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
