1.环境说明

物理机操作系统：ubuntu-16.04.4-server-amd64
controller：192.168.18.61 ubuntu61
compute：192.168.18.62 ubuntu62
compute：192.168.18.63 ubuntu63

2.修改apt源

vi /etc/apt/source.list
deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse

apt-get update

3.安装 python-pip

apt-get install python-pip
检验是否安装成功：pip -V

4.下载devstack

cd /home
git clone https://git.openstack.org/openstack-dev/devstack -b stable/pike
国内源
git clone https://git.openstack.org/openstack-dev/devstack -b stable/pike

5.创建stack用户

cd /home/devstack/tools/
./create-stack-user.sh
cd /home/
mv devstack /opt/stack
chown -R stack:stack /opt/stack/devstack  
chmod 777 /dev/pts/0

6.设置pip的镜像源

分别为root和stack用户设置使用国内的pip源

mkdir ~/.pip  
vi ~/.pip/pip.conf 
[global]  
index-url = https://pypi.douban.com/simple  
download_cache = ~/.cache/pip  
[install]  
use-mirrors = true  
mirrors = http://pypi.douban.com/

su - stack  
$ mkdir ~/.pip  
$ vi ~/.pip/pip.conf 
[global]  
index-url = https://pypi.douban.com/simple  
download_cache = ~/.cache/pip  
[install]  
use-mirrors = true  
mirrors = http://pypi.douban.com/

7.编辑controller节点的local.conf

    cd /opt/stack/devstack
    vi local.conf
        [[local|localrc]]
        GIT_BASE=http://git.trystack.cn
        NOVNC_REPO=http://git.trystack.cn/kanaka/noVNC.git
        SPICE_REPO=http://git.trystack.cn/git/spice/spice-html5.git

        #初次安装设置true，重复安装设置为False
        #RECLONE=False
        RECLONE=True

        MULTI_HOST=true

        HOST_IP=192.168.18.61
        LOGFILE=/opt/stack/logs/stack.sh.log

        ADMIN_PASSWORD=123456
        MYSQL_PASSWORD=123456
        RABBIT_PASSWORD=123456
        SERVICE_PASSWORD=123456
        SERVICE_TOKEN=abcdefghijklmnopqrstuvwxyz


        disable_service n-net
        enable_service q-svc
        enable_service q-agt
        enable_service q-dhcp
        enable_service q-l3
        enable_service q-meta
        enable_service q-metering
        enable_service neutron

        Q_USE_SECGROUP=True
        FLOATING_RANGE="192.168.18.0/24"
        FIXED_RANGE="10.0.0.0/24"
        Q_FLOATING_ALLOCATION_POOL=start=192.168.18.220,end=192.168.18.230
        PUBLIC_NETWORK_GATEWAY="192.168.18.3"
        Q_L3_ENABLED=True
        PUBLIC_INTERFACE=enp7s0f0
        Q_USE_PROVIDERNET_FOR_PUBLIC=True
        OVS_PHYSICAL_BRIDGE=br-ex
        PUBLIC_BRIDGE=br-ex
        OVS_BRIDGE_MAPPINGS=public:br-ex

        Q_PLUGIN=ml2
        ENABLE_TENANT_VLANS=True

        LOG_COLOR=True
        LOGDIR=/opt/stack/logs
        SCREEN_LOGDIR=$LOGDIR/screen
            
    chown -R stack:stack /opt/stack/devstack/local.conf

8.切换到stack用户，执行安装脚本

su - stack
cd devstack/
./stack.sh

中间如果出错
./unstack.sh 后重新安装
还是出错，
./clean.sh 后重新安装

安装完成输出

9.安装compute节点

同controller节点操作一致：

更新apt源
安装 python-pip
下载devstack
创建stack用户
设置pip的镜像源

编辑local.conf

cd /opt/stack/devstack
    vi local.conf
        [[local|localrc]]

        GIT_BASE=http://git.trystack.cn
        NOVNC_REPO=http://git.trystack.cn/kanaka/noVNC.git
        SPICE_REPO=http://git.trystack.cn/git/spice/spice-html5.git

        RECLONE=False

        MULTI_HOST=true
        HOST_IP=192.168.18.62
        LOGFILE=/opt/stack/logs/stack.sh.log

        ADMIN_PASSWORD=123456
        MYSQL_PASSWORD=123456
        RABBIT_PASSWORD=123456
        SERVICE_PASSWORD=123456
        SERVICE_TOKEN=abcdefghijklmnopqrstuvwxyz

        MYSQL_HOST=$SERVICE_HOST
        RABBIT_HOST=$SERVICE_HOST
        GLANCE_HOSTPORT=$SERVICE_HOST:9292
        Q_HOST=$SERVICE_HOST
        KEYSTONE_AUTH_HOST=$SERVICE_HOST
        KEYSTONE_SERVICE_HOST=$SERVICE_HOST

        ENABLED_SERVICES=n-cpu,q-agt,neutron
        Q_PLUGIN=ml2
        ENABLE_TENANT_VLANS=True
        NEUTRON_CREATE_INITIAL_NETWORKS=False
        enable_service placement-api

        NOVA_VNC_ENABLED=True
        NOVNCPROXY_URL="http://$SERVICE_HOST:6080/vnc_auto.html"
        VNCSERVER_LISTEN=$HOST_IP
        VNCSERVER_PROXYCLIENT_ADDRESS=$VNCSERVER_LISTEN

        LOG_COLOR=True

        disable_service tempest

切换到stack用户，执行安装脚本
su - stack
cd devstack/
./stack.sh
安装完成输出
