OpenStack入门体验

一、使用本地仓库离线安装

1、系统基本环境设置

bash 复制代码

setenforce 0
sed -i '/^SELINUX=/s/enforcing/disabled/' /etc/selinux/config
systemctl stop firewalld
systemctl disable firewalld
systemctl stop NetworkManager
systemctl disable NetworkManager
hostnamectl set-hostname openstack
bash

echo '192.168.10.101 openstack'>>/etc/hosts

echo "net.ipv4.ip_forward = 1">> /etc/sysctl.conf
sysctl -p

2、为系统设置本地仓库

bash 复制代码

vim /etc/yum.repos.d/CentOS-Base.repo
[Virt]
name=CentOS-$releasever - Base
baseurl=http://mirrors.aliyun.com/centos/7.9.2009/virt/x86_64/kvm-common/
gpgcheck=0




vim /etc/yum.repos.d/train.repo

[train]
name=centos-train
baseurl=https://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-train/
gpgcheck=0
enabled=1

yum clean all


yum makecache

3、安装部署工具

bash 复制代码

yum -y install openstack-packstack
rm -rf /etc/yum.repos.d/elrepo.repo

4、一键安装

bash 复制代码

packstack --allinone

5、设置桥接网络

bash 复制代码

cd /etc/sysconfig/network-scripts/
cp ifcfg-ens33 ifcfg-br-ex
vim ifcfg-br-ex
