控制节点和计算节点都执行:

安装好ubuntu1~22.04 并确认系统版本

cat /proc/version

Linux version 5.15.0-60-generic (buildd@lcy02-amd64-054) (gcc (Ubuntu 11.3.0-1ubuntu1~22.04) 11.3.0, GNU ld (GNU Binutils for Ubuntu) 2.38) #66-Ubuntu SMP Fri Jan 20 14:29:49 UTC 2023

分别修改

控制节点
ip 10.0.0.11
主机名 controller

和计算节点
ip 10.0.0.31
主机名 compute1

的主机名、ip

修改ip:
vim /etc/netplan/00-installer-config.yaml

# This is the network config written by 'subiquity'
network:
ethernets:
eno1:
dhcp4: true
enp38s0:
addresses: [10.0.0.31/24]
nameservers:
addresses: [114.114.114.114, 8.8.8.8]
version: 2

修改主机名:

hostname controller

echo "controller">/etc/hostname

将第二个接口配置为提供程序 接口 替换为实际接口名称。例如,eth1 或 ens224。INTERFACE_NAME

vim /etc/network/interfaces

# The provider network interface
auto enp38s0
iface enp38s0 inet manual
up ip link set dev $IFACE up
down ip link set dev $IFACE down

修改hosts

vim /etc/hosts


127.0.0.1 controller
# controller
10.0.0.11 controller
# compute1
10.0.0.31 compute1
# block1
10.0.0.41 block1
# object1
10.0.0.51 object1
# object2
10.0.0.52 object2

块存储节点(可选)

块存储节点(可选)— 安装指南文档 (openstack.org)

验证连接性

验证连接 — 安装指南文档 (openstack.org)

网络时间协议 (NTP)

控制节点:

apt install chrony
vim /etc/chrony/chrony.conf
allow 10.0.0.0/24
service chrony restart

计算节点:

apt install chrony
vim /etc/chrony/chrony.conf

pool controller iburst maxsources 4
#pool ntp.ubuntu.com iburst maxsources 4
#pool 0.ubuntu.pool.ntp.org iburst maxsources 1
#pool 1.ubuntu.pool.ntp.org iburst maxsources 1
#pool 2.ubuntu.pool.ntp.org iburst maxsources 2


service chrony restart

验证操作:

chronyc sources

所有节点上关闭自动更新:

vim /etc/apt/apt.conf.d/20auto-upgrades

将内容中所有值为 1 的都改成 0 后保存退出, 编辑文件需要sudo权限


APT::Periodic::Update-Package-Lists "0";
APT::Periodic::Unattended-Upgrade "0";

所有节点执行:


add-apt-repository cloud-archive:zed


apt install nova-compute


apt install python3-openstackclient
