Linux安装PHP7.X
下载PHP安装包并上传到服务器（新建一个文件夹用来存放）
1.安装PHP依赖
yum install gcc libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel
2.开始安装PHP
解压安装包
tar -zxf php-7.0.30.tar进入目录
cd php-7.0.30
复制编译代码
Apache使用非源码编译需要在安装httpd-devel包，否则会缺失aoxs文件夹

make && make install编译完成之后，需要添加PHP命令到环境变量里
vi /etc/profile在文件末尾加入并保存：
PATH=$PATH:/usr/local/php/php/7.0.30/bin
export PATH要使改动立即生效执行
source /etc/profile查看PHP 版本
