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"
