准备

OVF模板准备

• 安装 centos 6.8
• 初始化
• 部署vmware tools
• ovf 文件制作

#!/bin/bash

mycpu=$1
mymem=$2
mydisk=$3

if $1 || $2 || $3;
then
    echo "需要输入三个参数！"
    echo "例如如果想新建一个1核心1GB20GB的ovf，输入 ./xx 1 1 20"
    exit
fi

echo $mycpu $mymem $mydisk

ovfFileName="$mycpu.$mymem.$mydisk.ovf"
mfFileName="$mycpu.$mymem.$mydisk.mf"

cp -f $mydisk.ovf $ovfFileName
sed -i "s:mycpu:$mycpu:g" $ovfFileName
sed -i "s:mymem:$mymem:g" $ovfFileName

openssl dgst -sha1 $ovfFileName > $mfFileName
openssl dgst -sha1 $mydisk.vmdk >> $mfFileName

部署

一台虚拟机作为中转

• 资料打过去
• dnsmasq服务器

看看哪个机器上面跑哪些虚机

#!/usr/bin/env python
#coding:utf-8

import json



mental_server_type = {
    'cpu': 42,
    'mem': 200
}

# target，初始化一百台服务器

    machines.append(a)

在中转机器上执行OVF部署操作

• 批量部署脚本
• 每台机器上面执行

#!/bin/sh

cat create.txt | while read line
do
   echo $line
   vmname=`echo $line | awk -F, '{print $1}'`
   vmsize=`echo $line | awk -F, '{print $2}'`
   echo /vmfs/volumes/datastore1/vmware-ovftool/ovftool -dm=thin -ds=datastore1 '--net:bridged=VM Network' "--name=$vmname" http://192.168.0.88:1280/ovf/${vmsize}.ovf 'vi://root:fOgLnr1D@192.168.0.216'
done

部署完成后， 获取mac地址ip地址列表

#!/bin/sh
echo '' > /tmp/dhcp.txt
vim-cmd vmsvc/getallvms | grep vmx > /tmp/vmx.txt
cat /tmp/vmx.txt | while read line
do
   vmid=`echo $line | awk '{print $1}'`
   vmname=`echo $line | awk '{print $2}'`
   vmip=`echo $vmname | awk -F\- '{print $NF}'`
   vmip=`echo $vmip | awk -FP '{print "192.168.0."$NF}'`
   vmmac=`vim-cmd vmsvc/device.getdevices $vmid | grep macAddress | awk -F\" '{print $2}'`
   echo "$vmid $vmname $vmip $vmmac"
   echo "dhcp-host=$vmmac,$vmip" >> /tmp/dhcp.txt
done

cat /tmp/dhcp.txt
