mac下安装 xampp 无法启动apache

1.查看端口是否被占用
sudo lsof -i -n

2.用终端运行xampp，查看具体的错误
sudo su
/Applications/XAMPP/xamppfiles/xampp start

多半是这个问题：
XAMPP: Starting Apache…fail.
XAMPP: Another web server is already running.

解决办法：
sudo apachectl stop
// This command killed Apache server that was pre-installed on MAC OS X.
