CentOS Stream 8 通过 Packstack 安装开源 OpenStack（V版）

需要了解

• 虚拟化平台版本 VMware Workstation 16.2.3
• 操作系统版本 CentOS Linux Stream 8
• 安装源您可访问 阿里永久镜像站 / 华为永久镜像站 或其他镜像站进行下载
• 环境用到 2台 虚拟机，单网卡，并为其配置 静态 IP 及 DNS
• 从 Ussuri 版本开始，需要使用 CentOS 8 或 RHEL 8，截至发稿前，Stream 8 版本支持的最高版本为 xena
• 搭建 openstack 最麻烦的是 yum 源问题，建议严格按照本篇博客进行 yum 源配置操作
• 保姆级别，按照步骤操作，绝对一次性安装成功。

环境规划

控制节点及计算节点必须开启虚拟化引擎 Intel VT-x 或 AMD-V。控制节点未来将被复用为计算节点和网络节点。虚拟机配置可根据实际情况进行调整。

系统环境配置

网络配置

当前环境中控制节点及计算节点网卡类型为 NAT

网卡配置、关闭防火墙、Selinux、NetworkManager

• 控制节点

### 网卡配置

[root@tmp ~]# hostnamectl set-hostname controller
[root@tmp ~]# hostname
controller

[root@tmp ~]# cd /etc/sysconfig/network-scripts/
[root@tmp network-scripts]# ls
ifcfg-ens160
[root@tmp network-scripts]# vi ifcfg-ens160 
[root@tmp network-scripts]# cat ifcfg-ens160 
TYPE=Ethernet
BOOTPROTO=none
NAME=ens160
DEVICE=ens160
ONBOOT=yes
IPADDR=192.168.129.185
NETMASK=255.255.255.0
GATEWAY=192.168.129.2
DNS1=192.168.129.2

### 可以再配置完ip之后关机拍摄快照

### 关闭防火墙
[root@controller ~]# systemctl stop firewalld
[root@controller ~]# systemctl disable firewalld
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

### 关闭SELINUX
[root@controller ~]# setenforce 0
[root@controller ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

### 关闭NetworkManager
[root@controller ~]# systemctl stop NetworkManager
[root@controller ~]# systemctl disable NetworkManager
Removed /etc/systemd/system/multi-user.target.wants/NetworkManager.service.
Removed /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.
Removed /etc/systemd/system/network-online.target.wants/NetworkManager-wait-online.service.

• 计算节点

### 网卡配置

[root@tmp ~]# hostnamectl set-hostname computer
[root@tmp ~]# hostname
computer

[root@tmp ~]# cd /etc/sysconfig/network-scripts/
[root@tmp network-scripts]# ls
ifcfg-ens160
[root@tmp network-scripts]# vi ifcfg-ens160 
[root@tmp network-scripts]# cat ifcfg-ens160 
TYPE=Ethernet
BOOTPROTO=none
NAME=ens160
DEVICE=ens160
ONBOOT=yes
IPADDR=192.168.129.186
NETMASK=255.255.255.0
GATEWAY=192.168.129.2
DNS1=192.168.129.2
[root@tmp network-scripts]# 

### 可以再配置完ip之后关机拍摄快照

根据实际情况给处理器

### 关闭防火墙
[root@computer ~]# systemctl stop firewalld
[root@computer ~]# systemctl disable firewalld
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

### 关闭SELINUX
[root@computer ~]# setenforce 0
[root@computer ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

### 关闭NetworkManager
[root@computer ~]# systemctl stop NetworkManager
[root@computer ~]# systemctl disable NetworkManager
Removed /etc/systemd/system/multi-user.target.wants/NetworkManager.service.
Removed /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.
Removed /etc/systemd/system/network-online.target.wants/NetworkManager-wait-online.service.

配置ip及主机名安装基础包

• 控制节点

### 配置ip及主机名
[root@controller ~]# vi /etc/hosts
[root@controller ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.129.185 controller
192.168.129.186 computer

[root@controller ~]# ping computer

### 安装基础包
[root@controller ~]# yum install -y vim net-tools bash-completion chrony.x86_64 centos-release-openstack-victoria.noarch

• 计算节点

### 配置ip及主机名
[root@computer ~]# vi /etc/hosts
[root@computer ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.129.185 controller
192.168.129.186 computer
[root@computer ~]# ping controller

### 安装基础包
[root@computer ~]# yum install -y vim net-tools bash-completion chrony.x86_64 centos-release-openstack-victoria.noarch

如果在安装基础包出错，重启之后没有ip，可以重启 NetworkManager，再讲其关闭

NTP时间同步配置

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

[root@controller ~]#  vi /etc/chrony.conf

# Please consider joining the pool (http://www.pool.ntp.org/join.html).
#pool 2.centos.pool.ntp.org iburst
sever  pool ntp.aliyun.com iburst     ### 配置了阿里云ntp

# Record the rate at which the system clock gains/losses time.
driftfile /var/lib/chrony/drift
..............

### 启动服务
[root@controller ~]# systemctl start chronyd.service
Job for chronyd.service failed because the control process exited with error code.
See "systemctl status chronyd.service" and "journalctl -xe" for details.
[root@controller ~]# systemctl enable chronyd.service

• 计算节点

[root@computer ~]# vi /etc/chrony.conf

# Please consider joining the pool (http://www.pool.ntp.org/join.html).
#pool 2.centos.pool.ntp.org iburst
sever  pool ntp.aliyun.com iburst     ### 配置了阿里云ntp

driftfile /var/lib/chrony/drift
..............

### 启动服务
[root@computer ~]# systemctl start chronyd.service
Job for chronyd.service failed because the control process exited with error code.
See "systemctl status chronyd.service" and "journalctl -xe" for details.
[root@computer ~]# systemctl enable chronyd.service

配置YUM源

• 控制节点

[root@controller ~]# mkdir /etc/yum.repos.d/bak
[root@controller ~]# mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/bak/

[root@controller ~]# cat <<EOF > /etc/yum.repos.d/cloudcs.repo

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 method for tenant networks
 * Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.
 * File /root/keystonerc_admin has been created on OpenStack client host 192.168.129.185. To use the command line tools you need to source the file.

开启network

• 控制节点

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。

[root@controller ~]# systemctl enable network
network.service is not a native service, redirecting to systemd-sysv-install.
Executing: /usr/lib/systemd/systemd-sysv-install enable network
[root@controller ~]# systemctl start  network

• 计算节点

[root@computer ~]# systemctl enable network
network.service is not a native service, redirecting to systemd-sysv-install.
Executing: /usr/lib/systemd/systemd-sysv-install enable network
[root@computer ~]# systemctl start  network

• 补充

• 在使用 Packstack 工具搭建 OpenStack 时需要关闭 NetworkManager 而开启并使用network，主要是因为OpenStack 环境对网络的要求和配置与NetworkManager的工作方式不太适配NetworkManager是一个用于图形和命令行环境下的网络管理工具，旨在为桌面用户提供便捷的网络配置。它能够处理各种网络类型，包括有线、无线、蓝牙等，并根据网络环境进行动态管理。然而，在 OpenStack 环境中，网络需求通常更加复杂，需要更多的控制和自定义。
• OpenStack是一个用于搭建云基础设施的开源平台，涉及到多个虚拟机、网络、存储等组件的配置和管理。在 OpenStack 环境中，网络通常需要进行高度定制和精细控制，以满足不同的租户和应用场景的需求。这与 NetworkManager 提供的自动化和动态网络管理方式不太吻合。
• 而采用传统的 network 服务，您可以更精确地配置和管理网络接口、IP 地址、路由等参数以满足OpenStack环境中的复杂网络需求。这对于创建虚拟网络、隔离租户、实现网络互通等 OpenStack 功能非常重要。
• 因此，为了确保 OpenStack 环境的网络配置能够精确地满足其需求，通常会建议在搭建OpenStack 时关闭 NetworkManager，使用传统的 network 服务来进行网络配置。这样可以更好地控制和调整网络参数，以确保 OpenStack 网络的稳定性和性能
