http：// localhost /上的nginx drop 403错误

Question

有新安装的nginx。它在localhost上丢弃了403错误。试图制作任何虚拟主机，但出现同样的问题。有同样的错误。尝试了几天不同的配置 - 没办法。正如我验证的那样 - 我对/ var / www有正确的权限。有我的nginx.conf

user root;
worker_processes 4;
pid /var/run/nginx.pid;

events {
        worker_connections 768;
}

http {
        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;

        include /etc/nginx/mime.types;
        default_type application/octet-stream;

        access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;

        gzip on;
        gzip_disable "msie6";

server {
   listen         80;
   listen   [::]:80 default ipv6only=on; 
   server_name  localhost;
   root   /var/www;
   index  index.html index.htm index.php;

   location ~ \.php$ {
       fastcgi_pass 127.0.0.1:7777;
       fastcgi_index  index.php;
       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
       fastcgi_buffers 256 128k;
       fastcgi_connect_timeout 300s;
       fastcgi_send_timeout 300s;
       fastcgi_read_timeout 300s;
       include fastcgi_params;
    }
  }
}

我该怎么做？
