반응형
안녕하세요.
오늘은 python 장고를 설치해보겠습니다
django version 은 3.0.8입니다
1. pip 설치
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py
설치 확인
pip3 --version
2. virtualenv (가상머신) 설치
pip3 install virtualenv virtualenvwrapper
vi ~/.bashrc
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
export VIRTUALENVWRAPPER_VIRTUALENV_ARGS=' -p /usr/bin/python3 '
export PROJECT_HOME=$HOME/Devel
source /usr/local/bin/virtualenvwrapper.sh
//바로적용
source .bashrc
3. django 설치
pip3 install django
프로젝트 생성
django-admin startproject 프로젝트명
4. django 웹서버 실행
./manage.py runserver
한번에 되면 참 좋으나
가끔 이런 에러가 발생합니다

잘 읽어보면 SQLite 3.8.3 or later is required (found 3.7.17).
sqlite 버전이 낮아서 발생한 오류였습니다
5. sqlite version update
다운로드
curl -O https://sqlite.org/2020/sqlite-autoconf-3320300.tar.gz
// 압축해제
tar -xvzf sqlite-autoconf-3320300.tar.gz
configure
sudo LD_RUN_PATH=/usr/local/lib ./configure --enable-optimizations
또 에러발생!
configure: error: in `/root/sqlite-autoconf-3320300':
configure: error: no acceptable C compiler found in $PATH
에러는 gcc가 없다는 에러였어요
gcc 설치
yum -y install gcc
다시 설치
sudo LD_RUN_PATH=/usr/local/lib ./configure --enable-optimizations
sudo LD_RUN_PATH=/usr/local/lib make install
파이썬 접속하여 버전 갱신
python3
import sqlite3
sqlite3.sqlite_version
6. 웹서버 실행
sudo nohup python3 manage.py runserver 0.0.0.0:8000
HOSTS 에러 발생
생성한 프로젝트에 settings.py 파일에 ALLOWED_HOSTS를 입력해줘야한다
이렇게 화면이 나온다면 프로젝트 생성을 성공한 것 입니다
