composer를 명령어로 설치하려고 했는데, .so파일 관련해서 오류가 떴다.
즉, PHP 환경 구성 오류로 발생하는 문제이다.
이런 PHP 확장 모듈을 정상적으로 로드할 수 있어야, composer과 같은 라이브러리를 설치할 수 있는 것이다.

해결방법

시도 1. php 확장 모듈 새로 설치

sudo apt-get update
sudo apt-get install php-cli php-xml php-mbstring php-curl php-mysql php-zip php-gd php-intl php-soap php-json php-xmlrpc

Ubuntu 시스템에서는 다음과 같은 명령어를 사용하여 필요한 PHP 확장 모듈을 설치할 수 있다.
하지만, 나는 이 방법이 통하지 않았다


시도 2. PHP 구성 파일 확인
php.ini 파일에서 확장 모듈 경로가 정확히 설정되었는지 확인한다.

http://본인의 ip주소/info.php (웹경로) 로 들어가 보았더니 확장 모듈 경로도 잘 설정되어 있었다.
도대체 어디서 문제가 생긴것일까?


시도 3. 확장 모듈의 경로 확인

php -i | grep extension_dir

다음 코드를 작성하여 문제를 일으키는 확장모듈의 경로를 확인한다.

php.ini와 같은 설정 파일이 여러개 존재할 수 있다.
따라서, 내가 확인한 아파치의 php.ini가 아닌 다른 곳의 php.ini에서 extension_dir 설정이 상대 경로인 ./로 되어 있다.
이는 PHP가 현재 작업 디렉토리에서 확장 모듈을 찾도록 설정되어 있음을 의미한다.
이 설정은 확장 모듈이 존재하는 /usr/lib/php/20210902 (웹에서 찾은 경로)와 일치하지 않기 때문에 문제가 발생하고 있는 것이다.


따라서, 다른 곳의 php.ini가 어떤 경로에 위치해 있는지 찾아야 했다.

php --ini

다음 명령어를 입력하면, 이렇게 뜬다

Configuration File (php.ini) Path: /etc/php/8.1/cli
Loaded Configuration File:         /etc/php/8.1/cli/php.ini
Scan for additional .ini files in: /etc/php/8.1/cli/conf.d
Additional .ini files parsed:      /etc/php/8.1/cli/conf.d/10-mysqlnd.ini,

php.ini가 cli 폴더에도 존재한다.
 /etc/php/8.1/cli/php.ini의 extension_dir 설정을 /etc/php/8.1/apache2/php.ini 와 같은 것으로 바꾸었다.

다시 composer를 설치하는 명령어를 입력하니, 잘 설치가 된다.
문제해결!

왜 이딴 문제가 생기는 걸까?

PHP에서 /etc/php/8.1/cli/php.ini와 /etc/php/8.1/apache2/php.ini 파일이 서로 다르게 설정되어 있는 이유는 각 환경(명령줄 인터페이스와 웹 서버)에 최적화된 설정을 제공하기 위해서다. 각각의 설정 파일은 다음과 같은 용도로 사용된다:

CLI (cli/php.ini): 이 파일은 PHP를 커맨드 라인 인터페이스(CLI)로 실행할 때 사용된다. 예를 들어, 스크립트를 직접 터미널에서 실행하거나 배치 작업, 크론 작업을 처리할 때 해당 설정이 적용된다. CLI 환경에서는 웹 서버와 연관된 설정(예: 세션 타임아웃, 최대 실행 시간 등)이 필요 없거나 다르게 설정될 수 있다.
Apache (apache2/php.ini): 이 파일은 Apache 웹 서버를 통해 PHP가 실행될 때 사용된다. 웹 서버 환경은 CLI 환경과 다르게, HTTP 요청 및 응답을 처리하는 데 필요한 특정 설정이 필요하다. 예를 들어, 요청당 메모리 한도, 실행 시간 제한, 파일 업로드 설정 등이 이에 해당한다.
