- 내가 실수한  부분

nginx 502 badgate error : https://blog.gomgom.io/502-bad-gateway-solution-on-nginx-php_fpm/

ubuntu 언어셋 문제 : https://zunonia.wordpress.com/2014/02/27/ubuntu%EC%97%90%EC%84%9C-%EC%96%B8%EC%96%B4%EC%85%8B%EC%9D%B4-%EA%B4%80%EB%A0%A8-%EC%97%90%EB%9F%AC-%EC%B2%98%EB%A6%AC%EB%B2%95/

sudo nano /etc/nginx/sites-available/default 에서 /php7.0-fpm.sock; 

내가 설치한 건 7.1인데 7.0으로 입력해서 php파일을 열면 502 에러 발생했음

7.1로 변경함

     # pass PHP scripts to FastCGI server
        #
        location ~ \.php$ {
