centos6.5上使用devstack部署openstack开发环境

shenzhang

　　一、环境准备
　　1、操作系统配置
　　关闭selinux，并重启系统。
　　[root@localhost ~]# cat /etc/sysconfig/selinux
SELINUX=disabled
　　2、安装所需的包
　　[root@localhost ~]# yum -y install vim git python-setuptools
　　yum安装的pip包版本不对，安装时会出错，从网上下载pip源码包，源码安装pip包
　　pip源我们采用系统默认的源就好，安装pip源码
　　[root@localhost ~]# tar xvzf pip-6.0.8.tar.gz
　　[root@localhost ~]# cd pip-6.0.8
　　[root@localhost pip-6.0.8]# python setup.py install
　　有一个rpm包，yum源里面没有，需要下载下来手工安装，否则安装时会报错，命令如下：
　　rpm -ivh python-mox-0.5.3-1.3.x86_64.rpm
　　二、获取源码
　　[root@localhost pip-6.0.8]# cd /home/
[root@localhost home]# git clone -b stable/icehouse  https://github.com/openstack-dev/devstack.git

　　创建stack用户
　　[root@localhost home]# cd devstack/tools/
[root@localhost tools]# ./create-stack-user.sh
Creating a group called stack
Creating a user called stack
Giving stack user passwordless sudo privileges
　　为home/devstack目录赋给stack用户可执行权限
　　[root@localhost tools]# chown -R stack:stack /home/devstack/
　　三、开始安装

　　[root@localhost ~]# su stack
[stack@localhost root]$ cd /home/devstack/
　　编辑本目录下的localrc文件，然后执行安装

　　[stack@localhost devstack]$ ./stack.sh
　　我的localrc文件如下：
　　HOST_IP=*.*.*.*
DATABASE_PASSWORD=123456
ADMIN_PASSWORD=123456
SERVICE_PASSWORD=123456
SERVICE_TOKEN=123456
RABBIT_PASSWORD=123456

　　安装过程中有如下报错：
　　Loaded plugins: fastestmirror, refresh-packagekit
Using mysql database backend
Traceback (most recent call last):
  File "/home/devstack/tools/outfilter.py", line 24, in <module>
    import argparse
ImportError: No module named argparse
[stack@localhost devstack]$ sudo pip install argparse
You are using pip version 6.0.8, however version 7.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Collecting argparse
  Downloading argparse-1.3.0-py2.py3-none-any.whl
Installing collected packages: argparse

Successfully installed argparse-1.3.0
　　根据错误提示需要将pip升级到7.0.1版本,升级后重新执行安装脚本
[stack@localhost devstack]$ sudo pip install --upgrade pip
　　[stack@localhost devstack]$ ./stack.sh

　　安装过程中可能会遇到各种问题，根据报错信息，一一解决即可

　　出现下面提示，表示安装完成
　　

　　Horizon is now available at http://*.*.*.*/
Keystone is serving at http://*.*.*.*:5000/v2.0/
Examples on using novaclient command line is in exercise.sh
The default users are: admin and demo
The password: 123456
This is your host ip: *.*.*.*
　　然后可以通过horizon登陆系统。
