系统说明

服务器操作系统：Centos7

开发环境：VMware workstation Pro

OpenStack版本：stein

操作步骤

备份yum源

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

下载新的 CentOS-Base.repo 到 /etc/yum.repos.d/

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

运行 yum makecache 生成缓存

yum -y update

使用packstack 工具一键部署openstack

修改cento系统的主机名

hostnamectl set-hostname openstack

添加主机hosts记录

echo "172.17.2.60 openstack" >> /etc/hosts #将172.17.2.60修改为自己的虚拟机IP
echo "172.17.2.60 openstack.localdomain" >> /etc/hosts #将172.17.2.60修改为自己的虚拟机IP

验证修改结果

more /etc/hosts

设置本机SSH免密码登录

生成ssh密钥

ssh-keygen
ssh-copy-id root@172.17.2.60 #将172.17.2.60修改为自己的虚拟机IP

关闭服务

关闭防火墙

systemctl stop firewalld
systemctl disable firewalld

关闭SeLinux

sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config

关闭NetworManager服务

systemctl stop NetworkManager
systemctl disable NetworkManager

重启

reboot

安装常用软件

yum -y install vim bash-completion yum-utils

修改OpenStack配置文件

移除原系统自带的repo文件，避免和新建的配置文件内容冲突

mkdir ori_repo-config
mv /etc/yum.repos.d/* ./ori_repo-config/
touch /etc/yum.repos.d/CentOS-PrivateLocal.repo
vi /etc/yum.repos.d/CentOS-PrivateLocal.repo

将下列代码复制到CentOS-PrivateLocal.repo文件中

或者更换其他源

#清华大学源
curl -o /etc/yum.repos.d/CentOS-PrivateLocal.repo https://mirror.wjcloud.top/CentOS-PrivateLocal-qinghua.repo
#中科大源
curl -o /etc/yum.repos.d/CentOS-PrivateLocal.repo https://mirror.wjcloud.top/CentOS-PrivateLocal-zkd.repo

清除本地yum索引缓存，然后再重建索引缓存

yum clean all 
yum makecache

安装packstack工具

yum -y install openstack-packstack

一键安装openstack

packstack --allinone

等待20分钟后安装完成

访问http://虚拟机IP/

查看密码

cat /root/keystonerc_admin

export OS_USERNAME=admin #用户名

export OS_PASSWORD='625d45e5c2bb4330' #密码

一键部署命令

curl -sSL https://mirror.wjcloud.top/quick-openstack.sh -o quick-openstack.sh && sh quick-openstack.sh
