packstack –answer-file方式部署多节点openstack环境：四节点
6.1 CentOS环境准备
| Vm name |
Hostname |
IP |
Function |
| Lxp-centos-1 |
hcloud.controller |
192.168.11.13/10.33.41.132 |
Controller |
| Lxp-centos-2 |
hcloud.network |
192.168.11.14/10.33.41.135 |
Network |
| Lxp-centos-3 |
hcloud.compute1 |
192.168.11.15/10.33.41.139 |
Compute1 |
| Lxp-centos-4 |
hcloud.compute2 |
192.168.11.16/10.33.41.148 |
Compute2 |
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：
[root@hcloudetc]# 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：
[root@hcloud 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：
[root@hcloud 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
[root@hcloud 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
