下面安装PHP时数显很多问题，为了减少问题，直接安装先yum一下
yum -y install gcc pcre pcre-devel gcc-c++ autoconf libxml2 libxml2-devel zlib zlib-devel glibc libjpeg libjpeg-devel libpng libpng-devel glibc-devel glib2 glib2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel openssl openssl-devel openldap openldap-devel openldap-clients openldap-servers make cmake freetype-devel
1、下载
php官方下载地址: http://www.php.net/downloads.php 此处下载版本：php-5.6.7
cd /usr/local/src //进入目录
tar -zxvf php-5.6.7 //解压
cd php-5.6.7 //进入文件目录
# ./configure --prefix=/usr/local/php --with-config-file-path=/etc --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql --with-mysqli --with-libxml-dir --with-png-dir --with-jpeg-dir --with-freetype-dir --with-gd --with-zlib-dir --with-mcrypt --enable-soap --enable-mbstring=all --enable-sockets --enable-ftp --enable-zip --with-gettext
错误：configure: error: xml2-config not found. Please check your libxml2 installation
[root@XKWB3403 php-5.3.8]# rpm -qa |grep libxml2 libxml2-2.6.26-2.1.12 libxml2-python-2.6.26-2.1.12 重新安装libxml2和libxml2-devel包 yum install libxml2 yum install libxml2-devel -y
错误：mcrypt.h not found. Please reinstall libmcrypt
解决办法一 1、安装第三方yum源 yum install epel-release sh ./atomic 2、使用yum命令安装 yum install php-mcrypt libmcrypt libmcrypt-devel 解决办法二、 使用php mcrypt 前必须先安装Libmcrypt libmcrypt源码安装方法： cd /usr/local/src wget http://softlayer.dl.sourceforge.net/sourceforge/mcrypt/libmcrypt-2.5.8.tar.gz tar -zxvf libmcrypt-2.5.8.tar.gz cd /usr/local/src/libmcrypt-2.5.8 ./configure --prefix=/usr/local make make install

make && make install
echo $?
#设置环境变量 vi /etc/profile #在末尾添加以下内容 PATH=/usr/local/php/bin:$PATH export PATH #让刚才的修改生效 source /etc/profile
#复制配置文件到etc目录 cp /usr/src/php-5.6.7/php.ini-production /etc/php.ini
#修改默认时区
vim /etc/php.ini
date.timezone =Asia/Shanghai
此处要做以说明，由于前面安装Apache2.4时候没有指定配置文件，所以/etc/没有http目录，因此下文中的方法需要改进：
#让httpd支持php解析 vim /etc/httpd/httpd.conf #找到这行 AddType application/x-gzip .gz .tgz #添加这一句 AddType application/x-httpd-php .php #找到以下这句，在后面添加index.php DirectoryIndex index.html DirectoryIndex index.html index.php
改进方法：
mkdir /etc/httpd/ //创建httpd目录 cd /etc/httpd ln -s /usr/local/apache2/conf/httpd.conf . //创建软链接文件，方便修改
vim /etc/httpd/httpd.conf
#找到这行
AddType application/x-gzip .gz .tgz
#添加这一句
AddType application/x-httpd-php .php
#找到以下这句，在后面添加index.php
DirectoryIndex index.html
DirectoryIndex index.html index.php
至此PHP安装成功
测试PHP
touch /usr/local/apache2/htdocs/test.php vim /usr/local/apache2/htdocs/test.php
写入 <?php phpinfo(); ?>
浏览器输入 "IP"/test.php 出现以下内容即为成功
