Linux服务器---流量监控MRTG

MRTG

       MRTG可以分析网络流量，但是它必须依赖SNMP协议。将收集到的数据生成HTML文件，以图片的形式展示出来

1、安装一些依赖软件

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

2、配置snmp，编辑配置文件“/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、启动snmp服务

​ ​[root@localhost bandwidthd]# service snmpd start​ ​ ​ ​正在启动​ ​​ ​snmpd​ ​​ ​：​ ​​ ​                                           [​ ​​ ​确定​ ​​ ​]​ ​ ​ ​[root@localhost bandwidthd]#​ ​

4、下载bandwidthd软件（​​https://oss.oetiker.ch/mrtg/pub/?M=D​​），或者以yum方式在线安装

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

5、修改配置文件”/etc/httpd/conf.d/mrtg.conf”

​ ​[root@localhost bandwidthd]# gedit /etc/httpd/conf.d/mrtg.conf ​ ​ ​ ​<Location /mrtg>​ ​ ​ ​    Order deny,allow​ ​ ​ ​#    Deny from all      //​ ​​ ​这句要注释掉​ ​ ​ ​    Allow from all      //​ ​​ ​这里为​ ​​ ​all​ ​​ ​，允许检测所有​ ​​ ​ip​ ​ ​ ​    Allow from ::1​ ​ ​ ​    # Allow from .example.com​ ​ ​ ​</Location>​ ​

6、生成mrtg文件，并做一些修改。

​ ​[root@localhost bandwidthd]# cfgmaker [email protected]>/etc/mrtg/mrtg.cfg       //​ ​​ ​生成文件，注意​ ​​ ​ip​ ​​ ​地址需要用户自己设置​ ​ ​ ​[root@localhost bandwidthd]# gedit /etc/mrtg/mrtg.cfg      //​ ​​ ​修改文件​ ​ ​ ​#  for UNIX​ ​ ​ ​ WorkDir: /var/www/mrtg      //​ ​​ ​当前处于​ ​​ ​centos​ ​​ ​系统，因此这句去掉注释​ ​​ ​.​ ​​ ​这个路径是​ ​​ ​apache​ ​​ ​下的网页路径​ ​ ​ ​#  or for NT​ ​ ​ ​# WorkDir: c:\mrtgdata​ ​ ​ ​### Global Defaults​ ​ ​ ​#  to get bits instead of bytes and graphs growing to the right​ ​ ​ ​ Options[_]: growright, bits    //​ ​​ ​去掉注释​ ​

7、生成html文件，执行三次指令

​ ​[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、在浏览器输入“127.0.0.1/mrtg/192.168.0.113_2.html”,这样就可以访问了
