控制节点

Hostname: controller

OS: ubuntu 16.04 server

Mem: 8g

Disk: 100g

网络1: 192.168.104.10

网络2: manual

网络3: 10.0.0.110 (请根据自己的情况做修改)

计算节点

Hostname: compute

OS: ubuntu 16.04 server

Mem: 8G

Disk: 50G

网络1: 192.168.104.11

网络2: manual

网络3: 10.0.0.111 (非必须，只是个人为了ssh方便)

网络环境说明

网络1用于openstack的管理

网络2用于租户网络

网络3用于连接外网

安装ubuntu 16.04时选择Virtual Machine host和OpenSSH Server

设置ubuntu使用root用户

使用安装时创建的用户ssh到服务器，比如用户名是chenhf，那么ssh chenhf@10.0.0.110

sudo su -

passwd

vim /etc/ssh/ssh_config

PermitRootLogin yes

systemctl restart sshd

配置网络/etc/network/interfaces

设置ubuntu apt源国内镜像

安装pip

apt install python-pip

设置python pip源国内镜像

mkdir .pip

vim .pip/pip.conf

[global]
index-url = https://pypi.douban.com/simple
download_cache = ~/.cache/pip
[install]
use-mirrors = true
mirrors = http://pypi.douban.com/

ubuntu apt源和python pip源也可以使用阿里云、网易、清华大学的源。

安装Stack

git clone https://git.openstack.org/openstack-dev/devstack -b stable/ocata

创建用户stack

devstack/tools/create-stack-user.sh

mv devstack /opt/stack/

chown -R stack:stack /opt/stack/devstack

切换到用户stack

su - stack

设置pip国内镜像

mkdir .pip

vim .pip/pip.conf

[global]
index-url = https://pypi.douban.com/simple
download_cache = ~/.cache/pip
[install]
use-mirrors = true
mirrors = http://pypi.douban.com/

安装过程中常见问题

报错No matching distribution found for oslo.messaging===5.17.3 ，查看日志发现是在/opt/stack/requirements/upper-constraints.txt文件的第243行，版本要求为5.17.3，但实际上不存在这个版本，修改版本为5.17.2后就可以成功安装了。
