前置条件
系统和版本
CentOS版本和OpenStack版本对应关系, 参考阿里云镜像站
CentOS 7
- https://mirrors.aliyun.com/centos/7/cloud/x86_64/
- 支持到Train版本
CentOS 8
- https://mirrors.aliyun.com/centos/8/cloud/x86_64/
- 支持版本, 从Train版本到Victoria版本
系统环境要求
1. 卸载firewall服务
2. 卸载NetworkManager服务
3. 关闭selinux
4. 主机名互通- host文件
5. 使用ntp服务器
6. /etc/resolv.conf取消search开头的行
7. CentOS 8操作系统最低配置要求:
- Controller Node:
- 内存: 8G以上
- 磁盘: 40G以上
- Compute Note:
- 内存: 4G以上
- 磁盘: 40G * 2 (compute node需要充当 storage node, 另外使用一块存储盘)
最小安装所需组件
来源官网: https://docs.openstack.org/install-guide/openstack-services.html
At a minimum, you need to install the following services. Install the services in the order specified below:
-
Identity service –
keystone installation for Wallaby
-
Image service –
glance installation for Wallaby
-
Placement service –
placement installation for Wallaby
-
Compute service –
nova installation for Wallaby
-
Networking service –
neutron installation for Wallaby
-
Dashboard –
horizon installation for Wallaby
-
Block Storage service –
cinder installation for Wallaby
This example architecture differs from a minimal production architecture as follows:
- Networking agents reside on the controller node instead of one or more dedicated network nodes.
- Overlay (tunnel) traffic for self-service networks traverses the management network instead of a dedicated network.

配置yum源
# 更换阿里云Base源
curl -o /etc/yum.repos.d/CentOS-Linux-BaseOS.repo https://mirrors.aliyun.com/repo/Centos-8.repo
sed -i '/failovermethod/d' /etc/yum.repos.d/CentOS-Linux-BaseOS.repo
# 安装openstack官方源
yum install centos-release-openstack-victoria -y
# 开启powertools
yum config-manager --set-enabled powertools
yum clean all
yum makecache
安装常用工具
yum install wget rsync vim net-tools network-scripts chrony -y
yum install python3-openstackclient openstack-selinux -y
关闭防火墙
openstack会接管系统防火墙配置, 所以要禁用firewalld服务
systemctl stop firewalld
systemctl disable firewalld
关闭NetworkManager
由于openstack网络交由neutron组件管理, 会不兼容主机自带的NetworkManager, 所以要将其卸载
systemctl stop NetworkManager
systemctl disable NetworkManager
# 配置network-scripts接管网络
systemctl start network
systemctl enable network
# 由于安装了network-scripts, 关闭NetworkManager后可使用network.service接管网络, 否则重启后网卡无法启动
关闭Selinux
# 临时关闭
setenforce 0
# 永久关闭
vim /etc/selinux/config
修改
SELINUX=disabled
设置主机名
# 根据规划配置, controller节点示例:
hostnamectl set-hostname controller
配置hosts
vim /etc/hosts
加入
172.16.20.80 controller
172.16.20.81 compute1
172.16.20.82 compute2
# 将hosts同步其余节点
配置ntp服务
controller节点配置chronyd服务, nova1和nova2节点为客户端
-

Mysql数据库配置
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'MysqlC1nder';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'MysqlC1nder';
注册Cinder到Keystone
载入环境变量
. admin-openrc
创建cinder用户
openstack user create --domain default --password-prompt cinder
# 口令: C1nderPwd
将cinder用户绑定到service项目的admin角色
openstack role add --project service --user cinder admin
创建cinderv2和cinderv3服务
openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2
openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3
为cinder服务创建API接口

创建LVM卷组
- 这里已加入硬盘, 驱动器sdb
pvcreate /dev/sdb
vgcreate cinder-volumes /dev/sdb
vim /etc/lvm/lvm.conf
配置如下
devices {
filter = [ "a/sdb/", "r/.*/"]
如果还有sdc, sdd, 直接逗号分割, 结尾为
r/.*/

启动cinder
systemctl enable openstack-cinder-volume.service target.service
systemctl start openstack-cinder-volume.service target.service
备份节点
安装cinder
yum install openstack-cinder
配置cinder
[DEFAULT]
backup_driver = cinder.backup.drivers.swift.SwiftBackupDriver
backup_swift_url = SWIFT_URL
SWIFT_URL为对象存储服务的 URL, 可通过controller节点使用命令查看 openstack catalog show object-store
启动服务
systemctl enable openstack-cinder-backup.service
systemctl start openstack-cinder-backup.service

处理bug, 在httpd配置中加入 WSGIApplicationGroup %{GLOBAL}
vim /etc/httpd/conf.d/openstack-dashboard.conf
加入
WSGIApplicationGroup %{GLOBAL}
重启服务
systemctl restart httpd.service memcached.service
验证Horizon
http://controller/dashboard
排错
- 默认httpd的dashboard配置文件无法访问Horizon主页, 需要重新生成httpd的dashboard配置文件
# 建立策略的软链接
ln -s /etc/openstack-dashboard /usr/share/openstack-dashboard/openstack_dashboard/conf
# 重新生成apache配置文件
cd /usr/share/openstack-dashboard
python3 manage.py make_web_conf --apache > /etc/httpd/conf.d/openstack-dashboard.conf
systemctl restart httpd.service memcached.service
- 解决登录horizon后无法进入身份管理
vim /etc/openstack-dashboard/local_settings
最下方加入
WEBROOT = '/dashboard/'
vim /etc/httpd/conf.d/openstack-dashboard.conf
修改如下
WSGIScriptAlias /dashboard /usr/share/openstack-dashboard/openstack_dashboard/wsgi.py
Alias /dashboard/static /usr/share/openstack-dashboard/static
常用操作
CentOS镜像下载
https://cloud.centos.org/centos/
修改密码功能
- compute节点
vim /etc/nova/nova.conf
inject_password=true
inject_partition = -1
- horizon节点
vim /etc/openstack-dashboard/local_settings
OPENSTACK_HYPERVISOR_FEATURES = {
'can_set_password': True,
}
- 操作方法
创建实例--> 配置--> 添加如下脚本(Aa123456为默认密码), 并勾选配置驱动
#!/bin/bash
echo Aa123456 | passwd --stdin root
sed -i 's#^PasswordAuthentication.*$#PasswordAuthentication\ yes#g' /etc/ssh/sshd_config
systemctl restart sshd
网络配置流程
示例:
- 测试环境, 暂时用管理段IP代模拟外网IP
网络拓扑:
WAN网络 -- 172.16.20.0/24
租户LAN网络 -- 10.10.0.0/16
配置流程:
admin管理员
- 创建WAN网络
登录openstack--> 管理员--> 网络--> 创建网络:
名称: 自定义, 如wan
项目: 关联项目, 这里选admin
类型: flat(直连)
物理网络: provider(对应neutron中配的flat_networks)
其余复选框选项: 启用管理员状态、共享的、外部网络
- 配置租户WAN网IP
登录openstack--> 项目--> 网络--> 在wan网actions中选择创建子网:
子网名称: 自定义, 如wan_subnet
网络地址: 172.16.20.0.24
IP版本: IPV4
网关: 172.16.20.1
下一步, 子网详情
DHCP地址池: 勾选激活
分配地址池: 172.16.20.150,172.16.20.157 //这里模拟外网IP
DNS: 自定义
创建网络
租户管理者
- 创建租户网络
- 创建LAN网络
登录openstack--> 项目--> 网络--> 创建网络:
名称: 自定义, 如project_lan
复选框选项: 启用管理员状态、创建子网
下一步, 创建子网
名称: 自定义, 如project_lan_subnet
网络地址: 10.10.0.0/16
IP版本: IPV4
网关IP: 10.10.0.1
下一步, DHCP配置
激活DHCP: 勾选
分配地址池: 10.10.0.2,10.10.0.254
DNS服务器: 自定义
创建网络
- 创建租户LAN网路由
登录openstack--> 项目--> 网络-->网络拓扑-->
- 新建路由
路由名称: project_route
启用管理员状态: 勾选
外部网络: 选择之前定义的WAN网络
新建路由
- 配置路由
鼠标放置新建好的路由接口:
选择添加接口
子网: 选择自定义子网网络
IP地址: 填写自定义子网网络的网关
提交
# 到此, 最简单的内外网模式配置完毕
