openstack自動化搭建腳本

Openstack平臺部署+節點擴容

1)搭建腳本

 1 #!/bin/bash
 2 #openstack私有云平臺部署
 3 #腳本使用前提:三臺虛擬機openstack(ip地址:192.168.1.10,至少7G內存,50G硬盤),nova01(ip地址:192.168.1.11至少4G內存,100G硬盤),擴容用nova02(ip地址:192.168.1.12至少4G內存,100G硬盤);yum源正常;本次部署爲精簡版安裝
 4 source /root/moudle.sh
 5 while :
 6 do
 7 echo "#############################_menu_##################################"
 8 echo "1.openstack服務器環境部署與檢查"
 9 echo "2.nova環境部署與檢查"
10 echo "3.openstack服務安裝與登陸"
11 echo "4.openstack節點擴容"
12 echo "5.exit"
13 echo "#####################################################################"
14 read -p "請輸入您要部署的服務(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
