自己做了一周，感觉久了一点啊。带着胜利的喜悦，来这里与大家分享。有不足的地方请大家多多原谅。
以下是我的安装手稿：
Mrtg+rrdtool+routers2.cgi
1.技术说明：
mrtg 是一个监控网络链路流量负载的工具软件，它通过snmp协议从设备得到设备的流量信息。然后将采样数据保存到rrd数据库中。Rrd 这个工具专门用于收集数据, 并且按照一定的周期生成曲线图 ,不过它不包含数据采集功能, 而且灵活性高适应面更广.
2.所需软件：
Perl Zlib Gd libpng Apache snmp mrtg(我的系统是linux AS4 ,一般的都是默认安装的).可以用 Rpm –qa|grep *** 这个命令来查看是否安装。
Rrdtool 下载地址: http://people.ee.ethz.ch/~oetiker/w...l- 1.0.48.tar.gz
Routers2.cgi 下载地址: http://www.steveshipway.org/softwar...s2-v2.14.tar.gz
3. 安装步骤：
1). Mrtg 的安装
Mrtg 系统没有默认安装，找到linux as4 第二张光盘，找到一个mrtg-2.10.15-1.i386.rpm包，然后rpm –ivh mrtg-2.10.15-1.i386.rpm就可以安装使用了.
2). Rrdtool的安装
Cd /home
Mkdir mrtg
Cd mrtg
Tar zvf rrdtool-1.2.11.tar.tar
Cd rrdtool-1.2.11
./configure –disable-tcl 注意: rrdtool不需要tcl的支持，如果不关闭加载tcl可能会出现问题
Make
Make install
4. 配置snmp :
1) 以cisco 2950T为例，作为mrtg 的客户端。
C:\telnet 您的交换机的IP
User Access Verification
Password:
TNKSW>en Password:
TNKSW# conf t TNKSW(config)# nmp-server community abc RO 设置密码：abc
TNKSW(config)# snmp-server trap-source FastEthernet0/1监控对象端口: FastEthernet0/1
TNKSW(config)# snmp-server contact abc@163.com 管理标识abc@163.com
TNKSW(config)# snmp-server host 192.168.0.6 abc 来源mrtg地址：192.168.0.6
TNKSW(config)# snmp-server enable traps 要监控的内容 traps TNKSW# sh run
TNKSW# wr
2) 配置mrtg服务端
首先编写一个自动生成监控对象参数的脚本automr.sh：
#!/bin/sh
cfgmaker --global "WorkDir: /opt/sino/web/mrtg" \ //存放库文件的地方
--global "Options[_]: growright,bits" \
--ifref=ip \
--output mrtg.test \ //输出mrtg.test文件
abc@ip # a bc 是你snmp认证的口令，ip交换机的IP
保存automr.sh 文件。
Chmod 775 automr.sh
Sh automr.sh
这样,mrgt就采集到了被监控设备的信息了。下一步需要初始化rrdtool
Vi mrtg.test
在 Options[_]: growright,bits 下面添加如下语句：
LogFormat: rrdtool //用rrdtool初始化
PathAdd:/usr/bin
LibAdd:/usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/ //perl安装的路径。
Mkdir /home/mrtg/etc
Cp mrtg.test /home/mrtg/etc/switch.cfg
到这里，snmp 和mrtg都配置完毕，下一步生成 rrd 数据库了。
/usr/bin/mrtg /home/etc/switch.cfg
执行完毕以后，就会在 /home/mrtg/etc目录下生成一个swtich.ok 文件。
5.安装routers.cgi：
Cd /home/mrtg
Tar zvf routers2-v2.14.tar.tar
Cd routers-2.2.14
./configure --prefix=/usr/local
Make; make install
Perl install.pl
# NOTICE: This module requires libgd 2.0.5 or higher.
it will NOT work with earlier versions.
For earlier versions of libgd, use GD version 1.41.
Where is libgd installed? [/usr/lib] /usr/local/gd/lib
Please choose the features that match how libgd was built:
Build JPEG support? [y] y //需要输入的地方
Build FreeType support? [y] n //需要输入的地方
Build XPM support? [y] n //需要输入的地方
If you experience compile problems, please check the @INC, @LIBPATH and @LIBS
arrays defined in Makefile.PL and manually adjust, if necessary.
Writing Makefile for GD
# make;make install
# tar zxvf routers2-v2.11.tar.Z
# cd routers2-v2.11
# perl install.pl //执行该命令后会要你回答一系列的问题,请根据你的系统情况如实填写
This program attempts to install the routers2.cgi package, located in
the current directory. It will attempt to identify system settings,
but you must confirm the locations guessed, or give the correct
information.
At any point, you can answer 'quit' to abort the installation.
Depending on your Perl implementation, you may also have line editing
and history capability.
Default answers are in square brackets before the prompt.
Continue [yes]?
Checking Perl libraries...
RRDs library found correctly.
WARNING: You do not have the GD Perl libraries installed correctly.
routers2.cgi will still run, but the Compact Summary display will not work.
Download the GD libraries from CPAN.org if required.
NT Users should use PPM to collect GD from ActiveState.
UNIX users should note that they need the GD.pm Perl library IN ADDITION to
the libgd.a C library.
Continue [y]?
WARNING: You do not have the Time::Zone library installed.
This is not a big problem, so don't worry.
This will only be a potential problem if you are using multiple time zones and
your operating system does not support the TZ environment variable.
If you wish to obtain this package, visit CPAN.org
WARNING: You do not have the Net::SNMP library installed.
This library is required if you wish to use the routingtable extension.
routers2.cgi will run correctly without this package, however.
If you wish to obtain this package, visit CPAN.org
FINDING OUT ABOUT YOUR SYSTEM
0. Attempting to identify your OS and web server...
- I think you are running under UNIX.
- I think you have Apache installed in
/etc/httpd/conf //apache安装的地方
1. Web server document root directory.
This is the base document directory of your web server.
Document root [/var/www/html]? //网站主目录
2. Web server CGI directory.
This is the directory where your web server keeps the CGI scripts.
CGI directory [/var/www/cgi-bin/]? //网站cgi目录
3. MRTG install directory.
This is the directory where your MRTG configuration files are kept
MRTG config directory? /etc/mrtg //你的mrtg的配置文件存放地
4. MRTG config files.
This is the wildcarded filename format for your MRTG configuration files.
Use a '*' to mean 'any characters' - for example, '*.cfg' or '*/*.conf'.
MRTG files [*.cfg]? //mrtg配置文件的格式（后缀）
5. RRD Database directory.
This is the directory where your .rrd files are kept
RRD directory [/var/www/html/mrtg/]? //存放rrd库的地方，在你的mrtg配置文件里设的
6. Perl executable.
This is the full pathname of where the Perl executable file is kept.
Perl executable [/usr/bin/perl]? //默认
7. routers2.cgi configuration file
This is the file that will hold the routers2.cgi configuration. Unless you
have a reason to move it, stick with the default.
If this file already exists, I will ask before overwriting it!
Configuration file [/var/www/html/mrtg/routers2.conf]? /var/www/html/mrtg/routers2.conf
//你的外挂脚本配置文件存放位置
ASKING OPTIONS
1. Net::SNMP does not appear to be installed. Extensions disabled.
If you subsequently install Net::SNMP, then you can enable the extensions
in the routers2.conf file.
2. GD does not appear to be installed. This is required for the compact
summary screen to work. If you intend to install it later, answer YES.
Otherwise, answer NO.
Activeate Compact Summary screen [no]? yes //需要GD
3. How big should 1K and 1M be? This is the 'usebigk' parameter from the
routers2.conf file. You have three options - 'yes', 'no' and 'mixed'.
yes -> 1K=1024, 1M=1024x1024
no -> 1K=1000, 1M=1000x1000
mixed -> 1K=1024, 1M=1024x1000 (dont ask)
'usebigk' option [mixed]? yes //选择流量计算方法
4. Can I attempt to send an email to the author to let him know that the
software has been installed? This will only give your routers.cgi version,
Perl version, and Operating System version.
Can I mail [yes]?
INSTALLING SOFTWARE
Perl is : /usr/bin/perl
MRTG files : /etc/mrtg/*.cfg
RRD files : /var/www/html/mrtg/
Doc root : /var/www/html
CGI bin : /var/www/cgi-bin/
Config file : /var/www/html/mrtg/routers2.conf
Extensions : INACTIVE
Compact page: ENABLED
'usebigk' : yes
Mail Steve : yes
Other options can be set later by modifying the Config file
Continue [yes]?
WARNING: /var/www/html/mrtg/routers2.conf already exists!
Overwrite existing file [no]? yes
Creating /var/www/html/mrtg/routers2.conf...
No Mail::Send available, trying sendmail instead.
/usr/sbin/sendmail: invalid option -- U
/usr/sbin/sendmail returned code 0. Looks like I cant send an email after all.
** ALL COMPLETE **
You should now be able to run the software, although you may need to
make sure you have your web server running.
To access the frontend, point your favourite web browser at the URL:
http://netcool2/cgi-bin/routers2.cgi
See http://www.cheshire.demon.co.uk/pub/wishlist for information on
how to say 'thanks' for this free software.
* Apache users should make sure that mod_expires is loaded and enabled
* Apache should also be configured with 'AllowOverride: All' for the directory
/var/www/html/graphs
* Apache users should NOT use mod_perl or speedycgi for this script.
* You may wish to tighten the rights granted on the graphs directory
/var/www/html/graphs //图片输出位置
这样你就可以通过 http://ip/cgi-bin/routers2.cgi来查看你的流量图了。 |
