一、实验
1.环境
(1) 主机
表1 主机
|------------|-------|-----------------|-----|
| 主机 | 架构 | IP | 备注 |
| controller | 控制节点 | 192.168.204.210 | 已部署 |
| compute01 | 计算节点1 | 192.168.204.211 | 已部署 |
| compute02 | 计算节点2 | 192.168.204.212 | |
(2)官网
OpenStack Docs: OpenStack Installation Guide for Red Hat Enterprise Linux and CentOS
(3)网络
①计算节点2 ping 控制节点

②计算节点2 ping 计算节点1

(4) 时间同步
① 计算节点2
bash
[root@compute02 ~]# yum install -y chrony
bash
[root@compute02 ~]# vim /etc/chrony.conf
[root@compute02 ~]# systemctl restart chronyd.service && systemctl enable chronyd.service
③测试
bash
[root@controller ~]# date
[root@compute01 ~]# date
[root@compute02 ~]# date



(5) 控制节点查看(目前已部署controller与compute01)
bash
# neutron agent-list

2. 计算服务安装(计算节点2)
(1)安装软件包
bash
# yum install python-openstackclient.noarch openstack-selinux.noarch -y
# yum install openstack-nova-compute libvirt -y
# yum install openstack-utils.noarch -y

(2)编辑/etc/nova/nova.conf
①在[DEFAULT]和 [oslo_messaging_rabbit]部分,配置RabbitMQ消息队列的连接
bash
[DEFAULT]
...
rpc_backend = rabbit
[oslo_messaging_rabbit]
...
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS
② 在 [DEFAULT]和 [keystone_authtoken] 部分,配置认证服务访问
bash
[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 = nova
password = NOVA_PASS
③ 在 [DEFAULT] 部分,配置 my_ip 选项
bash
[DEFAULT]
...
my_ip = 192.168.204.212
④ 在 [DEFAULT] 部分,使能 Networking 服务
bash
[DEFAULT]
...
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
⑤ 在[vnc]部分,启用并配置远程控制台访问
bash
[vnc]
...
enabled = True
vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = $my_ip
novncproxy_base_url = http://controller:6080/vnc_auto.html
⑥在 [glance] 区域,配置镜像服务 API 的位置
bash
[glance]
...
api_servers = http://controller:9292
⑦ 在 [oslo_concurrency] 部分,配置锁路径
bash
[oslo_concurrency]
...
lock_path = /var/lib/nova/tmp
⑧ 备份修改
(3)完成安装
① 确定计算节点是否支持虚拟机的硬件加速
bash
$ egrep -c '(vmx|svm)' /proc/cpuinfo

(4)验证操作
3. 网络服务安装(计算节点2)
(1)安装组件
bash
# yum install openstack-neutron-linuxbridge ebtables ipset
(2)配置通用组件,编辑/etc/neutron/neutron.conf文件
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;
②在 [DEFAULT]和 [oslo_messaging_rabbit]部分,配置 RabbitMQ消息队列的连接
bash
[DEFAULT]
...
rpc_backend = rabbit
[oslo_messaging_rabbit]
...
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS
③ 在 [DEFAULT]和 [keystone_authtoken]部分,配置认证服务访问(将 NEUTRON_PASS 替换为在认证服务中为 neutron 用户选择的密码)
bash
[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
④ 在 [oslo_concurrency] 部分,配置锁路径
bash
[oslo_concurrency]
...
lock_path = /var/lib/neutron/tmp
⑤ 备份修改

(3) 配置Linuxbridge代理,编辑/etc/neutron/plugins/ml2/linuxbridge_agent.ini
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
bash
[linux_bridge]
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME
② 在[vxlan]部分,禁止VXLAN覆盖网络
bash
[vxlan]
enable_vxlan = False
③ 在 [securitygroup]部分,启用安全组并配置 Linuxbridge iptables firewall driver
bash
[securitygroup]
...
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
④ 备份修改

(4)配置网络选项,编辑/etc/nova/nova.conf文件
①在[neutron]部分,配置访问参数
bash
[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) 查看服务列表
bash
# openstack compute service list


(6)完成安装
①重启计算服务
bash
# systemctl restart openstack-nova-compute.service
②启动Linuxbridge代理并配置它开机自启动
bash
# systemctl enable neutron-linuxbridge-agent.service
# systemctl start neutron-linuxbridge-agent.service

(7)控制节点查看(已新增compute02)
bash
# neutron agent-list
