php开启慢日志

浏览数：45 / 时间：2015年06月09日

默认是以本机的安装路径

cd /usr/local/php/etc/

vim php-fpm.conf

; The log file for slow requests
; Default Value: not set
; Note: slowlog is mandatory if request_slowlog_timeout is set
slowlog = log/pool.log.slow   //可以修改慢日志的路径

; 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 = 1   //慢日志超时的时间

不过目录需要手动创建，不然重启php-fpm将会出错

mkdir /usr/local/php/log

php-fpm慢日志的例子，慢日志会记录下进程号，脚本名称，具体哪个文件哪行代码的哪个函数执行时间过长。
