启用 php-fpm 的 slow log 日志，查看执行时间过长的php文件，并将执行时间过长的进程直接终止掉！看看效果如何！
具体操作方法也简单，就修改一个文件，执行命令：# vi /usr/local/php/etc/php-fpm.conf
PHP 5.3.3 之前版本设置如下：
The timeout (in seconds) for serving a single request after which the worker process will be terminated
Should be used when 'max_execution_time' ini option does not stop script execution for some reason
'0s' means 'off'
request_terminate_timeout">10s
The timeout (in seconds) for serving of single request after which a php backtrace will be dumped to slow.log file
'0s' means 'off'
request_slowlog_timeout">1s
The log file for slow requests
logs/slow.log
PHP 5.3.3 之后版本设置如下：
; The timeout for serving a single request after which a PHP backtrace will be
; dumped to the 'slowlog' file. A value of '0s' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
request_slowlog_timeout = 1s (对执行时间超过1s的php脚本进行日志记录)
; The log file for slow requests
; Default Value: /usr/local/php/var/log/php-fpm.log.slow
slowlog = /usr/local/php/var/log/php-fpm.log.slow (开启慢执行日志，日志目录路径一定要正确存在，否则会报错)
; 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 = 30s (当php脚本执行时间超过30秒后终止该php脚本)
注：request_terminate_timeout 将执行时间太长的进程直接终止
request_slowlog_timeout 将执行过慢的文件写入日志
以后即可根据慢执行日志 /usr/local/php/var/log/slow.log 来优化程序文件了！
