openstack安装

RDO（Red Hat Distribution of OpenStack）是由红帽公司推出的部署OpenStack集群的一个基于Puppet的部署工具，可以很快地通过RDO部署一套复杂的OpenStack环境。如果用户想在REHL上面部署OpenStack，最便捷的方式就是RDO。
环境：Centos7系统，4G内存，100G硬盘大小。

一：更新yum源

yum -y update

二：RDO安装源

yum install -y https://www.rdoproject.org/repos/rdo-release.rpm

三：在使用RDO安装OpenStack过程中，需要Packstack来部署OpenStack，以下安装Packstack：

yum install -y openstack-packstack

最好把相关依赖包都尽量安装下：

yum install -y yum openstack-packstack  openstack-nova-compute puppet hiera openssh-clients  tar nc rubygem-json openstack-nova-conductor openstack-dashboard openstack-swift mongodb-server  openstack-ceilometer-central mariadb  mariadb-galera-server python-openstackclient openstack-cinder openstack-liberty

四：关闭相应服务

systemctl disable NetworkManager-dispatcher.service
systemctl disable NetworkManager.service 
systemctl disable postfix.service
systemctl stop NetworkManager
systemctl status NetworkManager
systemctl list-unit-files |grep enable

这里必须停止 NetworkManager，不然一直卡起执行：

Testing if puppet apply is finished: 192.168.18.167_glance.pp

关闭SELINUX

/etc/selinux/config里设置

SELINUX=disabled

五：单节点快速部署OpenStack

packstack --allinone

正常应该如下过程：

[root@kilo-rdo ~]# packstack --allinone

 * Time synchronization installation was skipped. Please note that unsynchronize  
d time on server instances might be problem for some OpenStack components.  
 * File /root/keystonerc_admin has been created on OpenStack client host 192.168

 * To access the OpenStack Dashboard browse to http://192.168.80.128/dashboard .  
  
Please, find your login credentials stored in the keystonerc_admin in your home  
directory.  
 * To use Nagios, browse to http://192.168.80.128/nagios username: nagiosadmin,

六：登录OpenStack控制台：

查看控制台登录信息位于用户主目录的keystonerc_admin文件中。
可以用more keystonerc_admin命令查看登录。

遇到的问题：
开始用VPS测试的，但是一直卡在Testing if puppet apply is finished: 192.168.80.128_controller.pp  [ | ]  不走了。网上很多朋友好像也都遇到过，也没有给出解决方法，很无奈。
后来改用物理服务器就成功了，最需要等待时间的还是在Testing if puppet apply is finished: 192.168.80.128_controller.pp  [ | ] 这一步，服务器安装的时候大概等了将近一个小时。

总结，单节点快速安装其实也就是简单的四个命令：

yum update -y 
yum install -y https://rdoproject.org/repos/rdo-release.rpm 
yum install -y openstack-packstack 
packstack --allinone

最后一步安装过程如下：

[root@openstackline ~]# packstack --allinone
