有人可以帮我，我每隔几秒就会收到 502 错误网关

该服务器在具有四核和 3g ram 的 debian 上的 vps 上运行

这是我可以在 nginx 日志中出现的错误类型：

2012/07/23 15:06:53 [错误] 2908#0: *247 recv() 在从上游读取响应标头时失败（104：对等方重置连接），客户端：81.255.98.253，服务器：www.acmslt。 fr，请求：“GET /category/culte/conferences/HTTP/1.1”，上游：“fastcgi://127.0.0.1:9000”，主机：“acmslt.fr”，引用者：“http://www.google .fr/url?sa=t&rct=j&q=mosqu%C3%A9e​​%20de%20savigny%20le%20temple%2077&source=web&cd=2&ved=0CFsQjBAwAQ&url=http%3A%2F%2Facmslt.fr%2Fcategory%2Fculte%2Fconferences%2F&ei =OzANUOj0HYrG0QXusf2xCg&usg=AFQjCNHxw6lN8eBnkEOYDh5ONmutLiATHA" ~ 这里是 nginx.conf

user www-data;
worker_processes 4;
events {
        worker_connections 1024;
       }

http {
     include mime.types;
     default_type application/octet-stream;

     # Hide the Nginx version number
     server_tokens off;

     # Tweeks
     sendfile on;
     tcp_nodelay off;
     tcp_nopush on;
     keepalive_timeout 5;
     client_body_timeout 10;
     client_header_timeout 10;
     send_timeout 10;
     client_max_body_size 8M;

     set_real_ip_from 127.0.0.1;
     real_ip_header X-Forwarded-For;

     gzip on;
     gzip_disable "MSIE [1-6].(?!.*SV1)";
     gzip_vary on;
     gzip_comp_level 3;
     gzip_proxied any;
     gzip_buffers 16 8k;

     include /etc/nginx/conf.d/*.conf;
     include /etc/nginx/sites-enabled/*;
  }

可用网站中的网站conf

server {
        listen 8080;
        server_name www.acmslt.fr acmslt.fr;
        location / {
        root /var/www/wordpress;
        index index.php index.html index.htm;
        # Rewrite rules
        if (!-e $request_filename) {
        rewrite ^(.+)$ /index.php?q=$1 last;
       }
       # Security
       # include global/security.conf;
       # W3 Total Cache
       include global/wordpress-w3-total-cache.conf;
       # PHP-FPM
       include global/php-fpm.conf;
       }
}

然后是 global/php-fpm.conf

# PHP scripts -> PHP-FPM server listening on 127.0.0.1:9000
location ~ \.php$ {
                   fastcgi_pass 127.0.0.1:9000;
                   fastcgi_index index.php;
                   include fastcgi_params;
                   fastcgi_connect_timeout 60;
                   fastcgi_send_timeout 180;
                   fastcgi_read_timeout 600;
                   fastcgi_temp_file_write_size 1M;
                   fastcgi_intercept_errors on;
                   fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                  }

php-fpm www.conf

[www]
user = www-data
group = www-data
listen = 127.0.0.1:9000
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
chdir = /

谢谢

编辑这里是我可以在 php-fpm.log 中看到的

这是我在 php-fpm 日志中看到的内容
