##devstack 安装openstack
devstack 主要是用于openstack 演示以及开发过程中自动化安装，通常不能直接用于生产环境部署。
###环境准备
从之前实验中准备好的虚拟机克隆一个新的虚拟机，安装CemtOS系统，配置如下
Devstack VM：
Name: devstack
vCPU:4
Memory :4G
Disk:30G
Networks: net0，net1，net2
网络环境
Net0:
Network name: VirtualBox host-only Ethernet Adapter#2
Purpose: administrator / management network
IP block: 10.20.0.210/24
DHCP: disable
Linux device: eth0
Net1:
Network name: VirtualBox host-only Ethernet Adapter#3
Purpose: public network
DHCP: disable
IP block: 172.16.0.210/24
Linux device: eth1
Net2：
Network name: VirtualBox host-only Ethernet Adapter#4
Purpose: Storage/private network
DHCP: disable
IP block: 192.168.4.210/24
Linux device: eth2
###安装步骤
devstack 的安装不能直接用root 用户，新建一个用户stack
adduser -m stack
passwd stack
从github上克隆devstack 的源码
su - stack
git clone https://github.com/openstack-dev/devstack.git
su - root
cd /home/stack/devstack/tools/create-stack-user.sh
如果你的环境需要设置代理，请添加http Proxy (可选)
export http_proxy=http://<your_proxy_ip>:<port>
export https_proxy=http://<your_proxy_ip>:<port>
排除不需要代理的IP地址(可选)
export no_proxy="127.0.0.1,192.168.1.205"
为了加速下载设置国内的pip 源，这里设置豆瓣网公开的pip源
mkdir ~/.pip
cat > ~/.pip/pip.conf <<EOF
[global]
index-url = http://pypi.douban.com/simple/
EOF
编辑local.conf 配置文件如下，只安装Keystone，Glance，Nova，Neutron
vi local.conf
[[local|localrc]]
HOST_IP=10.20.0.210
GIT_BASE=https://github.com
# Logging

ENABLED_SERVICES+=,q-svc,q-agt,q-dhcp,q-l3,q-meta,q-metering,neutron
# Neutron - Load Balancing
ENABLED_SERVICES+=,q-lbaas
运行stack.sh 安装openstack
cd /home/stack/devstack
./stack.sh
整个过程大概需要一个小时，具体时间视各地网络速度而定
最后出现类似如下输出，说明安装完成
Horizon is now available at http://10.20.0.210/
Keystone is serving at http://10.20.0.210:5000/v2.0/
Examples on using novaclient command line is in exercise.sh
The default users are: admin and demo
The password: quiet
This is your host ip: 10.20.0.210
打开浏览器输入http://10.20.0.210/ 登录Dashboard
###可能存在的问题
- 如果遇到不能连接pypi.douban.com
解决办法：还要为pypi.douban.com 添加ip 映射douban 的源 125.78.248.73，其实豆瓣也是官方给的pip源的镜像。
vi /etc/hosts
125.78.248.73 pypi.python.org
2.git heat clone 失败或者超时问题
解决办法：可以手动克隆heat 到/opt/stack 让后再运行./stack.sh
3.安装过程中检查q-dhcp 服务没有启动，安装失败。
查看/var/log/neutron/dhcp-agent.log，确认是否有以下错误出现
2013-11-15 17:18:07.785 9808 WARNING neutron.agent.linux.dhcp [-] FAILED VERSION REQUIREMENT FOR DNSMASQ. DHCP AGENT MAY NOT RUN CORRECTLY! Please ensure that its version is 2.59 or above!

解决办法：下载并安装新版本的dnsmasq，然后重新运行./stack.sh
wget http://pkgs.repoforge.org/dnsmasq/dnsmasq-2.65-1.el6.rfx.x86_64.rpm
rpm -Uvh dnsmasq-2.65-1.el6.rfx.x86_64.rpm
