[Django] 리눅스서버상에서 Django 환경 구축하기 - SQLite 도 설치

http://portfolio.wonpaper.net 2023. 6. 12. 20:36

필자의 Centos7 리눅스서버 환경에서 셋팅하였다.

1. Python3 설치

2. Django 설치

 

일단 새로운 django 가상환경을 위해 임의의 폴더 alzssol_django 을 만들었다.

mkdir alzssol_django

cd alzssol_djang

 

pip3 --version  [pip3 버전확인]

virtualenv --version [virtualenv 버전확인]

 

virtualenv 설치한다.

pip3 install virtualenv

 

venv 이름으로 가상환경을 설정한다.

virtualenv venv

Django 는 8000 포트를 기본으로 하는데, 외부서버에 셋팅하는 거라 방화벽으로 8000번을 풀어 주어야 한다.
