我在 Debian Squeeze 下将 php 5.3 更新到 5.4。之后我尝试安装 OPcache，这就是我所做的：
apt-get install build-essential php5-dev unzip
cd /usr/src
wget https://github.com/zend-dev/ZendOptimizerPlus/archive/master.zip
unzip master.zip
cd /usr/src/ZendOptimizerPlus-master
phpize
./configure
make
make test
make install
vi /etc/php5/conf.d/opcache.ini
;zend_extension=/usr/lib/php5/20100525/opcache.so ;PHP 5.4 can't use this, file not exist on my server
zend_extension=/usr/lib/php5/20090626/opcache.so ;PHP 5.3 got only this one (?)
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=8000
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.enable_cli=1
/etc/init.d/apache2 restart
php -v
Zend OPcache requires Zend Engine API version 220090626.
The Zend Engine API version 220100525 which is installed, is newer.
Contact Zend Technologies at http://www.zend.com/ for a later version of Zend OPcache.

我做错了什么？“phpize”给了我这个：
Configuring for:
PHP Api Version: 20090626
Zend Module Api No: 20090626
Zend Extension Api No: 220090626
这不应该是：20100525 和 PHP 5.4 吗？
请帮忙！
