Server Admin

1. 아파치 Log Lotate 추가하기

아파치 로그는 하나의 파일에 저장을 하면 사이즈가 계속 커져 속도를 저하시킨다.

로그를 잘라서 저장하게 하는 서비스가 Loglotate이다.

# cd /etc/logrotate.d

# vi apache2

/usr/local/httpd/logs/*log {

  missingok

  notifempty

  sharedscripts

  postrotate

  /usr/local/httpd/bin/apachectl reload > /dev/null 2 > &1 || true

  endscript

}

# logrotate -f /etc/logrotate.d/apache2

2. Runlevel 스크립트 추가하기

자동데몬시작을 위해 runlevel 스크립트를 추가해보자

# cd /etc/init.d

# vi apache2

#!/bin/bash

아파치를 재시작해보자

# /usr/local/httpd/bin/apachectl stop

# /etc/init.d/apache2 stop

# /etc/init.d/apache2 start

runlevel에 추가하기위해 아래와 같이 체크한다.

# chkconfig --add apache2
