Mac升级到php7
使用homebrew安装php7
brew update #更新源
brew search php #查找源中的php，发现有php7.1版本，安装最新的php7.1
brew install php71
安装完之后
php -v
localhost:promotion wyc$ php-fpm -v
PHP 5.5.36 (fpm-fcgi) (built: May 29 2016 01:07:24)
Copyright (c) 1997-2015 The PHP Group
Zend Engine v2.5.0, Copyright (c) 1998-2015 Zend Technologies
发现仍然是mac自带的php5.5
which php #显示可执行文件在/usr/bin/php,而我们暗转的php7在/usr/local/bin/php
php和php-fpm分别在/usr/local/bin/和/usr/local/sbin,在shell中将会按照path的顺序依次寻找，所以讲/usr/local/sbin:/usr/local/bin加到path的头部就好，加到尾部，则还是寻找到/usr/bin下面的可执行文件
echo $PATH #/usr/bin:/bin:/usr/sbin:/sbin
vi ~/.bash_profile
写入：export PATH="/usr/local/sbin:$PATH"
source ~/.bash_profile
这是加入到用户变量里面，可以加入到系统变量里面，vi /etc/paths 然后添加自己的变量
再次运行php -v 和php-fpm -v
PHP 7.1.5 (cli) (built: May 23 2017 11:45:41) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies
显示的就是新版本的php

安装redis拓展
mac不能通过brew安装redis拓展，所以可以通过源码安装。centos同样也可以这样：https://www.cnblogs.com/mentalidade/p/9658132.html
