A07. openstack架构实战-neutron计算节点安装
作者:互联网
计算节点neutron的安装
一:安装neutron相关软件包
ipset使用来批量控制iptables工具的
[root@compute01 ~]# yum install -y openstack-neutron-linuxbridge ebtables ipset
network的相关配置
Networking 通用组件的配置包括认证机制、消息队列和插件。
二:编辑``/etc/neutron/neutron.conf`` 文件并完成如下操作:
1:在``[database]`` 部分,注释所有``connection`` 项,因为计算节点不直接访问数据库。
在 “[DEFAULT]” 和 “[oslo_messaging_rabbit]”部分,配置 “RabbitMQ” 消息队列的连接:
[DEFAULT]
transport_url = rabbit://openstack:huayun@controller01
2:在 “[DEFAULT]” 和 “[keystone_authtoken]” 部分,配置认证服务访问
[DEFAULT]
auth_strategy = keystone
[keystone_authtoken]
auth_uri = http://controller01:5000
auth_url = http://controller01:35357
memcached_servers = controller01:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = huayun
3:在 [oslo_concurrency] 部分,配置锁路径:
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
三:配置网络(这里选择公共网络进行配置)
配置Linuxbridge代理
Linuxbridge代理为实例建立layer-2虚拟网络并且处理安全组规则。
编辑``/etc/neutron/plugins/ml2/linuxbridge_agent.ini``文件并且完成以下操作:
1:在``[linux_bridge]``部分,将公共虚拟网络和公共物理网络接口对应起来
[linux_bridge]
physical_interface_mappings = provider:ens192
2:在``[vxlan]``部分,禁止VXLAN覆盖网络:
[vxlan]
enable_vxlan = false
3:在 ``[securitygroup]``部分,启用安全组并配置 Linuxbridge iptables firewall driver:
[securitygroup]
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
4: 通过验证以下所有sysctl
值是否设置为确保Linux操作系统内核支持网桥过滤器(要启用网络桥接器支持,通常
br_netfilter
需要加载内核模块。)
[root@compute01 ~]# echo "net.bridge.bridge-nf-call-iptables = 1" >> /etc/sysctl.conf
[root@compute01 ~]# echo "net.bridge.bridge-nf-call-ip6tables = 1" >> /etc/sysctl.conf
sysctl -p
modinfo br_netfilter
modprobe br_netfilter
5:为计算节点配置网络服务¶
编辑``/etc/nova/nova.conf``文件并完成下面的操作
在``[neutron]`` 部分,配置访问参数:
[neutron]
url = http://controller01:9696
auth_url = http://controller01:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = huayun
完成安装¶
重启计算服务:
[root@compute01 ~]# systemctl restart openstack-nova-compute.service
启动Linuxbridge代理并配置它开机自启动:
[root@compute01 ~]# systemctl enable neutron-linuxbridge-agent.service && systemctl start neutron-linuxbridge-agent.service
校验
[root@controller01 ~]# neutron agent-list
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
