openstack私有云搭建(省赛)
openstack私有云保姆级搭建
1.准备工作
(1) 镜像准备 CentOS-7-x86_64-DVD-2009.iso、chinaskills_cloud_iaas_v2.0.3.iso
切记不要使用这种带Minimal的系统镜像 要不然后面会报错 哪个版本都不行 例如 
(2) 两台虚拟机，配置两张网卡，第一张仅主机模式，第二张NAT模式，配置根据自身电脑来，不低于2G运行内存，虚拟机镜像使用 CentOS-7-x86_64-DVD-2009.iso，版本太低会出问题，
(3) MobaXterm远程连接工具
(4) 每台虚拟机装备三块硬盘，后面会用到
(5) 因为比赛是一个无网环境，所以我们自己电脑上第二张网卡可以不用管
| 主机名 | ens33 | ens34 | root密码 |
| controller | 192.168.100.10 | 无 | 000000 |
| compute | 192.168.100.20 | 无 | 000000 |
如图
2.配置两台主机的ens33(仅主机模式)网络
(1) 配置前检查网卡的配置 确保后面的ip是在这个网段下
(2) controller主机 如果虚拟机是克隆过来的 可以把UUID那一行删掉
vi /etc/sysconfig/network-scripts/ifcfg-ens33
重启网络
systemctl restart network
(3) compute主机 这里把UUID删除了
vi /etc/sysconfig/network-scripts/ifcfg-ens33
重启网络
systemctl restart network
(4) 最后使用远程工具连接(MobaXterm)
3.修改主机名和添加域名解析
controller 和compute 主机
(1) 修改主机名
# controller 主机
hostnamectl set-hostname controller
bash
# compute 主机
hostnamectl set-hostname compute
bash(2) 添加本地域名解析
vi /etc/hosts 打开这个文件并添加内容
写完后把文件复制一份给compute
scp /etc/hosts compute:/etc/hosts
4.配置本地yum源
controller 主机
(1) 将两个镜像上传到 /opt/ 目录下
(2) 在/opt/ 目录下创建两个文件夹 centos和iaas
mkdir /opt/centos
mkdir /opt/iaas
(3) 把自带的yum源文件删掉
rm /etc/yum.repos.d/* -f
(4) 挂载镜像
# 挂载centos2009镜像到/mnt/目录
mount -o loop /opt/CentOS-7-x86_64-DVD-2009.iso /mnt/
# 将文件复制到/opt/centos
cp -rvf /mnt/* /opt/centos/
# 结束挂载
umount /mnt/
# 挂载iaas镜像到/mnt/目录
mount -o loop /opt/chinaskills_cloud_iaas_v2.0.3.iso /mnt/
# 将文件复制到/opt/iaas
cp -rvf /mnt/* /opt/iaas/
# 结束挂载
umount /mnt/
(5) 编写yum源文件
vi /etc/yum.repos.d/local.repo
写入以下内容
[centos]
name=centos
gpgcheck=0
enabled=1
baseurl=file:///opt/centos
[iaas]
name=iaas
gpgcheck=0
enabled=1
baseurl=file:///opt/iaas/iaas-repo
清除yum源缓存
yum clean all
重新加载yum源
yum repolist
成功展示
vsftpd安装和配置( compute通过vsftpd来配置域名本地源 )
controller主机
(1) 安装vsftpd
yum install -y vsftpd
(2) 配置vsftpd并重启服务
打开该文件
vi /etc/vsftpd/vsftpd.conf
添加一行配置，可以写在最上方
anon_root=/opt/
重启服务，并设置成开机自启
systemctl start vsftpd
systemctl enable vsftpd
(3)关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
vi /etc/selinux/config
cmpute 主机
(1) 删除本地自带yum源文件
rm /etc/yum.repos.d/* -f
(2) 编写yum源文件
vi /etc/yum.repos.d/ftp.repo
添加以下内容
[centos]
name=centos
gpgcheck=0
enabled=1
baesurl=ftp://controller/centos
[iaas]
name=iaas
gpgcheck=0
enabled=1
baseurl=ftp://controller/iaas/iaas-repo
清除yum源缓存
yum clean all
重新加载yum源
yum repolist
成功后会显示软件包数量和controller一样
5.安装openstack，并写入配置文件
(1) 安装openstack (controller和compute 都要安装)
yum install -y openstack-iaas
(2) 配置文件(controller)完成后复制一份到compute
vi /etc/openstack/openrc.sh
进入后在底下命令行模式执行两个命令
:%s/#/ # 清除每一行第一个#
:%s/PASS=/PASS=000000 # 替换

(3) 复制一份给compute
scp /etc/openstack/openrc.sh compute:/etc/openstack/openrc.sh
6.配置无密钥节点
controller主机
ssh-keygen 执行后一直回车就行
ssh-copy-id compute 执行后输入compute节点密码000000
compute主机
ssh-keygen 执行后一直回车就行
ssh-copy-id controller 执行后输入controller节点密码000000
7.执行脚本
(1) 先执行初始化脚本
1. 两台主机都要执行 先执行完controller在执行compute
iaas-pre-host.sh
2.两台都执行完后重启主机
init 6
3.重启后会出现这个标识
(2) 按顺序执行其他脚本，还是先执行完controller在执行compute
1.controller 主机 前七个最好安装一下 后面的看需求可以不安装
iaas-install-mysql.sh
iaas-install-keystone.sh
iaas-install-glance.sh
iaas-install-placement.sh
iaas-install-nova-controller.sh
iaas-install-neutron-controller.sh
iaas-install-dashboard.sh
iaas-install-cinder-controller.sh
iaas-install-swift-controller.sh
iaas-install-heat.sh
iaas-install-manila-controller.sh
iaas-install-cloudkitty.sh
iaas-install-barbican.sh
2.compute 主机 确保compute安装的组件 controller必须是已安装的状态
iaas-install-nova-compute.sh
iaas-install-neutron-compute.sh
iaas-install-cinder-compute.sh
iaas-install-swift-compute.sh
iaas-install-manila-compute.sh
8.最后基础搭建已经完成 可以登录网站查看效果
