nginx 报错 upstream timed out (110: Connection timed out)解决方案

error.log报错如下：

2013/05/18 21:21:36 [error] 11618#0: *324911 upstream timed out (110: Connection timed out) while reading response header from upstream, 
client: 42.62.37.56, server: localhost, request: "GET /code-snippet/2747/HTML5-Canvas-usage HTTP/1.0", 
upstream: "fastcgi://127.0.0.1:9002", host: "outofmemory.cn", referrer: "http://outofmemory.cn/code-snippet/tagged/canvas"

报这个错误之后，整个服务器就不响应了，但是nginx后面的webpy程序没有任何错误，后端的数据库也很正常，从网上查了很多资料，都是说要修改proxy_read_timeout,proxy_send_timeout和proxy_buffer几个相关设置的值。

如下配置，要放在server或者http配置节之内

large_client_header_buffers 4 16k;
client_max_body_size 30m;
client_body_buffer_size 128k;
#proxy_connect_timeout 300;
#proxy_read_timeout 300;
#proxy_send_timeout 300;
#proxy_buffer_size 64k;
#proxy_buffers   4 32k;
#proxy_busy_buffers_size 64k;
#proxy_temp_file_write_size 64k;

fastcgi_connect_timeout 300;
fastcgi_read_timeout 300;
fastcgi_send_timeout 300;
fastcgi_buffer_size 64k;
fastcgi_buffers   4 32k;
fastcgi_busy_buffers_size 64k;
fastcgi_temp_file_write_size 64k;

你可以看到上面是proxy_和fastcgi_两种配置，就是说如果你的nginx后面是proxy，就设置proxy相关的配置，如果是fastcgi就设置fastcgi相关的配置。

现在暂时服务器没报错了，坐等下一次报错

续：现在只看到

 [warn] 12483#0: *1472 a client request body is buffered to a temporary file /www/wdlinux/nginx-1.0.12/client_body_temp/0000000001, client: 119.188.35.16, server: www.shejiqun.com, request: "POST /Designer-saveLoad-tuku-1.html HTTP/1.1", host: "www.shejiqun.com"

nginx php解析过慢
