一直想学习下openstakc的源代码，期间用packstack安装成功过，但是devstack一直安装失败，终于在试验了很多次之后，终于成功了！踩坑无数。。。

环境准备：

centos7.3.1611最小化安装（16G内存、60G硬盘、因为直接在服务器上开虚拟机测试的，内存调到比较大，目测4G以上应该都没问题） devstack版本：newton openstack版本：newton

安装过程

一、准备工作 1.selinux、firewalld关闭

systemctl stop firewalld.service #停止firewallsystemctl disable firewalld.service #禁止firewall开机启动

2.使用豆瓣pip源

mkdir -p ~/.pipvi ~/.pip/pip.conf[global]index-url = http://pypi.douban.com/simple/[install]trusted-host = pypi.douban.com

3.下载并安装EPEL

wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpmrpm -ivh epel-release-latest-7.noarch.rpmyum repolist      ##检查是否已添加至源列表

4.安装工具包

yum install -y Python-pippip install --upgrade pippip install -U os-testr yum -y install bridge-utils  yum -y install net-tools  yum install -y git yum-utils

5.更新系统

yum update

二、开始安装

1.下载devstack

git clone https://github.com/openstack-dev/devstack.git -b stable/newton

此处有大坑！注意一定要使用 -b stable/newton 指定devstack版本（与要安装的openstack版本一致），否则基本上不会安装成功！

ps:我一开始下载devstack的时候，没有使用该选项，导致安装到keystone时，调用了未知的参数，一直失败。 2.创建stack用户，并切换至stack用户（devstack默认必须使用stack用户安装）

cd /home/devstack/tools/./create-stack-user.shchown -R stack:stack /home/devstackchmod 777 /opt/stack -Rsu stack

3.创建local.conf文件，这里参考了陈沙克老师博客中的配置。

[[local|localrc]]DEST=/opt/stack/newton# use TryStack git mirrorGIT_BASE=http://git.trystack.cnNOVNC_REPO=http://git.trystack.cn/kanaka/noVNC.gitSPICE_REPO=http://git.trystack.cn/git/spice/spice-html5.git#OFFLINE=True#RECLONE=TrueRECLONE=no# Define images to be automatically downloaded during the DevStack built process.DOWNLOAD_DEFAULT_IMAGES=FalseIMAGE_URLS="http://images.trystack.cn/cirros/cirros-0.3.4-x86_64-disk.img"HOST_IP=192.168.129.120# CredentialsDATABASE_PASSWORD=yourpassADMIN_PASSWORD=yourpassSERVICE_PASSWORD=yourpassSERVICE_TOKEN=yourpassRABBIT_PASSWORD=yourpassHORIZON_BRANCH=stable/newtonKEYSTONE_BRANCH=stable/newtonNOVA_BRANCH=stable/newtonNEUTRON_BRANCH=stable/newtonGLANCE_BRANCH=stable/newtonCINDER_BRANCH=stable/newton#keystoneKEYSTONE_TOKEN_FORMAT=UUID##HeatHEAT_BRANCH=stable/newtonenable_service h-eng h-api h-api-cfn h-api-cw## SwiftSWIFT_BRANCH=stable/newtonENABLED_SERVICES+=,s-proxy,s-object,s-container,s-accountSWIFT_REPLICAS=1SWIFT_HASH=011688b44136573e209e# 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="192.168.129.0/24"FIXED_RANGE="10.0.0.0/24"Q_FLOATING_ALLOCATION_POOL=start=192.168.129.200,end=192.168.129.249PUBLIC_NETWORK_GATEWAY="192.168.129.1"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# LoggingLOGFILE=/opt/stack/logs/stack.sh.logVERBOSE=TrueLOG_COLOR=TrueSCREEN_LOGDIR=/opt/stack/logs

需要替换的内容是

1)换成你自己的ip地址

HOST_IP=192.168.129.120

2)换成你自己ip地址的网段。

##你ip地址的网段FLOATING_RANGE="192.168.129.0/24" ##该网段内的一个ip池，自己定一个开始地址和结束地址Q_FLOATING_ALLOCATION_POOL=start=192.168.129.200,end=192.168.129.249##你ip地址的网关PUBLIC_NETWORK_GATEWAY="192.168.129.1"

需要注意的是：

配置文件中需指定，你要安装的openstack版本，并且与你的devstack版本一致。

HORIZON_BRANCH=stable/newtonKEYSTONE_BRANCH=stable/newtonNOVA_BRANCH=stable/newtonNEUTRON_BRANCH=stable/newtonGLANCE_BRANCH=stable/newtonCINDER_BRANCH=stable/newton

4.开始安装

./stack

5.安装成功后，如果打不开dashboard，记得关闭下防火墙。

service iptables stop

6.查看安装记录

三、踩坑记录

1.一定注意devstack和openstack版本一致！！！

一定注意devstack和openstack版本一致！！！ 一定注意devstack和openstack版本一致！！！ 2.如果发生eception

./unstack./stack

3.git clone源代码时，如果连续好长时间卡住不动，应该时网速的问题。

好像默认git clone不能断点续传，所以一定要挑个网速好的时候进行。 4.其他包依赖关系，百度谷歌一下，基本上都能解决。

四、总结

其实devstack安装并不难，只要local.conf配置好，版本选对，网速好，多运行几次都能安装成功！奉上安装成功的图片，希望大家安装的一帆风顺！ 最后欢迎大家私聊，互相学习，互相进步！
