安装并配置控制节点

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';

运行环境变量

$ . admin-openrc

$ openstack user create --domain default --password-prompt neutron

配置网络选项

配置元数据代理

vi /etc/neutron/metadata_agent.ini
[DEFAULT]
...
nova_metadata_ip = controller
metadata_proxy_shared_secret = METADATA_SECRET

为计算节点配置网络

vi /etc/nova/nova.conf
[neutron]
...
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

service_metadata_proxy = True
metadata_proxy_shared_secret = METADATA_SECRET

完成安装

# 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
# 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 enable neutron-l3-agent.service
# systemctl start neutron-l3-agent.service

安装并配置计算节点

安装组件

# yum install openstack-neutron-linuxbridge ebtables ipset

配置通用组件

vi /etc/neutron/neutron.conf
[DEFAULT]
...
rpc_backend = rabbit

[oslo_messaging_rabbit]
...
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS

[DEFAULT]
...
auth_strategy = keystone

[keystone_authtoken]
...
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

[oslo_concurrency]
...
lock_path = /var/lib/neutron/tmp

为计算节点配置网络服务

vi /etc/nova/nova.conf
[neutron]
...
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

完成安装

1. 重启计算服务：

# systemctl restart openstack-nova-compute.service

2. 启动Linuxbridge代理并配置它开机自启动：

# systemctl enable neutron-linuxbridge-agent.service
# systemctl start neutron-linuxbridge-agent.service
