解决方法参考：http://www.wopus.org/wordpress-basic/getting-started/2536.html

安装启动apache报错：
Error: Apache shutdown unexpectedly.
This may be due to a blocked port, missing dependencies,
improper privileges, a crash, or a shutdown by another method.

原因是：Apache常用端口，http和https的端口被占用

处理：
1，XAMPP的控制面板，点击Apache的Config
2，打开 Apache(httpd.conf)
找到：Listen 80 替换成：Listen 8080；找到：ServerName localhost:80 替换成：ServerName localhost:8080；保存。
3，打开Apache(httpd-ssl.conf)
找到：Listen 443 替换成：Listen 4433；
找到：ServerName localhost:443 替换成：ServerName localhost:4433；保存。
4，关闭XAMPP，重新启动Apache。
