CentOS Stream 8 通过 Packstack 安装开源 OpenStack（Victoria版本）

第一章：环境准备

1.1 系统要求
主机名IP网关/DNSCPU/内存磁盘角色备注
controller01192.168.100.101192.168.100.24C/8G100G控制/网络/计算节点必须开启虚拟化引擎
compute02192.168.100.102192.168.100.24C/8G100G计算节点必须开启虚拟化引擎
1.2 网络配置

控制节点网络配置

[root@controller01 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens160
TYPE=Ethernet
BOOTPROTO=none
NAME=ens160
DEVICE=ens160
ONBOOT=yes
IPADDR=192.168.100.101
NETMASK=255.255.255.0
GATEWAY=192.168.100.2
DNS1=192.168.100.2

计算节点网络配置

[root@compute02 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens160
TYPE=Ethernet
BOOTPROTO=none
NAME=ens160
DEVICE=ens160
ONBOOT=yes
IPADDR=192.168.100.102
NETMASK=255.255.255.0
GATEWAY=192.168.100.2
DNS1=192.168.100.2
1.3 安全配置

控制节点安全配置

# 关闭防火墙
[root@controller01 ~]# systemctl stop firewalld
[root@controller01 ~]# systemctl disable firewalld# 关闭 Selinux
[root@controller01 ~]# setenforce 0
[root@controller01 ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config# 关闭 NetworkManager
[root@controller01 ~]# systemctl stop NetworkManager
[root@controller01 ~]# systemctl disable NetworkManager

计算节点安全配置

# 关闭防火墙
[root@compute02 ~]# systemctl stop firewalld
[root@compute02 ~]# systemctl disable firewalld# 关闭 Selinux
[root@compute02 ~]# setenforce 0
[root@compute02 ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config# 关闭 NetworkManager
[root@compute02 ~]# systemctl stop NetworkManager
[root@compute02 ~]# systemctl disable NetworkManager

注意：CentOS 8 版本默认使用 NetworkManager 管理网络，NetworkManager 会和 OpenStack 网络组件产生冲突，从而导致告警或错误：

  • Warning: NetworkManager is active on 192.168.100.101, 192.168.100.102. OpenStack networking currently does not work on systems that have the Network Manager service enabled.
  • 翻译：警告：NetworkManager在192.168.100.101,192.168.100.102上处于活动状态。OpenStack组网目前不支持启用Network Manager服务的系统。

第二章：Packstack 安装前准备

2.1 软件仓库配置

控制节点仓库配置

2.3 时间同步配置

注意：Linux 8 版本开始默认不再支持 ntpdate 工具，换用 chronyd 进行同步

控制节点时间同步配置

[root@controller01 ~]# vim /etc/chrony.conf# 修改内容如下：
#pool 2.centos.pool.ntp.org iburst  # 注释掉
pool ntp.aliyun.com iburst  # 添加
allow 192.168.100.0/24  # 用于允许指定网络段的设备通过NTP协议与本机时间服务器同步时间

计算节点时间同步配置

[root@compute02 ~]# vim /etc/chrony.conf# 修改内容如下：
#pool 2.centos.pool.ntp.org iburst   # 注释此行
pool controller01 iburst   # 添加此行

第三章：Packstack 安装配置

3.1 安装 Packstack 工具
[root@controller01 ~]# yum install -y openstack-packstack
3.2 生成应答文件
[root@controller01 ~]# packstack -h |grep ans--gen-answer-file=GEN_ANSWER_FILEGenerate a template of an answer file.--validate-answer-file=VALIDATE_ANSWER_FILECheck if answerfile contains unexpected options.--answer-file=ANSWER_FILEanswerfile will also be generated and should be used-o, --options         Print details on options available in answer file(rstPackstack a second time with the same answer file andattribute where "y" means an account is disabled.--manila-netapp-transport-type=MANILA_NETAPP_TRANSPORT_TYPEThe transport protocol used when communicating with[root@controller01 ~]# packstack  --gen-answer-file=response.txt
Packstack changed given value  to required value /root/.ssh/id_rsa.pub
Additional information:* Parameter CONFIG_NEUTRON_L2_AGENT: You have chosen OVN Neutron backend. Note that this backend does not support the VPNaaS plugin. Geneve will be used as the encapsulation methodor tenant networks

3.3 编辑应答文件

重要提示：注意设置参数 CONFIG_NEUTRON_OVN_BRIDGE_IFACES，OVN 会自动创建 br-ex 虚拟交换机并使 ens160 桥接到 br-ex 虚拟交换机上，未来云主机通过 br-ex 可以连通外部网络。

[root@controller01 ~]# vim response.txt# 修改以下参数内容：
CONFIG_COMPUTE_HOSTS=192.168.100.101,192.168.100.102
CONFIG_KEYSTONE_ADMIN_PW=redhat  # 此处是登录openstack网页后密码，用户是admin
CONFIG_PROVISION_DEMO=n
CONFIG_HEAT_INSTALL=y
CONFIG_NEUTRON_OVN_BRIDGE_IFACES=br-ex:ens160
3.4 执行安装

第四章：安装验证与后续配置

4.1 登录验证

4.2 启用 network 服务

说明：因关闭 NetworkManager 服务，会导致节点重启后网络无法自动启用，也会导致 OpenStack 组件异常，所以启用 network 来替代 NetworkManager 服务。

控制节点启用 network

[root@controller01 ~]# systemctl start network
[root@controller01 ~]# systemctl enable network

计算节点启用 network

[root@compute02 ~]# systemctl start network
[root@compute02 ~]# systemctl enable network[root@compute02 ~]# systemctl status network
