最近上传图片和发表内容比较多的文章都会出现500的错误提示。
php程序在第一句exit也出错，看来问题不是出现在php，而是nginx
看看nginx的错误日志

2011/02/10 21:14:00 [crit] 9504#0: *204 open() "/Data/apps/nginx/fastcgi_temp/6/02/0000000026" failed (13: Permission denied) while reading upstream, client: 67.195.115.28, server: aslibra.com, request: "GET /blog/ HTTP/1.0", upstream: "fastcgi://127.0.0.1:9000", host: "www.aslibra.com"

这个是出错的地方，显然是读写缓存的问题，大的请求需要临时目录的读写。
权限修改了也没有用，很奇怪，加了如下几个定义就好了，可以参考：

  client_header_timeout 120;
  client_max_body_size 10m;
  client_body_buffer_size 256k;

  proxy_buffer_size 4k;
  proxy_buffers 8 32k;
  proxy_busy_buffers_size 64k;
  proxy_temp_file_write_size 64k;

第一段除了上传文件的大小必须外，可能影响不大，关键是第二段。
