中小企业openstack私有云布署实践【13.2 网络Neutron-compute节点配置(办公网环境)】

所有compute节点
下载安装组件
 
# yum install openstack-neutron openstack-neutron-linuxbridge ebtables ipset -y
修改新增内核参数:
 
vi /etc/sysctl.conf
 
net.ipv4.conf.default.rp_filter=0
net.ipv4.conf.all.rp_filter=0
net.bridge.bridge-nf-call-iptables=1
net.bridge.bridge-nf-call-ip6tables=1
 
sysctl -p
 
提示:sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-iptables: 没有那个文件或目录
sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-ip6tables: 没有那个文件或目录
解决方法如下:
modprobe bridge
lsmod|grep bridge
 
sysctl -p
 
1公有网络配置+私有网络配置-----------------这里我以compute1节点为例,其它节点的配置是相同的,只是IP 和 网卡对应的名称不同而已
 
配置neutron服务
vi  /etc/neutron/neutron.conf
 
[DEFAULT]
rpc_backend = rabbit
auth_strategy = keystone
verbose = True
 
[oslo_messaging_rabbit]
rabbit_host=controller
rabbit_userid = openstack
rabbit_password = openstack
rabbit_retry_interval=1
rabbit_retry_backoff=2
rabbit_max_retries=0
rabbit_durable_queues=true
rabbit_ha_queues=true
 
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = neutron
password = neutron
 
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
 
配置Linux bridge服务
vi /etc/neutron/plugins/ml2/linuxbridge_agent.ini
 
[linux_bridge]
physical_interface_mappings = public:bond0
 
[vxlan]
enable_vxlan = True
local_ip = 10.40.42.11
l2_population = False
 
[agent]
prevent_arp_spoofing = True
 
[securitygroup]
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
enable_ipset = True
 
 
 
添加neutron服务到nova中-----在11节中我就有提到的那个紫色的提前配置,这里再提一次
vi /etc/nova/nova.conf
 
[neutron]
url = http://controller:9696
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron
 
 
 
重启nova api服务
# systemctl restart openstack-nova-compute.service
开机自启,开启服务
# systemctl enable neutron-linuxbridge-agent.service
# systemctl restart neutron-linuxbridge-agent.service
 
验证:
在controller上
 
source admin-openrc.sh
