一、部署packstack
1.1 简介
对于openstack初学者而言，传统部署openstack流程是在过于繁琐，需要多台虚拟机，packstack完美解决这个问题，可以减少了许多繁琐且容易出错的部署流程，packstack可以选择单节点或双节点部署，本次完美使用单节点部署allinone。
1.2 性能搭配
推荐处理器内核至少3个（i5-8300H四核八线程），尽量按你最大的核心分配，否则正式安装会很慢！！！内存推荐6G（4G应该也没问题）。
1.3 准备工作
1.关闭防火墙、SElinux、NetManager
2.时间同步
3.更换repo源
关闭防火墙
systemctl disable firewalld &&\
systemctl stop firewalld &&\
systemctl disable NetworkManager &&\
systemctl stop NetworkManager &&\
systemctl enable network &&\
systemctl start network
关闭SElinux
vi /etc/selinux/config
修改SELINUX=disabled
setenforce 0
同步时间ntpdate
yum install ntpdate -y
ntpdate ntp1.aliyun.com
systemctl enable ntpdate
date
1.4 安装
更换阿里云的repo源
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum makecache
安装openstack-queens，本质只是下载了Q版的repo源，在/etc/yum.repos.d/可以查看到repo源。
yum install -y centos-release-openstack-queens
yum update -y
正式安装
yum install -y openstack-packstack
正式部署
本机大概用了45分钟，此命令非常占用cpu，八代i5u，1cpu3内核也要45分钟，建议至少是这个配置，内存6G就行。因为我电脑只有4内核，所以没敢全给，之前2内核也是很久很久甚至没有成功。
packstack --allinone
安装成功，如果没有出现下列成功提示，请往下浏览，看看有没有我踩过的坑。

二、出现的问题
2.1 安装中断临时文件
/root下会生产多个临时安装文件，如果因为某些原因安装中断，可以使用answer继续上次的安装，嫌麻烦也可以不管，实际没有影响。

2.2 提示某个安装包出错
提示python2-qpid-proton-0.22.0-1.el7.x86_64安装包出错

尝试手动yum install安装，解决，如果是其它安装包也是同样的方法。
yum install -y python2-qpid-proton-0.22.0-1.el7.x86_64
2.3 leatherman版本太高
提示 facter: error while loading shared libraries: leatherman_curl.so.1.3.0: cannot open shared object file: No such file or directory，leatherman 1.3 版本过高，可以降为1.10 版本。

yum downgrade leatherman命令降级，已解决。
[root@openstack yum.repos.d]# yum list | grep leatherman
leatherman.x86_64 1.10.0-1.el7 @epel
leatherman-devel.x86_64 1.10.0-1.el7 epel
[root@openstack yum.repos.d]# yum downgrade leatherman
[root@openstack yum.repos.d]# yum list | grep leatherman
