CentOS5环境下实战Linux开源流量监控软件Bandwidthd

 

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 

       vi graph.c
 Top20修改为Top100 (有4个)#100表示检测的ip数量#

Counter < 21修改为Counter < 101 (有两个)

7.安�bbandwidthd

     cd /usr/local/src/bandwidthd-2.0.1

     ./configure
    make install

8.修改bandwidthd配置文件

     vi /usr/local/bandwidthd/etc/bandwidthd.conf

  ####################################################

1. Bandwidthd.conf
2.  
3. Commented out options are here to provide
4. documentation and represent defaults

1. Subnets to collect statistics on. Traffic that
2. matches none of these subnets will be ignored.
3. 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

1. Device to listen on
2. Bandwidthd listens on the first device it detects
3. by default. Run "bandwidthd -l" for a list of
4. 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)

###################################################

1. Options that don't usually get changed

1. An interval is 2.5 minutes, this is how many
2. intervals to skip before doing a graphing run
   skip_intervals 1 #默认2.5 minutes 刷新

1. Graph cutoff is how many k must be transfered by an
2. 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
      启动bandwidthd
      cd /usr/local/bandwidthd 
     ./bandwidthd

 
10.设定开机自动启动 bandwidthd

     vi /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

    http://IP/bandwidthd

   安装碰到的问题1、bandwidthd编译出会出现：configure: error: Bandwidthd requires but cannot find libpcap

  解决办法：http://www.tcpdump.org/release/下载http://www.tcpdump.org/release/libpcap-1.1.1.tar.gz

     tar zxvf libpcap-1.1.1.tar.gz
     cd libpcap-1.1.1
    ./configure --prefix=/usr/
    make && make install

   更新libpcap-devel
   yum install libpcap-devel

  启动bandwidthd出错
  [root@localhost bandwidthd]# ./bandwidthd 
  ./bandwidthd: error while loading shared libraries: libpcap.so.1: cannot open shared object    file: No such file or directory

  解决办法
  [root@localhost bandwidthd]# cd /usr/local/lib/
  [root@localhost lib]# cp libpcap.so.1 /usr/lib
  [root@localhost lib]#ldconfig

大家可以试下。

提示：如果如上Top100 只表示检测这个网段中的ip个IP，但是在页面却不会现实100个IP的状况，默认在图形节目显示20个IP

        那么如果想显示更多的IP的状态，只要在刚刚的配置文件中搜索top20 修改为n（n，表示你需要显示的IP数量），修改好后，需要重新编译安装这个软件Bandwidthd
