vps主机安装配置php强化模块eaccelerator

环境：centos5

确保系统已经安装好php-devel、autoconf、automake、m4、libtool、 gcc(预编译用） make(编译用）等软件，可使用rpm -q 软件包名查看，如未安装，使用yum -y install 软件包名进行安装。

eaccelerator官方网站：http://eaccelerator.net/

安装配置步骤如下：

1）下载源码包：本地下载地址：

# cd /usr/local/src

# wget http://bart.eaccelerator.net/source/0.9.5.3/eaccelerator-0.9.5.3.zip

2）解压源码包

# unzip eaccelerator-0.9.5.3.zip

#cd eaccelerator-0.9.5.3

3)利用phpize进行php程序的预处理

#phpize

4）预编译设置：

#./configure --enable-eaccelerator=shared --with-php-config=/usr/bin/php-config

5）编译：

# make

6）编译成功后安装

# make install

此时这个新编译的模块会被放置到/usr/lib/php/modules/eaccelerator.so中

7）修改php.ini和预先加载PHP模块

vi /etc/php.ini

按shift+g键跳到配置文件的最末尾，加上以下配置信息：

[eaccelerator]
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.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″

预先加载php模块

#vi /etc/ld.so.conf

#ldconfig <–把模块导入高速缓存

在文件尾添加

/usr/lib/php/modules

8)建立eaccelerator的暂存数据

mkdir /tmp/eaccelerator
chmod 0777 /tmp/eaccelerator

9）使用ab命令测试一下网站效率，如下：

[root@www tmp]# ab -dkS -n100 -c100 http://localhost/phpinfo.php

10）重新apache

# apachectl restart

11）验证eAccelerator是否生效

在命令行下运行

#php -v

如果输出想如下的信息

[root@www tmp]# php -v
PHP 5.1.6 (cli) (built: Jul 16 2008 19:53:00)
Copyright (c) 1997-2006 The PHP Group

   with eAccelerator v0.9.5.3, Copyright (c) 2004-2006 eAccelerator, by eAccelerator
[root@www tmp]#

证明已经加载成功，且生效

12）重新使用ab命令测试一下网站效率，如下：

[root@www tmp]# ab -dkS -n100 -c100 http://localhost/phpinfo.php

13)总结，从第9和第12的Time taken for tests:项目，可以看出，加载eAccelerator后效率提高了快1倍。
