알아두면 유용한 apache httpd실행 옵션

httpd는 아파치의 데몬 실행파일 입니다.

옵션을 통해 유용한 정보를 얻어 봅시다.

[아파치 conf파일 바꿔 기동하기]

./httpd -f /usr/local/apache/conf/httpd.conf

./httpd -f /usr/local/apache/conf/httpd_abc.conf

보통 기본 위치에 존재하는 httpd.conf를 이용하여 아파치를 실행하나,

두개 이상의 설정 파일을 두고 서비스마다 따로 띄운다거나 등에 사용할 때 유용합니다.

./httpd -f /usr/local/apache/conf/httpd.conf
