最近在做openstack与Docker的集成工作，走了不少弯路，遇到不少问题，不过最终搭建成功了。现在将过程分享出来，以供参考。
一、环境介绍
1、软件环境：
CentOs7 64位、OpenStack（Juno）、Docker version 1.5.0
2、网络：
$vim /etc/hosts 192.168.245.148 compute1 192.168.245.141 controller
3、安装前提：
3.1 控制节点安装
身份认证服务——Keystone
镜像服务——Glance
计算服务——Nova
网络服务——Nova-network
Web界面——Dashboard
3.2 计算节点安装：
计算服务——Nova
网络服务——Nova-network
3.3 计算节点与控制节点已联通
二、计算节点配置
1、管理员权限：
$su
2、关闭防火墙、selinux
$systemctl stop firewalld.service $setenforce
3、安装Docker
$yum install docker
4、获得Docker CentOs镜像、开启容器
$docker pull centos $docker images centos $docker run -i -t centos /bin/bash $exit
5、nova-docker-driver安装前准备工作
5.1 安装pip
官网下载安装包 https://pypi.python.org/pypi/pip 。解压之后：
$python setup.py install
5.2 安装Python-dev
$yum install python-devel
6、nova-docker-driver安装
$pip install -e git+https://github.com/stackforge/nova-docker#egg=novadocker $cd src/novadocker/ $python setup.py install
7、Nova配置
配置 /etc/nova/nova.conf
$vim /etc/nova/nova.conf [DEFAULT] compute_driver = novadocker.virt.docker.DockerDriver
创建文件夹 /etc/nova/rootwrap.d在其中创建文件docker.filters，内容如下：
# nova-rootwrap command filters for setting up network in the docker driver # This file should be owned by (and only-writeable by) the root user [Filters] # nova/virt/docker/driver.py: 'ln', '-sf', '/var/run/netns/.*' ln: CommandFilter, /bin/ln, root
三、控制节点配置
$vim /etc/glance/glance-api.conf container_formats=ami,ari,aki,bare,ovf,ova,docker
四、docker镜像发布
$vim admin.sh export OS_TENANT_NAME=admin export OS_USERNAME=admin export OS_PASSWORD=YOUR_PASS export OS_AUTH_URL=http://controller:35357/v2.0
$source admin.sh $docker save centos | glance image-create --is-public=True --container-format=docker --disk-format=raw --name centos
至此，基本的安装配置已完成，你可以尝试在控制节点的web界面上启动centOS的镜像实例。
但事实远非如此，以下记录排错过程。涉及到的日志文件有
控制节点上：/var/log/nova/nova-scheduler.log、/var/log/nova/nova-conductor.log
计算节点上：/var/log/nova/nova-compute.log、/var/log/messages、systemctl status openstack-nova-network.service –l 、systemctl status openstack-nova-compute.service -l

This looks like that the owner of the nova-compute process does not have write permission to the docker socket:

$vim /etc/selinux/config
2 SELINUX=disabled
重启机器即可
