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

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 SERVICE_HOST=192.168.18.61 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

最后，要让计算节点注册在控制节点上运行
root@ubuntu61:/opt/stack/devstack/tools# ./discover_hosts.sh
