  • RHEL/CentOS, Windows에 PHP apc 설치

 

APC 는 업데이트된지 오래 되었고 PHP 5.5 에서는 지원하지 않으므로 PHP 5.5 부터 내장된  Zend OPcache 를 사용하는 걸 권장한다.

 

Windows

  1. http://dev.freshsite.pl/php-accelerators/apc.html 에서 다운로드 및 압축 해제
    1. Win7/2008 용 다운로드 - php_apc_3114_beta_php54_win7-2008.zip
  2. 파일중에 php_apc.dll를 PHP 설치 폴더내 ext 에 복사
  3. c:\windows\php.ini 에 다음 내용 추가

    extension=php_apc_3114_beta_php54_win7-2008.dll

 

http://windows.php.net/downloads/pecl/releases/apc/에서 배포하는 apc 는 디버그 로그를 출력하는 치명적인 문제가 있어서 사용 불가

Notice: Unknown: 1. h->opened_path=[null] h->filename=[xxxx] in Unknown on line 0 

Notice: Unknown: apc_cache_find [-1302308902] in Unknown on line 0 

 

 

RHEL /CentOS

  1. WebTatic 이나 Remi 저장소 를 설치한다. (RHEL/CentOS php 5.4 설치 참고)
  2. yum 으로 설치

    yum install php54w-pecl-apc
