前言

一：部署 OpenStack

1.1：环境

VMware软件
一台centos7虚拟机作为OpenStack控制节点，NAT的IP地址：192.168.233.102

1.2：实验目的

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

1.3：实验过程

1.3.1：安装虚拟机

过程简单，不在赘述，配置如下（最小化安装即可）

1.3.2：IP地址配置与修改主机名

[root@localhost ~]# hostnamectl set-hostname openstack	'//修改主机名'
[root@localhost ~]# su
[root@openstack ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33	'//修改网卡IP地址' 
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static	'//原本的dhcp修改为static'
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=abae53a8-d784-4ddb-bacb-4c58fe637d0f
DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.233.102	'//添加以下IP地址信息'
NETMASK=255.255.255.0
GATEWAY=192.168.233.2
[root@openstack ~]# systemctl restart network	'//重启网卡'
[root@openstack ~]# vi /etc/hosts	'//修改主机映射文件'
192.168.233.102 localhost.localdomain
[root@localhost ~]# vim /etc/resolv.conf	'//修改域名解析文件'
那么server 8.8.8.8
[root@openstack ~]# ping 8.8.8.8	'//ping域名服务器	'
[root@openstack ~]# ping www.baidu.com	'//ping百度'

1.3.3：开局优化

关闭防火墙与和信访防护，并取消开机自启动

[root@openstack ~]# systemctl stop firewalld	'//关闭防护墙'
[root@openstack ~]# systemctl disable firewalld	'/取消开机自启动'
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@openstack ~]# setenforce 0	'//关闭核心防护'
[root@openstack ~]# vi /etc/sysconfig/selinux	'//取消开机自启'
SELINUX=disabled

关闭网络管理工具，取消开机自启

[root@openstack ~]# systemctl disable NetworkManager
Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.
Removed symlink /etc/systemd/system/network-online.target.wants/NetworkManager-wait-online.service.
[root@openstack ~]# systemctl stop NetworkManager

搭建时间同步

[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'

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

重启，查看服务是否正常
```
[root@openstack ~]# reboot
```

1.3.4：一键部署部署OpenStack

安装OpenStack-packstack软件包

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

在线部署

[root@OpenStack ~]# packstack --allinone 	'//大约等待30分钟左右'

查看用户和密码

[root@openstack ~]# ls
anaconda-ks.cfg  keystonerc_admin  keystonerc_demo  packstack-answers-20200227-100103.txt
[root@openstack ~]# cat keystonerc_admin 
unset OS_SERVICE_TOKEN
    export OS_USERNAME=admin	'//用户名为admin'
    export OS_PASSWORD='894111c1565f478d'	'//密码复制一下，稍后网页登陆使用'
    export OS_REGION_NAME=RegionOne
    export OS_AUTH_URL=http://192.168.233.102:5000/v3
