一、 PHP加速器介绍

PHP加速器是一个为了提高PHP执行效率从而缓存起PHP的操作码这样PHP后面执行就不用解析转换了可以直接调用PHP操作码这样速度上就提高了不少。

Apache中使用mod_php的请求、响应执行流程

1、Apache接收请求。

2、Apache传递请求给mod_php。

3、mod_php定位磁盘文件并加载到内存中。

4、mod_php编译源代码成为opcode树。

5、mod_php执行opcode树。

PHP加速器相应的就是第四步它的目的就是防止PHP每次请求都重复编译PHP代码因为在高访问量的网站上大量的编译往往没有执行速度快呢所以这里面有个瓶颈就是PHP的重复编译既影响了速度又加载了服务器负载为了解决此问题 PHP加速器就这样诞生了。

二、 PHP加速器安装与配置

1、安装配置APC

APC全称是Alternative PHP Cache,官方翻译叫”可选PHP缓存”,它是PHP PECL中的一个扩展好像是f acebook在使用它下面开始安装ubuntu环境 

$wget

$tar xvzf APC-3.0.19. tgz

$cd APC-3.0.19/APC-3.0.19

$/usr/local/php/bin/phpize

$./conf igure –enable-apc –enable-apc-mmap –wi th-php-config=/usr/local/php/bin/php-config

$make

$sudo make install

下面我们再配置APC,因为我的PECL扩展路径改变了所以我得移动下编译好的文件

$sudo mv /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/apc.so /usr/local/php/lib/php/extensions/PECL

然后我们再编辑php. i n i文件进行配置请把下面的代码加入到php. i n i中即可extension_dir = "/usr/local/php/lib/php/extensions/PECL"extension =apc.so

; APCapc.enabled = 1apc.shm_segment s = 1apc.shm_size =64apc.optimization = 1apc.num_=0apc.ttl =0apc.gc_ttl = 3600apc.cache_by_defaul t =on

这样重启apache就会在php info()信息中显示。

2、安装配置eAccelerator

eAcce lera tor的前身其实是t ruck-mmcache 因为开发t ruk-mmcache的人被Zend给招安了所以开发eAccelerator的人继承了truk-mmcache的一些特性设计出eAccelerator加速器。安装如下

$wget

$tar -jxf eaccelerator-0.9.5. tar.bz2

$cd eaccelerator-0.9.5

$/usr/local/php/bin/phpize

$./configure –enable-eaccelerator=shared –with-php-config=/usr/local/php/bin/php-config

$make

$sudo make install

$sudo mv /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so /usr/local/php/lib/php/extensions/PECL

将下面代码加入php. i n i文件中extension =eaccelerator.so

; eAcceleratoreaccelerator.shm_size = "16"eaccelerator.cache_dir = "/tmp/eaccelerator"eaccelerator.enable = "1"eaccelerator.optimizer = "1"eaccelerator.check_mtime = "1"eaccelerator.debug = "0"eaccelerator.fi lter = ""eaccelerator.shm_max = "0"eaccelerator.shm_ttl = "0"eaccelerator.prune_period = "0"eaccelerator.shm_only = "0"eaccelerator.compress = "1"eaccelerator.compress_level = "9"

创建缓存目录,重启apache

$sudo mkdir /tmp/eaccelerator

$sudo chmod 777 /tmp/eaccelerator

$sudo /usr/local/apache/apachectl restart

在php in fo()检查是否安装成功.

3、安装配置XCac h e

XCach e作为国人自己开发的东西做小菜鸟的我也感到骄傲而且XCach e无论在速度还是性能上都做的不错。下面就赶紧让我们品尝它吧

$wget

$tar xvzf xcache-1 .2.2. tar.gz

$cd xcache-1 .2.2

$/usr/local/php/bin/phpize

$./conf igure –enable-xcache –enable-xcache-coverager –with-php-config=/usr/local/php/php-config

$make

$sudo make install

$sudo mv /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/xcache.so /usr/local/php/lib/php/extensions/PECL

在php. i n i添加配置信息extension =xcache.so

; xcachexcache.admin.user = "admin"xcache.admin.pass = "(执行) echo ’(你的密码)’ |md5sum(得出的密文)"

;xcache.size =24Mxcache.shm_scheme = "mmap"xcache.count =2xcache.slots = 8kxcache. ttl =0xcache.gc_interval =0xcache.var_size = 8Mxcache.var_count = 1xcache.var_slots = 8kxcache.var_ttl =0xcache.var_maxtt l =0xcache.var_gc_interval = 300xcache. tes t =Offxcache.readonly_protection =Onxcache.mmap_path = "/tmp/xcache"xcache.coredump_directory = ""xcache.cacher =Onxcache.stat =Onxcache.optimizer =Off

;xcache.coverager =Onxcache.coveragedump_directory = ""

创建缓存目录重启apache

$sudo mkdir /tmp/xcache

$sudo chmod 777 /tmp/xcache

$sudo /usr/local/apache/bin/apachectl restart

去查看php in fo()信息吧

三、 PHP加速器测试

1、测试环境

3、结果摘要

四、 PHP加速器比较结果总结

1、通过测试得出eAccelerator在请求时间和内存占用综合方面是最好的。

2、通过测试得出使用加速器比无加速器在请求时间快了3倍左右。

3、通过各个官方观察XCac h e是更新最快的这也说明最有发展的。
