目标:

1研究核心组件nova,neutron,cinder,ironic原理
2安装openstack queen版本

零、环境

1)win10中安装VMware-workstation-full-15.0.2
2)VMware中通过CentOS-7-x86_64-DVD-1511.iso安装Centos虚机
该Centos虚机配置信息如下面截图所示:

3)在该Centos虚机中通过packstack安装openstack queen版本

一、安装openstack

1 设置语言环境

vi /etc/environment 添加如下内容

LANG=en_US.utf-8
LC_ALL=en_US.utf-8

2 设置网络相关信息

禁用firewalld、NetworkManager　

sudo systemctl disable firewalld
sudo systemctl stop firewalld
sudo systemctl disable NetworkManager
sudo systemctl stop NetworkManager
sudo systemctl enable network
sudo systemctl start network

sudo vi /etc/selinux/config 修改SELINUX=disabled
sudo setenfore 0

3 安装openstack queens版本

yum install -y centos-release-openstack-queens
yum install -y epel-release
yum -y install openstack-packstack python-pip
packstack --allinone

5 遇到的问题以及解决的方法

1)

Testing if puppet apply is finished: 192.168.5.128_controller.pp [ / ]

192.168.5.128_controller.pp: [ ERROR ]
Applying Puppet manifests [ ERROR ]

ERROR : Error appeared during Puppet run: 192.168.5.128_controller.pp
Error: Execution of '/usr/bin/yum -d 0 -e 0 -y install openstack-cinder' returned 1: Error downloading packages:
You will find full trace in log /var/tmp/packstack/20210219-111444-YvVh1d/manifests/192.168.5.128_controller.pp.log
Please check log file /var/tmp/packstack/20210219-111444-YvVh1d/openstack-setup.log for more information
Additional information:

解决方法:
根据报错信息为 /usr/bin/yum -d 0 -e 0 -y install openstack-cinder 下载失败
实际上是因为安装的时候没有安装epel-release，导致openstack-cinder 安装失败
执行:
yum -y install epel-release
然后继续执行:
/usr/bin/yum -d 0 -e 0 -y install openstack-cinder
然后执行:

packstack --allinone

2)安装时卡在 Testing if puppet apply is finished: 192.168.5.128_controller.pp [ - ]

原因:
需要关闭之前说的防火墙
解决方法：
先停止 packstack --allinone的安装，然后执行如下命令:
systemctl stop firewalld && systemctl disable firewalld
systemctl stop NetworkManager && systemctl disable NetworkManager
packstack --allinone

3) 登录openstack界面报错

登录Openstack界面网址报internal 错误
后查看horizon的错误日志:
cd /var/log/httpd
cat horizon_error.log
报错信息如下：
