[전제사항]

당삼 설치하기전에 apache, php 는 깔려있어야한다. 알아서 설치 하세요


=> php 설치 확인

php  -- version, php  --modules

 => apache 설치

# wget http://apache.mirror.cdnetworks.com/httpd/httpd-2.2.29.tar.gz
# mkdir /usr/local/server/apache/
# mv ./httpd-2.2.29.tar.gz usr/local/server/apache/
# tar zxvf httpd-2.2.29.tar.gz (알아서 푸세요..)
# cd httpd-2.2.29.tar.gz (안 옮기고 설치하셔도 됩니다)
# ./configure --prefix=/usr/local/server/apache/
# make && make install

=> apache 확인

# cd..
# ./bin/httpd -V

http://localhost/ 접속
 

 

1. MRTG설치

 

# yum install mrtg

또는 컴파일 설치 (아래설명은 컴파일로 설치한 디렉토리 기준으로 설명합니다.)

# rpm -qa zlib gd libpng       ===> 3가지 라이브러리 설치 확인.
--------------------------------------------------------------------------------------
gd-2.0.33-9.4.el5_4.2
libpng-1.2.10-7.1.el5_5.3
zlib-1.2.3-3
--------------------------------------------------------------------------------------
만약 미설치시 # yum install zlib gd libpng 설치.

# wget http://oss.oetiker.ch/mrtg/pub/mrtg-2.16.4.tar.gz
# tar xvfz mrtg-2.16.4.tar.gz
# cd mrtg-2.16.4
# ./configure --prefix=/usr/local/server/mrtg/
--------------------------------------------------------------------------------------
** Ooops, one of many bad things happened:

   a)  You don't have the GD library installed.
       Get it from http://www.boutell.com, compile it and
--------------------------------------------------------------------------------------
=> 위와 같은 문구가 나올 시, 아래와 같이 설치하고 다시 하세요

# yum install gd-devel
--------------------------------------------------------------------------------------

# make && make install

# cd /usr/local/server/mrtg/
# mkdir www conf
--------------------------------------------------------------------------------------
/usr/local/server/mrtg/www      mrtg 결과물 페이지(웹 홈디렉토리)
/usr/local/server/mrtg/conf     mrtg 설정파일(.cfg) 저장위치
/usr/local/server/mrtg/bin      mrtg 실행파일 (mrtg, cfgmaker, indexmaker) 저장위치
--------------------------------------------------------------------------------------

 

2. RRDTOOL설치

 

# rpm -qa freetype libart_lgpl     ===>2가지 라이브러리 설치확인.
--------------------------------------------------------------------------------------
libart_lgpl-2.3.17-4
freetype-2.2.1-28.el5_5
--------------------------------------------------------------------------------------
만약 미설치시 # yum install freetype libart_lgpl 설치.

# wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.4.4.tar.gz
# tar xvfz rrdtool-1.4.4.tar.gz
# cd rrdtool-1.4.4
# ./configure --prefix=/usr/local/server/rrdtool --disable-python --disable-tcl
# make && make install

--------------------------------------------------------------------------------------
/usr/local/server/rrdtool/      rrdtool 설치 경로
/usr/local/server/mrtg/bin      rrdtool 실행파일 저장위치
--------------------------------------------------------------------------------------

 

 

3. 트래픽 보기 설정.(여기서는 리눅스 서버 자기꺼 한대만 하기로한다.)
