RDO一体化部署openstack实验心得 rdo安装openstack

OpenStack介绍

openstack详细介绍及常用命令请查看此文

通过Packstack(RDO)部署OpenStack，官方文档点击此处查看

安装环境

• 工具：VMware Workstation 16 Pro
• 操作系统：CentOS 8.3
• 虚拟机配置

• 内存 8G
• 处理器 6C
• 磁盘 120G
• 虚拟化引擎
  以上配置非最低要求，可根据实际情况尝试安装

基础配置

1. 配置环境
   编辑vim /etc/environment文件，添加以下内容

LANG=en_US.utf-8
LC_ALL=en_US.utf-8

安装en_US.utf-8语言包

dnf install glibc-langpack-en -y

1. 设置主机名并配置/etc/hosts文件
   修改主机名

hostnamectl set-hostname duan
exec bash

使用echo命令，在/etc/hosts文件中添加本地解析，或者通过vim命令添加

echo -e "192.166.66.6\tduan" >> /etc/hosts

1. 关闭防火墙并禁止开机自启

systemctl disable firewalld && systemctl stop firewalld

1. 更换网络服务
   在安装部署OpenStack时，OpenStack的网络服务会与NetworkManager服务产生冲突，二者无法一起正常工作，需要使用Network

# 安装Network服务
dnf install network-scripts -y
# 停用NetworkManager并禁止开机自启
systemctl stop NetworkManager && systemctl disable NetworkManager
# 启用 Network并设置开机自启
systemctl start network && systemctl enable network

更换网络后，远程连接工具可能会断开，建议reboot重启系统，IP可能会发生变化，请查看IP后重新连接远程工具

1. 设置静态IP
   编辑网络配置文件

vim /etc/sysconfig/network-scripts/ifcfg-ens33

修改修改并添加以下内容

# 设为静态
BOOTPROTO=static
# 设为开机自动连接
ONBOOT=yes
# 添加IP、子网掩码及网关
IPADDR=192.166.66.6
NETMASK=255.255.255.0
GATEWAY=192.166.66.2

重启Network网络服务

# 重启网络服务
systemctl restart network
# 测试是否可访问外网
ping -c 5 www.baidu.com

OpenStack安装

1. 启用powertools存储库并安装Victoria版openstack

dnf config-manager --enable powertools
dnf install centos-release-openstack-victoria -y

1. 更新当前软件包

dnf update -y

1. 安装paskstack工具

dnf install openstack-packstack -y

1. 使用packstack命令安装openstack

packstack --allinone

安装进度由当前网络环境决定，请耐心等待……，此次安装耗时1小时左右

安装成功会出现“Installation completed successfully”提示，如下

[root@duan ~]# packstack --allinone

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
 * A new answerfile was created in: /root/packstack-answers-20210225-204841.txt
 * 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 192.166.66.6. To use the command line tools you need to source the file.
 * To access the OpenStack Dashboard browse to http://192.166.66.6/dashboard .

1. 通过生成的链接http://192.166.66.6/dashboard访问OpenStack仪表板

登录账号密码在keystonerc_admin文件中查看

登录成功页面

之后就可以使用界面自己玩耍啦，创建卷、快照、镜像、网络、安全组，又或者项目、角色、用户等尽情尝试吧！

当然也可以使用openstack命令

使用命令前需要加载环境变量，执行命令source keystonerc_admin或. keystonerc_admin

在安装过程中有出现报错：ERROR : Error appeared during Puppet run: 192.166.66.6_controller.pp，导致安装终止，这个报错原因多半是没有/etc/hosts文件中添加本地解析导致，也可能是网络问题，若完全按照上面步骤操作依然出现此报错，建议更换网络试一下
