1.实验环境搭建
使用镜像：
CentOS-7.5-x86_64-DVD-1804.iso
chinaskills_cloud_iaas.iso
VM版本15.5
有需要实验镜像的小伙伴请私信
所有虚拟机CPU必须开启虚拟化功能：
2.配置主机名和网络
2.1 配置网络
#vi /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
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=eth0
UUID=72c226b2-f8c0-4922-8349-67cb7b0758df
DEVICE=eth0
ONBOOT=yes
IPADDR=172.17.10.10/172.17.100.20(controller/compute)
PREFIX=24
GATEWAY=172.17.10.1
IPV6_PRIVACY=no
2.2 修改主机名
#hostnamectl set-hostname controller/compute
#bash
#hostnamectl -----查看主机名服务相关信息
3.yum源配置
controller端：
[root@controller ~]# cd /etc/yum.repos.d/
[root@controller yum.repos.d]# ls
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo
CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo
[root@controller yum.repos.d]# rm -rf *
[root@controller yum.repos.d]# ll
total 0
[root@controller yum.repos.d]# ls
[root@controller yum.repos.d]# vi file.repo
[root@controller yum.repos.d]# more file.repo
[centos]
name=centos
baseurl=file:///opt/centos/
gpgcheck=0
enabled=1
[iaas-repo]
name=iaas-repo
baseurl=file:///opt/openstack/iaas-repo/
gpgcheck=0
enabled=1
compute端：
[centos]
name=centos
baseurl=ftp://172.17.10.10/centos/
gpgcheck=0
enabled=1
[iaas-repo]
name=iaas-repo
baseurl=ftp://172.17.10.10/openstack/iaas-repo
gpgcheck=0
enabled=1
在controller节点上传CentOS-7.5-x86_64-DVD-1804.iso、chinaskills_cloud_iaas.iso两个镜像。（这里不做演示)
上传软件可用：WinSCP、Xftp、SecureFX
3.1 挂载CentOS-7.5-x86_64-DVD-1804.iso
[root@controller ~]# mount -o loop CentOS-7.5-x86_64-DVD-1804.iso /mnt/
[root@controller ~]# cp -rvf /mnt/* /opt/centos/
[root@controller ~]# umount /mnt/
3.2 挂载chinaskills_cloud_iaas.iso
[root@controller ~]# mount -o loop chinaskills_cloud_iaas.iso /mnt/
[root@controller ~]# cp -rvf /mnt/* /opt/openstack/
[root@controller ~]# umount /mnt/
3.3 清除缓存，验证yum源配置
[root@controller ~]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: centos iaas-repo
Cleaning up everything
Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos
Cleaning up list of fastest mirrors
[root@controller ~]# yum repolist
Loaded plugins: fastestmirror
Determining fastest mirrors
centos | 3.6 kB 00:00:00
iaas-repo | 2.9 kB 00:00:00
(1/3): centos/group_gz | 166 kB 00:00:00
(2/3): iaas-repo/primary_db | 1.4 MB 00:00:00
(3/3): centos/primary_db | 3.1 MB 00:00:00
repo id repo name status
centos centos 3,971
iaas-repo iaas-repo 3,232
repolist: 7,203
4.搭建ftp
[root@controller ~]# yum install vsftpd -y
4.1 编辑vsftp配置文件，添加如下内容
[root@controller ~]# vi /etc/vsftpd/vsftpd.conf
anon_root=/opt/
4.2 启动ftp服务，并设置开机自启动
[root@controller ~]# systemctl start vsftpd
[root@controller ~]# systemctl enable vsftpd
Created symlink from /etc/systemd/system/multi-user.target.wants/vsftpd.service to /usr/lib/systemd/system/vsftpd.service.
5 配置域名解析、关闭防火墙、永久关闭Selinux
5.1 配置域名解析
[root@controller ~]# vi /etc/hosts
添加如下内容：
172.17.10.10 controller
172.17.10.20 compute
[root@controller ~]# scp /etc/hosts [email protected]:/etc/
5.2 controller和compute都永久关闭防火墙以及Selinux
[root@controller ~]# systemctl stop firewalld
[root@controller ~]# systemctl disable firewalld
[root@controller ~]# vi /etc/sysconfig/selinux
根据题目要求修改为Permissive或者disabled。
6. 磁盘分区

将openrc.sh拷贝到compute节点下
[root@controller ~]# scp /etc/xiandian/openrc.sh root@compute:/etc/xiandian/
修改INTERFACE_IP=为comput的地址
8.使用脚本部署openstack平台
8.1 双节点执行iaas-pre-host.sh
[root@controller ~]# iaas-pre-host.sh
执行完成后，reboot重启系统。
8.2 在controller节点上执行iaas-install-mysql.sh
1.|[root@controller ~]# iaas-install-mysql.sh
8.3 执行iaas-install-keystone脚本
[root@controller ~]# iaas-install-keystone.sh
8.4 安装Glance服务
[root@controller ~]# source /etc/keystone/admin-openrc.sh
[root@controller ~]# iaas-install-glance.sh
上传镜像
[root@controller ~]# source admin-openrc.sh
[root@controller ~]# glance image-create --name "CentOS7.5" --disk-format qcow2 --container-format bare --progress < /opt/openstack/images/CentOS_7.5_x86_64_XD.qcow2
8.5 双节点执行脚本安装Nova服务
#Controller节点
执行脚本iaas-install-nova-controller.sh进行安装
#Compute节点
执行脚本iaas-install-nova-compute.sh进行安装
8.6 双节点执行脚本安装Neutron服务
#Controller节点
执行脚本iaas-install-neutron-controller.sh进行安装
#Compute节点
执行脚本iaas-install-neutron-compute.sh进行安装
8.7 controller端安装Dashboard服务
[root@controller ~]# iaas-install-dashboard.sh
安装完仪表盘服务后，我们可以移步到浏览器中去访问openstackweb端了
打开浏览器访问Dashboard
http://controller（或本机内网ip）/dashboard
注：检查防火墙规则，确保允许http服务相关端口通行，或者关闭防火墙。
8.8 通过脚本安装cinder服务以及swift服务
#Controller
执行脚本iaas-install-cinder-controller.sh进行安装
#Compute节点
执行脚本iaas-install-cinder-compute.sh进行安装
#Controller
执行脚本iaas-install-swift-controller.sh进行安装
#Compute节点
执行脚本iaas-install-swift-compute.sh进行安装
至此，openstack基础搭建已基本完成。
