Centos安装PHP PS：LAMP环境时，为少出错误，先安装一下编译环境
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-developenldap-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
# rpm -qa |greplibxml2
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
yuminstallphp-mcryptlibmcryptlibmcrypt-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
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
