openstack云平台部署（脚本版）

news 来源：原创 2025/6/11 18:38:05

一.准备工作

原版请看置顶文章（此文章为写脚本自动搭建）

云平台需要两个节点，一个controller（控制节点），一个compute（计算节点）环境要求：VM虚拟机2台，镜像为centos7或7.5。

本指南使用的ip

控制节点(controller)：

一块100G的硬盘。两块网卡，两块网卡第一块网卡IP地址为192.168.100.10，第二块网卡IP地址为192.168.200.10。（编辑时用的是60G硬盘）

计算节点(compute)：

一块100G硬盘和一块50G硬盘。两块网卡第一块网卡IP地址为192.168.100.20，第二块网卡IP地址为192.168.200.20。（编辑时用的60G+20G两块硬盘）

本指南运用的镜像

1.通过百度网盘分享的文件：CentOS-7-x86_64-DVD-2009.iso
链接：https://pan.baidu.com/s/1VqYqutsstDwdt7w8g4tjjg
提取码：dy7c
2.通过百度网盘分享的文件：CentOS-7.5-x86_64-DVD-1804.iso
链接：https://pan.baidu.com/s/1pzt1_iZ0Lph69Llvo_2ILQ
提取码：37ss
3.通过百度网盘分享的文件：chinaskills_cloud_iaas.iso
链接：https://pan.baidu.com/s/1EDlE-9bH83yGmvQtifLlvw
提取码：2e16

二.配置虚拟机

1.controller控制节点

1.修改controller（控制节点）主机名

2.1修改第一块网卡

按insert进入编辑模式，编辑完后esc加冒号wq保存退出

2.2修改第二块网卡

重启网卡，使网卡生效

使用finalshell连接controller（为了更好的使用）

2.compute节点

第一块网卡配置如下：

第二块网卡配置如下：

重启网卡使配置生效

三.正式开始搭建openstack云平台

controller节点配置：

1.上传centos7镜像和iaas镜像

上传成功！

2.编写脚本

vim 1.sh

#!/bin/bash
systemctl stop firewalld
systemctl disable firewalld
setenforce 0
sed -i "s/SELINUX=enforcing/SELINUX=permissive/g" /etc/selinux/config
rm -rf /etc/yum.repos.d/*
cat > /etc/yum.repos.d/local.repo << EOF
[centos]
name=centos
baseurl=file:///opt/centos
gpgcheck=0
enabled=1

[iaas]
name=iaas
baseurl=file:///opt/openstack/iaas-repo
gpgcheck=0
enabled=1
EOF
yum install -y vim vsftpd iaas-xiandian
sed -i "s/anonymous_enable=NO/anonymous_enable=YES/g" /etc/vsftpd/vsftpd.conf
sed -i "s/anonymous_root=\/var\/ftp/anonymous_root=\/opt\/1/g" /etc/vsftpd/vsftpd.conf
systemctl restart vsftpd
systemctl enable vsftpd

6.修改脚本

compute节点设置

编写脚本

vim 1.sh

#!/bin/bash
systemctl stop firewalld
systemctl disable firewalld
setenforce 0
sed -i "s/SELINUX=enforcing/SELINUX=permissive/g" /etc/selinux/config
rm -rf /etc/yum.repos.d/*
cat > /etc/yum.repos.d/local.repo << EOF
[centos]
name=centos
baseurl=file:///opt/centos
gpgcheck=0
enabled=1

[iaas]
name=iaas
baseurl=file:///opt/openstack/iaas-repo
gpgcheck=0
enabled=1
EOF
yum install -y vim vsftpd iaas-xiandian
fdisk /dev/sdb << EOF
n
p

+10G

EOF

4.修改脚本
将controller节点的脚本复制至compute节点

[root@compute ~]# scp 192.168.100.10:/etc/xiandian/openrc.sh /etc/xiandian/openrc.sh 
The authenticity of host '192.168.100.10 (192.168.100.10)' can't be established.
ECDSA key fingerprint is SHA256:3fUEo7XuafRBPMtY2rSnpjKOdGSrLnE68O2aZAXEp6o.
ECDSA key fingerprint is MD5:4b:73:20:24:30:ad:6a:31:86:fa:26:55:47:92:99:cc.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.100.10' (ECDSA) to the list of known hosts.

openrc.sh                                                            100% 3820     1.9MB/s   00:00

修改openrc.sh脚本中本机Ip地址

四.刷脚本
注：刷脚本前可以快照

controller节点：

[root@controller ~]# iaas-pre-host.sh        #刷完该脚本后需要重启
 
[root@controller ~]# iaas-install-mysql.sh
 
[root@controller ~]# iaas-install-keystone.sh
 
[root@controller ~]# source /etc/keystone/admin-openrc.sh         #使环境生效
 
[root@controller ~]# iaas-install-glance.sh
 
[root@controller ~]# iaas-install-nova-controller.sh
 
[root@controller ~]# iaas-install-neutron-controller.sh
 
[root@controller ~]# iaas-install-dashboard.sh

compute节点：

[root@compute ~]# iaas-pre-host.sh         #刷完该脚本后需要重启
 
[root@compute ~]# iaas-install-nova-compute.sh
 
[root@compute ~]# iaas-install-neutron-compute.sh
