openstack自动化搭建脚本

Openstack平台部署+节点扩容

1)搭建脚本

#!/bin/bash
#openstack私有云平台部署
#脚本使用前提:三台虚拟机openstack(ip地址:192.168.1.10,至少7G内存,50G硬盘),nova01(ip地址:192.168.1.11至少4G内存,100G硬盘),扩容用nova02(ip地址:192.168.1.12至少4G内存,100G硬盘);yum源正常;本次部署为精简版安装
source /root/moudle.sh
while :
do
echo "#############################_menu_##################################"
echo "1.openstack服务器环境部署与检查"
echo "2.nova环境部署与检查"
echo "3.openstack服务安装与登录"
echo "4.openstack节点扩容"
echo "5.exit"
echo "#####################################################################"
read -p "请输入您要部署的服务(1|2|3|4|5):" select
if [ "$select" == "1" ];then
    env_openstack
elif [ "$select" == "2" ];then
    env_nova
elif [ "$select" == "3" ];then
    install_openstack
elif [ "$select" == "4" ];then
    ext_nova
elif [ "$select" == "5" ];then
    exit
else
    echo "I AM SORRY"
    sleep 2
fi
done

2)脚本模块

#!/bin/bash
#函数定义
