LAMP(Linux, Apache2, MariaDB 및 PHP-FPM)에 WordPress 웹사이트가 2개 있습니다.
mpm-prefork를 비활성화하고 mpm-worker 또는 mpm-event를 활성화하면 Apache는 빈 페이지만 표시합니다(워드프레스 웹사이트가 몇 개 있습니다).
이상한 점은 로그에 문제에 대한 내용이 전혀 없다는 것입니다.
다음과 같은 Apache 구성이 있습니다.
VirtualHost configuration:
*:80 is a NameVirtualHost
default server www.example.com (/etc/httpd24/conf.sh/example-80.conf:1)
port 80 namevhost www.example.com (/etc/httpd24/conf.sh/example-80.conf:1)
alias example.com
port 80 namevhost www.sub.example.com (/etc/httpd24/conf.sh/sub-80.conf:1)
alias sub.example.com
*:443 is a NameVirtualHost
default server ip-172-31-0-20.ec2.internal (/etc/httpd24/conf.d/ssl.conf:56)
port 443 namevhost ip-172-31-0-20.ec2.internal (/etc/httpd24/conf.d/ssl.conf:56)

디버깅하려면 ErrorLog LogLevel을 켜보세요.
