用eAccelerator为PHP加速 eAccelerator配置和使用指南
时间：2016-04-05对于本文中出现的错误导致您的损失，Michael不承担责任。
前一段时间完成了服务器从FreeBSD4.10到6.1的升级，同时把PHP也升级到了最新的PHP5.1.4，Apache也升级到了最新的Apache2.2，为了更好的提高系统的性能，考虑对PHP再进行一些优化，前两年接触过MMCache和eAccelerator，尤其对eAccelerator非常喜欢，这次优化也选择了它，下面整理一些文档和大家分享。

一、eAccelerator介绍
1、背景
eAccelerator 是一个免费开源的PHP加速、优化、编译和动态缓存的项目，它可以通过缓存PHP代码编译后的结果来提高PHP脚本的性能，使得一向很复杂和离我们很远的PHP脚本编译问题完全得到解决。通过使用eAccelerator，可以优化你的PHP代码执行速度，降低服务器负载，可以提高PHP应用执行速度最高达10倍。
eAccelerator 项目诞生于2004年，当时它是作为 Turck MMCache 项目的一个分支提出并投入开发的。 Turck MMCache 由 Dmitry Stogov 开发，是个非常优秀的PHP内存缓存加速系统，如今仍然有很大部分 eAccelerator 的代码应用到该项目中，目前该项目有很长时间没有更新了，对于最新的PHP5.x的支持还未推出。
2、原理
eAccelerator 通过把经过编译后的PHP代码缓存到共享内存中，并在用户访问的时候直接调用从而起到高效的加速作用。它的效率非常高，从创建共享内存到查找编译后的代码都在非常短的时间内完成，对于不能缓存到共享内存中的文件和代码，eAccelerator还可以把他们缓存到系统磁盘上。
eAccelerator 同样还支持PHP代码的编译和解释执行，你可以通过encoder.php脚本来对php代码进行编译达到保护代码的目的，经过编译后的代码必须运行在安装了eAccelerator的环境下。eAccelerator编译后的代码不能被反编译，它不象其他一些编译工具那样可以进行反编译，这将使得代码更加安全和高效。
二、eAccelerator安装配置
1、支持平台
由于aAccelerator提供了大部分基于共享内存的API，所以在*nix的平台上将得到更好的支持，虽然也发布了基于windows平台的binary版本，但我在这里就只提供基于*nix平台的配置和说明，目前可以支持的平台包括Linux, FreeBSD, OpenBSD, Mac OS X, Solaris, AIX en HP-UX。
2、系统要求
php4 or php5
autoconf
automake
libtool
m4
eAccelerator 只支持使用 mod_php 或者 fastcgi mode 安装的PHP
3、安装
先去eAccelerator官方下载最新版的源码包：eaccelerator-0.9.5-beta.tar.bz2
#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
#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
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：
zend_extension="/usr/local/lib/php/20050922/eaccelerator.so"
eaccelerator.shm_size="16"
eaccelerator.cache_dir="/tmp/eaccelerator"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.log_file = "/var/log/httpd/eaccelerator_log"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
eaccelerator.shm_size="16"
eaccelerator.cache_dir="/tmp/eaccelerator"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.log_file = "/var/log/httpd/eaccelerator_log"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
如果你使用了thread safe模式安装的PHP，你必须使用 “zend_extension_ts” 替换第一行的 “zend_extension”.
安装为 PHP extension 模式：（这是大部分采用的方式）
extension="eaccelerator.so"
eaccelerator.shm_size="16"
eaccelerator.cache_dir="/tmp/eaccelerator"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.log_file = "/var/log/httpd/eaccelerator_log"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
eaccelerator.shm_size="16"
eaccelerator.cache_dir="/tmp/eaccelerator"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.log_file = "/var/log/httpd/eaccelerator_log"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
有关php.ini文件的详细配置说明，请参照源码目录的README文档或者访问官方文档：ini setting
完成安装配置后，我们最后要创建缓存目录
#mkdir /tmp/eaccelerator
#chmod 777 /tmp/eaccelerator
#chmod 777 /tmp/eaccelerator
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

Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies

我的机器上同时还安装了Zend Optimizer3.0.1，所以看到的信息如下：

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
#tail /var/log/httpd/eAccelerator_log
EACCELERATOR hit: "/var/www/toplee.com/blog/index.php"
EACCELERATOR hit: "/var/www/toplee.com/blog/wp-blog-header.php"
EACCELERATOR hit: "/var/www/toplee.com/blog/wp-config.php"
EACCELERATOR hit: "/var/www/toplee.com/blog/wp-settings.php"
EACCELERATOR hit: "/var/www/toplee.com/blog/wp-content/plugins/wp-cache/wp-cache-phase1.php"
...
EACCELERATOR hit: "/var/www/toplee.com/blog/index.php"
EACCELERATOR hit: "/var/www/toplee.com/blog/wp-blog-header.php"
EACCELERATOR hit: "/var/www/toplee.com/blog/wp-config.php"
EACCELERATOR hit: "/var/www/toplee.com/blog/wp-settings.php"
EACCELERATOR hit: "/var/www/toplee.com/blog/wp-content/plugins/wp-cache/wp-cache-phase1.php"
...
以上信息表示文件都得到了缓存和命中。
至此，我们就完成了全部的安装和配置，好好享受eAccelerator带给你的惊喜吧，根据Michael的测试，效果的确相当的好。
#p#副标题#e#三、在PHP中可以使用eAccelerator的API开发
1、API和文档说明：
eAccelerator提供了便捷便捷而又稳定的本机缓存实现方式，由于大部分代码实现基于共享内存，所以只能在*nix平台中使用，Windows平台Michael就暂时不知道何时有这方面的支持了。
eAccelerator提供如下的API接口和文件：（下述文件均在源码包的doc/php/目录下）
文件列表：
cache.php
dasm.php

void eaccelerator_rm_page (string $key)
boolean eaccelerator_set_session_handlers ()
boolean eaccelerator_unlock (string $key)
有关上述文档详细说明请参考官方文档：API Documents
下面有部分网友翻译后的接口说明：
eaccelerator_put($key, $value, $ttl=0)
将 $value 以 $key 为键名存进缓存(php4下支持对像类型，看源码好像zend2里不支持了)，$ttl 是这个缓存的生命周期，单位是秒，省略该参数或指定为 0 表示不限时，直到服务器重启清空为止。
eaccelerator_get($key)
根据 $key 从缓存中返回相应的 eaccelerator_put() 存进去的数据，如果这项缓存已经过期或不存在那么返回值是 NULL
eaccelerator_rm($key)
根据 $key 移除缓存
eaccelerator_gc()
移除清理所有已过期的 key
eaccelerator_lock($key)
为 $key 加上锁定操作，以保证多进程多线程操作时数据的同步。需要调用 eaccelerator_unlock($key) 来释放这个锁或等待程序请求结束时自动释放这个锁。
例如:
<?php
eaccelerator_lock("count");
eaccelerator_put("count",eaccelerator_get("count")+1));
?>
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：
<?php eaccelerator_cache_output('test', 'echo time(); phpinfo();', 30); ?>
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：
<?php eaccelerator_cache_result('test', ' time() . "Hello";', 30); ?>
eaccelerator_cache_page($key, $ttl=0)
将当前整页缓存 $ttl 秒。
例如：
<?php
eaccelerator_cache_page($_SERVER['PHP_SELF'].'?GET='.serialize($_GET),30);
echo time();
phpinfo();
?>
eaccelerator_rm_page($key)
删除由 eaccelerator_cache_page() 执行的缓存，参数也是 $key
将 $value 以 $key 为键名存进缓存(php4下支持对像类型，看源码好像zend2里不支持了)，$ttl 是这个缓存的生命周期，单位是秒，省略该参数或指定为 0 表示不限时，直到服务器重启清空为止。
eaccelerator_get($key)
根据 $key 从缓存中返回相应的 eaccelerator_put() 存进去的数据，如果这项缓存已经过期或不存在那么返回值是 NULL
eaccelerator_rm($key)
根据 $key 移除缓存
eaccelerator_gc()
移除清理所有已过期的 key
eaccelerator_lock($key)
为 $key 加上锁定操作，以保证多进程多线程操作时数据的同步。需要调用 eaccelerator_unlock($key) 来释放这个锁或等待程序请求结束时自动释放这个锁。
例如:
<?php
eaccelerator_lock("count");
eaccelerator_put("count",eaccelerator_get("count")+1));
?>
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：
<?php eaccelerator_cache_output('test', 'echo time(); phpinfo();', 30); ?>
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：
<?php eaccelerator_cache_result('test', ' time() . "Hello";', 30); ?>
eaccelerator_cache_page($key, $ttl=0)
将当前整页缓存 $ttl 秒。
例如：
<?php
eaccelerator_cache_page($_SERVER['PHP_SELF'].'?GET='.serialize($_GET),30);
echo time();
phpinfo();
?>
eaccelerator_rm_page($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
下面有一个测试的代码，你可以测试一下eAccelerator强大的威力：（该代码在 cli 模式下可能无效）
<?php
class test_cache {
var $pro = 'hello';
function test_cache() {
echo "Object Created!<br>\n";
}
function func() {
echo ', the world!';
}
function now($t) {
echo date('Y-m-d H:i:s', $t);
}
}
$tt = eaccelerator_get("test_tt");
if (!$tt)
{
$tt = new test_cache;
eaccelerator_put("test_tt", $tt);
echo "no cached!<br>\n";
}
else {
echo "cached<br>\n";
}
echo $tt->pro;
$tt->func();
$tt->now(time() + 86400);
?>
class test_cache {
var $pro = 'hello';
function test_cache() {
echo "Object Created!<br>\n";
}
function func() {
echo ', the world!';
}
function now($t) {
echo date('Y-m-d H:i:s', $t);
}
}
$tt = eaccelerator_get("test_tt");
if (!$tt)
{
$tt = new test_cache;
eaccelerator_put("test_tt", $tt);
echo "no cached!<br>\n";
}
else {
echo "cached<br>\n";
}
echo $tt->pro;
$tt->func();
$tt->now(time() + 86400);
?>
另外，据说在著名的vBulletin 3.60Beta版里面已经集成了对eAccelerator的支持，下面是一段来自vBulletin里面的代码
