Openstack----（在线源）使用packstack工具一键部署OpenStack！

一：部署 OpenStack

1.1 环境

VMware软件
CentOS7.6最小化安装
NAT的IP地址：20.0.0.100

packstack 一键部署 OpenStack，登录OPenStack中的WEB页面进行操作。

1.2 安装虚拟机

最小化安装CentOS 7.6系统，CPU双核双线程/开启虚拟化功能
内存8G，硬盘40G+300G，网卡：NAT模式
修改网卡名为eth0：net.ifnames=0 biosdevname=0

1.2.1 IP地址配置与修改主机名

hostnamectl set-hostname openstack
bash
vi /etc/sysconfig/network-scripts/ifcfg-eth0
systemctl restart network	
vim /etc/resolv.conf	
nameserver 8.8.8.8
[root@openstack ~]# ping 8.8.8.8	
[root@openstack ~]# ping www.baidu.com	

1.2.2 初始化操作

1. 关闭防火墙与和核心防护，NetworkManager

[root@openstack ~]# systemctl stop firewalld	'//关闭防护墙'
[root@openstack ~]# systemctl disable firewalld	'/取消开机自启动'
[root@openstack ~]# setenforce 0	'//关闭核心防护'
[root@openstack ~]# vi /etc/sysconfig/selinux	'//取消开机自启'
SELINUX=disabled
systemctl stop NetworkManager

2. 关闭网络管理工具，取消开机自启

[root@openstack ~]# systemctl disable NetworkManager
[root@openstack ~]# systemctl stop NetworkManager

3. 创建时间同步

[root@openstack yum.repos.d]# yum -y install ntpdate	'//安装ntpdate服务'
[root@openstack yum.repos.d]# ntpdate ntp.aliyum.com >>/var/log/ntpdate.log	'//同步aliyum时间'
[root@openstack yum.repos.d]# crontab -e	'//创建周期计划任务'
*/30 * * * * /usr/sbin/ntpdate ntp.aliyum.com >>/var/log/ntpdate.log
[root@openstack yum.repos.d]# systemctl restart crond	'//重启计划任务'
[root@openstack yum.repos.d]# systemctl enable crond	'//设置开机自启动'

4. 编辑yum源，并安装train版OpenStack

[root@openstack ~]# cd /etc/yum.repos.d/
[root@openstack yum.repos.d]# mkdir bak
[root@openstack yum.repos.d]# mv C* bak/
[root@openstack yum.repos.d]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@openstack yum.repos.d]# yum -y install centos-release-openstack-train
[root@openstack yum.repos.d]# yum clean all
[root@openstack yum.repos.d]# yum makecache

5. 重启，查看服务是否正常

[root@openstack ~]# reboot

1.3 一键部署部署OpenStack

1. 安装OpenStack-packstack软件包

[root@OpenStack ~]# yum -y install openstack-packstack 

2. 在线部署

[root@OpenStack ~]# packstack --allinone 	'//等待20分钟左右'
