Openstack 网络服务 Neutron计算节点部署 （十一）

一） Neutron计算节点部署

1、安装软件包

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

2、配置文件neutron.conf

因为neutron控制节点跟计算节点配置几乎一样，直接复制控制节点的文件到计算节点，将不同的部分进行修改。
[root@controller ~]# scp -p /etc/neutron/neutron.conf root@compute:/etc/neutron/
注意：需保持权限相同

编辑配置文件neutron.conf

# vim /etc/neutron/neutron.conf
[database]
#connection =                        # 删除mysql连接路径
[nova]                               # 删除nova标签下keystone配置,所有配置
#notify_nova_on_port_status_changes = true # 注释
#notify_nova_on_port_data_changes = true # 注释
#core_plugin = ml2 # 注释
#service_plugins = # 注释

[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 = redhat

编辑配置文件linuxbridge_agent.ini

[root@compute ~]# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini

[linux_bridge] #将公共虚拟网络和公共物理网络接口对应起来
physical_interface_mappings = provider:ens33

[vxlan] #禁止VXLAN覆盖网络
enable_vxlan = False

[securitygroup] #启用安全组并配置防火墙驱动
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

　　

重启计算节点nova-compute

# systemctl restart openstack-nova-compute.service

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

进入控制节点（controller)检查

[root@controller ~]# source admin-openrc
[root@controller ~]# neutron agent-list
