方法一：
yum 安装
默认的版本太低了，手动安装有一些麻烦，想采用Yum安装的可以使用下面的方案：1.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 yum remove php.x86_64 php-cli.x86_64 php-common.x86_64 php-gd.x86_64 php-ldap.x86_64 php-mbstring.x86_64 php-mcrypt.x86_64 php-mysql.x86_64 php-pdo.x86_642.Centos 5.X rpm -Uvh http://mirror.webtatic.com/yum/el5/latest.rpm CentOs 6.x rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm CentOs 7.X rpm -Uvh rpm -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3.运行yum installyum install php55w.x86_64 php55w-cli.x86_64 php55w-common.x86_64 php55w-gd.x86_64 php55w-ldap.x86_64 php55w-mbstring.x86_64 php55w-mcrypt.x86_64 php55w-mysql.x86_64 php55w-pdo.x86_64yum install php56w.x86_64 php56w-cli.x86_64 php56w-common.x86_64 php56w-gd.x86_64 php56w-ldap.x86_64 php56w-mbstring.x86_64 php56w-mcrypt.x86_64 php56w-mysql.x86_64 php56w-pdo.x86_64注：如果想升级到5.6把上面的55w换成56w就可以了。yum install php70w.x86_64 php70w-cli.x86_64 php70w-common.x86_64 php70w-gd.x86_64 php70w-ldap.x86_64 php70w-mbstring.x86_64 php70w-mcrypt.x86_64 php70w-mysql.x86_64 php70w-pdo.x86_644.安装PHP FPMyum install php55w-fpm yum install php56w-fpm yum install php70w-fpm |
