二、Bandwidthd服务器安装配置
（1）首先安装CentOS 6.4，从 网易的开源镜像站点，很快就可以下载了。推荐下载这个minimal的版本，300M左右。
（2）服务器需要2块网卡
eth0配置为管理地址，eth1网卡不需要配置IP，直接插到交换机的镜像口上。
（3）安装Bandwidthd支持软件包
yum install gcc cpp glibc glibc-devel gcc-c++
yum install libpcap libpcap-devel libpng libpng-devel gd gd-devel
yum install httpd mod_ssl
service httpd start
chkconfig httpd on
安装wget下载工具
yum install wget
（4）下载Bandwidthd代码
下载地址：%202.0.1/bandwidthd-2.0.1.tgz
用wget下载：
wget %202.0.1/bandwidthd-2.0.1.tgz
tar -zxvf bandwidthd-2.0.1.tgz
解压缩完毕后，就准备编译安装了
cd bandwidthd-2.0.1
