nginx 网站显示空白页。无错误

Question

背景

我正在尝试在 Alpine Linux 服务器上启动并运行一个 nginx /php-fpm7 站点。

问题

当我导航到它时没有出现任何错误。证书很好。并且在 /var/log/access.log 文件中，我看到一个 GET 请求到达该站点。但是...我在 /etc/nginx/conf.d/default.conf 中定义的网站/应用程序未被加载/触发。我应该看到一个登录页面。以下是各种工件：

我检查过的内容

nginx 正在运行并监听。php-fpm 也在运行并监听

mywww:/etc/nginx/conf.d# netstat -lnp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      3979/php-fpm.conf)
tcp        0      0 0.0.0.0:443             0.0.0.0:*               LISTEN      4480/nginx.conf

nginx.conf 加载 /etc/nginx/conf.d/default.conf 中的所有配置

 mywww:/etc/nginx# cat nginx.conf | grep conf.d
    include /etc/nginx/conf.d/*.conf;

default.conf 如下所示：

server {
        listen 443 ssl;
        root /var/www/mywebapplication.com/public;
        server_name mywebbapplication.com;

        ssl_certificate /etc/ssl/a/bundle.crt;
        ssl_certificate_key     /etc/ssl/a/thekey.key;
        ssl_protocols   TLSv1 TLSv1.1 TLSv1.2;

        error_log /var/log/nginx/mywebapplication.log notice;
        index login.php;
        allow all;

        location / {
                try_files $uri $uri/ /=404;
        }

        location ~ \.php$ {
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_index login.php;
                include fastcgi_params;
        }
}

登录页面存在：

  mywww:/etc/nginx# ls -lah /var/www/mywebapplication.com/public/login.php
 -rw-r--r--    1 root     root          66 Apr 25  2019 /var/www/mywebapplication.com/public/login.php

Nginx 访问日志文件：

198.1.2.1 - - [24/Mar/2020:15:06:25 +0000] "GET / HTTP/1.1" 200 5 "-" "Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebK│it/537.36 (KHTML, like Gecko) Chrome/80.0.3987.122 Mobile Safari/537.36" "-"                                                                 │

进程正在运行的用户/组：

mywww:/var/www/mywebapplication.com/public# ps aux | grep php
 3979 root      0:00 {php-fpm7} php-fpm: master process (/etc/php7/php-fpm.conf)
 3986 nginx     0:00 {php-fpm7} php-fpm: pool www
 3987 nginx     0:00 {php-fpm7} php-fpm: pool www
 4716 root      0:00 vim /etc/init.d/php-fpm7
 4719 root      0:00 grep php

nginx 的用户是“nginx”：

mywww:/etc/nginx# cat /etc/nginx/nginx.conf | grep user   
user nginx nginx;

nginx 主进程以 root 身份运行可以吗？

不确定我还应该检查什么。
