OpenStack的部署（六）------Neutron项目

配置接：OpenStack的部署（五）------NOVA项目

一、CT控制节点

CT VM:192.168.100.10 NAT:192.168.163.10

1、创建数据库neutron，并进行授权

mysql -u root -p
CREATE DATABASE neutron;
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'NEUTRON_DBPASS';
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'NEUTRON_DBPASS';
flush privileges;
exit

2、创建用户、服务并赋权

创建neutron用户，用于在keystone做认证
openstack user create --domain default --password NEUTRON_PASS neutron

将neutron用户添加到service项目中拥有管理员权限
openstack role add --project service --user neutron admin

创建network服务，服务类型为network
openstack service create --name neutron --description "OpenStack Networking" network

3、注册API

注册API到neutron服务，给neutron服务关联端口，即添加endpoint

openstack endpoint create --region RegionOne network public http://ct:9696
openstack endpoint create --region RegionOne network internal http://ct:9696
openstack endpoint create --region RegionOne network admin http://ct:9696

4、安装提供者网络(桥接)并修改相关配置文件

ebtables包是用来管理iptables规则的

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

修改主配置文件neutron.conf

cp -a /etc/neutron/neutron.conf{
    
    ,.bak}
grep -Ev '^$|#' /etc/neutron/neutron.conf.bak > /etc/neutron/neutron.conf

传参

修改 ML2 plugin 配置文件 ml2_conf.ini

cp -a /etc/neutron/plugins/ml2/ml2_conf.ini{
    
    ,.bak}
grep -Ev '^$|#' /etc/neutron/plugins/ml2/ml2_conf.ini.bak > /etc/neutron/plugins/ml2/ml2_conf.ini

传参（省略）

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

传参后查看

修改 linux bridge network provider 配置文件

cp -a /etc/neutron/plugins/ml2/linuxbridge_agent.ini{
    
    ,.bak}
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 192.168.100.10
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

修改内核参数

echo 'net.bridge.bridge-nf-call-iptables=1' >> /etc/sysctl.conf
echo 'net.bridge.bridge-nf-call-ip6tables=1' >> /etc/sysctl.conf
modprobe br_netfilter
sysctl -p

配置Linuxbridge接口驱动和外部网络网桥

cp -a /etc/neutron/l3_agent.ini{
    
    ,.bak}
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

修改dhcp_agent 配置文件

cp -a /etc/neutron/dhcp_agent.ini{
    
    ,.bak}
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

配置元数据代理、用于配置桥接与自服务网络的通用配置

cp -a /etc/neutron/metadata_agent.ini{
    
    ,.bak}
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

修改CT配置文件/etc/nova/nova.conf，用于neutron交互

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 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
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

创建ML2插件文件符号连接
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

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

初始化数据库

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

5、重启相关服务

重启计算节点nova-api服务

systemctl restart openstack-nova-api.service

开启neutron服务、设置开机自启动

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

netstat -anutp |grep 9696

因为配置了第三层L3网络服务、所以需要启动第三层服务

systemctl enable neutron-l3-agent.service
systemctl restart neutron-l3-agent.service

二、C1、C2计算节点操作

C1 VM:192.168.100.20 NAT:192.168.163.20
C2 VM:192.168.100.30 NAT:192.168.163.30

1、部署neutron服务

安装neutron即相关服务

yum -y install openstack-neutron-linuxbridge ebtables ipset conntrack-tools
#ipset：iptables的扩展，允许匹配规则的集合而不仅仅是一个IP

修改neutron.conf文件

cp -a /etc/neutron/neutron.conf{
    
    ,.bak}
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

2、配置Linux网桥代理

修改Linuxbridge网桥配置文件

cp -a /etc/neutron/plugins/ml2/linuxbridge_agent.ini{
    
    ,.bak}
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 192.168.100.20
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

修改内核

echo 'net.bridge.bridge-nf-call-iptables=1' >> /etc/sysctl.conf
echo 'net.bridge.bridge-nf-call-ip6tables=1' >> /etc/sysctl.conf
#modprobe：用于向内核中加载模块或者从内核中移除模块。modprobe -r 表示移除
modprobe br_netfilter
sysctl -p

修改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

三、 验证服务组件（ct节点）

openstack extension list --network
openstack network agent list

下一步:OpenStack的部署（七）------Dashboard组件

总结

三个节点都需要配置neutron网络，以下为部署思路：
配置neutron组件的用户、认证、endpoint
设置提供者provider网络（这里是桥接模式）
① 配置二层网络
② 配置网桥（插件）
③ 优化内核
④ 配置网桥接口与外部对接
⑤ 修改DHCP配置（修改配置文件、代理）
⑥ 配置网桥与内部组件的配置（修改配置文件、代理）
设置neutron与nova对接的配置
其中C1、C2节点配置相同
