linux~MRTG监控相关配置

一、安装GD库

1、安装libpng

#tar xvf libpng-1.2.10.tar.tar

#cd libpng-1.2.10

#./configure  --prefix=/usr/local/png

#make;make install

#ln -s /usr/local/png/lib/* /usr/lib/

 

2、安装jpeg

#mkdir /usr/local/jpeg

#mkdir /usr/local/jpeg/bin

#mkdir /usr/local/jpeg/lib

#mkdir /usr/local/jpeg/include

#mkdir /usr/local/jpeg/man

#mkdir /usr/local/jpeg/man/man1

#tar xvf jpegsrc.v7.tar.tar

#cd jpeg-7

#./configure --prefix=/usr/local/jpeg --enable-shared --enable-static

#make;make install

#ln -s /usr/local/jpeg/lib/* /usr/lib/

 

3、安装 freetype

#tar xvf freetype-2.3.9.tar.tar

#cd freetype-2.3.9

#./configure --prefix=/usr/local/freetype

#make;make install

 

4、安装fontconfig

#tar zxvf fontconfig-2.4.2.tar.gz

#cd fontconfig-2.4.2

#./configure        --prefix=/usr/local/fontconfig --with-freetype-config=/usr/local/freetype/bin/freetype-config

#make;make install

 

5、安装GD

#tar zxvf gd-2.0.32.tar.gz

#cd gd-2.0.32

#./configure --prefix=/usr/local/gd --with-png=/usr/local/png --with-jpeg=/usr/local/jpeg --with- freetype=/usr/local/freetype --with-fontconfig=/usr/local/fontconfig

 

** Configuration summary for gd 2.0.32:**

   Support for PNG library:          yes

   Support for JPEG library:         yes

   Support for Freetype 2.x library:    yes

   Support for Fontconfig library:     yes

   Support for Xpm library:          no

   Support for pthreads:             yes

 

#cp /usr/local/png/include/png.h ./

#cp /usr/local/png/include/pngconf.h ./

#make;make install

 

6、安装zlib-1.2.3.tar.gz

tar zxvf zlib-1.2.3.tar.gz

cd zlib-1.2.3

./configure --prefix=/usr/local/zlib

make && make install

 

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

安装Apache

./configure --prefix=/usr/local/apache --enable-modules=most --enable-proxy --enable-proxy-ajp --enable-ssl

make && make install

 

二、安装MRTG

   tar -zxvf mrtg-2.13.2.tar.gz

   cd mrtg-2.13.2

  　./configure --prefix=/usr/local/mrtg --with-gd=/usr/local/gd --with-gd-lib=/usr/local/gd/lib --with-gd-inc=/usr/local/gd/include --with-png=/usr/local/png --with-png-lib=/usr/local/png/lib --with-zlib=/usr/local/zlib --with-zlib-lib=/usr/local/zlib/lib

　　make

　　make install

 

三、调整参数，对端口进行流量监控

1、 生成mrtg.cfg文件，用于存放mrtg配置信息

#mkdir /usr/local/mrtg/etc

#/usr/local/mrtg/bin/cfgmaker --output /usr/local/mrtg/etc/mrtg.cfg public@121.52.209.160

 

2、修改mrtg.cfg文件参数

#mkdir /usr/local/apache/htdocs/mrtg

#vi /usr/local/mrtg/etc/mrtg.cfg

     把Workdir后的路径改成/usr/local/apache/htdocs/mrtg   ：指定mrtg的工作目录

     把#Options[_]: growright, bits  ：前面的#去掉

     在加入一行Language:Chinese ：使mrtg支持中文

 

3、env LANG=C /usr/local/mrtg/bin/mrtg /usr/local/mrtg/etc/mrtg.cfg   ：多执行几遍，直到不出现信息

然后显示的信息如下

/usr/local/mrtg/bin/rateup Can't remove 121.52.209.160_4227866.old updating log file

 

4、生成页面文件

# /usr/local/mrtg/bin/indexmaker --output /usr/local/apache/htdocs/mrtg/index.html --title=ruishengIDC --sort=title --sort=name --sort=descr --sort=original /usr/local/mrtg/etc/mrtg.cfg

 

 

5、让数据自动刷新

  crontab -e

然后写入*/5 * * * * env LANG=C /usr/local/mrtg/bin/mrtg /usr/local/mrtg/etc/mrtg.cfg

 

service crond restart

service httpd restart

service snmpd restart
