ubuntu – WordPress没有使用Nginx php-fpm和其他问题调整图像大小

Ubuntu 前端之家
前端之家收集整理的这篇文章主要介绍了ubuntu – WordPress没有使用Nginx php-fpm和其他问题调整图像大小，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
最近我为我们的Ubuntu LoCo团队的wordpress博客设置了一个带512mb / 1ghz cpu的Ubuntu 12.04 VPS,Nginx PHP-fpm Varnish APC Percona的 MySQL服务器CloudFlare Pro.博客每天点击大约3~4k,使用大约180MB和8~20％的cpu.一切似乎都疯狂地工作……页面加载非常好,比我们的任何竞争对手快16倍……但是有一个问题.

当我们上传图片时,wordpress不会调整它的大小,所以我们只能在帖子中插入完整的图像.如果图像有,比方说30kb,它调整大小…但如果图像有100kb,它不会……

在Nginx错误日志中,我看到：

upstream timed out (110: Connection timed out) while reading response header from upstream,client: 150.162.216.64,server: www.ubuntubrsc.com,request: "POST /wp-admin/async-upload.PHP HTTP/1.1",upstream: "fastcgi://unix:/var/run/PHP5-fpm.sock:",host: "www.ubuntubrsc.com",referrer: "http://www.ubuntubrsc.com/wp-admin/media-upload.PHP?post_id=2668&"

它似乎与这个问题有关,但我不知道.当超时发生时,我也开始尝试查看帖子了：

upstream timed out (110: Connection timed out) while reading response header from upstream,request: "GET /tutoriais-gimp-6-adicionando-aplicando-novos-pinceis.html HTTP/1.1",referrer: "http://www.ubuntubrsc.com/"

只有重启PHP5-fpm修复它.

我尝试增加一些超时和东西,但它没有用,所以我想这是一种我还没想到的限制.有人可以帮我吗,拜托？

如果我使用W3 Total Cache的页面缓存(磁盘增强),我也开始在首页出现404错误.它工作得很好,直到某一天,然后,无处不在,它开始发生.今晚我将禁用我的移动插件并仅激活W3 Total Cache以查看它是否与他们发生冲突…

为了完成所有这些,我得到了这个错误：

PHP Warning:  apc_store(): Unable to allocate memory for pool. in /var/www/wp-content/plugins/w3-total-cache/lib/W3/Cache/Apc.PHP on line 41

我已经修改了我的APC设置,但没有成功.那么……有人可以帮我解决这些问题吗？

哦……如果有帮助的话,我会像这样安装PHP：

sudo apt-get install PHP5-fpm PHP5-suhosin PHP-apc PHP5-gd PHP5-imagick PHP5-curl

和来自官方PPA的Nginx.抱歉我的英文不好,谢谢你们的时间！ (：

该错误表明PHP后端无法以合理的时间范围进行回复.虽然你对PHP-fpm没有直接限制,但max_execution_time和max_input_time是我的第一个猜测.
