1、停用MAC自带的apache
sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist 2>/dev/null

2、安装httpd
brew install httpd //如果之前有安装执行重装 brew reinstall httpd

3、安装php72
brew install php72 --with-httpd

4、为了可以切换php，建立软链接
ln -s /usr/local/opt/php/lib/httpd/modules/libphp7.so /usr/local/lib/libphp7.so

5、修改apache配置
sudo vim /usr/local/etc/httpd/httpd.conf

ServerName localhost
DocumentRoot "/Users/mac/data"
<Directory "/Users/mac/data">
...
AllowOverride All
...

#LoadModule php5_module /usr/local/php5-5.6.29-20170114-210819/libphp5.so
#LoadModule php7_module /usr/local/opt/php/lib/httpd/modules/libphp7.so

#Brew PHP LoadModule for sphp switcher
#LoadModule php5_module /usr/local/lib/libphp5.so
LoadModule php7_module /usr/local/lib/libphp7.so

<IfModule dir_module>
DirectoryIndex index.php index.html
</IfModule>

<FilesMatch .php$>
SetHandler application/x-httpd-php
</FilesMatch>

6、再后面就是建立虚拟站点本地域名
打开httpd-vhost.conf这一句。或加上：Include /usr/local/etc/httpd/extra/httpd-vhosts.conf
把原来的httpd-vhost.conf拷贝到新位置下：
cp /etc/apache2/extra/httpd-vhosts.conf /usr/local/etc/httpd/extra/httpd-vhosts.conf
