O01-Linux CentOS7中利用RDO部署OpenStack图文教程

时间:2018-03-21 23:22:44   收藏:0   阅读:3863

一、前言

1.RDO是红帽Red Hat 的一个开源项目,全称是RPM Distribution of OpenStack,能够帮助我们快捷部署OpenStack项目。

官方部署文档:https://www.rdoproject.org/install/packstack/

 

2.本次安装基本是完全按照官方文档的步骤来操作的,除了第二部分安装前环境准备中的第3点。本次部署的是单节点的实验环境,版本是最新稳定版Queens

另外,根据官方文档描述的,RDO也可用于部署多节点环境。

 

3.测试的环境:

工具:VirtualBox

操作系统:CentOS7

虚拟机配置:4核、6G内存、25G容量的硬盘空间。(官方推荐配置:Machine with at least 16GB RAM, processors with hardware virtualization extensions, and at least one network adapter.)

虚拟机IP:192.168.137.20(是静态IP且能连接外网,IP部署方法链接:http://www.cnblogs.com/suhaha/p/8619102.html

 

二、安装前的环境准备

1./etc/environment文件中配置环境变量

LANG=en_US.utf-8

LC_ALL=en_US.utf-8

 

2.关闭防火墙等一些网络服务

命令:

sudo systemctl disable firewalld

sudo systemctl stop firewalld

sudo systemctl disable NetworkManager

sudo systemctl stop NetworkManager

sudo systemctl enable network

sudo systemctl start network

 

3.配置/etc/hosts文件,在其中加上ip到主机名的映射

192.168.137.20 openstack-rdo

注:这一步必须得配置,否则安装过程会报错,具体报错如下面第四部分提到的第3点错误

 

三、安装

安装过程比较简单,总共就四条命令,按顺序一步步执行就可以了。

安装成功输出信息:

 **** Installation completed successfully ******

 

Additional information:

 * A new answerfile was created in: /root/packstack-answers-20180321-152621.txt

 * Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.

 * File /root/keystonerc_admin has been created on OpenStack client host 192.168.137.20. To use the command line tools you need to source the file.

 * To access the OpenStack Dashboard browse to http://192.168.137.20/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/20180321-152620-CBbu76/openstack-setup.log

 * The generated manifests are available at: /var/tmp/packstack/20180321-152620-CBbu76/manifests

注: /root/keystonerc_admin文件中有登录dashboard的用户名和密码。

 

5.在本地浏览器输入dashboard地址进行登录验证

四、可能遇到的报错(安装OpenStack时

1.ERROR:root:Failed to load plugin from file ssl_001.py

解决方法:

如上图,说是有可能没有安装python-setuptools包。于是用yum来进行安装,如下图,安装完成之后再执行sudo packstack --allinone命令继续安装OpenStack。

2.ERROR : Error appeared during Puppet run: 192.168.137.20_controller.pp

Error: Execution of ‘/usr/bin/yum -d 0 -e 0 -y install openstack-aodh-common‘ returned 1: Error downloading packages:

You will find full trace in log /var/tmp/packstack/20180321-130307-4Ja7pR/manifests/192.168.137.20_controller.pp.log

解决办法:手动安装报错的包

额...居然说目前的openstack-aodh-common已经是最新的了......

既然如此,那再次执行sudo packstack --allinone命令进行安装(再次安装没报这个错了...)

 

3.ERROR : Error appeared during Puppet run: 192.168.137.20_controller.pp

Error: /Stage[main]/Swift::Keystone::Auth/Keystone::Resource::Service_identity[swift]/Keystone_user[swift]: Could not evaluate: Command: ‘openstack ["user", "show", "--format", "shell", ["swift", "--domain", "default"]]‘ has been running for more than 40 seconds (tried 2, for a total of 170 seconds)

上图是网上查看到的解决办法(原文地址:https://www.redhat.com/archives/rdo-list/2016-July/msg00010.html),说是需更新/etc/hosts文件,在其中加上fqdn

FQDN是完全合格域名/全程域名缩写,全称为Fully Qualified Domain Name,即是域名,访问时将由DNS进行解析,得到IP。使用命令hostname -f 查看FQDN,我查到的是openstack-rdo,跟我的主机名相同,于是我在/etc/hosts文件中加上如下内容,然后再次运行

(注:本次部署在处理完这个错误之后便可以顺利地安装了,若实际安装中还有其他错误,可自行上网查找解决办法)

 

至此,部署完成。
