部署架构
一台控制节点和一台计算节点组成简单架构OpenStack平台，控制节点安装MySQL、Keystone、Glance、Nova、Neutron、Dashboard等服务，主要作为认证、镜像管理节点，以及提供Nova和Neutron服务的管理节点。提供Dashboard界面服务。计算节点主要安装nova-compute和Neutron服务，Nova服务提供云主机服务，Neutron提供网络服务。通过Shell脚本进行OpenStack平台部署，脚本分为控制节点脚本和计算节点脚本，对应节点执行部署脚本。
规划节点
安装OpenStack平台的2个节点规划
| 第一张网卡 IP | 主机名 | 节点 |
| 192.168.100.10 | controller | 控制节点 |
| 192.168.100.20 | compute | 计算节点 |
-----------------------------------------------------------------------------------------------------
| 第二张网卡 IP | 主机名 | 节点 |
| 192.168.200.10 | controller | 控制节点 |
| 192.168.200.20 | compute | 计算节点 |
准备2台VMware虚拟机，手动最小化安装2台CentOS 7.2系统，作为OpenStack节点，第一张网卡为NAT模式，第二张网卡为仅主机模式，以及配置CPU虚拟化，计算节点至少使用4 GB内存，硬盘不小于50GB。第一张网卡网段为192.168.100.0/24，第二张网卡网段为192.168.200.0/24。并对compute节点分两个区为sda3与sda4。（教材是第一张网卡为仅主机模式，第二张网卡为NAT模式）
计算节点图片 略
输入重启网卡命令，并检查IP地址
systemctl restart network ip a
1. 基础环境配置
（1）IP地址配置控制节点和计算节点，安装最小化CentOS7.2操作系统，配置每个节点IP地址。并使用secureCRT进行连接。controller节点修改部分：
改名
hostnamectl set-hostname controller bash
修改hosts文件，把控制节点和计算节点加进去
vi /etc/hosts
192.168.100.10 controller 192.168.100.20 computer
配置防火墙规则
清除所以chains链
iptables -F iptables -X iptables -Z iptables-save
systemctl stop firewalld systemctl disable firewalld
配置yum源
先挂载centos镜像，创建文件夹，把挂载的镜像复制到新建的文件夹。
在挂载IAAS镜像包，把挂载的镜像复制到opt目录下即可。
mount -o loop /dev/cdrom /mnt/ mkdir /opt/centos cp -rf /mnt/* /opt/centos umount /mnt/
mount -o loop /dev/cdrom /mnt cp -rf /mnt/* /opt/ umount /mnt/
将网络yum源先移走，然后在自己创建一个yum文件
mv /etc/yum.repos.d/* /opt/ vi /etc/yum.repos.d/local.repo
[centos] name=centos baseurl=file:///opt/centos gpgcheck=0 enabled=1 [iaas] name=iaas baseurl=file:///opt/iaas-repo gpgcheck=0 enabled=1
使用命令验证yum是否配置正确
yum repolist
搭建ftp服务器
yum install -y vsftpd
vi /etc/vsftpd/vsftpd.conf
anon_root=/opt #添加
开启ftp服务，并设置开机自启动
systemctl start vsftpd systemctl enable vsftpd
控制节点下安装iaas-xiandian
yum install -y iaas-xiandian
编辑文件/etc/xiandian/openrc.sh 环境变量
vi /etc/xiandian/openrc.sh
改为以下内容
##--------------------system Config--------------------## ##Controller Server Manager IP. example:x.x.x.x HOST_IP=192.168.100.10 ##Controller Server hostname. example:controller HOST_NAME=controller ##Compute Node Manager IP. example:x.x.x.x HOST_IP_NODE=192.168.100.20 ##Compute Node hostname. example:compute HOST_NAME_NODE=compute ##--------------------Rabbit Config ------------------## ##user for rabbit. example:openstack RABBIT_USER=openstack ##Password for rabbit user .example:000000 RABBIT_PASS=000000 ##--------------------MySQL Config---------------------## ##Password for MySQL root user . exmaple:000000 DB_PASS=000000 ##--------------------Keystone Config------------------## ##Password for Keystore admin user. exmaple:000000 DOMAIN_NAME=demo ADMIN_PASS=000000 DEMO_PASS=000000 ##Password for Mysql keystore user. exmaple:000000 KEYSTONE_DBPASS=000000 ##--------------------Glance Config--------------------## ##Password for Mysql glance user. exmaple:000000 GLANCE_DBPASS=000000 ##Password for Keystore glance user. exmaple:000000 GLANCE_PASS=000000 ##--------------------Nova Config----------------------## ##Password for Mysql nova user. exmaple:000000 NOVA_DBPASS=000000 ##Password for Keystore nova user. exmaple:000000 NOVA_PASS=000000 ##--------------------Neturon Config-------------------## ##Password for Mysql neutron user. exmaple:000000 NEUTRON_DBPASS=000000 ##Password for Keystore neutron user. exmaple:000000 NEUTRON_PASS=000000 ##metadata secret for neutron. exmaple:000000 METADATA_SECRET=000000 ##External Network Interface. example:eth1 INTERFACE_NAME=eno33554960 ##First Vlan ID in VLAN RANGE for VLAN Network. exmaple:101 #minvlan= ##Last Vlan ID in VLAN RANGE for VLAN Network. example:200 #maxvlan= ##--------------------Cinder Config--------------------## ##Password for Mysql cinder user. exmaple:000000 CINDER_DBPASS=000000 ##Password for Keystore cinder user. exmaple:000000 CINDER_PASS=000000 ##Cinder Block Disk. example:md126p3 BLOCK_DISK=sdb1 ##--------------------Trove Config--------------------## ##Password for Mysql Trove User. exmaple:000000 TROVE_DBPASS=000000 ##Password for Keystore Trove User. exmaple:000000 TROVE_PASS=000000 ##--------------------Swift Config---------------------## ##Password for Keystore swift user. exmaple:000000 SWIFT_PASS=000000 ##The NODE Object Disk for Swift. example:md126p4.

划分空白磁盘，cinder存储和swift存储（计算节点）
查看计算机的磁盘名称
给sdb分区成cinder 盘
