一、在CentOS6.4环境下编译Bandwidthd和Postgrsql需要注意顺序

（1）下载Postgrsql

    wget http://ftp.postgresql.org/pub/source/v8.4.2/postgresql-8.4.2.tar.gz

最好下载在 / 根目录下

tar -zxvf  postgresql-8.4.2.tar.gz 解压缩

（2）下载Bandwidthd

wget http://nchc.dl.sourceforge.net/project/bandwidthd/bandwidthd/bandwidthd%202.0.1/bandwidthd-2.0.1.tgz

tar -zxvf bandwidthd-2.0.1.tgz

（3）安装编译需要的软件包

    编译Postgresql需要

    yum install gcc cpp glibc glibc-devel gcc-c++ make

    编译Bandwidthd需要

    yum install libpcap libpcap-devel libpng libpng-devel gd gd-devel

（4）进入postgres目录，开始编译postgres

     ./configure

     执行后，看看有没有错误

然后执行gmake

rm -rf ./testtablespace
mkdir ./testtablespace

gmake[1]: Leaving directory `/postgresql-8.4.2/src'
gmake -C config all

gmake[1]: Nothing to be done for `all'.
gmake[1]: Leaving directory `/postgresql-8.4.2/config'
All of PostgreSQL successfully made. Ready to install.

看到ready to instal 基本就成功了

等编译完成后，没有错误，再执行 gmake install

详细说明，可以看

（5）编译Bandwidthd

      在编译Bandwithd前，请检查 /usr/local/pgsql/ 下是否已经有 bandwidthd需要的库和头文件了。

      进入bandwidthd目录

      ./configure

      执行configure后，看看是否有错误。注意，如果Postgresq编译有问题化，Bandwidthd编译出来的程序是不会支持Postgresql的。

      make

      可以通过程序文件大小判断

     如果不带Postgresq支持的是11xxxx 的大小。

这2个地方必须是yes，才能编译出支持Postgrsql的程序.

make install后，程序的配置文件在 /usr/local/bandwidthd/etc 目录

二、如果要能成功运行Bandwidthd，还需要创建数据库

在Bandwidthd目录下，有个schema.postgresql脚本，要首先将他导入数据库

su - postgres
psql
create database bandwidthd;
[postgres@bwd bandwidthd-2.0.1]$ psql bandwidthd postgres< schema.postgresql
CREATE TABLE
CREATE INDEX
CREATE INDEX
CREATE TABLE
CREATE INDEX
CREATE INDEX
CREATE TABLE
CREATE INDEX
CREATE TABLE
CREATE INDEX
NOTICE:  CREATE TABLE will create implicit sequence "sensors_sensor_id_seq"for serial column "sensors.sensor_id"
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "sensors_pkey"for table "sensors"
CREATE TABLE
[postgres@bwd bandwidthd-2.0.1]$

重启bandwidthd 后postgresql数据库，2分钟后，数据库里就有数据了。
