1.设置ubuntu源
配置前，先做个配置文件的备份：
cp /etc/apt/sources.list /etc/apt/sources.list_bak
配置新的源：
nano /etc/apt/sources.list
在sources.list文件中将之前的源都注释掉，添加如下五行源：
deb http://cn.archive.ubuntu.com/ubuntu/ trusty main
restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu/ trusty-security
main restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu/ trusty-updates
main restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu/ trusty-proposed
main restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu/ trusty-backports
main restricted universe multiverse
2.更新unpdate
apt-get update
3.同步一下时间
ntpdate ntp.sjtu.edu.cn
4.安装git
apt-get install git
5.下载devstack
cd /homegit clone http://git.trystack.cn/openstack-dev/devstack.git
6.目前Devstack脚本已经不支持直接使用root身份运行，需要创建stack用户运行
cd /home/devstack/tools/./create-stack-user.sh
7.修改Devstack目标权限，让stack用户可以运行
chown -R stack:stack /home/devstackchmod 777 /dev/pts/0
8.切换到stack用户下
su stackcd /home/devstack
9.进入devstack目录下，创建local.conf文件
nano local.conf
添加如下内容
[[local|localrc]]# Define images to be automatically downloaded during the DevStack built process.DOWNLOAD_DEFAULT_IMAGES=FalseIMAGE_URLS="http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img" #change github to trystackGIT_BASE=${GIT_BASE:-http://git.trystack.cn}NOVNC_REPO=${NOVNC_REPO:-http://git.trystack.cn/kanaka/noVNC.git} # CredentialsDATABASE_PASSWORD=passADMIN_PASSWORD=passSERVICE_PASSWORD=passSERVICE_TOKEN=passRABBIT_PASSWORD=pass#FLAT_INTERFACE=eth0 HOST_IP=192.168.202.132 # Enabling Neutron (network) Servicedisable_service n-netenable_service q-svcenable_service q-agtenable_service q-dhcpenable_service q-l3enable_service q-metaenable_service q-meteringenable_service neutron ## Neutron optionsQ_USE_SECGROUP=TrueFLOATING_RANGE="192.168.202.0/24"FIXED_RANGE="10.0.0.0/24"Q_FLOATING_ALLOCATION_POOL=start=192.168.202.133,end=192.168.202.143PUBLIC_NETWORK_GATEWAY="192.168.202.2"Q_L3_ENABLED=TruePUBLIC_INTERFACE=eth0Q_USE_PROVIDERNET_FOR_PUBLIC=TrueOVS_PHYSICAL_BRIDGE=br-exPUBLIC_BRIDGE=br-exOVS_BRIDGE_MAPPINGS=public:br-ex # VLAN configuration.Q_PLUGIN=ml2ENABLE_TENANT_VLANS=True # Work offline#OFFLINE=True# Reclone each timeRECLONE=yes # Logging# -------# By default ``stack.sh`` output only goes to the terminal where it runs.

10.运行
./stack.sh
