Nginx错误：FastCGI在读取上游的响应头时发送了stderr："主要脚本未知"

Question

我有一个 yii2 高级模板应用程序在 centos 9 上运行，带有 nginx 和 php 8.1。设置虚拟主机配置如下：

server {
    lis ten 80;
    server_name mydomain.com;

    root /home/lamtab/xp-app-main/app/appadmin/web;
    index index.php index.html index.htm index.nginx-debian.html;

    access_log "/var/log/nginx/mydomain.com.access.log";
    error_log "/var/log/nginx/mydomain.com.error.log";

    location / {
       try_files $uri /index.php$is_args$args;
    }
   location ~* .php$ {
                # With php-fpm unix sockets
                fastcgi_pass unix:/run/php-fpm/www.sock;
                include         fastcgi_params;
                fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;
                fastcgi_param   SCRIPT_NAME        $fastcgi_script_name;
        }
    fastcgi_buffers 8 16k;
    fastcgi_buffer_size 32k;
    fastcgi_connect_timeout 90;
    fastcgi_send_timeout 90;
    fastcgi_read_timeout 90;
}

域的错误日志报告

FastCGI 在 stderr 中发送：“主脚本未知”，同时从上游读取响应标头...”

以及nginx的错误日志报告

index.php”失败（13：权限被拒绝）

有什么线索吗？

就我而言，我白白浪费了几个小时，结果我只需要在 ubuntu 22.04 中重新启动 php8.1-fpm 服务。尝试一下也许会有帮助。我的conf文件看起来像这样

server {
   listen   80 default_server;
   root /home/user/your_project/public/;
   index index.php index.html index.htm;
   access_log /home/user/your_project/nginx-access.log;
   error_log /home/user/your_project/nginx-error.log;
   server_name localhost;

location / {
     try_files $uri $uri/ /index.php$is_args$args;
}

location ~ \.php$ {
    try_files $uri index.php =404;
    fastcgi_pass unix:/var/run/php/php8.1-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
   }
}
