Openstack快速安装：packstack

0x80 前言

我曾经在差不多两年前安装过Openstack，当时是按照某个论坛的大牛的分享，一步一个脚印，用了很长时间才进入Openstack DashBoard并进行自己劳动成果的体验，感受自己为自己提供的服务。但是那次血泪安装史也并不完美，虽然核心组件成功运行，但是仍旧有部分功能存在问题，迫于精力有限，我便没有再碰过Openstack。
最近又心血来潮想要玩一玩这个曾经的玩物，恰巧了解到Openstack可以近乎一键安装，于是便再次操弄起来。

这里要特别感谢《Linux就该这么学》的主题网站，两年前的论坛我是记不住了，但这个网站我个人觉得是非常适合参照学习来提升个人能力的。第22章 使用openstack部署云计算服务环境。 | 《Linux就该这么学》

0x81 安装准备

处于学习目的，我使用的资源都是这篇教程的网站提供的。再次感谢让我有一次轻松学习部署Openstack的机会。软件资源库 | 《Linux就该这么学》

0x82 RHEL 7 安装

和安装一般的虚拟机一样，但是我们需要添加两块虚拟硬盘，其中一块提供给Openstack的Cinder使用。内存至少4GB（这里坑了我好久，第一次是horizon配置失败，后来不定时的发生错误，经过监视CPU和内存的使用才发现根本原因是内存不够，我分配4G只有3.8可用，最高占用达到过3.77G），虚拟网卡至少要有一个方便主机直接控制虚拟机的，比如Host-Only模式，当然要链接外网下载Package的话可以再分一块NAT，我直接使用的桥接（我是在Virtual Box中完成的）。

0x83 软件源的配置

linuxprobe.com提供的镜像默认repo是空的（貌似有一个EPEL和一个EPEL-Testing在线源），也就是说你不能安装任何软件包，所以我们要自己配置软件源。当然你可以直接配置在线软件源，由于所需的包那个网站都提供了，所以我配置的是离线仓库。

[root@openstack ~]# cat /etc/yum.repos.d/rhel.repo
[base]
name=base
baseurl=file:///media/cdrom
enabled=1
gpgcheck=0
[root@openstack ~]# cat /etc/yum.repos.d/epel.repo
[epel]
name=epel
baseurl=file:///media/EPEL
enabled=1
gpgcheck=0
[root@openstack ~]# cat /etc/yum.repos.d/openstack.repo
[openstack]
name=openstack
baseurl=file:///media/openstack-juno
enabled=1
gpgcheck=0

这样我们就可以安装常用的vim、net-tools等软件包了。

0x84 安装Openstack

我们先安装packstack工具:

yum install openstack-packstack

之后像执行部署工具：

packstack –allinone –provision-demo=n –nagios-install=n

这里不设置provision，也不安装nagios。等一切Apply完成，显示如下结果
