前言
本篇文章会介绍openstack的安装、openstack各组件的配置和功能、还会演示openstack云主机的创建流程，整篇文章花费一天时间完成，万字长文，需要的可以关注，相互学习，本篇文章总体分为三个部分：
第一部分讲解openstack安装
第二部分讲解openstack组件，包括：
keystone glance nova neutron dashboard 第三部分讲解openstack使用，如：
创建云主机 创建公网 创建子网 配置路由 配置防火墙 配置安全策略 创建云主机存储卷等 openstack简介
Openstack是一个开源的云平台管理项目，可以用于构建公有云或者私有云平台，提供了基础设施及服务（Iaas）的解决方案，OpenStack是一个云操作系统，通过数据中心可控制计算、存储、网络等资源池,OpenStack覆盖了网络、虚拟化、操作系统、服务器等各个方面，通过openstack可以启动，分配和管理虚拟机资源,所有的管理也都可以通过前端界面就可以完成。我们部署openstack之后，可以通过这个平台创建各个不同版本的虚拟机，如centos，windows等系统，可以按需分配cpu，内存，磁盘给这些虚拟机，同时还可以提供网络支持。
第一部分：openstack安装篇
操作系统版本选择centos7.6或者更高版本
controller节点：三个60G硬盘 ，8G内存/4核CPU，两块桥接网卡
computer节点：两个60G硬盘 ，6G内存/4核CPU/，两块桥接网卡
机器规划
controller节点：
ens33：192.168.0.100，提供浮动ip的，也就是出网地址（能访问baidu.com） ens37：192.168.0.200，内网之间通信用 computer节点：
ens33：192.168.0.110，提供浮动ip的，也就是出网地址 ens37：192.168.0.210，内网之间通信用 修改虚拟机的ip变成静态ip，controller节点的配置如下所示：
cat /etc/sysconfig/network-scripts/ifcfg-ens33
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.0.100
NETMASK=255.255.255.0
GATEWAY=192.168.0.1
DNS1=8.8.8.8
cat /etc/sysconfig/network-scripts/ifcfg-ens37
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens37
DEVICE=ens37
ONBOOT=yes
IPADDR=192.168.0.200
NETMASK=255.255.255.0
GATEWAY=192.168.0.1
DNS1=8.8.8.8
修改配置文件之后需要重启网络服务才能使配置生效，重启网络服务命令如下：
service network restart
注：ifcfg-ens33文件配置解释：
IPADDR=192.168.0.100
#ip地址，需要跟自己电脑所在网段一致
NETMASK=255.255.255.0
#子网掩码，需要跟自己电脑所在网段一致
GATEWAY=192.168.0.1
#网关，在自己电脑打开cmd，输入ipconfig /all可看到
DNS1=192.168.0.1
#DNS，在自己电脑打开cmd，输入ipconfig /all可看到
配置hosts文件，各个节点保持一致
cat /etc/hosts
在最后一行添加如下内容
192.168.0.200 controller
192.168.0.210 computer
配置yum源，各个节点操作
（1）备份原来的yum源
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
（2）下载阿里的yum源
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
（3）生成新的yum缓存
yum makecache fast
（4）清理yum缓存
yum clean all
（5）更新yum源
yum -y update
初始化，各个节点操作
yum -y install wget net-tools nfs-utils lrzsz gccgcc-c++ make cmake libxml2-devel openssl-devel curl curl-devel unzip sudo ntplibaio-devel wget vim ncurses-devel autoconf automake zlib-devel python-devel epel-release lrzsz openssh-server telnet
关闭防火墙、networkmanager，iptables，各个节点操作
systemctl stop firewalld && systemctl disable firewalld && systemctl stop NetworkManager && systemctl disable NetworkManager && systemctl stop iptables && systemctl disable iptables
关闭selinux，各个节点操作
关闭selinux，设置永久关闭，这样重启机器selinux也处于关闭状态
修改/etc/sysconfig/selinux和/etc/selinux/config文件，把
SELINUX=enforcing变成SELINUX=disabled，也可用下面方式修改：
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/sysconfig/selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
配置主机名
192.168.0.100上操作
hostnamectl set-hostname controller
192.168.0.110上操作
hostnamectl set-hostname computer
做时间同步，各个节点操作
ntpdate cn.pool.ntp.org
配置无密码登陆，各个节点操作
ssh-keygen -t rsa
#一直回车即可
ssh-copy-id -i .ssh/id_rsa.pub controller
ssh-copy-id -i .ssh/id_rsa.pub computer
开始安装openstack
openstack软件包在百度网盘，链接如下：
链接：https://pan.baidu.com/s/1dHDF4WxvNoqcJd90mDxrbA 提取码：yz56 （1）上传openstack离线软件包到root目录下（在controller和computer节点操作）
在root下创建一个目录openstack，然后把软件包解压到这个目录下
mkdir /root/openstack && cd openstack && tar zxvf /root/openstack_N.tar.gz
（2）解压之后会出现一个openstack目录，把openstack目录整体移动到/下（controller和computer节点操作）
mv openstack /
（3）重新配置yum源（controller和computer节点都操作）
cd /etc/yum.repos.d/ && mkdir bak && mv CentOS-* bak/ && mv epel* bak/
cp bak/CentOS-Base.repo ./
（4）生成一个新的openstack的yum源
cat <<EOF > /etc/yum.repos.d/openstack.repo
[openstack]
enable=1
gpgcheck=0
baseurl=file:///openstack
EOF
yum makecache
安装openstack应答文件（controller节点操作）
yum install centos-release-openstack-newton -y
在controller和computer节点执行如下一条命令
cd /etc/yum.repos.d && mv *.repo bak/ && mv bak/openstack.repo ./ && cp bak/CentOS-Base.repo ./
这样在/etc/yum.repos.d下只有如下两个repo文件，这样才可以确保后面安装成功：
CentOS-Base.repo openstack.repo 接下来的操作继续在controller节点执行
yum makecache
yum install openstack-packstack -y
cd /root
packstack --gen-answer-file=openstack.txt
#这样会生成一个应答文件openstack.txt
（1）查看openstack应答文件内容
grep -vE '^$|^#' openstack.txt

#computer节点的ens37网卡的ip
CONFIG_NETWORK_HOSTS=192.168.0.210

看到y的表示是需要安装的组件
安装openstack组件-controller节点操作
基于应答文件安装openstack组件，按如下命令操作：
packstack--answer-file=openstack.txt
上面命令执行成功之后再回到conputer节点执行如下操作：
cd /etc/yum.repos.d && mv CentOS-Ceph-Jewel.repo CentOS-OpenStack-newton.repo CentOS-QEMU-EV.repo CentOS-Storage-common.repo bak/
（1）安装过程需要查看iptables状态，在controller和computer节点
systemctl status iptables
如果发现iptables处于active状态，需要停掉
systemctl stop iptables
（2）看到如下说明安装成功
