WordPress와 함께 설치한 Ubuntu 16.04는 계속해서 apache2 프로세스를 열어 메모리를 차지합니다.

서버를 완전히 다시 시작하면 서버가 정상적으로 작동됩니다. 웹 사이트를 방문하고 일부 링크를 클릭하면 apache2 프로세스가 생성되지만 종료되지 않으며 서버가 기본적으로 충돌할 때까지 점점 더 많은 메모리를 차지합니다. 이 문제를 해결하는 유일한 방법은 apache2 서비스를 다시 시작하여 모든 프로세스를 종료하거나 서버를 다시 시작하는 것입니다.

내 시도에는 기본 WordPress 테마를 복원하고 모든 플러그인을 비활성화한 다음 사이트를 다시 탐색하는 것이 포함되었지만 이후에도 문제가 지속되는 것 같았습니다. 또한 apache.conf 및 php.ini 파일에서 약간의 구성을 시도했습니다.

나는 지금 혼란스러워서 문제를 파악하기 위해 조사를 해봤지만 막다른 골목에 부딪혔습니다.

내 질문은 왜 apache2와 mysqld가 그렇게 많은 메모리를 차지하고 이를 방지하면 내 서버가 충돌하는 것을 방지할 수 있느냐는 것입니다.

아래는 Apache가 메모리를 차지하고 여러 apache2 프로세스를 생성하는 것을 보여주는 현재 실행 중인 프로세스의 이미지입니다.

여기에 이미지 설명을 입력하세요.

답변2

이미지를 보면 아파치보다 메모리를 더 많이 소비하는 것 htop같습니다 . mysqld도움이 될 수 있는 몇 가지 일반적인 솔루션을 제공하려고 노력했습니다.

  1. mysqld에서 매개변수를 조정해 보세요 /etc/my.cnf. 메모리 소비를 줄이는 방법을 Google에 문의하세요 mysql.

  2. apache/nginx+의 메모리 사용량은 Apache를 직접 사용하는 것 php-fpm보다 php적다고 생각합니다. 두 경우 모두 최대 스레드 수 php, 스레드당 메모리 등을 제어할 수 있습니다. 거기에 약간의 조정을 해주세요.

  3. 가장 중요한 것은 mysqld로그 apache2파일 등을 분석하는 것입니다. man기본 로그 파일 위치에 대한 페이지를 읽고 오류를 찾으십시오.

그것이 도움이 되기를 바랍니다.
