使用 fcgiwrap 的 nginx 上的 Python - 在从上游读取响应 header 时上游过早关闭 FastCGI stdout

Question

我正在尝试让一个 hello world python 脚本在我的 nginx 网络服务器上运行。当我尝试加载 URI 时收到“502 Bad Gateway”错误: http://sub.dom.com/py-bin/hello.py

这是我的 nginx 错误日志中的错误。

2013/04/27 13:54:14 [error] 14158#0: *1 upstream closed prematurely FastCGI stdout while reading response header from upstream,
client: w.x.y.z, server: sub.dom.com, request: "GET /py-bin/hello.py HTTP/1.1", upstream: "fastcgi://unix:/var/run/fcgiwrap.socket:", host: "sub.dom.com"

py-bin 位置:/home/cluber/www/sub.dom.com/py-bin

public_html 的位置:/home/cluber/www/sub.dom.com/public_html

hello.py 的位置:/home/cluber/www/sub.dom.com/py-bin/hello.py (chmod 777)

fastcgi_params的位置:/etc/nginx/fastcgi_params

nginx 配置的内容

server {
    server_name sub.dom.com;
    access_log /home/cluber/www/sub.dom.com/logs/access.log;
    error_log /home/cluber/www/sub.dom.com/logs/error.log;

        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
    }
    location ~ ^/py-bin/.*\.py$ {
        gzip off;
        root /home/cluber/www/sub.dom.com;
        fastcgi_pass unix:/var/run/fcgiwrap.socket;
        fastcgi_index index.py;
        include fastcgi_params;
    }
}

fastcgi_params 的内容

fastcgi_param   QUERY_STRING            $query_string;
fastcgi_param   REQUEST_METHOD          $request_method;
fastcgi_param   CONTENT_TYPE            $content_type;
fastcgi_param   CONTENT_LENGTH          $content_length;

fastcgi_param   SCRIPT_FILENAME         $request_filename;
fastcgi_param   SCRIPT_NAME             $fastcgi_script_name;
fastcgi_param   REQUEST_URI             $request_uri;

fastcgi_param   SERVER_NAME             $server_name;

fastcgi_param   HTTPS                   $https;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param   REDIRECT_STATUS         200;

socks 的位置:

ls /var/run | grep sock
fcgiwrap.socket
php5-fpm.sock

hello.py 的内容

#!/usr/bin/python

print "Content-type: text/html\n\n"
print "Hello world"

请注意，PHP 工作正常。

Answer 1

尝试将响应代码(“HTTP/1.0 200 OK”)添加到 hello.py 输出的顶部，如下所示:

#!/usr/bin/python

print "HTTP/1.0 200 OK"
print "Content-type: text/html\n\n"
print ""
print "Hello world"
