openstack自动化搭建脚本
Openstack平台部署+节点扩容
1)搭建脚本
1 #!/bin/bash 2 #openstack私有云平台部署 3 #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 4 source /root/moudle.sh 5 while : 6 do 7 echo "#############################_menu_##################################" 8 echo "1.openstack服务器环境部署与检查" 9 echo "2.nova环境部署与检查" 10 echo "3.openstack服务安装与登录" 11 echo "4.openstack节点扩容" 12 echo "5.exit" 13 echo "#####################################################################" 14 read -p "请输入您要部署的服务(1|2|3|4|5):" select 15 if [ "$select" == "1" ];then 16 env_openstack 17 elif [ "$select" == "2" ];then 18 env_nova 19 elif [ "$select" == "3" ];then 20 install_openstack 21 elif [ "$select" == "4" ];then 22 ext_nova 23 elif [ "$select" == "5" ];then 24 exit 25 else 26 echo "I AM SORRY" 27 sleep 2 28 fi 29 done
