우분투 Ubuntu 20.04 LTS 컴포저 Composer 설치하기

요즘 뭐만 하면 컴포저(Composer)로 설치해야하는데 컴포저를 모르면 여러가지로 불편한 것 같습니다.
이번에는 우분투(Ubuntu) 서버에 컴포저를 설치해보겠습니다.

Composer 설치에 앞서

가상서버는 iwinv.kr에서 생성했습니다.
작성속도를 높이기 위해 모든 문장에 높임법을 사용하지 않겠습니다. (여기부터 시작)
본인도 초보라 문제 해결 능력은 떨어지지만 앞으로 자주하게 될 것 같아 여기에 기록한다.

먼저 서버는 저번에 작성한 포스팅을 토대로 iwinv에서 서버 생성 후 APMariaDB로 설치했다.
최근 iwinv에서 뭔가 큰 사고가 있었다는데 (잘 모름) 그래도 iwinv가 가성비가 좋은 것은 어쩔 수 없다 (고 한다..)

우분투 ubuntu 20.04 LTS APM(Apache2 + PHP8 + MariaDB) 설치

하기의 모든 명령어는 sudo su를 실행 후 입력하는 것을 기본으로 한다.
iwinv의 경우 별도 작업없이 서버 생성 후 메일로 온 비밀번호를 사용하여 로그인 하면 루트 권한이므로 이 작업은 안해도 된다.

ubuntu@ip-000-000-000-000:~$ sudo su
root@ip-000-000-000-000:/#

컴포저 설치는 간단하다.

설치 후 마지막에 버전을 확인하려고 composer -v 를 입력했지만 관리자 계정으로는 컴포저를 실행할 때 경고메세지를 띄웠다.
이번에는 컴포저로 무언가 설치 하려는게 아니니 신경쓰지말고 엔터를 눌러주자. (하단 12번째 줄 참고)

root@ip-000-000-000-000:/# curl -sS https://getcomposer.org/installer | php
