centos6.8安装php的方法：首先检查当前安装的PHP包并删除；然后重新配置安装包源；接着通过“yum -y install php56w.x86_64”执行安装；最后安装PHP FPM即可。

检查当前安装的PHP包

yum list installed | grep php

如果有安装的PHP包，先删除他们, 如:

yum remove php.x86_64 php-cli.x86_64 php-common.x86_64

配置安装包源:

# Centos 5.Xrpm -Uvh http://mirror.webtatic.com/yum/el5/latest.rpm# CentOs 6.xrpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm# CentOs 7.Xrpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpmrpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

如果想删除上面安装的包，重新安装

rpm -qa | grep webstaticrpm -e  [上面搜索到的包即可]

执行安装

yum -y install php56w.x86_64yum -y --enablerepo=webtatic install php56w-develyum -y install php56w-pdo php56w-xml php56w-gd php56w-gd.x86_64 php56w-ldap.x86_64 php56w-mbstring.x86_64 php56w-mcrypt.x86_64 php56w-mysql.x86_64 php56w-pdo.x86_64 php56w-opcache.x86_64

安装PHP FPM

yum -y install php56w-fpm#设置php-fpm开机启动chkconfig php-fpm on#启动php-fpm/etc/init.d/php-fpm start

注：如果想更换到php5.5或5.4版本, 直接把上面的56w换成55w或者54w就可以了
