使用DevStack安装openstack（单机环境）

eddik

　　DevStack是一系列可扩展的脚本，用于根据git master的最新版本快速启动完整的OpenStack环境。它以交互方式用作开发环境，并作为OpenStack项目功能测试的基础。

　　参考源码。

　　警告：DevStack will make substantial changes to your system during installation. Only run DevStack on servers or virtual machines that are dedicated to this purpose.

一、支持环境

支持系统	支持版本
Ubuntu	16.04/17.04
Fedora	24/25
CentOS/RHEL	7
Debian
OpenSUSE

　　官方建议Ubuntu 16.04系统。

二、安装准备
　　Devstack应该作为一个非root用户运行，并且启用sudo权限。。
　　1. 添加stack用户



$ sudo useradd -s /bin/bash -d /opt/stack -m stack
　　2. 更改用户权限
　　由于此用户将对系统进行许多更改，因此应具有sudo权限：



$ echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack
$ sudo su - stack
三、下载安装DevStack
　　1. 下载安装仓库
　　devstack 仓库包含一个安装OpenStack的脚本和配置文件的模板



$ git clone https://git.openstack.org/openstack-dev/devstack
$ cd devstack

　　2. 新建/修改配置文件
　　创建配置文件local.conf并写入4个密码预设：



[[local|localrc]]
ADMIN_PASSWORD=secret
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD

　　这是开始使用DevStack所需的最低配置。
　　3. 开始安装



./stack.sh
　　这将需要15 - 20分钟，主要取决于您的互联网连接的速度。在此过程中将安装许多仓库树和包。单机（2核4G）实际测试安装近两个小时，所以大家可以启动后台进程安装：



nohup ./stack.sh &
　　查看安装日志位置：



/opt/stack/logs
　　后台进程安装时，查看安装shell输出记录：



/opt/stack/devstack/nohup.out
四、说明
　　1. DevStack将会安装 keystone, glance, nova, cinder, neutron和horizon组件；当然，浮动IP也可以使用。
　　2. 您可以访问horizon以体验OpenStack的Web界面，并从中管理vms，网络，卷和图像。
　　3. 您可以在shell中输入以下命令 ，然后使用openstack命令行工具来管理您的devstack



source openrc
　　4. 您可以进入以下目录， 然后运行临时测试。



cd /opt/stack/tempest
　　5. 您可以检查DevStack服务的状态



# 大部分devStack服务运行在系统的名称为：devstack@$servicename.service，您可以使用以下方法
sudo systemctl status "devstack@*"


[stack@10-9-157-7 devstack]$ sudo systemctl status "devstack@*"

　　6. 如果更改了组件配置，可以使用以下命令使之生效：



# 例如更改了 /opt/stack/$service 代码后（假设服务名称为n-cpu），使用
sudo systemctl restart devstack@n-cpu.service


# 如果您的更改影响多个守护程序，您可以通过通配符重新启动。
sudo systemctl restart "devstack@n-*"
