检察php-fpm设置途径
root@ubuntu:/home/tb# ps -ef |grep fpm root 1642 1 0 10:17 ? 00:00:01 php-fpm: master process (/etc/php/7.0/fpm/php-fpm.conf) www-data 3685 1642 0 17:14 ? 00:00:04 php-fpm: pool www www-data 3686 1642 0 17:14 ? 00:00:03 php-fpm: pool www www-data 3808 1642 0 17:43 ? 00:00:03 php-fpm: pool www root 3930 2208 0 18:10 pts/0 00:00:00 grep --color=auto fpm root@ubuntu:/home/tb#
php-fpm.conf的末了一行动
include=/etc/php/7.0/fpm/pool.d/*.conf
那我们去那边改www.conf，检察关于慢查询的引见
314 ; The log file for slow requests 315 ; Default Value: not set 316 ; Note: slowlog is mandatory if request_slowlog_timeout is set 317 ;slowlog = log/$pool.log.slow 318 319 ; The timeout for serving a single request after which a PHP backtrace will be 320 ; dumped to the 'slowlog' file. A value of '0s' means 'off'. 321 ; Available units: s(econds)(default), m(inutes), h(ours), or d(ays) 322 ; Default Value: 0 323 ;request_slowlog_timeout = 0
增加两行设置
slowlog=/var/log/php7.0/fpm/slow.log request_slowlog_timeout=1s
重启fpm，同时注重目次权限等平常题目
service php7.0-fpm reload
检察log回显效果

关于log的申明
[03-Jan-2018 18:48:53] [pool www] pid 4931
这个没啥诠释，时候历程id
script_filename = /usr/share/nginx/ testapp/index.php
实行剧本称号，php web运用都为单进口
[0x00007fb626213520] session_start() /usr/share/nginx/ testapp/app/models/user_model.php:11
这个第三行比较主要：是客栈顶部信息（is the top of the stack trace），他申明指出了超出了阈值的当前实行的要领的函数挪用是哪一个，以及细致的文件及代码行数
剩下的其他部份就是 挪用的递次（从下往上，终究致使变慢超时的效果）
其他申明
假如发明第三行是以相似curl_exec()，比方：这平常是收集io占用了时候，假如是必需要求第三方，那末。。忍吧。
[0x00007fb6262136f0] curl_exec() /usr/share/nginx/
一样，假如有mysql_query之类的，也是因为sql 慢查询致使的
