php扩展模块eAccelerator,mysql_pdo,memcache安装配置
基本环境约定:1.CentOS5.8 x86_64位 采用最小化安装，系统经过了基本优化篇
2.mysql安装路径:/usr/local/mysql
3.源码包存放位置：/home/oldboy/tools
4.源码包编译安装位置：/application
如果你清楚lanp环境搭建,参考以下文章:
A.php和apache编译安装方法
B.mysql5.1编译方法和步骤
一.PHP扩展安装实验安装环境
1.检查对应的版本
cat /etc/redhat-release
uname -m
/application/apache/bin/apachectl -v
/application/php/bin/php -v
mysqladmin -uroot -pmybaby3306 -S /data/3306/mysql.sock "version"
2.准备环境
# cat /etc/redhat-release
CentOS release 5.10 (Final)
# uname -m

二.功能和加速模块安装
1.eAccelerator加速模块,是一个自由开放源码php加速器，优化和动态内容缓存，提高了php脚本的缓存性能，使得PHP脚本在编译的状态下，对服务器的开销几乎完全消除。 它还有对脚本起优化作用，以加快其执行效率。使您的PHP程序代码执效率能提高1-10倍。
2.用到命令:
cd /home/oldboy/tools/
tar xzf eaccelerator-eaccelerator-42067ac.tar.gz
cd eaccelerator-eaccelerator-42067ac
/application/php/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=/application/php/bin/php-config
make && make install
3.安装过PDO扩展为PHP访问数据库定义了一个轻量级的、一致性的接口，它提供了一个数据访问抽象层，这样，无论使用什么数据库，都可以通过一致的函数执行查询和获取数据。PDO随PHP5.1发行，在PHP5.0的PECL扩展中也可以使用，无法运行于之前的PHP版本。程

三.memcache安装
1.介绍:
Memcache是一个高性能的分布式的内存对象缓存系统，通过在内存里维护一个统一的巨大的hash表，它能够用来存储各种格式的数据，包括图像、视频、文件以及数据库检索的结果等。简单的说就是将数据调用到内存中，然后从内存中读取，从而大大提高读取速度。
2.安装命令:
cd /home/oldboy/tools/
wget http://www.memcached.org/files/memcached-1.4.17.tar.gz
tar zxf memcached-1.4.17.tar.gz
cd memcached-1.4.17
./configure --with-php-config=/application/php/bin/php-config
make && make install
3.安装过程:
# wget http://pecl.php.net/get/memcache-2.2.7.tgz

四.动态添加功能模块pdo_mysql
1.介绍:PDO扩展为PHP访问数据库定义了一个轻量级的、一致性的接口，它提供了一个数据访问抽象层，这样，无论使用什么数据库，都可以通过一致的函数执行查询和获取数据。PDO随PHP5.1发行，在PHP5.0的PECL扩展中也可以使用，无法运行于之前的PHP版本。
2.用到命令:
cd /home/oldboy/tools/
wget http://pecl.php.net/get/PDO_MYSQL-1.0.2.tgz
tar xzf PDO_MYSQL-1.0.2.tgz
cd PDO_MYSQL-1.0.2
./configure --with-php-config=/application/php/bin/php-config \
--with-pdo-mysql=/usr/local/mysql/
make && make install
注.下载/PDO_MYSQL-1.0.3.tgz未安装成功,make时提示:

五.功能模块:imagemagick安装
1.imagemagick介绍:
mageMagick是一套功能强大、稳定而且开源的工具集和开发包，可以用来读、写和处理超过89种基本格式的图片文件，包括流行的TIFF、JPEG、GIF、 PNG、PDF以及PhotoCD等格式。利用ImageMagick，你可以根据web应用程序的需要动态生成图片, 还可以对一个（或一组）图片进行改变大小、旋转、锐化、减色或增加特效等操作，并将操作的结果以相同格式或其它格式保存，对图片的操作，即可以通过命令行进行，也可以用C/C++、Perl、Java、PHP、Python或Ruby编程来完成。同时ImageMagick提供了一个高质量的2D工具包，部分支持SVG。ImageMagic的主要精力集中在性能，减少bug以及提供稳定的API和ABI上。
2.安装命令
cd /home/oldboy/tools/
wget http://www.imagemagick.org/download/ImageMagick-6.8.9-9.tar.gz
tar xzf ImageMagick-6.8.9-9.tar.gz
cd ImageMagick-6.8.9-9
./configure
make
make install
#装模块,要建立在上一步安装imagemagick软件的基础上
wget http://pecl.php.net/get/imagick-3.1.2.tgz
tar xzf imagick-3.1.2.tgz
cd imagick-3.1.2
/application/php/bin/phpize
./configure --with-php-config=/application/php/bin/php-config
make
make install
ll /application/php5.3.29/lib/php/extensions/no-debug-zts-20090626/
3.安装过程:
# cd /home/oldboy/tools/

-rwxr-xr-x 1 root root135439 Oct 27 21:50 pdo_mysql.so
六.配置以上模块
1.修改php.ini
sed -i 's#; extension_dir = "./"#extension=/application/php5.3.29/lib/php/extensions/no-debug-zts-20090626/#g' php.ini
vi php.ini +1000,添加如下模块
extension=memcache.so
extension=pdo_mysql.so
extension=imagick.so
extension=eaccelerator.so
2.配置参数:
cat >> /application/php/lib/php.ini<<EOF
extension=eaccelerator.so
eaccelerator.shm_size="64"
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="3600"
eaccelerator.shm_prune_period="3600"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
EOF
七.phpize介绍:
1. 安装php（fastcgi模式）的时候，常常有这样一句命令：/usr/local/webserver/php/bin/phpize
phpize是用来扩展php扩展模块的，通过phpize可以建立php的外挂模块
比如你想在原来编译好的php中加入memcached或者ImageMagick等扩展模块，可以使用phpize，通过以下几步工作。
当php编译完成后，php的bin目录下会有phpize这个脚本文件。在编译你要添加的扩展模块之前，执行以下phpize就可以了；
