《PHP實(shí)戰(zhàn)：/etc/php-fpm.d/www.conf 配置注意事項(xiàng)》要點(diǎn)：
本文介紹了PHP實(shí)戰(zhàn)：/etc/php-fpm.d/www.conf 配置注意事項(xiàng)，希望對(duì)您有用。如果有疑問，可以聯(lián)系我們。

1、php-fpm 配置文件里 rlimit_files的值 要與系統(tǒng)的打開連接數(shù)一致PHP教程

1)查看系統(tǒng)文件打開連接數(shù)PHP教程

[root@iZ94eveq0q4Z ~]# ulimit -n
65535PHP教程

2)查看一下php-fpm 配置文件里 rlimit_files的值 PHP教程

; Set open file descriptor rlimit#rlimit設(shè)置打開的文件描述符
; Default Value: system defined value
rlimit_files = 65535
如果兩個(gè)值不一樣,則要設(shè)置為一樣PHP教程

方法如下：PHP教程

3)設(shè)置系統(tǒng)打開文件連接數(shù)PHP教程

[root@hotdata ~]# ulimit -HSn 65535
[root@hotdata ~]# ulimit -n
65535
[root@hotdata ~]#PHP教程

設(shè)置好后重啟php-fpm服務(wù)PHP教程

2、 request_terminate_timeout = 0 設(shè)置為0PHP教程

; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the ‘max_execution_time' ini option
; does not stop script execution for some reason. A value of '0′ means ‘off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
request_terminate_timeout = 0PHP教程

因?yàn)檫@個(gè)參數(shù)會(huì)直接殺掉php進(jìn)程,然后重啟php進(jìn)程,這樣前端nginx就會(huì)返回104: Connection reset by peer.這個(gè)過程是很慢,總體感覺就是網(wǎng)站很卡PHP教程

nginx可能出現(xiàn)502
recv() failed (104: Connection reset by peer) while reading response header from upstreamPHP教程

3、request_slowlog_timeout這個(gè)配置不要開啟PHP教程

之前服務(wù)器上開始了這個(gè)參數(shù),并且設(shè)置如下：PHP教程

request_slowlog_timeout = 10導(dǎo)致圖片處理每次都失敗,每次都是502錯(cuò)誤.PHP教程

錯(cuò)誤信息如下：PHP教程

Nginx的錯(cuò)誤信息：
2015/12/28 16:20:23 [error] 649#0: *9862 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 163.177.69.13,

php-fpm的錯(cuò)誤信息為：

所以最好是要這個(gè)設(shè)置給屏蔽掉.
;request_slowlog_timeout = 10PHP教程
