环境介绍
安装一个控制节点[4G+40G],计算节点[2G+20G]
ubuntu16.04
网络配置
控制节点配置3块网卡(一块用作通信,一块用作neturon通信,一块用作连接外网),如下:
计算节点配置2块网卡(不需要连接外网):
先修改root密码:
1

3
4
5
6
| $ sudo su -
[sudo] password for jimo:
root@controller:~# passwd
Enter new UNIX password:
Retype new UNIX password:
passwd:
|
配置SSH
在controller查看ip:
然后在主机中通过ssh访问:
1
| $ ssh jimo@192.168.0.104
|
允许root用户SSH访问:
编辑配置文件: /etc/ssh/sshd_config:
记得重启ssh服务
配置IP
其中一块配置静态IP,其他交给openstack.
编辑 /etc/network/interfaces:

dns-nameservers 192.168.0.1
auto enp0s8
iface enp0s8 inet manual
auto enp0s9

同样将计算节点也配置成这样,IP为20.

现在相互间应该可以ping通,控制节点可以访问网络.
安装openstack
我们使用devstack
保证有pip和git
1
2
| $ sudo apt install python-pip
$ sudo apt install git
|
创建stack用户并获取devstack:

| jimo@controller:~$ sudo useradd -s /bin/bash -d /opt/stack -m stack
[sudo] password for jimo:
jimo@controller:~$ echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack
stack ALL=(ALL) NOPASSWD: ALL
jimo@controller:~$ sudo su - stack
stack@controller:~$ pwd
/opt/stack
stack@controller:~$ ls
examples.desktop
stack@controller:~$ git clone https://git.openstack.org/openstack-dev/devstack

stack@controller:~$ cd devstack/
stack@controller:~/devstack$

同时更换root和stack用户的pip源,切换到stack用户并更换pip源为豆瓣的:

| $ su - stack
root@controller:~# su - stack
stack@controller:~$ mkdir .pip
stack@controller:~$ cd .pip/
stack@controller:~/.pip$ vim pip.conf
stack@controller:~/.pip$ cat pip.conf
[global]
index-url =https://pypi.douban.com/simple/
download_cache = ~/.cache/pip
[install]
use-mirrors =true
mirrors =http://pypi.douban.com/simple/
trusted-host =pypi.douban.com
|
接着在devstack目录下创建local.conf文件,内容如下:

然后就可以执行stack.sh了.

在虚拟机中不要关闭,休眠即可,因为下次还得重新执行stack.sh
