本篇文章是通过最新发布的Red Hat Enterpise Linux 7 系统部署OpenStack，集成到RHEL系统的OpenStack 简称为RDO。此篇是通过制作应答文件answer.conf自动化部署OpenStackIcehouse 版本。 由于采用RHEL7系统在部署中或多或少碰到不少报错的问题，这里只列出我的几张截图，在部署中还是需要根据实际情况来决定，多看下报错及日志文件；例如：解决包的依赖，，服务不能没有启动起来，数据库密码设置未成功等；希望本篇可以给部署RDO的同学带来一定的帮助。关于RHEL7安装，同学可以参见早期的最新RHEL7安装体验：好了，详情见正文吧！
1.制作本地YUM及安装最新RHEL7-Epel
[root@wwwyum.repos.d]#mount-oloopRHEL-7.0-20140305.0-Server-x86_64-dvd1.iso/mnt/[root@wwwyum.repos.d]#catrhel7.repo[rhel7]name=rhel7baseurl=file:///mntenable=1gpgcheck=0gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-releaseskip_if_unavailable=1keepcache=0[root@wwwyum.repos.d]#wget…se-7-0.2.noarch.rpm[root@wwwyum.repos.d]#rpm-ivhepel-release-7-0.2.noarch.rpm[root@wwwyum.repos.d]#yumcleanall[root@wwwyum.repos.d]#yummakecache
2.设置RDO存储库
[root@wwwyum.repos.d]#yuminstall-y[root@wwwyum.repos.d]#catrdo-release.repo[openstack-icehouse]name=OpenStackIcehouseRepositorybaseurl=http://repos.fedorapeople.org/repos/openstack/openstack-icehouse/epel-7/enabled=1skip_if_unavailable=0gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-RDO-Icehousepriority=98
3.安装packstack

4.生成自动化部署配置文件
[root@wwwyum.repos.d]#packstack–gen-answer-file=answer.conf
5.answer.conf 文件细节过滤空行及注释行内容， 这里就不一一说明每个参数的含义了，基本通过查看配置参数的关键都可以明白其含义， 也可参考我此篇文章 中的localrc 的描述
一切都在发展变化，不断地向昨天告别，满怀信心地投入每一个崭新的今天。
