openstack安裝（十）網絡服務的安裝--計算節點

安裝和配置計算節點

最終檢測："neutron 四個選項"

（1）安裝組件

yum install openstack-neutron-linuxbridge ebtables ipset -y

（2）修改配置文件

vim  /etc/neutron/neutron.conf

###############

'1:消息隊列'

[DEFAULT]
...
rpc_backend = rabbit

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

'2:認證'

[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

'3:鎖文件'

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

（3）計算節點配置二層網絡

####################（1）配置Linuxbridge代理-->在計算節點創建網橋

[linux_bridge]
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME(自己是eth0)

[vxlan]
enable_vxlan = False

[securitygroup]
...
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

（4）爲計算節點配置網絡服務

vim  /etc/nova/nova.conf

####### 修改配置文件

[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

（5）服務自啓動

    '重啓計算服務'

    systemctl restart openstack-nova-compute.service

    '啓動Linuxbridge代理並配置它開機自啓動'

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

（6）驗證

[root@controller ~]# neutron agent-list
