openstack（五、Neutron)

http://www.cnblogs.com/CloudMan6/p/5922014.html
https://www.cnblogs.com/resn/p/5870264.html
ip netns list 命令列出所有的 namespace。
可以通过 ip netns exec <network namespace name> <command> 管理 namespace

1、创建neutron数据库

CREATE DATABASE neutron;

2、创建数据库用户并赋予权限

GRANT ALL PRIVILEGES ON neutron.* TO "neutron"@"localhost" IDENTIFIED BY "neutron";
GRANT ALL PRIVILEGES ON neutron.* TO "neutron"@"%" IDENTIFIED BY "neutron";

3、创建neutron用户及赋予admin权限

source /home/admin-openrc
openstack user create --domain default neutron --password neutron
openstack role add --project service --user neutron admin

4、创建network服务

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

5、创建endpoint

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

6、安装neutron相关软件

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

7、配置neutron配置文件/etc/neutron/neutron.conf

cp /etc/neutron/neutron.conf /etc/neutron/neutron.conf.bak
>/etc/neutron/neutron.conf
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 DEFAULT allow_overlapping_ips true
openstack-config --set /etc/neutron/neutron.conf DEFAULT auth_strategy keystone
openstack-config --set /etc/neutron/neutron.conf DEFAULT transport_url rabbit://openstack:openstack@controller
openstack-config --set /etc/neutron/neutron.conf DEFAULT notify_nova_on_port_status_changes True
openstack-config --set /etc/neutron/neutron.conf DEFAULT notify_nova_on_port_data_changes True
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken auth_uri http://controller:5000
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken auth_url http://controller:35357
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
openstack-config --set /etc/neutron/neutron.conf database connection mysql+pymysql://neutron:neutron@controller/neutron
openstack-config --set /etc/neutron/neutron.conf nova auth_url http://controller:35357
openstack-config --set /etc/neutron/neutron.conf nova auth_type password
openstack-config --set /etc/neutron/neutron.conf nova project_domain_name default
openstack-config --set /etc/neutron/neutron.conf nova user_domain_name default
openstack-config --set /etc/neutron/neutron.conf nova region_name RegionOne
openstack-config --set /etc/neutron/neutron.conf nova project_name service
openstack-config --set /etc/neutron/neutron.conf nova username nova
openstack-config --set /etc/neutron/neutron.conf nova password nova
openstack-config --set /etc/neutron/neutron.conf oslo_concurrency lock_path /var/lib/neutron/tmp

8、配置/etc/neutron/plugins/ml2/ml2_conf.ini

openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 type_drivers vlan,local,flat,vxlan,gre
openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 tenant_network_types vlan,local,flat,vxlan,gre
openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 mechanism_drivers linuxbridge
openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 extension_drivers port_security
openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini securitygroup enable_ipset True
openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini securitygroup firewall_driver neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2_type_flat flat_networks = provider #如果要配置flat网络就加上
openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2_type_vlan network_vlan_ranges default:3000:4000 #如果配置vlan就加上
openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2_type_vxlan  vni_ranges  1001:2000 #如果配置vxlan就加上

9、配置/etc/neutron/plugins/ml2/linuxbridge_agent.ini(如果控制节点做计算节点就配置）

openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini DEFAULT debug true
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini linux_bridge physical_interface_mappings default:em2
openstack-config --set /etc/neutron/plugins/ml2/linuxb2ridge_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

特别要注意这边的“em2”是系统中网络的接口名，如果要配置vlan的话，要求网管将连接的口设置成trunk模式。折腾好久才明白啊。

10、配置 /etc/neutron/l3_agent.ini

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

11、配置/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


openstack-config --set /etc/neutron/dhcp_agent.ini DEFAULT verbose True
openstack-config --set /etc/neutron/dhcp_agent.ini DEFAULT debug false

12、重新配置/etc/nova/nova.conf

配置这步的目的是让compute节点能使用上neutron网络

openstack-config --set /etc/nova/nova.conf neutron url http://controller:9696
openstack-config --set /etc/nova/nova.conf neutron auth_url http://controller:35357
openstack-config --set /etc/nova/nova.conf neutron auth_plugin password
openstack-config --set /etc/nova/nova.conf neutron project_domain_id default
openstack-config --set /etc/nova/nova.conf neutron user_domain_id 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
openstack-config --set /etc/nova/nova.conf neutron service_metadata_proxy True
openstack-config --set /etc/nova/nova.conf neutron metadata_proxy_shared_secret neutron-meta

13、将dhcp-option-force=26,1450写入/etc/neutron/dnsmasq-neutron.conf

echo "dhcp-option-force=26,1450" >/etc/neutron/dnsmasq-neutron.conf

14、配置/etc/neutron/metadata_agent.ini

openstack-config --set /etc/neutron/metadata_agent.ini DEFAULT nova_metadata_ip controller
openstack-config --set /etc/neutron/metadata_agent.ini DEFAULT metadata_proxy_shared_secret neutron-meta

15、创建硬链接

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

16、同步数据库

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

17、重启nova服务，因为刚才改了nova.conf

systemctl restart openstack-nova-api.service
systemctl status openstack-nova-api.service

18、重启neutron服务并设置开机启动

systemctl enable neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service neutron-l3-agent.service
systemctl restart neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service neutron-l3-agent.service
systemctl status neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service neutron-l3-agent.service

19、启动neutron-l3-agent.service并设置开机启动

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

20、执行验证

source /root/admin-openrc
neutron ext-list
neutron agent-list

节点安装
yum install openstack-neutron-linuxbridge ebtables ipset
1、配置网络

openstack-config --set /etc/neutron/neutron.conf DEFAULT auth_strategy keystone
openstack-config --set /etc/neutron/neutron.conf DEFAULT transport_url rabbit://openstack:openstack@controller
openstack-config --set /etc/neutron/neutron.conf DEFAULT advertise_mtu True
openstack-config --set /etc/neutron/neutron.conf DEFAULT dhcp_agents_per_network 2
openstack-config --set /etc/neutron/neutron.conf DEFAULT control_exchange neutron
openstack-config --set /etc/neutron/neutron.conf DEFAULT nova_url http://controller:8774/v2
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken auth_uri http://controller:5000
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken auth_url http://controller:35357
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
openstack-config --set /etc/neutron/neutron.conf oslo_concurrency lock_path /var/lib/neutron/tmp

3、配置/etc/neutron/plugins/ml2/linuxbridge_agent.ini

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 192.168.100.98
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
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini linux_bridge physical_interface_mappings default:em2

4、配置nova.conf

openstack-config --set /etc/nova/nova.conf neutron url http://controller:9696
openstack-config --set /etc/nova/nova.conf neutron auth_url http://controller:35357
openstack-config --set /etc/nova/nova.conf neutron auth_type password
