nginx 1.25.1의 change log 살펴보니

Changes with nginx 1.25.1                                        13 Jun 2023
    *) Feature: the "http2" directive, which enables HTTP/2 on a per-server
       basis; the "http2" parameter of the "listen" directive is now
       deprecated.
    *) Change: HTTP/2 server push support has been removed.
    *) Change: the deprecated "ssl" directive is not supported anymore.
    *) Bugfix: in HTTP/3 when using OpenSSL.

http2 에 대해서 설정하는 방법이 달라졌고, per-server 단위 설정이 가능하다고 한다.

기존의 설정인

  ssl_certificate server.crt;  
  ssl_certificate_key server.key;  
}

에서

server {  
    listen 443 ssl;  
    http2 on;  
    ssl_certificate server.crt;  
    ssl_certificate_key server.key;  
}

으로 변경 됐다.

  location / {
    return 200;
  }
