Nginx 403禁止所有文件 [英] Nginx 403 forbidden for all files

问题描述

我在CentOS 5盒子上安装了nginx和PHP-FPM，但是很难为它提供任何文件 - 无论是否为PHP。

Nginx以www-data：www-data运行，默认的欢迎使用nginx on EPEL站点（由root：root拥有644权限）加载。

nginx配置文件对 / etc / nginx / sites-enabled / *。conf，有一个include指令，我有一个配置文件 example.com.conf ：

  server {
 listen 80; 
 
虚拟主机名
 server_name www.example.com example.com; 
 
 
 location / {
 root /home/demo/sites/example.com/public_html; 
 index index.php index.htm index.html; 
} 
 
 location〜\.php $ {
 fastcgi_pass 127.0.0.1:9000; 
 fastcgi_index index.php; 
 fastcgi_param PATH_INFO $ fastcgi_script_name; 
 fastcgi_param SCRIPT_FILENAME /home/demo/sites/example.com/public_html$fastcgi_script_name; 
 include fastcgi_params; 
} 
} 
  

尽管public_html由www-data拥有：www-数据具有2777文件权限，此站点无法提供任何内容 -

  [error] 4167＃0：* 4 open /home/demo/sites/example.com/public_html/index.html失败（13：权限被拒绝），客户端：XX.XXX.XXX.XX，服务器：www.example.com，请求：GET / index .html HTTP / 1.1，host：www.example.com
  

其他帖子，用户从nginx获得403s，但我看到的大多数涉及到更复杂的设置与Ruby / Passenger（在过去我实际上已成功）或只是接收错误时，上游PHP-FPM涉及，

解决方案

经常被忽略的一个权限要求是用户在文件的每个父目录中需要x权限来访问该文件。检查/，/ home，/ home / demo等对www-data x访问的权限。我的猜测是/ home可能是770和www-data不能chdir通过它到任何subdir。如果是，请尝试chmod o + x / home（或任何dir拒绝请求）。

编辑：为了方便地显示路径上的所有权限，使用 namei -om / path / to / check

I have nginx installed with PHP-FPM on a CentOS 5 box, but am struggling to get it to serve any of my files - whether PHP or not.

Nginx is running as www-data:www-data, and the default "Welcome to nginx on EPEL" site (owned by root:root with 644 permissions) loads fine.

The nginx configuration file has an include directive for /etc/nginx/sites-enabled/*.conf, and I have a configuration file example.com.conf, thus:

server {
 listen 80;

 Virtual Host Name
 server_name www.example.com example.com;


 location / {
   root /home/demo/sites/example.com/public_html;
   index index.php index.htm index.html;
 }

 location ~ \.php$ {
  fastcgi_pass   127.0.0.1:9000;
  fastcgi_index  index.php;
  fastcgi_param  PATH_INFO $fastcgi_script_name;
  fastcgi_param  SCRIPT_FILENAME  /home/demo/sites/example.com/public_html$fastcgi_script_name;
  include        fastcgi_params;
 }
}

Despite public_html being owned by www-data:www-data with 2777 file permissions, this site fails to serve any content -

 [error] 4167#0: *4 open() "/home/demo/sites/example.com/public_html/index.html" failed (13: Permission denied), client: XX.XXX.XXX.XX, server: www.example.com, request: "GET /index.html HTTP/1.1", host: "www.example.com"

I've found numerous other posts with users getting 403s from nginx, but most that I have seen involve either more complex setups with Ruby/Passenger (which in the past I've actually succeeded with) or are only receiving errors when the upstream PHP-FPM is involved, so they seem to be of little help.

Have I done something silly here?

解决方案

One permission requirement that is often overlooked is a user needs x permissions in every parent directory of a file to access that file. Check the permissions on /, /home, /home/demo, etc. for www-data x access. My guess is that /home is probably 770 and www-data can't chdir through it to get to any subdir. If it is, try chmod o+x /home (or whatever dir is denying the request).

EDIT: To easily display all the permissions on a path, you can use namei -om /path/to/check
