Linux下MRTG搭建
linux下MRTG搭建
還需要有apache的支持,本次試驗apache安裝在/usr/local/apache下
所需軟件安裝包如下，均為源代碼安裝包
gd-2.0.33.tar.gz
zlib-1.2.3.tar.gz
libpng-1.2.15.tar.gz
jpegsrc.v6b.tar.gz
freetype-2.1.9.tar.gz
fontconfig-2.3.2.tar.gz
mrtg-2.13.2.tar.gz
一、安裝在MRTG所需的組件
2、安裝zlib庫
tar -xvf zlib-1.2.3.tar.gz
cd zlib-1.2.3
- ./configure
- make
- make install
3.安裝libpng庫
tar -zxvf libpng-1.2.15.tar.gz
cd libpng-1.2.15
- ./configure
- make
- make install
4、安裝JPEG庫
tar -zxvf jpegsrc.v6b.tar.gz
cd jpeg-6b
- ./configure --enable-static --enable-shared
- make
- make install
5、安裝安裝Freetype
tar -zxvf freetype-2.1.9.tar.gz
cd freetype-2.1.9
- ./configure
- make
- make install
6、安裝Fontconfig(freetype-devel fontconfig-devel )
tar -zxvf fontconfig-2.3.2.tar.gz
cd fontconfig-2.3.2.tar.gz
- ./configure
- make
- make install
7、編譯GD庫
安裝GD庫
安裝命令如下
tar -zxvf gd-2.0.33.tar.gz
- cd gd-2.0.33
- ./configure
如果在輸出信息中如下
- Support for PNG library: no
- Support for JPEG library: no
- Support for Freetype 2.x library: no
- Support for Fontconfig library: no
- Support for Xpm library: no
- Support for pthreads: yes
如果全部都顯示的為yes，我們就可以直接去裝MRTG了，此次環境中只有 一項顯示為yes,所以還要安裝其組件
- make
- make install
二、安裝mrtg
tar -zxvf mrtg-2.13.2.tar.gz
cd mrtg-2.13.2
- ./configure --prefix=/usr/local/mrtg --with-gd=/usr/include --with-gd-lib=/usr/lib --with-gd-inc=/usr/include --with-png=/usr/include --with-png-lib=/usr/lib --with-zlib=/usr/include --with-zlib-lib=/usr/lib
- make
- make install
三、調整參數，對端口進行流量監控
1、 生成mrtg.cfg文件，用于存放mrtg配置信息
- /usr/local/mrtg/bin/cfgmaker --output /usr/local/apache/htdocs/mrtg.cfg public@121.52.209.160 (public為SNMP團體名稱，ip為被監控的設備。)
2、修改mrtg.cfg文件參數
- vi /usr/local/apache/htdocs/mrtg.cfg
把#去掉 把Workdir后的路徑改成/usr/local/apache/htdocs ：指定mrtg的工作目錄
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/apache/htdocs/mrtg.cfg ：多執行幾遍，直到不出現信息
4、生成頁面文件
- /usr/local/mrtg/bin/indexmaker --output /usr/local/apache/htdocs/index.html --title=ruishengIDC /usr/local/apache/htdocs/mrtg.cfg(中間的參數可以省略)
5、讓數據自動刷新
crontab -e
然后寫入
- */5 * * * * env LANG=C /usr/local/mrtg/bin/mrtg /usr/local/apache/htdocs/mrtg.cfg
(注：如之前未加env LANG=C的話，則這里也不用加),意思為讓系統在后臺每五分鐘執行一次env LANG=C /usr/local/mrtg/bin/mrtg /usr/local/apache/htdocs/mrtg.cfg
