简介：
在CentOS上安装PHP7安装环境及版本：
系统环境：CentOS Linux release 7.5.1804 (Core)为了便于测试验证，提前安装好apache，并将发布目录定位/var/www/html，具体参考《Apache安装》一、PHP7 Yum安装
1.1 准备
如果是安装系统自带的默认版本，如下命令即可
yum install php
yum install php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt1.2 设置PHP的搜索位置
安装PHP7，先设置搜索位置
