域名正常运行一段时间后会 400 bad request PHP文件无法执行，静态文件可以访问，然后执行php重启就恢复正常。过一段时间又这样。 amh4.2 版本。 服务器128G内存，24核。 虚拟主机PHP-FPM 当前设置为动态1,50,300,300 （静态和ondemand 都设置过） ------------------------- http://amh.sh/bbs/post-669-1-1.htm 用这个方法试过不行。 ------------------------- memory_limit 设置10240M 也不行 ------------------------- 设置过计划任务重启PHP 和 nginx 也不行。 服务器的负载主要是外部访问和自己访问自己，执行PHP文件。 同服务器中的其他域名都正常。负载主要是来自会自动400 bad request 的那个域名。 nginx 测试结果 # /usr/local/nginx/sbin/nginx -t nginx: [emerg] directive "rewrite" is not terminated by ";" in /usr/local/nginx/conf/rewrite/phpcms.conf:7 nginx: configuration file /usr/local/nginx/conf/nginx.conf test failed 下面是重启Nginx的结果 ============================================================= [LNMP/Nginx] Amysql Host - AMH 4.2 http://Amysql.com [OK] Nginx stop ============================================================= [LNMP/Nginx] Amysql Host - AMH 4.2 http://Amysql.com Shutting down MySQL...

-ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n 查看了下。观察了一段时间发现自己服务器的IP的访问量有 700-6000之间。 使用CURL的访问应该是非常快速的，不知道为什么访问会一直滞留下来。 目前已经修改掉程序，观察中。

你试试从下面几个方面调试 （你的机器配置来看，几乎可以忽略机器性能导致的问题）
1. request header过大所引起，request过大，通常是由于cookie中写入了较大的值所引起。 在nginx.conf中，将client_header_buffer_size和large_client_header_buffers都调大，可缓解此问题。 其中主要配置是client_header_buffer_size这一项，默认是1k，所以header小于1k的话是不会出现问题的。 2. 看看 error log， 看出现 400 的时候，有没下面的错误 XXXXXXXX upstream sent too big header while reading response header from upstream XXXXX 把 proxy_buffer_size 调大 试试看 3. 有些时候也许是个人自己的浏览器导致的（清除浏览器的cookie应能解决）。 如果你的电脑碰到 400， 试试在其他电脑打开网站看看。

当然，从你发出来的log，可以看到 php-fpm 有些配置不是正确，例如下面的，最好都相应调整好
pm.min_spare_servers(5) and pm.max_spare_servers(900) cannot be greater than pm.max_children(99)

域名正常运行一段时间后会 400 bad request
