  • Post author:
  • Post category:其他




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:

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.



部署规划

主机名 IP地址 组件
controller 172.16.20.80 Keystone, Glance, Placement, Nova, Neutron, Horizon, Cinder
compute1 172.16.20.81 Nova, Neutron, Cinder
compute2 172.16.20.82 Nova, Neutron, Cinder



配置系统环境

  • 所有节点

参考官网: https://docs.openstack.org/install-guide/environment.html



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

  • controller节点

    cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
    vim /etc/chrony.conf
    # 配置如下
    server ntp1.aliyun.com iburst
    
    allow 172.16.20.0/24
    local stratum 10
    
    systemctl restart chronyd 
    
  • nova节点

    cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
    vim /etc/chrony.conf
    # 配置如下
    server controller
    
    systemctl restart chronyd
    
    # ntp同步验证:
    chronyc sources -v

如果启动过程中, 日志提示资源请求失败, 类似如下

ERROR nova.compute.manager nova.exception.ResourceProviderRetrievalFailed: Failed to get resource provider with UUID 7f58ca50-e98e-41b1-aa8b-9d227ff75aa2

解决方法:

在controller节点, 配置httpd
vim /etc/httpd/conf.d/00-placement-api.conf
在placement-api别名下
Alias /placement-api /usr/bin/placement-api
<Location /placement-api>
SetHandler wsgi-script
Options +ExecCGI
WSGIProcessGroup placement-api
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
</Location>
添加
<Directory /usr/bin>
<IfVersion >= 2.4>
   Require all granted
</IfVersion>
<IfVersion < 2.4>
   Order allow,deny
   Allow from all
</IfVersion>
</Directory>

systemctl restart httpd



添加计算节点到cell库

  • controller节点
# 载入环境变量
. admin-openrc

# 查看nova节点
openstack compute service list --service nova-compute

# 发现nova节点
su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

新注册节点需要执行节点发现, 否则节点无法上线, 也可以在controller节点配置自动发现

openstack catalog show object-store



启动服务

systemctl enable openstack-cinder-backup.service
systemctl start openstack-cinder-backup.service



Horizon

  • controller节点



安装Horizon

yum install openstack-dashboard -y



配置Horizon

vim /etc/openstack-dashboard/local_settings

OPENSTACK_HOST = "controller"

ALLOWED_HOSTS = ['*']

SESSION_ENGINE = 'django.contrib.sessions.backends.cache'

CACHES = {
    'default': {
         'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
         'LOCATION': 'controller:11211',
    }
}

OPENSTACK_KEYSTONE_URL = "http://%s/identity/v3" % OPENSTACK_HOST

OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True

OPENSTACK_API_VERSIONS = {
    "identity": 3,
    "image": 2,
    "volume": 3,
}

OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default"

OPENSTACK_KEYSTONE_DEFAULT_ROLE = "admin"

OPENSTACK_NEUTRON_NETWORK = {
    'enable_router': False,
    'enable_quotas': False,
    'enable_distributed_router': False,
    'enable_ha_router': False,
    'enable_lb': False,
    'enable_firewall': False,
    'enable_vpn': False,
    'enable_fip_topology_check': False,
}

TIME_ZONE = "Asia/Shanghai"

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

  1. 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
  1. 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
