nginx-php'；不要使用自己构建的nginx

我用这个配置命令编译了NGINX：

./configure --with-http_ssl_module --add-module=../nginx-rtmp-module-master

然后我安装了它，它已经成功添加，但我不能执行PHP文件，当我试图打开页面时，它给了我一个错误：（（我已经安装了PHP-fpm）

这是我的nginx.conf文件：

#user  nobody;
worker_processes  1;
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
#pid        logs/nginx.pid;

events {
    worker_connections  1024;
}

这是错误日志输出：

看起来好像没有权限，但我如何才能给nginx正确的权限？
