安裝環境
-
工具：VMware Workstation 16 Pro
-
操作系統：CentOS 8.3
-
虛擬機配置
-
內存 8G
-
處理器 6C
-
磁盤 120G
-
虛擬化引擎
以上配置非最低要求，可根據實際情況嘗試安裝
-
基礎配置
-
配置環境
編輯
vim /etc/environment文件，添加以下內容LANG=en_US.utf-8 LC_ALL=en_US.utf-8
安裝en_US.utf-8語言包
dnf install glibc-langpack-en -y -
設置主機名並配置
/etc/hosts文件修改主機名
hostnamectl set-hostname duan exec bash使用echo命令，在/etc/hosts文件中添加本地解析，或者通過vim命令添加
echo -e "192.166.66.6\tduan" >> /etc/hosts
-
關閉防火牆並禁止開機自啟
systemctl disable firewalld && systemctl stop firewalld -
更換網絡服務
在安裝部署OpenStack時，OpenStack的網絡服務會與NetworkManager服務產生沖突，二者無法一起正常工作，需要使用Network
# 安裝Network服務 dnf install network-scripts -y # 停用NetworkManager並禁止開機自啟 systemctl stop NetworkManager && systemctl disable NetworkManager # 啟用 Network並設置開機自啟 systemctl start network && systemctl enable network更換網絡后，遠程連接工具可能會斷開，建議
reboot重啟系統，IP可能會發生變化，請查看IP后重新連接遠程工具 -
設置靜態IP
編輯網絡配置文件
vim /etc/sysconfig/network-scripts/ifcfg-ens33修改修改並添加以下內容
# 設為靜態 BOOTPROTO=static # 設為開機自動連接 ONBOOT=yes # 添加IP、子網掩碼及網關 IPADDR=192.166.66.6 NETMASK=255.255.255.0 GATEWAY=192.166.66.2
重啟Network網絡服務
# 重啟網絡服務 systemctl restart network # 測試是否可訪問外網 ping -c 5 www.baidu.com
OpenStack安裝
-
啟用
powertools存儲庫並安裝Victoria版openstackdnf config-manager --enable powertools dnf install centos-release-openstack-victoria -y -
更新當前軟件包
dnf update -y -
安裝paskstack工具
dnf install openstack-packstack -y -
使用packstack命令安裝openstack
packstack --allinone安裝進度由當前網絡環境決定，請耐心等待……，此次在出租屋里安裝耗時1小時左右
安裝成功會出現“Installation completed successfully”提示，如下

登錄賬號密碼在keystonerc_admin文件中查看
登錄成功頁面
之后就可以使用界面自己玩耍啦，創建卷、快照、鏡像、網絡、安全組，又或者項目、角色、用戶等盡情嘗試吧！
當然也可以使用openstack命令
使用命令前需要加載環境變量，執行命令
source keystonerc_admin或. keystonerc_admin
在安裝過程中有出現報錯：ERROR : Error appeared during Puppet run: 192.166.66.6_controller.pp，導致安裝終止，這個報錯原因多半是沒有/etc/hosts文件中添加本地解析導致，也可能是網絡問題，若完全按照上面步驟操作依然出現此報錯，建議更換網絡試一下
