虚拟机ubuntu-20.04.6-live-server搭建OpenStack:Victoria(二:OpenStack环境准备-compute node)


Host networking

a. 配置网络接口

  • 切换至超级用户模式:

执行指令:

sudo su
  • 将第二个接口配置为 provider interface:

执行指令:

vim /etc/network/interfaces

添加或修改为以下内容:

# The provider network interface
auto INTERFACE_NAME
iface  INTERFACE_NAME inet manual
up ip link set dev $IFACE up
down ip link set dev $IFACE down

提示:用实际接口名称替换 INTERFACE_NAME。即:ens34

  • 配置主机名解析:

执行指令:

vim /etc/hosts

添加或修改为以下内容:

127.0.0.1           localhost
192.168.10.10       controller
192.168.10.20       compute

b. 验证连通性

执行指令:

ping -c 4 openstack.org
ping -c 4 controller

输出示例:

# ping -c 4 openstack.org
PING openstack.org (174.143.194.225) 56(84) bytes of data.

Network Time Protocol (NTP)

安装 Chrony以在节点间正确同步服务。

a. 安装并配置组件

    1. 安装软件包:

执行指令:

apt install chrony
    1. 修改 chrony.conf 的配置为引用 controller node

执行指令:

vim /etc/chrony/chrony.conf

添加以下内容:

server controller iburst

注释掉以下内容:

pool 2.debian.pool.ntp.org offline iburst

提示:
pool 2.debian.pool.ntp.org offline iburst修改为# pool 2.debian.pool.ntp.org offline iburst
可能内容不全一样, pool 2.debian.pool.***

    1. 重启 NTP 服务

执行指令:

service chrony restart

b. 验证操作

执行指令:

chronyc sources

输出示例:

# chronyc sources
  210 Number of sources = 1
  MS Name/IP address         Stratum Poll Reach LastRx Last sample
  ===============================================================================
  ^* controller                    3    9   377   421    +15us[  -87us] +/-   15ms

OpenStack packages

a. 下载Victoria云存储仓库

执行指令:

add-apt-repository cloud-archive:victoria

b. 安装示例

执行指令:

apt install nova-compute

c. 安装客户端

执行指令:

apt install python3-openstackclient

下面的内容跟上面的是一样的,但少了说明,更专注于有用内容的执行。


沉浸版指令及内容:

指令:

sudo su
