Opcache – 加速PHP利器，查看opcache状态的方法 - WBB

Opcache是php的加速器，5.3以前为APC，5.3以后边位opcache+apcu，5.5之后系统内置opcache（未确认）

之前一直忽略了这个利器，最近在做新项目，用ab测了下发现效果还是蛮强悍的，特别是有高并发需求的网站

本站加速前ab测试：

安装方式

yum install php-opcache

本站适用remi-php源安的php5.6 所以是 yum install php-opcache --enablerepo=remi-php56

装完重启php/lighttpd即生效。

运行状态

查看opcache状态的单文件： https://github.com/rlerdorf/opcache-status， 3年没更新了，但功能强悍，看看内存占用什么的还是足够用的，方便调整数值。

直接下载： https://raw.githubusercontent.com/rlerdorf/opcache-status/master/opcache.php

没法上github？
