MRTG on ubuntu

1.先安裝snmpd
birdy@server:~$ sudo apt-get install snmpd

2.設定snmpd：進/etc/snmp/snmpd.conf去修改如下
#com2sec paranoid default public
com2sec readonly default public

3.重新啟動snmpd
birdy@server:~$ sudo /etc/init.d/snmpd restart

4.安裝mrtg，畫面中會問是否要限制存取/etc/mrtg.cfg的使用者，選YES並接著安裝流程
birdy@server:~$ sudo apt-get install mrtg

5.設定mrtg：先到/var/www/mrtg下
birdy@server:~$ cd /var/www/mrtg
birdy@server:/var/www/mrtg$ sudo cfgmaker --output=/etc/mrtg.cfg public@localhost

輸入指令：一開始會有警告訊息產生，執行3次後就ok了
birdy@server:/var/www/mrtg$sudo env LANG=C mrtg /etc/mrtg.cfg

6.最後建立mrtg的index.htm，就大功告成囉！
birdy@server:~$ sudo indexmaker --output=index.htm /etc/mrtg.cfg

7.開網頁看看成果：http://localhost/mrtg/
