一、基础环境

OpenStack云计算环境的搭建是基于虚拟机的多节点Linux网络环境基础上搭建起来的，所以需要我们先搭建好集群环境。（基础环境搭建参考：基于虚拟机的多节点Linux网络环境搭建）

1.基本环境信息回顾

操作系统：CentOS7

controller节点IP：192.168.43.199
compute节点IP：192.168.43.74
neutron节点IP：192.168.43.180

说明：这里我的IP之所以和基于虚拟机的多节点Linux网络环境搭建这篇文章中的不一样，是因为我重新搭建了环境，IP也重新分配了，所以后续的IP就以我这里列出来的为主。

2.基本环境网络测试

我们先测试一下网络的连通性，具体过程见：基于虚拟机的多节点Linux网络环境搭建

如果网络没问题，我们就可以开开心心的继续下面的内容啦！

二、实现过程

1.配置阿里yum源（所有节点）

备份

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

下载

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
或者
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

2.安装NTP时钟服务（所有节点）

• controller节点

安装软件包

yum install chrony -y

编辑vi /etc/chrony.conf文件，配置时钟源同步服务端

server  controlelr  iburst      ##所有节点向controller节点同步时间
allow 192.168.43.0/199         ##设置时间同步网段

设置NTP服务开机启动

systemctl enable chronyd.service
systemctl start chronyd.service

• compute节点和neutron节点

安装软件包

yum install chrony -y

编辑vi /etc/chrony.conf文件，配置所有节点指向controller同步时间

server  controlelr  iburst

设置NTP服务开机启动

systemctl enable chronyd.service
systemctl start chronyd.service

• 验证时钟同步服务

chronyc sources

3.openstack服务安装、配置（所有节点）

下载安装openstack软件仓库（queens版本）

yum install centos-release-openstack-queens -y

更新所有节点软件包

yum upgrade

安装openstack client端

yum install python-openstackclient -y

安装openstack-selinux

yum install openstack-selinux -y

4.安装数据库（controller节点）

安装软件包

yum install mariadb mariadb-server python2-PyMySQL -y

编辑/etc/my.cnf.d/mariadb-server.cnf并完成以下配置（说明：bind-address使用controller节点的管理IP）

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
bind-address = 192.168.43.199
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

设置服务开机启动

systemctl enable mariadb.service
systemctl start mariadb.service

通过运行mysql_secure_installation脚本来保护数据库服务。（说明：运行命令后，需要先输入密码，我们可以不用输入直接回车继续即可。）

5.安装、配置RabbitMQ（controller节点）

安装配置消息队列组件

yum install rabbitmq-server -y

设置服务开机启动

systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service
