Openstack 一键安装部署 单节点

使用 packstack 工具实现一键部署 OpenStack。 通过该安装工具， 只需简单运行一条命令， 即可以快速部署 OpenStack， 省去繁琐的安装步骤， 而直接体验OpenStack 的管理及使用。 本案例需要提前部署一台新安装的操作系统主机， 要求能访问互联网， 主机的系统采用最小化方式安装即可。

内存要不低于8G，最好11G。本次实验虚拟机是11G内存
CPU核心数不得低于4核。本次实验虚拟机CPU核心4核

一，关闭防火墙并且安装RDO软件

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# setenforce 0
[root@localhost ~]# yum -y install http://rdo.fedorapeople.org/rdo-release.rpm

二，安装一个叫packstack的部署包

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

三，一键自动安装
注：这一步需要耐心等待很长一段时间

[root@localhost ~]# packstack --allinone

 * Parameter CONFIG_NEUTRON_L2_AGENT: You have chosen OVN Neutron backend. Note that this backend does not support the VPNaaS or FWaaS services. Geneve will be used as the encapsulation method for tenant networks
 * A new answerfile was created in: /root/packstack-answers-20200629-210711.txt
 * Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.
 * Warning: NetworkManager is active on 192.168.116.128. OpenStack networking currently does not work on systems that have the Network Manager service enabled.
 * File /root/keystonerc_admin has been created on OpenStack client host 192.168.116.128. To use the command line tools you need to source the file.
 * To access the OpenStack Dashboard browse to http://192.168.116.128/dashboard .
Please, find your login credentials stored in the keystonerc_admin in your home directory.

四，查看账户和密码

[root@localhost ~]# cat keystonerc_admin 
unset OS_SERVICE_TOKEN
    export OS_USERNAME=admin
    export OS_PASSWORD='c8327e23a69d4c0f'
    export OS_REGION_NAME=RegionOne
    export OS_AUTH_URL=http://192.168.116.128:5000/v3
    export PS1='[\u@\h \W(keystone_admin)]\$ '
    
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_IDENTITY_API_VERSION=3

安装完毕，可以通过OpenStack的网络管理接口Horizon进行访问，地址如：http://本机id/dashboard ，用户名为admin，密码可以在/root/keystonerc_admin文件中找到。
