我写的东东,虽然顶的人少!但我依然涛声依旧!还写..
FREEBSD6.0上安装snmp+mrtg还是比较简单的，不过网络上的安装教程大多缺胳膊少腿，有的难度挺高,理论说了一大推,让人忘而怯步呀!今天偶来发一篇简单易懂的.为新手准备的.如果你已经安装好了apache的话，看下面：
一：安装snmp：
以下%为SHELL提示符，
安装snmp:
%cd /usr/ports/net-mgmt/net-snmp
%make install
修改/etc/rc.conf:
%ee /etc/rc.conf
加入：
------------------------------------------------------------------
snmpd_enable="YES"
snmpd_flags="-a -p /var/run/snmpd.pid"
snmptrapd_enable="YES"
snmptrapd_flags="-a -p /var/run/snmptrapd.pid"
------------------------------------------------------------------
运行下：
%/etc/netstart
编辑snmpd.conf：
%ee /usr/local/share/snmp/snmpd.conf
加入一行：
-------------------------------------------------------------
rocommunity public #默认让snmp使用public用户
--------------------------------------------------------------
启动snmpd:
%/usr/local/etc/rc.d/snmpd.sh start
二：安装mrtg:
确定ports下的mrtg在什么位置：
%whereis mrtg
mrtg: /usr/ports/net-mgmt/mrtg
安装mrtg:
%cd /usr/ports/net-mgmt/mrtg
%make install
进入你apache的data目录（视个人情况而定，我的是/usr/local/www/apache22/data/wh-hisense/）：
%cd /usr/local/www/apache22/data/wh-hisense
在当前的WEB目录创建mrtg的目录：
%mkdir mrtg
三：配置mrtg：
进入mrtg的配置文件所在目录：
%cd /usr/local/etc/mrtg
用cfgmaker创建mrtg的配置文件：
%/usr/local/bin/cfgmaker public@mail.ahcbd.net > mrtg.cfg
记得将上面的mail.ahcbd.net换成你的主机名，或IP地址.
编辑mrtg.conf:
%ee mrtg.cfg
修改如下：
#####################################
WorkDir: /usr/local/www/apache22/data/wh-hisense/mrtg #注:去掉前面的#号哟,冒号后面不要有空格,否则会出错.
Language: gb2312 #注:这表示简体中文版,,这可是自己加上去的哦!!!

并在文件尾加入,既cpu，内存等的监视：

--------------------------------------------------------------------------------------
记得将上面每处的mail.ahcbd.net换成你的主机名。且更改上面CPU，MEM等各部分的排列顺序等同于其在网页中的排列顺序
生成index.html文件：
/usr/local/bin/indexmaker –-title="流量监控" --output=/home/http/mrtg/index.html mrtg.cfg
多运行几次:
/usr/local/bin/mrtg mrtg.cfg
直到没有出错提示为止
加入crontab每隔2分钟让数据刷新一次:
%ee /etc/crontab
------------------------------------------------------------------------
*/2 * * * * root /usr/local/bin/mrtg /usr/local/etc/mrtg/mrtg.cfg
--------------------------------------------------------------------
现在你可以用http://yourdomain.domain/mrtg/看到了。
End!
看希望顶的人越多,鼓励一下嘛!CU的老少爷们.... |
