yum install gcc* perl* gd* libpng* zlib* -y
cd /usr/local/src
wget http://oss.oetiker.ch/mrtg/pub/mrtg-2.17.4.tar.gz
tar xvfz mrtg-2.17.4.tar.gz
cd mrtg-2.17.4
./configure --prefix=/usr/local/mrtg-2 \
--with-gd=/usr/local/src/gd \
--with-z=/usr/local/src/zlib \

make && make install
4. MRTG 설정
1) 웹설정 (<Directory> 설정)
adduser mrtg
mkdir /home/mrtg/public_html
mkdir /home/mrtg/public_html/localhost
mkdir /home/mrtg/conf
chmod 755 /home/mrtg
chown mrtg.mrtg /home/mrtg
vi /etc/httpd/conf/httpd.conf
<IfModule mod_userdir.c>
# UserDir disabled
UserDir public_html
</IfModule>
<Directory /home/*/public_html>
AllowOverride FileInfo AuthConfig Limit
Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec
<Limit GET POST OPTIONS>
Order allow,deny
Allow from all
</Limit>
<LimitExcept GET POST OPTIONS>
Order deny,allow
Deny from all
</LimitExcept>
</Directory>
2) cfgmaker
(모니터링할 대상항목의 Config 파일을 생성하는 작업 입니다.)
cd /usr/local/mrtg-2/bin
./cfgmaker --global 'WorkDir: /home/mrtg/public_html/localhost' \
--global 'Options[_]: bits,growright' \
--output /home/mrtg/conf/mrtg.cfg \
public@192.168.99.1
3) 모니터링 Config 수정
(/home/mrtg/cfg/mrtg.cfg 하단부에 추가 합니다.)
vi /home/mrtg/conf/mrtg.cfg

4) indexmaker 및 mrtg 쿼리
cd /usr/local/mrtg-2/bin
./indexmaker --title "Localhost" /home/mrtg/conf/mrtg.cfg > \
/home/mrtg/public_html/localhost/index.html
env LANG=C /usr/local/mrtg-2/bin/mrtg /home/mrtg/conf/mrtg.cfg
5. 웹사이트 및 crontab 적용
1) 리다이렉션 페이지 생성
cat > /home/mrtg/public_html/localhost/index.html
<meta http-equiv="refresh" content="1;url=./localhost/index.html">
2) 모니터링 스크립트 작성 및 crontab 등록
[root@localhost bin]# mkdir /script
[root@localhost bin]# cat > /script/mrtg.sh
#!/bin/bash
env LANG=C /usr/local/mrtg-2/bin/mrtg /home/mrtg/conf/mrtg.cfg
crontab -e
