标题:CentOS5环境下实战Linux开源流量监控软件Bandwidthd
内容:
1.基本编译组件安装
yum install gcc cpp glibc glibc-devel gcc-c++
2. PCAP/PNG/GD Library（图像处理库）
yum install libpcap libpng libpng-devel gd gd-devel
3.安装apache2
yum install httpd mod_ssl
chkconfig httpd on
service httpd start
4.下载bandwidthd
wget http://voxel.dl.sourceforge.net/project/bandwidthd/bandwidthd/bandwidthd%202.0.1/bandwidthd-2.0.1.tgz
5.解压缩bandwidthd
tar -xzvf bandwidthd-2.0.1.tgz
6.修改bandwidthd统计上限(预设为20,修改为100)
cd /usr/local/src/bandwidthd-2.0.1
vim graph.c
Top20修改为Top100 (有三个)
Counter < 21修改为Counter < 101 (有两个)
7.安裝bandwidthd
cd /usr/local/src/bandwidthd-2.0.1
./configure
make install
8.修改bandwidthd配置文件
vim /usr/local/bandwidthd/etc/bandwidthd.conf
####################################################
# Bandwidthd.conf
#
# Commented out options are here to provide
# documentation and represent defaults
# Subnets to collect statistics on. Traffic that
# matches none of these subnets will be ignored.
# Syntax is either IP Subnet Mask or CIDR
#subnet 10.0.0.0 255.0.0.0
#subnet 192.168.0.0/16
#subnet 172.16.0.0/12
subnet 184.82.43.0/24 #需要监控的网段
# Device to listen on
# Bandwidthd listens on the first device it detects
# by default. Run "bandwidthd -l" for a list of
# devices.
dev "any" #(这是你要检测的网卡,可以调整为对应的网络连接设备)
###################################################
# Options that don't usually get changed
# An interval is 2.5 minutes, this is how many
# intervals to skip before doing a graphing run
skip_intervals 1 #默认2.5 minutes 刷新
# Graph cutoff is how many k must be transfered by an
# ip before we bother to graph it
graph_cutoff 1024 #默认1M 以上的流量才有图形
#Put interface in promiscuous mode to score to traffic
#that may not be routing through the host machine.
promiscuous true #设置网卡在混杂模式中记录
#Log data to cdf file htdocs/log.cdf
output_cdf true #在bandwidthd目录中生成log2.cdf 以log.cdf格式数据记录
#Read back the cdf file on startup
recover_cdf true #在启动bandwidth时重新读取cdf的数据
#Libpcap format filter string used to control what bandwidthd see's
#Please always include "ip" in the string to avoid strange problems
filter "ip" #以ip为过滤对象
#Draw Graphs – This default to true to graph the traffic bandwidthd is recording
#Usually set this to false if you only want cdf output or
#you are using the database output option. Bandwidthd will use very little
#ram and cpu if this is set to false.
graph true #图形生成
#Set META REFRESH seconds (default 150, use 0 to disable).
meta_refresh 150 #网页刷新时间
9.建立 Apache 到 bandwidthd 软连接
cd /var/www/html
ln -s /usr/local/bandwidthd/htdocs bandwidthd
10.设定开机自动启动 bandwidthd
vim /etc/rc.local
加入/usr/local/bandwidthd/bandwidthd
11.过几分钟，就可以浏览bandwidthd 生成的图形报表了
