Linux伺服器---流量監控MRTG

MRTG

       MRTG可以分析網絡流量，但是它必須依賴SNMP協定。将收集到的資料生成HTML檔案，以圖檔的形式展示出來

1、安裝一些依賴軟體

​ ​[root@localhost bandwidthd-2.0.1]# yum install -y net-snmp​ ​

2、配置snmp，編輯配置檔案“/etc/snmp/snmpd.conf”

​ ​[root@localhost bandwidthd]# gedit /etc/snmp/snmpd.conf​ ​ ​ ​view    systemview    included  .1.3.6.1.2.1.1​ ​ ​ ​view    systemview    included  .1.3.6.1.2.1.25.1.1​ ​ ​ ​view    systemview    included  .1.3.6.1.2.1.2​ ​

3、啟動snmp服務

​ ​[root@localhost bandwidthd]# service snmpd start​ ​ ​ ​正在啟動​ ​​ ​snmpd​ ​​ ​：​ ​​ ​                                           [​ ​​ ​确定​ ​​ ​]​ ​ ​ ​[root@localhost bandwidthd]#​ ​

4、下載下傳bandwidthd軟體（​​https://oss.oetiker.ch/mrtg/pub/?M=D​​），或者以yum方式線上安裝

​ ​[root@localhost bandwidthd]# yum install -y mrtg​ ​

5、修改配置檔案”/etc/httpd/conf.d/mrtg.conf”

​ ​[root@localhost bandwidthd]# gedit /etc/httpd/conf.d/mrtg.conf ​ ​ ​ ​<Location /mrtg>​ ​ ​ ​    Order deny,allow​ ​ ​ ​#    Deny from all      //​ ​​ ​這句要注釋掉​ ​ ​ ​    Allow from all      //​ ​​ ​這裡為​ ​​ ​all​ ​​ ​，允許檢測所有​ ​​ ​ip​ ​ ​ ​    Allow from ::1​ ​ ​ ​    # Allow from .example.com​ ​ ​ ​</Location>​ ​

6、生成mrtg檔案，并做一些修改。

​ ​[root@localhost bandwidthd]# cfgmaker [email protected]>/etc/mrtg/mrtg.cfg       //​ ​​ ​生成檔案，注意​ ​​ ​ip​ ​​ ​位址需要使用者自己設定​ ​ ​ ​[root@localhost bandwidthd]# gedit /etc/mrtg/mrtg.cfg      //​ ​​ ​修改檔案​ ​ ​ ​#  for UNIX​ ​ ​ ​ WorkDir: /var/www/mrtg      //​ ​​ ​目前處于​ ​​ ​centos​ ​​ ​系統，是以這句去掉注釋​ ​​ ​.​ ​​ ​這個路徑是​ ​​ ​apache​ ​​ ​下的網頁路徑​ ​ ​ ​#  or for NT​ ​ ​ ​# WorkDir: c:\mrtgdata​ ​ ​ ​### Global Defaults​ ​ ​ ​#  to get bits instead of bytes and graphs growing to the right​ ​ ​ ​ Options[_]: growright, bits    //​ ​​ ​去掉注釋​ ​

7、生成html檔案，執行三次指令

​ ​[root@localhost bandwidthd]# env LANG=C mrtg /etc/mrtg/mrtg.cfg   //​ ​​ ​第一次​ ​ ​ ​2018-08-22 14:50:00, Rateup WARNING: /usr/bin/rateup could not read the primary log file for 192.168.0.113_2​ ​ ​ ​2018-08-22 14:50:00, Rateup WARNING: /usr/bin/rateup The backup log file for 192.168.0.113_2 was invalid as well​ ​ ​ ​2018-08-22 14:50:00, Rateup WARNING: /usr/bin/rateup Can't remove 192.168.0.113_2.old updating log file​ ​ ​ ​2018-08-22 14:50:00, Rateup WARNING: /usr/bin/rateup Can't rename 192.168.0.113_2.log to 192.168.0.113_2.old updating log file​ ​ ​ ​[root@localhost bandwidthd]# env LANG=C mrtg /etc/mrtg/mrtg.cfg    //​ ​​ ​第二次​ ​ ​ ​[root@localhost bandwidthd]# env LANG=C mrtg /etc/mrtg/mrtg.cfg    //​ ​​ ​第三次​ ​

8、在浏覽器輸入“127.0.0.1/mrtg/192.168.0.113_2.html”,這樣就可以通路了
