请大神帮忙看看这到底咋回事，预缓存问题。

gamer 发表于 2016-2-28 17:29:55

不能不说lnmp环境性能的确出众，我是从wdcp转到lnmp的，一用就舍不得丢了。
不过有个问题就是预缓存。我用的是wordpress 插件wp-super-cache的预缓存功能。

环境：之前在Linode vpsCentOS 6.5 64位 wdcp环境， wordpress插件wp-super-cache的预缓存功能一切正常。
现在转到阿里云ecs CentOS 6.5 64位军哥lnmp一键包环境，其它都正常就wp-super-cache的预缓存不正常。
现象：比如指定120分钟预缓存一次网站全部内容，时间到了后缓存页面开始工作。问题来了，只缓存几十个页面后自动停止了，一直显示定在那里不缓存了。只有等下一次的120分钟到来，又开始接着上次的id缓存剩下的页面，又缓存几十个页面又停止了。

请问这是这么回事，是不是lnmp环境里哪里的设置需要修改？？

不清楚具体原因，你php是什么版本

开慢日志和php错误日志看看

gamer 发表于 2016-2-28 21:05:34

现在用的 php 4.4.40以前用的是5.3的

错误日志好像就一个 nginx_error.log 25日的

这个不是php-fpm的错误日志，这是nginx日志，只是说了php-fpm可能挂掉了

军哥我看了看php-fpm.conf里的设置是不是跟这里面的设置有关？

pm.max_children = 10
是不是跟这个子进程数量有关？设小了？？

回复 6# 的帖子

上面日志只有wp-cron执行超时的信息，可以增加超时时间或设为0不限制试试，置顶帖502排查解决方法里有具体修改方法

谢了军哥

我试试
