OpenStack简介

OpenStack：是一个开源软件，它提供了开放源码，可以建立公有和私有云，目的在于帮助组织运行虚拟计算或服务存储的云。

一般分为四个节点
控制节点：对其余节点的控制，包括虚拟机建立，迁移，网络分配等
计算节点：负责虚拟机的运行
网络节点：负责对外网络与内网络之间的通信
存储节点：负责对虚拟机的额外存储管理

核心组件及可选组件如下：

OpenStack单节点搭 openstack单节点安装_OpenStack单节点搭

控制节点包括以下服务：

管理支持服务：
MySQL：存储其他服务的基本信息以及产生的数据
Qpid：消息代理(也称消息中间件)为其他各种服务之间提供了统一的消息通信服务（RabbitMQ）

管理基础服务：
keystone：认证管理服务，提供了其余所有组件的认证信息/令牌的管理、创建、修改等。
Glance：镜像管理服务，提供了对虚拟机部署的时候所能提供的镜像的管理，包含镜像的导入，格式以及制作的模板。
Nova：计算管理服务，提供了对计算节点的Nova的管理，使用Nova-api进行通信
Neutron：网络管理服务，提供了对网络节点的网络拓扑管理
Horizon：控制台服务，以web形式对所有节点的所有服务的管理，一般称为dashboard

扩展管理服务：Cinder，Swift，Trove，Heat，Centimeter五个服务

准备工作

两台机器
操作系统为centos7
安装好并且配置固定ip
修改主机名为test-1,test-2
设test-1位控制节点，test-2位计算节点
然后vi /etc/hosts 加入如下内容：

59.64.78.64		test-1
59.64.78.65		test-2

之后需要能互相ping通且能通ping外网

关闭selinux

sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/sysconfig/selinux
setenforce 0

关闭防火墙

systemctl stop firewalld.service

安装NTP服务

在test-1上

yum install chrony -y
vi /etc/chrony.conf
注释掉
#server 0.centos.pool.ntp.org iburst
#server 1.centos.pool.ntp.org iburst
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst
添加
server ntp.aliyun.com iburst #使用阿里ntp
allow 59.64.78.64/24 #允许网段其他节点同步时间

保存退出之后

systemctl enable chronyd.service
systemctl start chronyd.service
chronyc sources

在test-2上

yum install chrony -y
vi /etc/chrony.conf
注释掉
#server 0.centos.pool.ntp.org iburst
#server 1.centos.pool.ntp.org iburst
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst
添加
server controller iburst #同步test-1节点

保存退出之后

systemctl enable chronyd.service
systemctl start chronyd.service
chronyc sources

安装yum库（所有节点）

在test-1，test-2都安装

yum install centos-release-openstack-train -y
yum install https://rdoproject.org/repos/rdo-release.rpm -y
yum upgrade -y
yum install python-openstackclient -y #客户端安装

提前设置一下环境变量

在test-1上设置
先在命令行输入openssl rand -hex 10，生成一个随机密码
然后

export ADMIN_PASS=fc05e1929b2c057a4098
export CINDER_DBPASS=BBDERS1@bbdops.com
export CINDER_PASS=fc05e1929b2c057a4098

export RABBIT_PASS=fc05e1929b2c057a4098

source /etc/profile使之生效

安装MySQL

查看 rpm -qa | grep mariadb 如果有东西出现就rpm -e --nodeps mariadb….. 我这里是rpm -e --nodeps mariadb-config-3:10.3.20-3.el7.0.0.rdo1.x86_64做了一个删除操作

下载MySQL

wget https://repo.mysql.com/mysql80-community-release-el7-3.noarch.rpm

yum本地安装

sudo yum localinstall mysql80-community-release-el7-3.noarch.rpm

sudo yum install mysql-community-server -y

启动mysql并设置开机启动

sudo systemctl enable mysqld
sudo systemctl start mysqld

查看初始密码

grep 'temporary password'  /var/log/mysqld.log

进入命令行

mysql -u root -p

输入刚才查到的密码
进入到mysql命令行

修改密码

mysql> ALTER USER root@localhost identified by '8sVQxyAzym-w';

最后那部分为自定的密码

退出MySQL：ctrl+z

设置免密登录：vim /etc/my.cnf 添加

[client]
host=127.0.0.1
user=root
password=8sVQxyAzym-w

输入mysql

创建镜像测试

下载测试镜像cirros

wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img

上传到glance

openstack image create "cirros" --disk-format qcow2 --container-format bare --public < cirros-0.3.4-x86_64-disk.img

创建实例类型：
创建名为 flavor1、ID 为 1234、内存为 512MB、硬盘为 1GB、虚拟内核数量为 1 的云主机类型；

. admin-openrc
nova flavor-create flavor1 1234 512 1 1

然后从用户界面->管理员->计算->实例类型查看

总结

OpenStack的安装步骤非常多，且官方文档也不一定是完全对的（毕竟版本一直在更替，但安装文档他们可能忘记更新了），因此中间遇到问题是很正常的事情，本文也踩了不少坑，如果有一些奇奇怪怪的问题也欢迎联系，一起讨论问题并解决（当然Google一下大概率解决的更快）
