1、下载XAMPP
官方主页：https://www.apachefriends.org/index.html
2、安装
（安装提示：重要！ 由于激活用户帐户控制(uac)在您的系统的一些XAMPP的功能可能是限制。使用UAC请避免将XAMPP安装到C：程序文件(x86)(缺少写的权限)。在此设置后，或与系统配置实用程序禁用UAC。）
Important! Because an activated User Account Control (UAC) on your sytem some functions of XAMPP are possibly restricted. With UAC please avoid to install XAMPP to C:\Program Files (x86) (missing write permisssions). Or deactivate UAC with msconfig after this setup.
安装目录最好选择C盘之外的其它磁盘，如果选择C盘安装，由于用户权限原因，会出现创建一些文件失败的问题。如果你已经据有最高权限，可以直接装在C盘。
win10 下安装遇到下面问题
Problem running post-install step. Installation may not complete correctly. Installation failed(php.exe). Perhaps you have to install the Microsoft Visual C++ 2008 Redistributable package. After that please execute the setup_xampp.bat in the xampp fplder manually.
3、启动

Solutions 2: Change Default Port 80,443 of XAMPP Apache Server
So, the best solution like EL.Web.ID and Geethika says, is to reconfigure the XAMPP Apache server to listen and use different port numbers. Here is how you do it:
1) First, you need to open the Apache “httpd.conf” file and configure it to use/listen on a new port no.
setup xampp apache
To open httpd.conf file, click the “Config” button next to Apache “Start” and “Admin” buttons. In the popup menu that opens, click and open httpd.conf
2) Within the httpd.conf file search for “listen”. You’ll find two rows with something like;
#Listen 12.34.56.78:80
Listen 80
Change the port no to a port no. of your choice (e.g. port 1234) like below
#Listen 12.34.56.78:1234
Listen 1234
3) Next, in the same httpd.conf file look for “ServerName localhost:” Set it to the new port no.
ServerName localhost:1234
4) Save and close the httpd.conf file.
5) Now click the Apache config button again and open the “httpd-ssl.conf” file.
6) In the httpd-ssl.conf file, look for “Listen” again. You may find:
Listen 443
Change it to listen on a new port no of your choice. Say like:
Listen 1443
7) In the same httpd-ssl.conf file find another line that says, “<VirtualHost _default_:443>”. Change this to your new port no. (like 1443)
7) Also in the same httpd-ssl.conf you can find another line defining the port no. For that look for “ServerName”. you might find something like:
ServerName www.example.com:443 or ServerName localhost:433
Change this ServerName to your new port no.
8) Save and close the httpd-ssl.conf file.
9) Finally, there’s just one more place you should change the port no. For that, click and open the “Config” button of your XAMPP Control Panel. Then click the, “Service and Port Settings” button. Within it, click the “Apache” tab and enter and save the new port nos in the “main port” and “SSL port” boxes. Click save and close the config boxes.
That should do the trick. Now “Start” Apache and if everything goes well, your Apache server should start up.
You will also see the Apache Port/s no in the XAMPP control panel has change to the new port IDs you set :)
