将centos 7 默认的 php 5.4升级为 5.6

进入终端后查看php版本

php -v

输出可能如下:

PHP 5.4.35 (cli) (built: Nov 14 2014 07:04:10) Copyright (c) 1997-2014 The PHP Group Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies    with Zend OPcache v7.0.4-dev, Copyright (c) 1999-2015, by Zend Technologies

 

执行下面的命令升级软件仓库

rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

 

执行下面的命令删除php

yum remove php-common

然后像安装那样问你是否继续的,输入yes即可

 

安装php 5.6版本(php56w-devel这个不是必需的)

yum install -y php56w php56w-opcache php56w-xml php56w-mcrypt php56w-gd php56w-devel php56w-mysql php56w-intl php56w-mbstring

 

如果是nginx ,则还需要安装 php56w-fpm

yum install php56w-fpm
