packstack –answer-file方式部署多节点openstack环境：四节点

6.1 CentOS环境准备

修改/etc/sysconfig/network-scripts/ifcfg-eth0中ONBOOT=yes

修改/etc/hostname、/etc/hosts：

192.168.11.13hcloud.controller

192.168.11.14hcloud.network

192.168.11.15hcloud.compute1

192.168.11.16hcloud.compute2

10.1.14.235  mirrors.hikvision.com.cn

配置yum源为hik内部源：

然后更新yum源：

# yum clean;yumupdate; yum makecache

6.2 安装packstack

四个节点都执行一下：

yum install openstack-packstack -y

6.3 使用packstack安装四节点openstack环境

在控制节点：首先生成answer-file：

[[email protected]]#   packstack--gen-answer-file=hcloud.txt

Packstack changedgiven value  to required value/root/.ssh/id_rsa.pub

然后修改hcloud.txt：

修改点如下：

[[email protected] etc]#grep HOST ./hcloud.txt

CONFIG_CONTROLLER_HOST=192.168.11.13

CONFIG_COMPUTE_HOSTS=192.168.11.13 -> CONFIG_COMPUTE_HOSTS=192.168.11.15,192.168.11.16

CONFIG_NETWORK_HOSTS=192.168.11.13-> CONFIG_NETWORK_HOSTS=192.168.11.14

CONFIG_VCENTER_HOST=

CONFIG_STORAGE_HOST=192.168.11.13-> CONFIG_STORAGE_HOST=192.168.11.15,192.168.11.16

CONFIG_SAHARA_HOST=192.168.11.13

CONFIG_AMQP_HOST=192.168.11.13

CONFIG_MARIADB_HOST=192.168.11.13

CONFIG_CINDER_NETAPP_HOSTNAME=

然后修改不上传cirros镜像：

CONFIG_PROVISION_DEMO=y改为n

安装前再检查一下：

[[email protected] etc]#grep HOST ./hcloud.txt

CONFIG_CONTROLLER_HOST=192.168.11.13

CONFIG_COMPUTE_HOSTS=192.168.11.15,192.168.11.16

CONFIG_NETWORK_HOSTS=192.168.11.14

CONFIG_VCENTER_HOST=

CONFIG_STORAGE_HOST=192.168.11.15,192.168.11.16

[[email protected] etc]#grep PROV ./hcloud.txt

CONFIG_PROVISION_DEMO=n

CONFIG_PROVISION_TEMPEST=n

开始安装：

# yum install screen -y

# screen packstack--answer-file=hcloud.txt

Welcome to thePackstack setup utility
