Part IV. 배포

I. package를 통한 nginx 설치
package를 이용하여 nginx를 설치한다.

$ sudo apt update
$ sudo apt install nginx
$ nginx -v
nginx version: nginx/1.4.6 (Ubuntu)

$ sudo service nginx start

$ sudo service nginx status
 * nginx is running


http://localhost/
Welcome to nginx!
If you see this page, the nginx web server is successfully

II. Nginx Setting
Django를 이용해서 서버에 요청을 보낼 수 있도록 Nginx 설정 파일을 생성한다.

/etc/nginx/sites-available/sotolab

server {
    listen 80;
    server_name sotolab;

    location / {
        proxy_pass http://localhost:8000;
    }
}
이 설정은 로컬 포트 8000으로 들어오는 모든 요청을 Django로 보내서 응답하도록 한다


$ sudo ln -s /etc/nginx/sites-available/sotolab /etc/nginx/sites-enabled/sotolab
$ ls -l /etc/nginx/sites-enabled


$ sudo rm /etc/nginx/sites-enabled/default


$ sudo service nginx reload

$ cd workspace/django
$ source myvenv/bin/activate
$ cd start_django
$ python manage.py runserver
