Packstack–answer-file deployment of multi-node OpenStack environments: four nodes

6.1 CentOS Environment Preparation

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

Modify/etc/sysconfig/network-scripts/ifcfg-eth0 in Onboot=yes

Modify/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

Configure the Yum source to be a hik internal source:

Then update the Yum Source:

# yum Clean;yumupdate; Yum Makecache

6.2 Installing Packstack

Four nodes are executed:

Yum Install Openstack-packstack-y

6.3 Installing the four-node OpenStack environment with Packstack

On the control node: first generate Answer-file:

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

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

Then modify the Hcloud.txt:

The modified points are as follows:

[[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=

Then modify the Cirros image without uploading:

config_provision_demo=y instead N

Check again before installing:

[[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

To start the installation:

# yum Install Screen-y

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