우분투(Ubuntu) 20.04에서 APM 설치

지난 시간에 우분투 20.04에서 Apache2 Server와 MariaDB를 설치 및 구동하는 방법에 대해 서술하였습니다. APM으로 구성된 웹서버를 구축하기 위한 마지막 단계로 PHP 7을 설치하는 방법에 대해 적고자 합니다. 여기서는 우분투 20.04 주 업데이트 저장소를 통해 간편하게 설치하는 방법을 알아보도록 하겠습니다.

현재 PHP 안정 버전은 7.4입니다. 그리고 PHP 8.0이 개발되고 있습니다.(이 글을 처음 게시했을 때 Beta 3버전이 공개되었으며 2020년 11월 26일 PHP 8.0이 정식 출시하는 것으로 예정되어 있습니다.

시스템 내 패키지 최신 버전으로 업그레이드 - 패키지 설치 전 필수 작업

study@study-VirtualBox:~$ sudo apt update

등록된 저장소 내 패키지 정보를 최신으로 업데이트해줍니다.

study@study-VirtualBox:~$ apt list --upgradable

업그레이드가 가능한 패키지 목록을 확인합니다.

study@study-VirtualBox:~$ sudo apt upgrade

최신으로 업데이트된 저장소 내 패키지 정보를 바탕으로 시스템에 설치된 패키지들을 최신으로 업그레이드해줍니다.

study@study-VirtualBox:~$ sudo apt autoremove

패키지 업그레이드를 마친 후 불필요해진 패키지를 자동으로 삭제해줍니다.

이글에서는 우분투의 apt 명령어를 사용해 패키지를 업그레이드하는 방법만 보였지만 어떤 리눅스 배포판을 사용하든 간에 새로운 패키지를 설치하기 전에 시스템 내의 패키지들을 전체적으로 업그레이드하여 최신으로 유지해주는 것이 좋습니다.

실제로 각종 패키지의 공식 설치 설명서에서도 최소한 (sudo) apt update와 (sudo) apt upgrade 이 두 명령어가 작업 순서의 맨 처음에 나오는 것을 볼 수 있습니다.

설사 따로 설명이 없더라도 위 작업은 수행되었음을 전제로 진행됩니다.

우분투 20.04의 경우, 우분투 공식 저장소에서 php를 설치하면 PHP 7.4버전이 설치되며 php 패키지만을 지정 설치하면 위와 같이 종속성 패키지가 함께 설치가 진행됩니다.

php 설치시 종속성 설치되는 패키지들 목록

libapache2-mod-php7.4

php-common

php7.4

php7.4-cli php7.4-common

php7.4-json
php7.4-opcache

php7.4-readline

APM 서버를 구축하고자 할 때 권장하는 최소 설치 명령은 다음과 같습니다.

study@study-VirtualBox:~$ sudo apt install php libapache2-mod-php php-mysql

위 명령을 실행하면 APM을 구축하는데 필요한 최소한의 종속성 패키지들이 함께 설치됩니다.

libapache2-mod-php는 Apache2와의 연동에 필요한 라이브러리 패키지이고, php-mysql는 MySQL 계열 DB와 연동할 때 필요한 패키지입니다.

PHP를 설치 하기 전에 Apache2가 정상적으로 설치되어 있어야 합니다. 만약 그렇지 않으면 오류가 발생합니다.

그리고 PHP를 설치하기 전에 MySQL이나 MariaDB 역시 설치하는 것을 권장합니다.

이것으로 PHP 7.4 설치가 완료되지만 APM 웹서버를 정상적으로 구동하기 위해서는 일부 PHP 모듈도 추가로 패키지 설치해주어야 합니다.

PHP 익스텐션(모듈) 설치

PHP 익스텐션 목록과 자세한 설명은 아래 링크에서 확인할 수 있습니다.

https://www.php.net/manual/en/extensions.membership.php

그러나 정보가 오래된 것이 많으므로 알아서 걸러 읽어야 합니다.

2021년 4월 현재 우분투 공식 저장소에서 제공하는 php 익스텐션 패키지들은 총 425개입니다. 물론 각 아키텍처별로 동일한 역할을 하는 패키지들이 같이 존재하므로 실제로 서버 시스템에서 사용할 수 있는 패키지의 수는 줄어듭니다.

PHP 필수 설치 익스텐션

이 목록들 중에서 APM 웹서버 관리자들이 일반적으로 함께 설치하는 필수 설치 모듈은 다음과 같습니다.

study@study-VirtualBox:~$ sudo apt install php-{bz2,intl,gd,mbstring,mysql,zip}

study@study-VirtualBox:~$ sudo apt install php-{bz2,intl,gd,mbstring,mysql,zip}
