过程不表，都比较顺利

参考如下URL：

http://www.lvtao.net/server/ZendOpcache.html

大家知道目前PHP的缓存插件一般有三个：APC、eAccelerator、XCache，但未来它们可能都会消失，因为PHP 5.5已经集成ZendOpcache，功能和前三者相似但又有少许不同，缓存速度据说比它们更快（注意：只是据说，我没测试过）。

这几个PHP加速插件的主要原理都相同，就是把PHP执行后的数据缓冲到内存中从而避免重复的编译过程，能够直接使用缓冲区已编译的代码从而提高速度，降低服务器负载，它们的效率是显而易见的，像drupal这种庞大的CMS，每次打开一个页面要调用数十个PHP文件，执行数万行代码，效率可想而知，在安 装APC等加速器后打开页面的速度明显加快。

Zend Opcache 已经集成在了PHP 5.5里面，编译安装PHP5.5的时候加上--enable-opcache就行了。但也支持低版本的 PHP 5.2.*, 5.3.*, 5.4.*，未来会取消对5.2的支持，下面是我在PHP 5.4下的安装方法：
官方网站：http://pecl.php.net/package/ZendOpcache
依次执行下面的命令

  1. wget http://pecl.php.net/get/zendopcache-7.0.3.tgz
  2. tar xzf zendopcache-7.0.3.tgz
  3. cd zendopcache-7.0.3
  4. phpize
  5. ###如果找不到phpize 的话自己找PHP路径，我的在/usr/local/php/bin/phpize，下面这行也要按你的php.ini路径自行修改
  6. ./configure --with-php-config=/usr/local/php/bin/php-config
  7. make
  8. make install

如果显示Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-zts-20100525/ 表示安装完成，下面要修改php的配置文件让它生效

在 php.ini 的最后面加入下面几行

[Opcache]

  1. zend_extension=/usr/local/php/lib/php/extensions/no-debug-zts-20100525/opcache.so
  2. opcache.memory_consumption=128
  3. opcache.interned_strings_buffer=8
  4. opcache.max_accelerated_files=4000
  5. opcache.revalidate_freq=60
  6. opcache.fast_shutdown=1
  7. opcache.enable_cli=1

128意思是给它分配128M内存，然后重启apache，用phpinfo查看是否生效，显示下面的信息就说明生效了

统计的脚本如下：

  3. OCP - Opcache Control Panel (aka Zend Optimizer+ Control Panel for PHP)
  4. Author: _ck_ (with contributions by GK, stasilok)
  5. Version: 0.1.6
  6. Free for any kind of use or modification, I am not responsible for anything, please share your improvements
  7.  
  8. * revision history
  9. 0.1.6 2013-04-12 moved meta to footer so graphs can be higher and reduce clutter
  10. 0.1.5 2013-04-12 added graphs to visualize cache state, please report any browser/style bugs
  11. 0.1.4 2013-04-09 added "recheck" to update files when using large revalidate_freq (or validate_timestamps=Off)
  12. 0.1.3 2013-03-30 show host and php version, can bookmark with hashtag ie. #statistics - needs new layout asap
  13. 0.1.2 2013-03-25 show optimization levels, number formatting, support for start_time in 7.0.2
  14. 0.1.1 2013-03-18 today Zend completely renamed Optimizer+ to OPcache, adjusted OCP to keep working
  15. 0.1.0 2013-03-17 added group/sort indicators, replaced "accelerator_" functions with "opcache_"
  16. 0.0.6 2013-03-16 transition support as Zend renames product and functions for PHP 5.5 (stasilok)
  17. 0.0.5 2013-03-10 added refresh button (GK)
  18. 0.0.4 2013-02-18 added file grouping and sorting (click on headers) - code needs cleanup but gets the job done
  19. 0.0.2 2013-02-14 first public release
  20.  
  21. * known problems/limitations:
  22. Unlike APC, the Zend OPcache API
  23. - cannot determine when a file was put into the cache
  24. - cannot change settings on the fly
  25. - cannot protect opcache functions by restricting execution to only specific scripts/paths
  26.  
  27. * todo:
  28. Extract variables for prefered ordering and better layout instead of just dumping into tables
  29. File list filter
