Packstack –answer-file方式部署多节点openstack环境--双节点
4.1 centos环境准备
目标：修改answer-file，将controller+network放在一个节点，compute-storage放在另一个节点，使用packstack部署双节点环境
| hostname |
IP |
Floating ip |
Function |
|
| lxp-node1 |
192.168.11.8 |
10.33.41.135 |
Controller+network |
|
| lxp-node2 |
192.168.11.9 |
10.33.41.136 |
Compute+storage |
|
在/etc/hosts中增加：
192.168.11.8 lxp-node1
192.168.11.9 lxp-node2
10.1.14.235 mirrors.hikvision.com.cn
4.2 安装packstack
yum install openstack-packstack -y
生成answer-file：
packstack --gen-answer-file=hcloud.txt
# packstack --gen-answer-file=hcloud.txt
修改hcloud.txt：
（1） 将CONFIG_PROVISION_DEMO=y改为n
（2） 修改如下IP设置：
CONFIG_CONTROLLER_HOST=192.168.11.8
CONFIG_COMPUTE_HOSTS=192.168.11.8 -> 192.168.11.9
CONFIG_NETWORK_HOSTS=192.168.11.8
CONFIG_STORAGE_HOST=192.168.11.8 -> 192.168.11.9
CONFIG_SAHARA_HOST=192.168.11.8 忽略，因为：CONFIG_SAHARA_INSTALL=n
CONFIG_AMQP_HOST=192.168.11.8
CONFIG_MARIADB_HOST=192.168.11.8
CONFIG_KEYSTONE_LDAP_URL=ldap://192.168.11.8
CONFIG_NOVA_NETWORK_FIXEDRANGE=192.168.32.0/22
CONFIG_MONGODB_HOST=192.168.11.8
CONFIG_REDIS_MASTER_HOST=192.168.11.8
其他都不用改
开始部署：
# yum install screen
# screen packstack--answer-file=hcloud.txt
这里只需要在控制节点执行

安装完毕后出现如下打印：

可以使用命令测试一下：

这里nova-compute是安装到了lxp-node2，但是cinder-volume还是在lxp-node1，看来配置还有些问题

原因是这里没有改，没有关系，后面再安装三节点的环境时注意一下
