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

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
-
- 安装软件包:
执行指令:
apt install chrony
-
- 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.***
-
- 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 sources210 Number of sources = 1MS 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。
