OpenStack实践(一):Ubuntu16.04下DevStack方式搭建p版OpenStack
OpenStack实践(一):Ubuntu16.04下DevStack方式搭建p版OpenStack
OpenStack部署方式很多，常见的个人部署方式有DevStack、Rdo、all-in-one、multi-node、multi-HA-node等；企业部署方式有Ansible、SaltStack、Puppet、TripleO、Kolla、Fuel等。其中DevStack是众多开发者们的首选安装方式或工具，该方式主要是通过配置参数，执行shell脚本来安装一个OpenStack的开发环境。
OpenStack开源社区每年都会开两次设计峰会（Design Summit），发布两个正式版本。从2010年的首个版本至今，一共已经出了18个版本，每个版本都有独立名字，取自当次设计峰会所在城市中选一个地名，而且从A开始，然后B、C……。最新的版本是Rocky，字母R正好排序第18位。本文部署的版本为Pike。
本文OpenStack的控制节点和计算节点都是Esxi上新建的虚机，具体配置如下：
控制节点配置：
计算节点配置：
ubuntu安装详见：Ubuntu16.04.5以lvm方式安装全记录
控制节点和计算节点安装步骤相同，只是第6步中的配置不同，实际安装过程中应先装控制节点再装计算节点，本文以计算节点安装为例记录搭建过程。
1.pip安装
root@openstack-computer:~# pip
The program 'pip' is currently not installed. You can install it by typing:
apt install python-pip
root@openstack-computer:~# apt install -y python-pip2.代码下载
root@openstack-computer:~# git clone https://git.openstack.org/openstack-dev/devstack -b stable/pike
本文的安装版本为pike
3.创建用户stack
root@openstack-computer:~# ll
total 36
drwx------ 4 root root 4096 Nov 29 17:02 ./
drwxr-xr-x 23 root root 4096 Nov 29 16:32 ../
-rw------- 1 root root 49 Nov 29 16:47 .bash_history
-rw-r--r-- 1 root root 3106 Oct 23 2015 .bashrc
drwx------ 2 root root 4096 Nov 29 16:47 .cache/
drwxr-xr-x 17 root root 4096 Nov 29 17:02 devstack/
-rw-r--r-- 1 root root 148 Aug 17 2015 .profile
-rw------- 1 root root 3413 Nov 29 16:51 .viminfo
-rw------- 1 root root 128 Nov 29 16:47 .Xauthority
root@openstack-computer:~# devstack/tools/create-stack-user.sh

Giving stack user passwordless sudo privileges4.修改pip源
root用户修改pip源
root@openstack-computer:~# mkdir ~/.pip
root@openstack-computer:~# view ~/.pip/pip.conf
[global]
trusted-host=mirrors.aliyun.com
index-url=https://mirrors.aliyun.com/pypi/simple/stack用户修改pip源
root@openstack-computer:~# su - stack
stack@openstack-computer:~$ mkdir ~/.pip
stack@openstack-computer:~$ view ~/.pip/pip.conf
[global]
trusted-host=mirrors.aliyun.com
index-url=https://mirrors.aliyun.com/pypi/simple/5.移动devstack目录
将devstack目录由root的家目录移至/opt/stack
root@openstack-computer:~# mv devstack /opt/stack
root@openstack-computer:~# chown -R stack:stack /opt/stack/devstack6.新建配置文件

本文中参数Q_AGENT配置为linuxbridge，表示网络选择为Linux Bridge方式，如果选择Open vSwitch,则Q_AGENT=openvswitch。
7.部署openstack
stack@openstack-computer:~/devstack$ ./stack.sh控制节点安装完成：
计算节点安装完成：
8.登陆web
地址为：http://172.27.34.37，用户名密码为配置文件中的admin/admin
至此完成OpenStack安装。
9.卸载
若修改了local.conf则需先卸载再重新安装
卸载命令
stack@openstack-controller:~/devstack$ ./unstack.sh
stack@openstack-controller:~/devstack$ ./clean.sh搭建脚本已上传github：https://github.com/loong576/openstack-devstack.git
