서버에 mrtg 설치하기

1. snmp 설치
# yum install net-snmp
# yum install net-snmp-utils
# yum install net-snmp-devel 

2. mrtg 설치
# yum install mrtg*

3. snmp 설정
# vi /etc/snmp/snmpd.conf (first, second, third, final 섹션만 변경)

# first
com2sec local localhost webnics

# second
group localgroup v1 local
group localgroup v2c local
group localgroup usm local

# third
view all included .1 80
view systemview included system

# final
access localgroup “” any noauth exact all none none

* webnics는 community 값이라고 하는데… 쉽게 설명해 접근하는 계정?  이라고 합니다.

# snmpwalk -v 2c -c webnics localhost (설정 확인하기)

4. cfg 생성
# cfgmaker –global ‘WorkDir: /ft/mrtg/’ –global ‘Language: korean’ –global ‘Options[_]: bits,growright’ -output /etc/mrtg/mrtg.cfg webnics@localhost

WorkDir: /ft/mrtg/ –> 내 웹소스 있는경로에 mrtg디렉토리 만들면됩니다.

5. index 생성
indexmaker –title “Title” –output /website/mrtg/index.htm /etc/mrtg/mrtg.cfg

6. cron 등록
# crontab -e
*/5 * * * * root /usr/sbin/mrtg /etc/mrtg/mrtg.cfg
