在Nginx 日誌中發現很多 http 1.0 499 的錯誤!

沒人遇到過這個問題嗎?現在又出現這個問題了,每天早上都會有一個小時,這三天以來!

暈，我也遇到一樣的問題，環境基本相同，也是Nginx + PHP FastCGI，這兩天早上總有一段時間狂報499錯誤，用
netstat -anpo | grep "php-cgi" | wc -l

查看使用緊的進程數，居然比平常多出2~3倍，CPU幾乎耗盡，也是大概1個小時后就變回正常，不知何因。。。

我的也是這個問題，當時看到網上有說是配置文件和啟動文件不一致導致的，可沒發現我的配置哪裡有不一致的

如果前端沒有問題,請詳細分析一下後端是否有問題

回復 #1 myfreeke 的帖子

呵呵...非得回復你這個,今天我遇到的問題跟你差不多哦,我花了很長時間才找到答案.錯誤跟你報的一樣,但沒看你的php-fpm.conf,所以也只能把我的解決方法寫在這裡.

這個rlimit_nofile的問題,和系統最大文件數有關,
1:ulimit -n
XXX
看看系統當前文件打開最大值為XXX
2:cat php-fpm.conf | grep rlimit
<value name="rlimit_files">XXX</value>

這兩個值一定要一樣.否則就會出上面日誌的錯誤.

回復 #6 很溫暖 的帖子

感謝你的回復,我的這二個參數是配置的最大值,65535

後來也是這二個參數解決了這個問題,但是資料庫也有問題,我1K的資料庫連接一到高峰馬上用完,后採用DZ添加memcached的功能來解決所有問題

你的配置是不是有問題?你的伺服器內存多大,PHP-CGI開多少個進程,NGINX開多少個?

1.修改系統文件描述符數目
修改
/etc/security/limits.conf
加上
*        soft    nofile  65535
*        hard    nofile  65535

2.修改php-fpm 設置
修改 /usr/local/webserver/php/etc/php-fpm.conf
<value name="rlimit_files">65535</value>

<value name="max_requests">10000</value>

<value name="log_level">warn</value>


<value name="request_slowlog_timeout">5s</value>

3.重新登陸session,重啟php-fpm，使得新設置生效。
文件描述符數目 php-fpm reload不會生效，所以用 php-fpm restart
/usr/local/webserver/php/sbin/php-fpm restart

可以試試spawn-fcgi 1.6.2   已經獨立成一個程序了   不用給php打補丁就能使用   經長期使用穩定性還不錯
