　　Linux使用FlowScan完全安装配置指南
　　2015.04.30
　　

　　1. Flowscan介绍
　　

　　Flowscan采用Perl语言编写，主要用于处理展现网络设备发过来Netflow数据。
　　

　　早先Flowscan利用cflow收集处理netflow v5数据，后来利用flow-tool收集处理netflow v5数据，
　　注意cflow需要在flow-tool下面编译供flowscan后期使用，然后flowscan对流进行扫描分析并绘图，
　　是一款挺不错的Netflow分析展现工具。
　　

　　CUFlow是Flowscan一个扩展模块，比Flowscan自带的CampusIO和SubNetIO两个模块友好，因此
　　这里采用CUFlow模块替代自带的模块。
　　

　　

　　2. 检查或安装依赖软件
　　

　　2.1. 检查Apache配置
　　Suse11:~ # apache2ctl -v
　　Server version: Apache/2.2.12 (Linux/SUSE)
　　Server built:   Mar 27 2013 18:47:49
　　Suse11:~ # grep -v \^# /etc/sysconfig/apache2
　　

　　DOC_SERVER="no"
　　APACHE_CONF_INCLUDE_FILES=""
　　APACHE_CONF_INCLUDE_DIRS=""
　　

　　APACHE_MODULES="actions alias auth_basic authn_file authz_host authz_groupfile authz_default authz_user authn_dbm autoindex cgi dir env expires include log_config mime negotiation setenvif suexec userdir php5 reqtimeout"
　　

　　APACHE_SERVER_FLAGS=""
　　APACHE_HTTPD_CONF=""
　　APACHE_MPM=""
　　APACHE_SERVERADMIN=""
　　APACHE_SERVERNAME=""
　　APACHE_START_TIMEOUT="2"
　　APACHE_SERVERSIGNATURE="on"
　　APACHE_LOGLEVEL="debug"
　　APACHE_ACCESS_LOG="/dev/null combined"
　　APACHE_USE_CANONICAL_NAME="off"
　　APACHE_SERVERTOKENS="OS"
　　APACHE_EXTENDED_STATUS="off"
　　APACHE_DISABLE_SSL_COMPRESSION="on"
　　Suse11:~ #
　　

　　2.2. 检查Perl5安装
　　Suse11:~ # perl -v
　　

　　This is perl, v5.10.0 built for x86_64-linux-thread-multi

　　Suse11:~ #
　　

　　2.3. 编译安装RRDTool
　　

　　# tar xvzf rrdtool-1.4.5.tar.tar
　　# cd rrdtool-1.4.5
　　修改configure,找到
　　PERL_MAKE_OPTIONS="PREFIX=$langpref INSTALL_BASE= LIB=$langpref/lib/perl/$PERL_VERSION"
　　修改为
　　PERL_MAKE_OPTIONS="PREFIX=$langpref INSTALL_BASE= LIB=$langpref/lib/perl5/$PERL_VERSION"
　　#./configure --prefix=/usr --sysconfdir=/etc --enable-shared
　　# make
　　# make install
　　或者make install site-perl-install
　　

　　Suse11:~ # rrdtool -v

　　2.4. 编译安装flow-tools
　　

　　2.4.1 下载flow-tools-0.68.5.1.tar.bz2
　　tar -xvjf flow-tools-0.68.5.1.tar.bz2
　　cd flow-tools-0.68.5.1
　　./configure --prefix=/usr --sysconfdir=/etc
　　make
　　make install
　　

　　2.4.2 flow-tool的自启动脚本，于Cacti的flowview插件合用
　　Suse11:~ # cat /etc/init.d/flow-capture
　　#!/usr/bin/php
　　<?php
　　/*
　　# description: Start Flow-Capture
　　# chkconfig: 2345 95 00

　　$cacti_base = '/srv/www/htdocs/cacti';
　　

　　include_once($cacti_base . '/include/global.php');
　　$tools_path = read_config_option("path_flowtools");
　　

　　if (isset($_SERVER['argv'][1])) {
　　switch (strtolower($_SERVER['argv'][1])) {
　　case 'start':
　　start();
　　break;
　　case 'stop':
　　stop();
　　break;
　　case 'restart':
　　restart();
　　break;
　　default:
　　echo "Usage: /etc/init.d/flow-capture {start|stop|restart}\n";
　　break;
　　}
　　}
　　

　　function start() {
　　global $tools_path, $cacti_base;;
　　

　　echo "NOTE: Starting Flow Tools\n";
　　$devices = db_fetch_assoc("SELECT * FROM plugin_flowview_devices");
　　if (!empty($devices)) {
　　$path = db_fetch_cell("SELECT value FROM `settings` WHERE name = 'path_flows_dir'");
　　if ($path == '')
　　break;
　　if (substr($path, -1) == '/') {
　　$path = substr($path, 0, -1);
　　}
　　foreach ($devices as $device) {
　　$port   = $device['port'];
　　$folder = $device['folder'];
　　$nest   = $device['nesting'];
　　$v      = $device['version'];
　　$from   = $device['allowfrom'];
　　$comp   = $device['compression'];
　　$rotate = $device['rotation'];
　　$expire = $device['expire'] * ($rotate + 1);
　　if (!is_dir("$path/$folder")) {
　　echo "NOTE: Making directory '$path/$folder'\n";
　　mkdir("$path/$folder");
　　}
　　if (is_dir("$path/$folder")) {
　　echo "NOTE: Launching flow-capture as '$tools_path/flow-capture -w $path/$folder 0/$from/$port -S5 -V$v -z $comp -n $rotate -e $expire -N $nest'\n";
　　shell_exec($tools_path . "/flow-capture -w $path/$folder 0/$from/$port -S5 -V$v -z $comp -n $rotate -e $expire -N $nest");
　　}
　　}
　　}else{
　　echo "WARNING: No flows configured\n";
　　}
　　}
　　

　　function stop() {
　　global $tools_path, $cacti_base;;
　　

　　echo "NOTE: Stopping Flow Tools\n";
　　$devices = db_fetch_assoc("SELECT * FROM plugin_flowview_devices");
　　if (!empty($devices)) {
　　shell_exec('killall -9 ' . $tools_path . '/flow-capture');
　　}
　　}
　　

　　function restart() {
　　stop();
　　start();
　　}
　　Suse11:~ #
　　

　　2.4.3. 启动flow-capture
　　Suse11:~ # /etc/init.d/flow-capture start
　　NOTE: Starting Flow Tools
　　NOTE: Launching flow-capture as '/usr/bin/flow-capture -w /var/netflow/cisco3745 0/0/2055 -S5 -V5 -z 0 -n 1439 -e 525600 -N -1'
　　Suse11:~ # ps -eaf |grep flow-capture |grep -v grep
　　root      7087     1  4 20:32 ?        00:00:00 /usr/bin/flow-capture -w /var/netflow/cisco3745 0/0/2055 -S5 -V5 -z 0 -n 1439 -e 525600 -N -1

　　2.5. 安装flowscan需要的Perl模块
　　Perl Modules- In addition to Perl5, you will need the modules listed below.
　　Net::Patricia
　　Boulder::Stream
　　HTML::Table
　　ConfigReader::DirectiveStyle
　　Cflow
　　

　　从http://search.cpan.org/找到并下载这些包
　　# perl Makefile.PL
　　# make
　　# make install
　　

　　对于ConfigReader, 解压缩到/usr/lib/perl5/site_perl/5.10.0目录即可
　　Suse11:~/bin/flow-tools-0.68.5.1 # ls -al /usr/lib/perl5/site_perl/5.10.0/ConfigReader
　　total 76
　　drwxr-xr-x 2  405    4  4096 Feb 20  1996 .
　　drwxr-xr-x 9 root root  4096 Apr 30 11:09 ..
　　-rw-r--r-- 1  405    4 25265 Feb 17  1996 COPYING.LIB
　　-rw-r--r-- 1  405    4  2424 Feb 14  1996 ConfigReader.pod
　　-rw-r--r-- 1  405    4  9084 Feb 20  1996 DirectiveStyle.pm
　　-rw-r--r-- 1  405    4  2152 Feb 19  1996 README

　　-rw-r--r-- 1  405    4  7573 Feb 20  1996 Values.pm
　　Suse11:~/bin/flow-tools-0.68.5.1 #
　　

　　注意，CFlow需要在flow-tools的环境下编译，因此该步骤需要在flow-tool编译完成后进行。
　　cd flow-tools-0.68.5.1
　　cd contrib
　　tar -zxvf Cflow-1.053.tar.gz
　　cd Cflow-1.051
　　perl Makefile.PL
　　make
　　make install
