Openstack是一个云平台管理的项目，它不是一个软件。这个项目由几个主要的组件组合起来完成一些具体的工作。Openstack是一个旨在为公共及私有云的建设与管理提供软件的开源项目。

一、安装环境

1.无网络使用该命令

nmcli c reload; sleep 3; nmcli c up ens33

2.修改主机名

hostnamectl set-hostname openstack.alione.loca

3.配置hosts解析

vim /etc/hosts

192.168.241.11 openstack openstack.alione.local

4.配置本机免密

生成密钥

ssh-keygen

对本机进行免密

ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.241.11

5.关闭防火墙和SElinux策略

sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config; setenforce 0; systemctl stop firewalld; systemctl disable firewalld

6.关闭NewworkManager

Centos7中有两种网络模式，避免冲突，在安装完OpenStack后开启

systemctl stop NetworkManager; systemctl disable NetworkManager

7.修改yum源

7.1下载阿里源

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

7.2清空并加载缓存yum源

yum clean all; yum makecache

8.安装基本工具

yum install -y bash-completion vim telnet bridge-utils yum-utils

bash

9.系统升级

yum -y update

reboot

10.安装OPenStack的yum仓库

yum install centos-release-openstack-train -y

11.修改OPenStack仓库Repo文件

cd /etc/yum.repos.d

cp CentOS-OpenStack-train.repo{,.bak}

vim CentOS-OpenStack-train.repo

baseurl=http://mirrors.aliyun.com/$contentdir/$releasever/cloud/$basearch/openstack-train/

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=cloud-openstack-train

yum clean all; yum makecache

12.安装PackStack工具

yum install -y openstack-packstack

13.安装OpenStack-allinone

packstack --allinone

二、安装完成后步骤

如下图：安装完成后会显示web登陆地址，http://192.168.241.11/dashboard

账号密码在：keystonerc_admin这个文件夹中

三、基本操作命令

source keystonerc_admin

 glance image-list

neutron agent-list

 nova service-list

 cinder service-list

1.数据库
