10.修改MRTG配置文件：
[root@localhost ~]# vi /etc/mrtg/mrtg.cfg
11.新建网页文件存放目录：
[root@localhost ~]# mkdir /usr/local/apache/htdocs/mrtg
12.生成网页文件：
[root@localhost ~]# /usr/local/mrtg/bin/indexmaker /etc/mrtg/mrtg.cfg --output=/usr/local/apache/htdocs/mrtg/index.html --title="MY MRTG" [root@localhost ~]# [root@localhost ~]# cd /usr/local/apache/htdocs/mrtg/ [root@localhost mrtg]# ls index.html 13.启动MRTG： [root@localhost ~]# env LANG=C /usr/local/mrtg/bin/mrtg /etc/mrtg/mrtg.cfg 2013-12-24 05:04:27, Rateup WARNING: /usr/local/mrtg/bin/rateup could not read the primary log file for localhost_2 2013-12-24 05:04:27, Rateup WARNING: /usr/local/mrtg/bin/rateup The backup log file for localhost_2 was invalid as well 2013-12-24 05:04:27, Rateup WARNING: /usr/local/mrtg/bin/rateup Can't remove localhost_2.old updating log file 2013-12-24 05:04:27, Rateup WARNING: /usr/local/mrtg/bin/rateup Can't rename localhost_2.log to localhost_2.old updating log file [root@localhost ~]# env LANG=C /usr/local/mrtg/bin/mrtg /etc/mrtg/mrtg.cfg 2013-12-24 05:04:32, Rateup WARNING: /usr/local/mrtg/bin/rateup Can't remove localhost_2.old updating log file [root@localhost ~]# env LANG=C /usr/local/mrtg/bin/mrtg /etc/mrtg/mrtg.cfg [root@localhost ~]#
PS:上面env LANG=C /usr/local/mrtg/bin/mrtg /etc/mrtg/mrtg.cfg 命令会有错误信息输出，忽略执行三次命令即可
因为mrtg生成的是静态html文件，不断刷新则需要加入计划任务：
重启计划任务：
访问mrtg：
在浏览器输入：http://x.x.x.x/mrtg
MRTG配置文件mrtg.cfg配置文件中参数说明：
mrtg.cfg 里面几个参数的意思.
Target：是要执行的脚本
Xsize：生成图表的横向宽度（最大600）
Ysize：生成图表的纵向高度（最大200）
Title：标题
kMG: Change the default multiplier prefixes
Ytics：纵向划分为几个块（格子）
MaxBytes：图表纵向数值的最大上限
PageTop：页面上面的提示
kilo：一般是写1024，如果需要的话，是1000在计算机里的单位
LegendI：从SHELL返回的数据中的第一个
LegendO：从SHELL返回的数据中的第二个
Options： growright，表示图表向右延展
