一.配置基础环境

1. 1.基础环境:我们首先要准备两个虚拟机一个为controller节点(控制节点)，一个为compute节点(计算节点)，控制节点为两个镜像一个centos一个iaas，硬盘要准备两个，一个100GB，一个50GB，加上两个网络，一个为仅主机(vm1)，一个为NAT(vm2)。计算节点如上但少一个iaas镜像和50GB硬盘。以上所有环境在VM虚拟机基础设置配置。
2. controller进入虚拟机配置:进入命令界面我们需要做修改他的主机名和配置基础网络

controller节点配置基础

［root@localhost /］>hostnamectl set-hostname controller ；bash

［root@controller /］>nmtui 更改IP地址，第一张网卡(仅主机)为192.168.10.10/24的网络不用加入网关，第二张网卡(NAT)为192.168.20.10/24的网络添加网关

［root@controller /］>mkdir /opt/centos

［root@controller /］>mkdir /opt/iaas

［root@controller /］>mount /dev/sr1 /opt/centos

［root@controller /］>mount /dev/sr0 /opt/iaas

［root@controller /］>rm -rf /etc/yum.repos.d/Centos-*

compute节点配置基础

［root@localhost /］>hostnamectl set-hostname compute ;bash

［root@compute/］>nmtui  更改IP地址，第一张网卡(仅主机)为192.168.10.20/24的网络不用加入网关，第二张网卡(NAT)为192.168.20.20/24的网络添加网关

免密连接

［root@controller /］>ssh-keygen

［root@controller /］>ssh-copy-id 192.168.10.20

配置hosts

［root@controller /］>vi /etc/hosts

192.168.10.10 controller

192.168.10.20 compute

［root@controller /］>scp /etc/hosts compute:/etc/hosts

配置防火墙(两个节点都要)

［root@controller /］>systemctl stop firewalld

［root@controller /］>systemctl disable firewalld

［root@controller /］>setenforce 0

［root@controller /］>vi /etc/selinux/conf

给类型改成disabled

controller节点配置yum源内容

［root@controller /］>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/iaas-repo

gpgcheck=0

enabled=1

［root@controller /］>yum clean all

［root@controller /］>yum repolist

［root@controller /］>yum install -y vsftpd openstack-iaas 

［root@controller /］>vi /etc/vsftpd/vsftp.conf

anon_root=/opt

［root@controller /］>systemctl start vsftpd 

［root@controller /］>systemctl enable vsftpd

［root@controller /］>scp /etc/yum.repod.s/local.repo compute:/etc/yum.repod.s/ftp.repo

compute节点配置yum源内容

［root@compute /］>rm -rf /etc/yum.repod.s/Centos-*

［root@compute /］>vi /etc/yum.repod.s/ftp.repo

[centos]

name=centos

baseurl=ftp://controller/centos

gpgcheck=0

enabled=1

[iaas]

name=iaas

baseurl=ftp://controller/iaas/iaas-repo

gpgcheck=0

enabled=1

［root@compute /］>yum clean all

［root@compute /］>yum repolist

［root@compute /］>yum install -y openstack-iaas

在controller配置opensl.sh内容

［root@controller /］>sed -i 's/^#//g' /etc/openstack/openrc.sh

［root@controller /］>vi /etc/openstack/openrc.sh

点击esc回到命令模式输入

%s/PASS=/PASS=000000/g 然后回车

之后进入编辑模式更改内容

#--------------------system Config--------------------##

#Controller Server Manager IP. example:x.x.x.x

HOST_IP=192.168.10.10

 

#Controller HOST Password. example:000000

#--------------------Chrony Config-------------------##

剩下的不用添加这边没有加入硬盘分区

［root@controller /］>scp /etc/openstack/opn compute:/etc/openstack/openrc.sh

开始刷脚本(按照顺序刷)

两个节点同时刷iaas-per-host.sh

controller节点需要刷的脚本有

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-heat.sh

compute节点需要刷的脚本有

iaas-install-nova-compute.sh

iaas-install-netron-compute.sh

验证云平台安装

脚本安装完成，在浏览器输入http://192.168.10.10/dashboard回车进行验证服务
