OpenStack是一个开源的云计算管理平台项目,是一系列
软件开源项目的组合,OpenStack为私有云和公有云提供
可扩展的弹性的云计算服务,项目目标是提供实施简单,可
大规模扩展,丰富,标准统一的云计算管理平台。

1.环境配置
Centos7 4核8G
2.先关闭防火墙和selinux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
已安装:
  rdo-release.noarch 0:train-1                                                                                                                  
完毕!

3.安装packstack工具实现一键部署OpenStack

[root@localhost ~]# yum -y install openstack-packstack
作为依赖被升级:
libselinux.x86_64 0:2.5-15.el7  
libselinux-python.x86_64 0:2.5-15.el7
libselinux-utils.x86_64 0:2.5-15.el7
libsepol.x86_64 0:2.5-10.el7  
完毕!

4.一键自动安装(注:执行这条命令需要等待一段时间)

[root@localhost ~]# packstack --allinone

Additional information:
 * 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-20200630-211042.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 192.168.20.181. 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 192.168.20.181. To use the command line tools you need to source the file.
 * To access the OpenStack Dashboard browse to http://192.168.20.181/dashboard .
Please, find your login credentials stored in the keystonerc_admin in your home directory.
 * The installation log file is available at: /var/tmp/packstack/20200630-211041-FwAeNx/openstack-setup.log
 * The generated manifests are available at: /var/tmp/packstack/20200630-211041-FwAeNx/manifests

5.查看账号和密码

[root@localhost ~]# cat keystonerc_admin
unset OS_SERVICE_TOKEN
    export OS_USERNAME=admin  #账号
    export OS_PASSWORD='777f2993392948bb' #密码
    export OS_REGION_NAME=RegionOne
    export OS_AUTH_URL=http://192.168.20.181:5000/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

6.安装完毕后,可以通过浏览器访问,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。
