nginx 发现有很多WARN

负载问题，没有完全找到根本的原因，只能从头开始排查

先来瞧哈nginx错误日记 出现了大量（如下所示：）

2012/01/04 16:34:25 [warn] 29939#0: *20552635 an upstream response is buffered to a temporary file /dev/shm/nginx_temp/fastcgi/0001240960 while reading upstream, client: 118.123.13.6, server: www.xxxx.cn, request: "GET /thread-1409108-1-1.html HTTP/1.0", upstream: "fastcgi://unix:/dev/shm/php-fcgi.sock:", host: www.xxx.cn

在nginx.conf 里加入这一段得到解决

fastcgi_buffer_size         512k;
    fastcgi_buffers             6 512k;
    fastcgi_busy_buffers_size   512k;
    fastcgi_temp_file_write_size        512k;
    fastcgi_intercept_errors    on;

这上面的参数根据自己网站页面大小，进行调整
