Packstack–answer-file deployment of multi-node OpenStack environments-two-node

4.1 CentOS Environment Preparation

Goal: Modify Answer-file, place controller+network on one node, compute-storage on another node, deploy a two-node environment using Packstack

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

Added in/etc/hosts:

192.168.11.8 Lxp-node1

192.168.11.9 Lxp-node2

10.1.14.235 mirrors.hikvision.com.cn

4.2 Installing Packstack

Yum Install Openstack-packstack-y

Generate Answer-file:

Packstack--gen-answer-file=hcloud.txt

# Packstack--gen-answer-file=hcloud.txt

Modify Hcloud.txt:

(1) Change config_provision_demo=y to N

(2) Modify the following IP settings:

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 ignored because: 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

Don't change anything else.

Start deployment:

# Yum Install screen

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

This only needs to be performed at the control node

here Nova-compute is installed in the Lxp-node2 , but Cinder-volume is still in Lxp-node1 , it seems there are some problems with the configuration

The reason is that there is no change, no relationship, after the installation of the three-node environment, pay attention to
