opcache，php自身集成的缓存功能。由于我的系统是ubuntu server系统，所以在安装的时候很简单，直接apt-get install 方式安装的php，而且安装的是php5.5的版本，所以系统是自带opcache的，不需要我们再重新安装。
接下来要配置一下opcache
sudo vi /etc/php5/fpm/conf.d ; configuration for php ZendOpcache module ; priority=05 ;zend_extension=opcache.so opcache.enable=1 opcache.save_comments=1 opcache.memory_consumption=512 opcache.interned_strings_buffer=8 opcache.max_accelerated_files=4000 opcache.revalidate_freq=60 opcache.fast_shutdown=1 opcache.enable_cli=1 opcode.caching=1 opcache.force_restart_timeout=3600 opcache.optimization_level=0xffffffff opcache.optimization=1 opcache.use_cwd=0 opcache.revalidate_path=0 opcache.enable_file_override=0
然后修改php.ini文件，在最后添加一行zend_extension=opcache.so
重启php-fpm或者是nginx，我们可以看到在phpinfo的界面出现了zend opcache的配置信息
好了，到这里我们的opcache已经开始启用了。当然，在上面配置中，可以在php.ini中不加最后一行内容，但是在opcache的配置文件中要把注释去掉，也可以。
现在看起来还是很别扭，我们可以通过直观的图表形式展现出来
好吧，没发过附件，无法上传，好像格式不对，直接上代码吧，网上也有很多的，可以自行百度。

OCP - Opcache Control Panel (aka Zend Optimizer+ Control Panel for PHP)
Author: _ck_ (with contributions by GK, stasilok)
Version: 0.1.6
Free for any kind of use or modification, I am not responsible for anything, please share your improvements
* revision history
0.1.6 2013-04-12 moved meta to footer so graphs can be higher and reduce clutter
0.1.5 2013-04-12 added graphs to visualize cache state, please report any browser/style bugs
0.1.4 2013-04-09 added "recheck" to update files when using large revalidate_freq (or validate_timestamps=Off)
0.1.3 2013-03-30 show host and php version, can bookmark with hashtag ie. #statistics - needs new layout asap
0.1.2 2013-03-25 show optimization levels, number formatting, support for start_time in 7.0.2
0.1.1 2013-03-18 today Zend completely renamed Optimizer+ to OPcache, adjusted OCP to keep working
0.1.0 2013-03-17 added group/sort indicators, replaced "accelerator_" functions with "opcache_"
0.0.6 2013-03-16 transition support as Zend renames product and functions for PHP 5.5 (stasilok)
0.0.5 2013-03-10 added refresh button (GK)
0.0.4 2013-02-18 added file grouping and sorting (click on headers) - code needs cleanup but gets the job done
0.0.2 2013-02-14 first public release
* known problems/limitations:
Unlike APC, the Zend OPcache API
- cannot determine when a file was put into the cache
- cannot change settings on the fly
- cannot protect opcache functions by restricting execution to only specific scripts/paths
* todo:
Extract variables for prefered ordering and better layout instead of just dumping into tables
File list filter
