VirtualBox+Centos7 安装openstack之路

VirtualBox----Centos7系统下安装openstack

 

Centos7下安装openstack有很多种办法，最简单的是官方提供的，利用RDO安装。RDO的官方网站www.rdoproject.org。可以去看看。Centos7下利用RDO安装openstack只需要简单的四个命令，即可完成安装，省去一个一个服务独立安装的麻烦。

安装之前的要求：

机器至少有16GB内存（如果虚拟机，分配给虚拟机的内存最少16）

禁用防火墙和NetworkManager，命令如下：

$ sudo systemctl disable firewalld

$ sudo systemctl stop firewalld

$ sudo systemctl disable NetworkManager

$ sudo systemctl stop NetworkManager

$ sudo systemctl enable network

$ sudo systemctl start network

关于内存的要求，不确定是不是必须。本人4 5 6 7 8个G都试过，都没有成功，最后一怒变成16个G，一下就成功了，大家可以测试。

第1步：软件存储库

在红帽系统上，下载并安装RDO存储库RPM以设置OpenStack存储库：

$ sudo yum install -yhttps://rdoproject.org/repos/rdo-release.rpm

在CentOS上，Extras存储库提供了启用OpenStack存储库的RPM。Extras在CentOS 7上默认启用，所以你可以简单地安装RPM来设置OpenStack存储库。

$ sudo yum install -ycentos-release-openstack-pike

确保存储库已启用：

yum-config-manager --enableopenstack-pike

更新您的当前包：

$ sudo yum update -y

第2步：安装Packstack安装程序

$ sudo yum install -yopenstack-packstack

 

步骤3：运行Packstack安装OpenStack

Packstack不需要手动设置OpenStack。对于单节点OpenStack部署，请运行以下命令：

$ sudo packstack –allinone

 

 

备注及安装中的问题经验：

1.如果你以前运行过Packstack，那么你的主目录中会有一个文件名为packstack-answers-20130722-153728.txt你可能想再次使用该文件，使用该--answer-file选项，以便你已经设置的任何密码（例如，mysql）将被重用。

如$sudo packstack --answer-file=packstack-answers-20130722-153728.txt

文件名根据自己电脑/root/下面的实际名字写。

 

2.在安装过程中，到了Testing ifpuppet apply is finished:……….. 你的ip_compute.pp这里会卡主，等待他完成即可。

 

3.在安装过程中，可能会出现下载包失败。可能是因为centos源在国外，下载失败很正常，可以对上面的命令反复实验。本人脸黑，反复实验都失败了，最后一怒，换成了163的源，在执行安装命令packstack –allinone成功

更换源的方法，百度上有很多，本人使用的是以下几个命令：

$ mv /etc/yum.repos.d/CentOS-Base.repo/etc/yum.repos.d/CentOS-Base.repo.backup

$ wget -O/etc/yum.repos.d/CentOS-Base.repohttp://mirrors.163.com/.help/CentOS7-Base-163.repo

$ yum clean all

$ yum makecache

 

4.最后来一张openstack安装成功的截图，太难得了，走了很多坑

[root@localhost ~]# packstack --allinone
