一直的500 ， 502，受不了吖

早上一起来，又来了，查看vi /usr/local/php/var/log/php-fpm.log

查看php-fpm.conf
pm = dynamic
pm.max_children = 300
pm.start_servers = 80
pm.min_spare_servers = 80
pm.max_spare_servers = 300

貌似设置的够多吖

[root@ wwwlogs]# netstat -anp|grep "php-fpm"|grep "tcp"|grep "pool"|wc -l
119
[root@ wwwlogs]# ps -fe |grep "php-fpm"|grep "pool"|wc -l

安装了memcached，默认配置
启用了opcache，内存缓存256M

500的话可能程序有问题，需要开php错误日志

502置顶帖有说明，建议开php-fpm慢日志结合php-fpm日志和502时间进行排查

慢日志已经开启的，vi /usr/local/php/var/log/slow.log结果为空白。

vi /path/php_error.log，得几个站的错误记录如下：

有的站点内页502，首頁没事，php_error.log也没有报错

licess

看php错误日志内存不足了，无法分配内存了

yanqzh

8G内存，p.php显示有4、5G的空闲内存。

yanqzh

军哥，你好！看回你这个回复，才觉得有深意！

这些天来，此问题一直无法解决。再三看回此帖子，突然想起当初搭建环境时，虽然显示是成功，但是SSH Screen一直没有中断安装环境的会话，而一直停留着，是我ctrl+C强制中断的，当时没有在意，现在回想，确实应该是程序出了问题。

这个情况下，应该怎么办？重新安装环境的话，用完整包吗？当时 是在线安装的，PHP及MYSQL各用什么版本好？PHP貌似只有7.0.19可选

yanqzh

重新安装php是否可行？

licess

和停在安装成功界面没任何关系

没法说哪个版本最好，自行去该程序官网上推荐的php和mysql版本
