OpenStack Train版操作笔记（8） --- 安装neutron网络服务（计算节点）

1、安装配置组件

yum install openstack-neutron-linuxbridge ebtables ipset -y

修改配置文件 /etc/neutron/neutron.conf ：

[DEFAULT]
# ...
transport_url = rabbit://openstack:RABBIT_PASS@controller
auth_strategy = keystone


[keystone_authtoken]
# ...
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
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

修改配置文件 /etc/neutron/plugins/ml2/linuxbridge_agent.ini（自己手动添加）：

[linux_bridge]
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME

[vxlan]
enable_vxlan = false

[securitygroup]
# ...
enable_security_group = truefirewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

修改内核参数：

echo 'net.bridge.bridge-nf-call-iptables=1 net.bridge.bridge-nf-call-ip6tables=1' >> /etc/sysctl.conf
modprobe br_netfilter
sysctl -p

修改配置文件/etc/nova/nova.conf：

auth_url = http://controller:5000
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = NEUTRON_PASS

重启nova服务：

systemctl restart openstack-nova-compute.service

启动服务并设置开机自启动：

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

在controller节点执行以下命令进行验证：

neutron agent-list

确保四个服务状态都是启动状态（笑脸）
