아파치 Worker 컴파일
– 기본적으로 RPM으로 아파치를 설치하게되면 기본설정이 prefork입니다.
prefork 말고 아파치에서 worker방식을 사용하기 위해 아파치 컴파일을 진행하였습니다.
httpd-2.2.17.tar
OS : RHEL5.5 64BIT
/httpd-2.2.17/server/mpm/worker/worker.c
| – 아래 부분 수정 #Ifndef DEFAULT_SERVER_LIMIT #define DEFAULT_SERVER_LIMIT 16 -> 128 <= 변경 #endif |
위의 부분만 설정 후 컴파일을 하면 됩니다.
| ./configure \ –prefix=/usr/local/apache2 \ –enable-so \ –enable-ssl \ –with-mpm=worker \ make |
컴파일후
/usr/local/apache2/bin/apachectl -V를 입력하면 worker 방식으로 동작하는 것을 확인할 수 있습니다.
