1.安装MRTG
yum -y install zlib libpng freetype libjpeg libxml2 gd-devel
yum -y install net-snmp net-snmp-devel net-snmp-utils mrtg
2.配置文件修改
vi /etc/snmp/snmp.conf //修改snmp配置文件，允许mrtg读取网络接口的流量数据
将
view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.25.1.1
修改为：
view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.2
view systemview included .1.3.6.1.2.1.25.1.1
把下面的#号去掉
#view mib2 included .iso.org.dod.internet.mgmt.mib-2 fc
把下面的语句
access notConfigGroup "" any noauth exact systemview none none
改为：
access notConfigGroup "" any noauth exact mib2 none none
/生成mrtg配置文件/etc/mrtg/mrtg.cfg ,其中public@后接的是你的主机名
cfgmaker --global "WorkDir:/var/www/mrtg" --global "Language:chinese" --global "Options[_]: growright,bits" --output /etc/mrtg/mrtg.cfg public@192.168.20.42
编辑 /etc/cron.d/mrtg,使mrtg每隔2分钟自动运行来生成统计信息
vi /etc/cron.d/mrtg
输入:
*/2 * * * * root LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lock/mrtg/mrtg_l --confcache-file /var/lib/mrtg/mrtg.ok
产生网页索引文件
indexmaker /etc/mrtg/mrtg.cfg --output /var/www/mrtg/index.html --title="MRTG监控"
启动mrtg
env /usr/bin/mrtg /etc/mrtg/mrtg.cfg
修改 /etc/httpd/conf.d/mrtg.conf ，允许任何人访问
Alias /mrtg /var/www/mrtg
<Location /mrtg>
Order deny,allow
# Deny from all
Allow from all
# Allow from .example.com
</Location>
MRTG生成的web页面是静态的，为了能让其不断的刷新，需要将以上命令添加进crontab 。
#crontab -e
添加如下一行
*/2 * * * * env /usr/bin/mrtg /etc/mrtg/mrtg.cfg
注：此行表示每2分钟刷新一次，可以根据自己的需要修改刷新时间间隔。
若监控多台服务器，需要创建多个不同的mrtg.cfg，并添加进crontab 中。
查看端口的开启状况
# netstat -tunlp |grep snmp
新建一个存放脚本的文件夹 /var/www/mrtgsh
===========================内存监控===========================
建立脚本文件 mrtg.memory
#!/bin/bash
# run this script to check the mem usage.
totalmem=`/usr/bin/free |grep Mem |awk '{print $2}'`
usedmem=`/usr/bin/free |grep Mem |awk '{print $3}'`
UPtime=`/usr/bin/uptime | awk '{print $3""$4""$5}'`
echo $totalmem
echo $usedmem
echo $UPtime
===========================CPU监控===========================
使用yum，如何安装iostat
sysstat 使用yum安装
# yum install sysstat
sysstat的安装包是：sysstat-5.0.5-1.i386.rpm，装完了sysstat-5.0.5-1.i386.rpm
后就会有iostat、mpstat、sar、sa的功能，sysstat-5.0.5-1.i386.rpm
启动sysstat
# /etc/init.d/sysstat start
设置sysstat自启动
# /sbin/chkconfig sysstat on
建立脚本文件mrtg.cpu
#!/bin/bash
cpuusr=`/usr/bin/sar -u 1 3 | grep Average | awk '{print $3}'`
cpusys=`/usr/bin/sar -u 1 3 | grep Average | awk '{print $5}'`
UPtime=`/usr/bin/uptime | awk '{print $3 " " $4 " " $5}'`
echo $cpuusr
echo $cpusys
echo $UPtime
echo localhost
===========================http监控===========================
建立脚本文件mrtg.http
#!/usr/bin/perl
$hostname=`hostname`;
$hostname=~s/\s+$//;
$apache_all_conn=`netstat -an|grep :80|wc -l`;
$apache_conn=`netstat -an|grep :80|grep ESTABLISHED|wc -l`;
$apache_all_conn=~s/\n$//;
$apache_conn=~s/\n$//;
$apache_all_conn=~s/^\s+|\s+$//;
$apache_conn=~s/^\s+|\s+$//;
$gettime=`uptime|awk '{print \$1" "\$3" "\$4}'`;
$gettime=~s/\,|\n$//g;
print("$apache_all_conn\n");
print("$apache_conn\n");
print("$gettime\n");
print("$hostname\n");
===========================编辑mrtg.cfg===========================

env /usr/bin/mrtg /etc/mrtg/mrtg.cfg
打开浏览器时发现文字为乱码
解决方案：
vi /etc/httpd/conf/httpd.conf
在740行左右(若是不懂显示行号，可以在打开后命令行输入set nu)将
AddDefaultCharset UTF-8
修改为
AddDefaultCharset GB2312
vi /etc/mrtg/mrtg.cfg 里添加 Language:chinese
