一.准备工作
云平台需要两个节点，一个controller（控制节点），一个compute（计算节点）环境要求：VM虚拟机2台，镜像为centos7或7.5。
本指南使用的ip
控制节点(controller)：
一块100G的硬盘。两块网卡，两块网卡第一块网卡IP地址为192.168.100.10，第二块网卡IP地址为192.168.200.10。（编辑时用的是60G硬盘）
计算节点(compute)：
一块100G硬盘和一块50G硬盘。两块网卡第一块网卡IP地址为192.168.100.20，第二块网卡IP地址为192.168.200.20。（编辑时用的60G+20G两块硬盘）
本指南运用的镜像
1.通过百度网盘分享的文件：CentOS-7-x86_64-DVD-2009.iso
链接：https://pan.baidu.com/s/1VqYqutsstDwdt7w8g4tjjg
提取码：dy7c
2.通过百度网盘分享的文件：CentOS-7.5-x86_64-DVD-1804.iso
链接：https://pan.baidu.com/s/1pzt1_iZ0Lph69Llvo_2ILQ
提取码：37ss
3.通过百度网盘分享的文件：chinaskills_cloud_iaas.iso
链接：https://pan.baidu.com/s/1EDlE-9bH83yGmvQtifLlvw
提取码：2e16
二.配置虚拟机
1.controller控制节点
重启后使用root登录，修改主机名，网卡
1.修改controller（控制节点）主机名
2.1修改第一块网卡
按insert进入编辑模式，编辑完后esc加冒号wq保存退出
2.2修改第二块网卡
重启网卡，使网卡生效
ip a查看一下是不是改好了
使用finalshell连接controller（为了更好的使用）
2.compute节点
第一块网卡配置如下：
第二块网卡配置如下：
重启网卡使配置生效
注意：compute节点也需要连接finalshell
三.正式开始搭建openstack云平台
controller节点配置：
1.上传centos7镜像和iaas镜像
上传成功！
2.关闭防火墙和selinux
systemctl stop firewalld #关闭防火墙
systemctl disable firewalld #防火墙开机不自启动
setenforce 0 #临时关闭selinux防火墙，1为打开
getenforce #查看selinux状态
更改selinux配置文件，非临时性关闭
vi /etc/selinux/config
3.挂载镜像
[root@controller ~]# mount -o loop CentOS-7-x86_64-DVD-1804.iso /mnt/
mount: /dev/loop0 写保护，将以只读方式挂载
[root@controller ~]# mkdir /opt/centos
[root@controller ~]# mkdir /opt/openstack
[root@controller ~]# cp -rf /mnt/* /opt/centos/
[root@controller ~]# umount /mnt/
[root@controller ~]# mount -o loop chinaskills_cloud_iaas.iso /mnt/
mount: /dev/loop0 写保护，将以只读方式挂载
[root@controller ~]# cp -rf /mnt/* /opt/openstack
[root@controller ~]# umount /mnt/4.yum文件处理
移除所有yum源
[root@controller ~]# cd /etc/yum.repos.d/
[root@controller yum.repos.d]# mv * /media/
[root@controller yum.repos.d]# ls
[root@controller yum.repos.d]#写yum源文件

1.关闭防火墙和selinux
[root@compute ~]# systemctl stop firewalld
[root@compute ~]# systemctl disable firewalld
[root@compute ~]# setenforce 0更改selinux配置文件，非临时性关闭
vi /etc/selinux/config
2.硬盘分区
[root@compute ~]# fdisk /dev/sdb
欢迎使用 fdisk (util-linux 2.23.2)。
更改将停留在内存中，直到您决定将更改写入磁盘。
使用写入命令前请三思。

四.刷脚本
注：刷脚本前可以快照
controller节点：
[root@controller ~]# iaas-pre-host.sh #刷完该脚本后需要重启
[root@controller ~]# iaas-install-mysql.sh
[root@controller ~]# iaas-install-keystone.sh
[root@controller ~]# source /etc/keystone/admin-openrc.sh #使环境生效
[root@controller ~]# iaas-install-glance.sh
[root@controller ~]# iaas-install-nova-controller.sh
[root@controller ~]# iaas-install-neutron-controller.sh
[root@controller ~]# iaas-install-dashboard.sh看到此类问题可以删除yum里除local.repo多余文件
直到出现以下：
compute节点：
[root@compute ~]# iaas-pre-host.sh #刷完该脚本后需要重启
[root@compute ~]# iaas-install-nova-compute.sh
[root@compute ~]# iaas-install-neutron-compute.sh
