网络服务计算节点的安装及配置

1.安装服务

# yum install openstack-neutron-linuxbridge ebtables ipset -y

2.修改/etc/neutron/neutron.conf

[DEFAULT]
...
transport_url = rabbit://openstack:RABBIT_PASS@controller
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 = 123456
[oslo_concurrency]
...
lock_path = /var/lib/neutron/tmp

3.修改/etc/neutron/plugins/ml2/linuxbridge_agent.ini

[linux_bridge]
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME
[vxlan]
enable_vxlan = False
[securitygroup]
...
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

4.修改/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 = 123456

5.重启nova-compute服务

# systemctl restart openstack-nova-compute.service

6.启动服务

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

7.验证

# openstack network agent list
