安装Openstack

news 2025/6/9 7:17:52

基本按照Ubuntu官网的指南来安装，使用单节点模式，官网步骤参见网址：https://ubuntu.com/openstack/install

系统为Ubuntu 24.04.2，全新安装.

Welcome to Ubuntu 24.04.2 LTS (GNU/Linux 6.11.0-24-generic x86_64)kai@experiment:~$ sudo snap install openstack --channel 2024.1/candidate 
openstack (2024.1/candidate) 2024.1 from Canonical✓ installed

运行依赖安装脚本，并且将当前用户的sudo设置为无密码(NOPASSWD:ALL)：

kai@experiment:~$ sunbeam prepare-node-script --bootstrap | bash -x && newgrp snap_daemon
++ lsb_release -sc
...
Bootstrap agent now started
Contacting Juju controller at 10.161.243.43 to verify accessibility...Bootstrap complete, controller "localhost-localhost" is now available
Controller machines are in the "controller" modelNow you can runjuju add-model <model-name>
to create a new model to deploy workloads.
+ echo 'Juju bootstrap complete, you can now bootstrap sunbeam!'
Juju bootstrap complete, you can now bootstrap sunbeam!

在部署openstack之前，设置代理，ubuntu官网的步骤中没有此步骤。192.168.5.191是局域网中的一个代理软件，注意NO_PROXY的配置，本机回环地址和私有地址不需要代理。

kai@experiment:~/work$ cat /etc/environment
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin"
HTTP_PROXY=http://192.168.5.191:7890
HTTPS_PROXY=http://192.168.5.191:7890
NO_PROXY=localhost,experiment,127.0.0.1,10.161.243.43,10.0.0.0/8,172.16.0.0/12,192.168.0.0/16

使用cluster bootstrap部署openstack，并且接收默认的软件。

kai@experiment:~$ sunbeam cluster bootstrap --accept-defaults
Node has been bootstrapped with roles: control, compute

查看创建的cluster信息。

kai@experiment:~$ sunbeam cluster listopenstack-machines                   
┏━━━━━━━━━━━━━━┳━━━━━━━━━┳━━━━━━━━━┳━━━━━━━━━┳━━━━━━━━━┓
┃ Node         ┃ Machine ┃ Compute ┃ Control ┃ Storage ┃
┡━━━━━━━━━━━━━━╇━━━━━━━━━╇━━━━━━━━━╇━━━━━━━━━╇━━━━━━━━━┩
│ 10.161.243.1 │ running │ active  │ active  │         │
└──────────────┴─────────┴─────────┴─────────┴─────────┘

配置openstack，并且创建demo用户。

kai@experiment:~$ sunbeam configure --accept-defaults --openrc demo-openrc
⠸ Generating openrc for cloud admin usage ... Writing openrc to demo-openrc ... done
The cloud has been configured for sample usage.
You can start using the OpenStack client or access the OpenStack dashboard at http://172.16.1.205:80/openstack-horizon

生成demo-openrc文件在当前目录下，包括demo用户和密码登，内容如下：

kai@experiment:~$ cat demo-openrc 
# openrc for demo
export OS_AUTH_URL=http://172.16.1.205/openstack-keystone/v3
export OS_USERNAME=demo
export OS_PASSWORD=SFMcoRPeolQL
export OS_USER_DOMAIN_NAME=users
export OS_PROJECT_DOMAIN_NAME=users
export OS_PROJECT_NAME=demo
export OS_AUTH_VERSION=3
export OS_IDENTITY_API_VERSION=3

安装之后，自带一个ubuntu 22.04 LTS的镜像，如下：

kai@experiment:~$ openstack image list 
+--------------------------------------+--------+--------+
| ID                                   | Name   | Status |
+--------------------------------------+--------+--------+
| a48cfdb9-1b61-4fcd-94ad-6b1a466102d9 | ubuntu | active |
+--------------------------------------+--------+--------+

使用此镜像创建实例test：

kai@experiment:~$ sunbeam launch ubuntu --name test
Launching an OpenStack instance ... 
Access the instance by running the following command:
`ssh -i /home/kai/snap/openstack/712/sunbeam ubuntu@172.16.2.81`

实例创建需要等待一会，1,2分钟左右，时长和机器配置相关。使用ssh可以登录。

kai@experiment:~$ ssh -i /home/kai/snap/openstack/712/sunbeam ubuntu@172.16.2.81
The authenticity of host '172.16.2.81 (172.16.2.81)' can't be established.
ED25519 key fingerprint is SHA256:oZ9wg4nS/JFil9zI0lGM45NVU5KWn58Mt4qFllCf67o.
This key is not known by any other names.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

openstack cli

在命令行使用CLI，需要admin账户，如下创建管理账户。

kai@experiment:~$ sunbeam openrc > admin-openrc

管理账户信息如下。

kai@experiment:~$ cat admin-openrc 
# openrc for access to OpenStack
export OS_USERNAME=admin
export OS_PASSWORD=7FP1eYYRsWah
export OS_AUTH_URL=http://172.16.1.205/openstack-keystone/v3
export OS_USER_DOMAIN_NAME=admin_domain
export OS_PROJECT_DOMAIN_NAME=admin_domain
export OS_PROJECT_NAME=admin
export OS_AUTH_VERSION=3
export OS_IDENTITY_API_VERSION=3

使用source命令，当前shell环境下就可以使用openstack命令了。

kai@experiment:~$ source admin-openrc

如下查看flavor和network信息：

kai@experiment:~$ openstack flavor list
