一、环境准备（lamp环境:linux+apache+php+mysql)
1、安装php之前，首先要检查一下相关lib库
rpm -qa zlib libxml libjpeg freetype libpng gd curl libiconv zlib-devel libxml2-devel libjpeg-devel freetype-devel libpng-devel gd-devel curl-devel
如果没有安装的，要安装上 yum install zlib libxml libjpeg freetype libpng gd curl libiconv zlib-devel libxml2-devel libjpeg-devel freetype-devel libpng-devel gd-devel curl-devel
yum install openssl-devel -y
yum install libxslt-devel -y
2、安装libiconv,下载安装包libiconv-1.14.tar.gz，
安装
tar zxvf libiconv-1.14.tar.gz
cd libiconv-1.14
./configure --prefix=/usr/local/libiconv
make
make install
3、安装好apache和mysql
二、安装php
1、下载安装包php-5.3.27.tar.gz
2、解压并进入目录
tar zxvf php-5.3.27.tar.gz
cd php-5.3.27
3、安装
编译
./configure \
--prefix=/application/php5.3.27 \ php安装路径
--with-apxs2=/application/apache/bin/apxs \ apache下的apxs路径，通过apxs增加php扩展模块到apache中
--with-mysql=/application/mysql \ mysql安装路径
--with-xmlrpc \
--with-openssl \
--with-zlib \
--with-freetype-dir \
--with-gd \
--with-jpeg-dir \
--with-png-dir \
--with-iconv=/usr/local/libiconv \
--enable-short-tags \
--enable-sockets \
--enable-zend-multibyte \
--enable-soap \
--enable-mbstring \
--enable-static \
--enable-gd-native-ttf \
--with-curl \
--with-xsl \
--enable-ftp \
--with-libxml-dir
编译完成后，make && make install
4、创建链接
ln -s /application/php5.3.27/ /application/php
5、检查
安装后，查看/application/apache/modules/ ，可以看到由apxs将php模块插入apache中
并且在apache配置文件中，也有相关配置
完成
