军哥大神，求助：关于php-fpm问题， 动态页面一直出现502

Wention

问下，为何非要有php-fpm这个步骤？优化来优化去，还是那个样，真的很蛋疼，来来去去还是502错误

VPS是LINODE，1GRAM 1CPU

现在设置这样
[global]
pid = /usr/local/php/var/run/php-fpm.pid
error_log = /usr/local/php/var/log/php-fpm.log
log_level = notice
[www]
listen = /tmp/php-cgi.sock
listen.backlog = -1
listen.allowed_clients = 127.0.0.1
listen.owner = www
listen.group = www
listen.mode = 0666
user = www
group = www
pm = dynamic
pm.max_children = 16
pm.start_servers = 2
pm.min_spare_servers = 16
pm.max_spare_servers = 16
request_terminate_timeout = 300
request_slowlog_timeout = 20
slowlog = var/log/slow.log

很蛋疼，各位大神，如何解决呢？？？？？？？？？？？

Wention

要么得重启php-fpm要么得重启mysql，也是醉了

Wention

顶上去给大神看下，求大神解救，拜谢

licess

只看这个日志，你再phpmyadmin里导入数据时超时了，这个很正常，php都是有超时时间的，如想用这个方法按置顶帖502排查方法修改执行时间

最简单的方法就是mysql命令导入：https://www.vpser.net/manage/mysql-import-export.html

Wention

但是我不是导入的啊，都用一段时间了啊

licess

你的php-fpm的日志就那几条

你这慢日志好几万条没法，有具体的502的时段没

Wention

那我再上传下php-fpm的日志吧，，时间段就是白天动态页面都会502或者打开卡的不要不要的，晚上一过12点就很流畅，早上6点开始就开始了

大部分都是提示这个，找这个两个文件，排查提示的函数看看

Wention

问题解决了一半了，主要是我开了百度云的CDN，所以导致后台和动态文件被缓存，现在用360CDN好多了，不过采集和后台生成的话，就会卡死502
