Answer 1

您的配置文件配置错误nginx。

首先，您在节内指定root和index指令location \。

location / {

        root  /data/web;

        index index.html index.htm;

}

该部分仅在所有其他部分不匹配时才起作用，因为它具有短路掩码长度（/是一个符号）

每个URL以.php、 likephpinfo.php或结尾的都index.php将匹配到location ~ \.php$部分：

location ~ \.php$ {

        try_files            $uri = 404;

        fastcgi_pass         unix:/run/php/php7.2-fpm.sock;

        fastcgi_index        index.php;

        include              fastcgi_params;

        fastcgi_read_timeout 300;

}

但是 - 没有rootandindex指令（顺便说一句，index这是可选的，但在您的情况下，first 是强制性的）。

有两种解决方案：

首先，在部分中指定root和index指令location ~ \.php$：

location ~ \.php$ {

        try_files            $uri = 404;

        root                 /data/web;

        index                index.php index.html index.htm;

        fastcgi_pass         unix:/run/php/php7.2-fpm.sock;

        fastcgi_param        SCRIPT_FILENAME $document_root/$fastcgi_script_name;

        fastcgi_index        index.php;

        include              fastcgi_params;

        fastcgi_read_timeout 300;

}

第二个是将rootand放在index全局上下文中（在 内部server）：

server {

    listen 80;

    charset UTF-8;

    server_name example.com www.example.com;

    root  /data/web;

    index index.php index.html index.htm;

    ...

}

UPD：还fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;必须在之后添加指令fastcgi_pass
