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..11至少4G内存,100G硬盘),扩容用nova02(ip地址:192.168..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 [ "$select" == "" ];then
     env_openstack
 elif [ "$select" == "" ];then
     env_nova
 elif [ "$select" == "" ];then
     install_openstack
 elif [ "$select" == "" ];then
     ext_nova
 elif [ "$select" == "" ];then
     exit
 else
     echo "I AM SORRY"
     sleep
 fi
 done

2)脚本模块

 #!/bin/bash
 #函数定义
