发布日期：2022-08-08 09:21 | 文章来源：源码中国

在access.log中有大量400错误,并以每天几百M的速度增加,占用大量空间.

复制代码代码如下:

tail -f /opt/nginx/logs/access.log

网上大把的文章说是HTTP头/Cookie过大引起的,可以修改nginx.conf中两参数来修正.

复制代码代码如下:

 client_header_buffer_size 16k;
 large_client_header_buffers 4 32k;

修改后

复制代码代码如下:

 client_header_buffer_size 64k;
 large_client_header_buffers 4 64k;

没有效果,就算我把nginx0.7.62升到最新的0.8.54也没能解决.
在官方论坛中nginx作者提到空主机头不会返回自定义的状态码,是返回400错误.
http://forum.nginx.org/read.php?2,9695,11560

最后修正如下
改为原先的值

复制代码代码如下:

 client_header_buffer_size 16k;
 large_client_header_buffers 4 32k;

关闭默认主机的日志记录就可以解决问题

复制代码代码如下:

 server {
 listen *:80 default;
 server_name _;
 return 444;
 access_log off;
 }
