#tar -zxvf ./eaccelerator-0.9.5-beta2.tar.bz2#cd eaccelerator-0.9.5-beta2#export php_prefix=/usr/local （把php安装目录导入到环境变量，freebsd默认是/usr/local）#$php_prefix/bin/phpize#./configure --enable-eaccelerator=shared --with-php-config=$php_prefix/bin/php-config#make#make install
复制代码
4、ini文件配置安装完成，下面开始配置php.ini文件,eaccelerator提供了两种配置和调用方式，分别如下。安装为 zend extension 模式：
#mkdir /tmp/eaccelerator#chmod 777 /tmp/eaccelerator
复制代码
5、验证安装结果通过浏览器访问您的phpinfo()页面或者运行 php -i 得到php配置信息，里面如果看到类似下面的信息就表示安装成功了。this program makes use of the zend scripting language engine:zend engine v2.1.0, copyright (c) 1998-2006 zend technologies with eaccelerator v0.9.5-beta2, copyright (c) 2004-2006 eaccelerator, by eaccelerator我的机器上同时还安装了zend optimizer3.0.1，所以看到的信息如下：this program makes use of the zend scripting language engine:zend engine v2.1.0, copyright (c) 1998-2006 zend technologies with eaccelerator v0.9.5-beta2, copyright (c) 2004-2006 eaccelerator, by eaccelerator with zend extension manager v1.0.10, copyright (c) 2003-2006, by zend technologies with zend optimizer v3.0.1, copyright (c) 1998-2006, by zend technologies如果你打开了eaccelerator的debug选项，可以从日志中看到类似下面的信息
复制代码
eaccelerator_unlock($key) 根据 $key 释放锁
eaccelerator_cache_output($key, $eval_code, $ttl=0) 将 $eval_code 代码的输出缓存 $ttl 秒，（$ttl参数同 eacclerator_put） 例如：
复制代码
eaccelerator_cache_result($key, $eval_code, $ttl=0) 将 $eval_code 代码的执行结果缓存 $ttl 秒，（$ttl参数同 eacclerator_put），类似 cache_output 例如：
复制代码
eaccelerator_cache_page($key, $ttl=0) 将当前整页缓存 $ttl 秒。 例如：
复制代码
eaccelerator_rm_page($key)删除由 eaccelerator_cache_page() 执行的缓存，参数也是 $key
2、php代码中使用eaccelerator加速测试下eaccelerator强大的威力：（该代码在 cli 模式下可能无效）
pro;
$tt->func();$tt->now(time() + 86400);?>
复制代码
另外，据说在著名的vbulletin 3.60beta版里面已经集成了对eaccelerator的支持。一段来自vbulletin里面的代码
