再玩 DevStack（Mitaka版）- 基于 trystack.cn 源

曾经就写过一篇关于DevStack安装OpenStack的文章《使用 DevStack 高速部署 OpenStack 开发环境》，时过境迁，如今有更好的方式来实现。想到曾经的复杂性，认为有必要更新一下。免得误人子弟。

首先必须感谢陈沙克老师，他们自己做了git.trystack.cn源，提供OpenStack的全部github的mirror，直接是国内玩DevStack的福利啊！听说他在准备Fuel的国内源，相当敬佩，这才是真正为技术发展做贡献的。

前言

这次是基于国内的trystack.cn源安装，简单易用。

沙克老师已经写过两篇相关博文，此文仅是做一个记录。

1、环境准备

1.1 网络设置

使用VMware Workstation安装，网络连接使用NAT模式，dhcp获得IP地址192.168.27.128/24。NAT的网关是192.168.27.2。

1.2 安装系统

查看IP地址，编辑SSH同意root用户远程登录。

root@devstack:~# ifconfig

eth0 Link encap:Ethernet HWaddr 00:0c:29:08:52:99

inet addr:192.168.27.128 Bcast:192.168.27.255 Mask:255.255.255.0

inet6 addr: fe80::20c:29ff:fe08:5299/64 Scope:Link

UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX packets:70 errors:0 dropped:0 overruns:0 frame:0

TX packets:68 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:1000

RX bytes:9022 (9.0 KB) TX bytes:10704 (10.7 KB)

root@devstack:~# vi /etc/ssh/sshd_config

PermitRootLogin yes

1.3 设置Ubuntu的源

把Ubuntu的源改成国内的，速度要快非常多。我习惯用阿里。

deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

1.4 更新系统

1	`apt-get update && apt-get dist-upgrade -y`

2、開始安装

2.1 安装git

1	`apt-get` `install` `git`

2.2 下载DevStack

1 2	`cd` `/home` `git clone http://git.trystack.cn/openstack-dev/devstack.git`

2.3 创建stack用户

1 2	`cd` `/home/devstack/tools/` `./create-stack-user.sh`

2.4 改动DevStack文件夹权限。让stack用户能够执行

1 2	`chown` `-R stack:stack` `/home/devstack` `chmod` `777` `/dev/pts/0`

2.5 切换到stack用户

1 2	`su` `stack` `cd` `/home/devstack`

2.6 编辑local.conf

[[local|localrc]]
