nginx + mariadb10.2+php7.1에서 라이믹스를 설치중인데 마지막에 500에러가 뜹니다 ㅠ_ㅠ

안녕하세요!

타운분들덕에 열심히 서버 세팅을 배우고 있는 안개입니다^^

DB까지 입력하고 관리자 정보를 입력하고 마무리를 하려는 순간!

떡 하고 500에러가 뜨고 있습니다 ㅠ_ㅠ

세팅은 

nginx 1.12  + mariadb10.2+php7.1이구요.

간신히 php-fpm까지 연동이 끝났습니다.

많은 분들이 500관련해서 이러한 에러가 뜨는것 같아 도움이 될지도 모른다는 생각에 이렇게 조언을 구하고자 글을 올립니다.

nginx에러 로그 파일을 보면 아래와 같이 나온답니다.

솔직히...-ㅁ-;1~10줄까지는 대충은 알겠는데(실제 폴더에서 확인하니 파일이 없더라구요)

나머지는 진짜 모르겠습니다.

실력자 분들께 조언을 구하고자합니다 =0=;

설치 화면만 나오실꺼예요 ㅎ;설치에서 진행이 안되서요
