##5 Neutron控制節點
###openstack-ocata 單節點安裝 部署 目錄彙總
一 建立資料庫
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';
--------------------------------------------------------------------------------
二 安裝neutron 使用者等
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 安裝自助網路模式 Self-service networks
yum install openstack-neutron openstack-neutron-ml2 \
openstack-neutron-linuxbridge ebtables -y
--------------------------------------------------------------------------------
四 配置自助網路模式檔案
#備份檔案
cp /etc/neutron/neutron.conf /etc/neutron/neutron.conf.bak
> /etc/neutron/neutron.conf
echo '
[database]

cp /etc/neutron/plugins/ml2/linuxbridge_agent.ini /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bak
> /etc/neutron/plugins/ml2/linuxbridge_agent.ini
###provider 根據自己網絡卡名稱修改 local_ip控制節點ip
echo '
[linux_bridge]
physical_interface_mappings = provider:ens33
[vxlan]
enable_vxlan = true
local_ip = 192.168.62.101

enable_isolated_metadata = true
'>>/etc/neutron/l3_agent.ini

region_name = RegionOne
project_name = service
username = neutron
password = neutron
service_metadata_proxy = true
metadata_proxy_shared_secret = METADATA_SECRET
--------------------------------------------------------------------------------
五 初始化資料
ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
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
--------------------------------------------------------------------------------
六 重啟nova服務，啟動neutron服務
systemctl restart openstack-nova-api.service
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
systemctl status neutron-server.service neutron-openvswitch-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
systemctl enable neutron-l3-agent.service
systemctl start neutron-l3-agent.service
systemctl status neutron-l3-agent.service
