升级现有PHP版本
1.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
2.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
3.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
4.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
5.重启httpd
service httpd restart
查看最新的版本
php -v
现在应该是5.6了!
