利用packstack部署openstack(all in one的方式)

前言

正式工作了，方向由深度学习转为了云计算。以此来开启职业生涯的第一篇博文。

准备条件：虚拟机（centos7 、内存6g、硬盘40g、处理器4核并开启intel vt-x，网络模式设置为NAT，虚拟机网络一定要设置好，不然有中途掉IP的情况发生）

装好centos虚拟机后，在系统配置界面先配置好固定ip。以下命令均以root用户身份进行

1.换源

我这里使用的是阿里源

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

2.关闭防火墙等设置

systemctl disable firewalld  &&\
systemctl stop firewalld  &&\
systemctl disable NetworkManager &&\
systemctl stop NetworkManager &&\
systemctl enable network &&\
systemctl start network

3.seliunx设置

vi /etc/selinux/config 

修改SELINUX=disabled

setenforce 0

 

4.安装openstack queens版本库

yum install -y centos-release-openstack-queens

yum update -y

 

5.安装packstack库

 

yum install -y openstack-packstack

 

6.开始部署openstack

packstack -d --allinone

如果没有问题，正确的结果如下所示：

根据Additional information:

我们可以访问http://192.168.101.128/dashboard 进入OpenStack的管理界面，登录名和密码在用户目录的keystonerc_admin文件中：

 

 

 

 

 

在这最后一步中，最容易出问题，先将我碰到的问题总结如下，如有其它问题，大家可以评论区讨论分享：

leatherman版本过高

如下图

解决方案：降级leatherman 

yum downgrade leatherman 

该解决方案来源于：

Packstack安装OpenStack问题：facter: error while loading shared libraries: leatherman_curl.so.1.3.0

执行到如下卡死

Testing if puppet apply is finished: 192.168.101.128_controller.pp  [ \ ]

原因：这一步本身执行的时间就很久，耐心等待，我在这里，电脑放了一个晚上，大概几个小时候结果就出来了。如果还是不行的话，检查是否是自己的虚拟机配置设置得过低
