时间：2022-12-07 22:32:57

在计算节点安装neutron网络服务（computel01计算节点192.168.0.20）
安装组件

yum install openstack-neutron-linuxbridge ebtables ipset -y

yum install conntrack-tools -y

修改neutron主配置文件/etc/neutron/neutron.conf

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@controller

openstack-config --set /etc/neutron/neutron.conf DEFAULT auth_strategy keystone

openstack-config --set /etc/neutron/neutron.conf keystone_authtoken www_authenticate_uri http://controller:5000

openstack-config --set /etc/neutron/neutron.conf keystone_authtoken auth_url http://controller:5000

openstack-config --set /etc/neutron/neutron.conf keystone_authtoken memcached_servers controller: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

配置Linux网桥代理

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 192.168.0.20

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linux系统内核网桥参数为1

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

配置计算节点上Nova服务使用网络服务

#修改nova配置文件/etc/nova/nova.conf，添加neutron模块配置

openstack-config --set /etc/nova/nova.conf neutron auth_url http://controller: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

重新启动计算节点上的Nova服务

systemctl restart openstack-nova-compute.service

启动neutron网桥代理服务 设置开机自启动

systemctl enable neutron-linuxbridge-agent.service

systemctl restart neutron-linuxbridge-agent.service

回到控制节点验证Neutron网络服务-（controller控制节点192.168.0.10）

#列出已加载的扩展，以验证该neutron-server过程是否成功启动

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

#列出代理商以验证成功

[root@controller ~]# openstack network agent list
