openstack M版安装 network(neutron)服务篇
安装配置network(neutron) 服务Mitaka版本网络有两个选择，Provider network 和Self-service network，这里我们选择第二种。
controller 节点
一、创建数据库
# 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'; NEUTRON_DBPASS改为自己想要设置的密码
二、创建服务实体和api接口
# source /root/admin-openrc.sh
# openstack user create --domain default --password-prompt neutron
# openstack role add --project service --user neutron admin
# openstack service create --name neutron --description "OpenStack Networking" network
# 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
三、安装nuetron服务
# yum install openstack-neutron openstack-neutron-ml2openstack-neutron-linuxbridge ebtables 编辑neutron服务配置文件
# mv /etc/neutron/neutron.conf /etc/neutron/neutron.conf_bak
# vim /etc/neutron/neutron.conf
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = True
rpc_backend = rabbit
auth_strategy = keystone
notify_nova_on_port_status_changes = True
notify_nova_on_port_data_changes = True
connection = mysql+pymysql://neutron:NEUTRON_DBPASS@controller/neutron#改为自己数据库密码
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS #改为rabbitmq的密码
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = NEUTRON_PASS #改为自己neutron服务的密码
auth_url = http://controller:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = nova
password = NOVA_PASS#改为自己nova服务的密码
lock_path = /var/lib/neutron/tmp 编辑ML2插件的配置
#mv /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugins/ml2/ml2_conf.ini_bak
#vim /etc/neutron/plugins/ml2/ml2_conf.ini
type_drivers = flat,vlan,vxlan
tenant_network_types = vxlan
mechanism_drivers = linuxbridge,l2population
extension_drivers = port_security
flat_networks = provider
vni_ranges = 1:1000
enable_ipset = True 编辑linuxbridge agent 配置文件
#mv /etc/neutron/plugins/ml2/linuxbridge_agent.ini /etc/neutron/plugins/ml2/linuxbridge_agent.ini_bak
#vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME #这里设置为provider网络的网卡名称，我这里eth1
enable_vxlan = True
local_ip = OVERLAY_INTERFACE_IP_ADDRESS#这个ip地址我们使用的是管理网段的ip (10.0.0.11)
l2_population = True
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
编辑L3 agent 配置文件
#mv /etc/neutron/l3_agent.ini /etc/neutron/l3_agent.ini_bak
#vim /etc/neutron/l3_agent.ini
interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
external_network_bridge = #留空 编辑dhcp agent配置
#mv /etc/neutron/dhcp_agent.ini /etc/neutron/dhcp_agent.ini_bak
#vim /etc/neutron/dhcp_agent.ini
interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_metadata = True 配置metadata agent
#mv /etc/neutron/metadata_agent.ini /etc/neutron/metadata_agent.ini_bak
#vim /etc/neutron/metadata_agent.ini
nova_metadata_ip = controller
metadata_proxy_shared_secret = METADATA_SECRET #修改为自己的METADATA_SECRET,也可以不修改，要和nova服务配置一样 配置nova服务使用network
#vim /etc/nova/nova.conf #增加以下内容
url = http://controller:9696
auth_url = http://controller:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = NEUTRON_PASS #改为自己neutron服务密码
service_metadata_proxy = True
metadata_proxy_shared_secret = METADATA_SECRET #和上面的METADATA对应 给ML2插件做个软连接
# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini 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 重启nova-api
# systemctl restart openstack-nova-api.service
启动neutron相关服务，并设置开机启动
# systemctl enable neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
# systemctl start neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service 启动L3 agent
# systemctl enable neutron-l3-agent.service
# systemctl start neutron-l3-agent.service
compute 节点配置
一、安装neutron服务
# yum install openstack-neutron-linuxbridge ebtables ipset 编辑neutron服务配置
#mv /etc/neutron/neutron.conf /etc/neutron/neutron.conf_bak
#vim /etc/neutron/neutron.conf
rpc_backend = rabbit
auth_strategy = keystone
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS #改为rabbit密码
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = NEUTRON_PASS #改为自己neutron服务密码
lock_path = /var/lib/neutron/tmp 编辑linuxbridge agent 配置
#mv /etc/neutron/plugins/ml2/linuxbridge_agent.ini /etc/neutron/plugins/ml2/linuxbridge_agent.ini_bak
#vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME#改为provider网络的网卡，这里是eth1
enable_vxlan = True
local_ip = OVERLAY_INTERFACE_IP_ADDRESS #改为本机managent网络的ip地址 10.0.0.31
l2_population = True
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
配置nova服务使用network
#vim/etc/nova/nova.conf#增加以下内容
url = http://controller:9696
auth_url = http://controller:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = NEUTRON_PASS #改为自己的neutron服务密码
重启nova服务
# systemctl restart openstack-nova-compute.service 启动neutron服务，并加入开机启动
# systemctl enable neutron-linuxbridge-agent.service
# systemctl start neutron-linuxbridge-agent.service
验证
在controller节点执行
#source /root/admin-openrc.sh
