packstack 三节点部署

 虚拟机配置

• 准备虚拟机3台，配置如下
• openstack controller
  • 2cpu，8G内存，100G硬盘
  • 配置静态IP：192.168.2.11
• nova01，nova02计算节点*2
  • 2cpu，8G内存，100G硬盘
  • 配置静态IP：192.168.2.12（13）

配置DNS

• 保证虚拟机可以访问互联网

[root@controller ~]# cat /etc/resolv.conf 
# Generated by NetworkManager
search network4
nameserver 192.168.122.254
nameserver 192.168.4.254

注意：删掉search开头的所有行 

• 保证虚拟机三节点之间可以通过主机名互访
  • /etc/hosts

时间服务

• nova服务器之间的时间必须保持一致

        centos7，使用默认配置即可。

配置yum仓库

在centos7中使用系统自带的仓库CentOS-OpenStack-rocky.repo即可

yum install -y centos-release-openstack-rocky.noarch

配置packstack 

• 安装packstack

yum install openstack-packstack -y

• 使用packstack创建通用应答文件 

packstack  --gen-answer-file=answer.ini

配置packstack 

• 修改应答文件

CONFIG_SWIFT_INSTALL=n
CONFIG_CEILOMETER_INSTALL=n
CONFIG_AODH_INSTALL=n
CONFIG_COMPUTE_HOSTS=192.168.2.12,192.168.2.14
CONFIG_NEUTRON_ML2_TYPE_DRIVERS=vxlan,flat
CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:eth0
CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=physnet1:br-ex
CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:eth0
CONFIG_PROVISION_DEMO=n

安装

packstack --answer-file=test.ini

安装输出示例

[root@controller tmp]# packstack --answer-file=test.ini
