/etc/php-fpm.d/www.conf 配置注意事项

1、php-fpm 配置文件里 rlimit_files的值要与系统的打开连接数一致

1）查看系统文件打开连接数

[root@iZ94eveq0q4Z ~]# ulimit -n
65535

2）查看一下php-fpm 配置文件里 rlimit_files的值

; Set open file descriptor rlimit#rlimit设置打开的文件描述符
; Default Value: system defined value
rlimit_files = 65535
如果两个值不一样，则要设置为一样

方法如下：

3）设置系统打开文件连接数

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

设置好后重启php-fpm服务

2、 request_terminate_timeout = 0 设置为0

; 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 = 0

因为这个参数会直接杀掉php进程，然后重启php进程，这样前端nginx就会返回104: Connection reset by peer。这个过程是很慢，总体感觉就是网站很卡

nginx可能出现502
recv() failed (104: Connection reset by peer) while reading response header from upstream

3、request_slowlog_timeout这个配置不要开启

之前服务器上开始了这个参数，并且设置如下：

request_slowlog_timeout = 10导致图片处理每次都失败，每次都是502错误。

错误信息如下：

Nginx的错误信息：
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的错误信息为：

所以最好是要这个设置给屏蔽掉。
;request_slowlog_timeout = 10
