysql+pymysql://neutron:NEUTRON_DBPASS@ct/neutron
openstack-config --set /etc/neutron/neutron.conf DEFAULT core_plugin ml2
openstack-config --set /etc/neutron/neutron.conf DEFAULT service_plugins router

openstack-config --set /etc/neutron/neutron.conf nova password NOVA_PASS

8、修改ML2的配置文件

[root@ct ~]# cp -a /etc/neutron/plugins/ml2/ml2_conf.ini{,.bak}

[root@ct ml2]# grep -Ev ‘^$|#’ /etc/neutron/plugins/ml2/ml2_conf.ini.bak > /etc/neutron/plugins/ml2/ml2_conf.ini

openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 type_drivers flat,vlan,vxlan
openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 tenant_network_types vxlan

openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini securitygroup enable_ipset true

9、修改linux bridge network provider 配置文件 linuxbridge_agent.ini

[root@ct ~]# cp -a /etc/neutron/plugins/ml2/linuxbridge_agent.ini{,.bak}

[root@ct ~]# grep -Ev ‘^$|#’ /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bak > /etc/neutron/plugins/ml2/linuxbridge_agent.ini

openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini linux_bridge physical_interface_mappings provider:eth0
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini vxlan enable_vxlan true
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini vxlan local_ip 192.168.200.11
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini vxlan l2_population true
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini securitygroup enable_security_group true
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini securitygroup firewall_driver neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

10、修改内核参数

[root@ct ~]# echo ‘net.bridge.bridge-nf-call-iptables=1’ >> /etc/sysctl.conf
[root@ct ~]# echo ‘net.bridge.bridge-nf-call-ip6tables=1’ >> /etc/sysctl.conf
[root@ct ~]# modprobe br_netfilter
[root@ct ~]# sysctl -p

11、配置linuxbridge接口驱动和外部网络网桥

[root@ct ~]# cp -a /etc/neutron/l3_agent.ini{,.bak}

[root@ct ~]# grep -Ev ‘^$|#’ /etc/neutron/l3_agent.ini.bak > /etc/neutron/l3_agent.ini

openstack-config --set /etc/neutron/l3_agent.ini DEFAULT interface_driver linuxbridge

12、修改dhcp_agent配置文件

[root@ct ~]# cp -a /etc/neutron/dhcp_agent.ini{,.bak}

[root@ct ~]# grep -Ev ‘^$|#’ /etc/neutron/dhcp_agent.ini.bak > /etc/neutron/dhcp_agent.ini

openstack-config --set /etc/neutron/dhcp_agent.ini DEFAULT interface_driver linuxbridge
openstack-config --set /etc/neutron/dhcp_agent.ini DEFAULT dhcp_driver neutron.agent.linux.dhcp.Dnsmasq
openstack-config --set /etc/neutron/dhcp_agent.ini DEFAULT enable_isolated_metadata true

13、配置元数据代理、用于配置桥接与自服务网络的通用配置

[root@ct ~]# cp -a /etc/neutron/metadata_agent.ini{,.bak}

[root@ct ~]# grep -Ev ‘^$|#’ /etc/neutron/metadata_agent.ini.bak > /etc/neutron/metadata_agent.ini

openstack-config --set /etc/neutron/metadata_agent.ini DEFAULT nova_metadata_host ct
openstack-config --set /etc/neutron/metadata_agent.ini DEFAULT metadata_proxy_shared_secret METADATA_SECRET

14、修改nova配置文件

openstack-config --set /etc/nova/nova.conf neutron url http://ct:9696
openstack-config --set /etc/nova/nova.conf neutron auth_url http://ct:5000
openstack-config --set /etc/nova/nova.conf neutron auth_type password

openstack-config --set /etc/nova/nova.conf neutron service_metadata_proxy true
openstack-config --set /etc/nova/nova.conf neutron metadata_proxy_shared_secret METADATA_SECRET

15、创建ML2插件文件符号链接

#网络服务初始化脚本需要/etc/neutron/plugin.ini指向ML2插件配置文件的符号链接

[root@ct ~]# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

16、初始化数据库

[root@ct ~]# 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

17、重启nova-api服务

[root@ct ~]# systemctl restart openstack-nova-api.service

18、开启neutron服务

[root@ct ~]# systemctl enable neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service

[root@ct ~]# systemctl start neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service

[root@ct ~]# netstat -anutp |grep 9696

19、启动第三层网络网络服务

#因为配置了第三层L3网络服务、所以需要启动第三层服务

[root@ct ~]# systemctl restart neutron-l3-agent.service
[root@ct ~]# systemctl enable neutron-l3-agent.service

二、节点1配置

1、pset：iptables的扩展，允许匹配规则的集合而不仅仅是一个IP

[root@c1 ~]# yum -y install openstack-neutron-linuxbridge ebtables ipset conntrack-tools

2、修改neutron文件

[root@c1 ~]# cp -a /etc/neutron/neutron.conf{,.bak}

[root@c1 ~]# grep -Ev ‘^$|#’ /etc/neutron/neutron.conf.bak > /etc/neutron/neutron.conf

openstack-config --set /etc/neutron/neutron.conf DEFAULT transport_url rabbit://openstack:RABBIT_PASS@ct
openstack-config --set /etc/neutron/neutron.conf DEFAULT auth_strategy keystone
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken www_authenticate_uri http://ct:5000
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken auth_url http://ct:5000
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken memcached_servers ct:11211
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken auth_type password
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken project_domain_name default
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken user_domain_name default
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken project_name service
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken username neutron
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken password NEUTRON_PASS
openstack-config --set /etc/neutron/neutron.conf oslo_concurrency lock_path /var/lib/neutron/tmp

3、配置linux网桥代理

[root@c1 ~]# cp -a /etc/neutron/plugins/ml2/linuxbridge_agent.ini{,.bak}

[root@c1 ~]# grep -Ev ‘^$|#’ /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bak > /etc/neutron/plugins/ml2/linuxbridge_agent.ini

openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini linux_bridge physical_interface_mappings provider:eth0
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini vxlan enable_vxlan true
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini vxlan local_ip 192.168.100.12
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini vxlan l2_population true
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini securitygroup enable_security_group true
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini securitygroup firewall_driver neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

4、修改内核

[root@c1 ~]# echo ‘net.bridge.bridge-nf-call-iptables=1’ >> /etc/sysctl.conf
[root@c1 ~]# echo ‘net.bridge.bridge-nf-call-ip6tables=1’ >> /etc/sysctl.conf
[root@c1 ~]# modprobe br_netfilter
[root@c1 ~]# sysctl -p

5、配置nova.conf配置文件

openstack-config --set /etc/nova/nova.conf neutron auth_url http://ct:5000
openstack-config --set /etc/nova/nova.conf neutron auth_type password
openstack-config --set /etc/nova/nova.conf neutron project_domain_name default
openstack-config --set /etc/nova/nova.conf neutron user_domain_name default
openstack-config --set /etc/nova/nova.conf neutron region_name RegionOne
openstack-config --set /etc/nova/nova.conf neutron project_name service
openstack-config --set /etc/nova/nova.conf neutron username neutron
openstack-config --set /etc/nova/nova.conf neutron password NEUTRON_PASS

6、ct节点进行验证

[root@ct ~]# openstack extension list --network

[root@ct ~]# openstack network agent list
