yum源默认的版本太低了,手动安装有一些麻烦,想采用Yum更新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_64

2、更换rpm源

···

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 https://mirror.webtatic.com/yum/el7/epel-release.rpm
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 webstatic
rpm -e 上面搜索到的包即可

3.运行yum install

···
php5.5
yum 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_64

php5.6
yum 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

php7.0
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_64
···

4.安装PHP FPM
···
yum install php55w-fpm
yum install php56w-fpm
yum install php70w-fpm
systemctl enable php-fpm.service【开机自启动】
···

本次更新升级PHP版本即可完成!
