20:46:47 [Apache] Problem detected!
20:46:47 [Apache] Port 443 in use by ""D:\Program Files (x86)\VMware\VMware Workstation\vmware-hostd.exe" -u "C:\ProgramData\VMware\hostd\config.xml"" with PID 9168!
20:46:47 [Apache] Apache WILL NOT start without the configured ports free!
20:46:47 [Apache] You need to uninstall/disable/reconfigure the blocking application
20:46:47 [Apache] or reconfigure Apache and the Control Panel to listen on a different port

上面说明VMware占用了443端口

以下通过修改配置文件来修改默认端口（当没有安装VMware不会占用端口）

2.httpd-ssl.conf（修改无效）

3.修改properties.ini

右键记事本打开或notepad++打开properties.ini

[General]

installdir=D:\xampp

base_stack_name=XAMPP

base_stack_version=1.8.3-1

base_stack_platform=windows

require_root_privileges=1

[Apache]

apache_server_port=80

apache_server_ssl_port=443

apache_root_directory=/xampp/apache

apache_htdocs_directory=D:\xampp/htdocs

apache_domainname=127.0.0.1

apache_configuration_directory=D:\xampp/apache/conf

apache_unique_service_name=

[MySQL]

mysql_port=3306

mysql_host=localhost

mysql_root_directory=D:\xampp\mysql

mysql_binary_directory=D:\xampp\mysql\bin

mysql_data_directory=D:\xampp\mysql\data

mysql_arguments=-u root -P3306

mysql_unique_service_name=

[PHP]

php_binary_directory=D:\xampp\php

php_configuration_directory=D:\xampp\php

修改成（默认除apache，禁止修改其他内容，如悉例外）

apache_server_port=8080

apache_server_ssl_port=4433

ctrl+S保存

star

当然也有其他方法，只是有些方法效率不高则不做修改方法
