003-PHP基础-01-PHP快速入门 03-PHP环境搭建
1、客户端（浏览器）
IE FireFox CHROME Opera Safari
2、服务器
是运行网站的基本
是放置程序代码的地方
环境：apache/nginx
开发环境：XAMP/WAMP
X：Linux/IOS/Windows
A：apache
M：MySQL
P：PHP
服务器环境：LAMP
Linux
apache
MySQL
PHP
注：以上是主流开发环境与服务器环境，不是绝对是这样的一个组合
搭建服务器的方式
1.集成安装环境
2.单独配置（相对新手比较复杂）
3、使用XAMPP搭建服务器
1.XAMPP是什么
XAMPP（Apache+MySQL+PHP+PERL）是一个功能强大的建XAMPP软件站集成软件包
图-1
2.XAMPP下载地址
https://www.apachefriends.org/zh_cn/index.html
根据自己的系统下载相应的安装包
我的操作系统是Windows 10，我就下载最新版本的（XAMPP for Windows v5.6.3(PHP5.6.3)（此版本可能已经不是最新版的））（如图-2）
图-2
注：此内容页显示的是最新版本的，最新版本的XAMPP for Windows 不再支持 Windows XP和Windows Server 2003。
Windows XP和Windows Server 2003 可以点击“下载 点击这里获得其他版本”标签，去下载早期版本。
然后会跳转到这个页面（如图-3）
正常情况下会自动呼出下载文件窗（如图-4），如果没有呼出，则点击“点击这里”
图-3
选择保存位置，点击“下载”（如图-4）
图-4
3.安装XAMPP集成包
下载好的文件（如图-5），右键“使用管理员身份运行”（针对Windows 7版本以上 的用户）
图-5
点击“NEXT”继续（如图-6）
图-6
默认是安装所有组件（如图-7）
图-7
我只安装必要组件和我所需要的组件，其他FTP服务器，Mail服务器等我暂时没用到不选择安装，选好了继续点解“Next”下一步（如图-8）
图-8
选择安装路径
注：默认是安装在C盘的，不推荐安装在系统盘，我自己选择安装在D盘
选好安装路径后，点击“Next”继续下一步（如图-9）
图-9
这里有个复选框说“了解更多关于Bitnami XAMPP”，复选框勾去掉！（如图-10）
图-10
点击“Next”，下一步（如图-11）
图-11
点击“Next”下一步，准备安装（如图-12）
图-12
安装中。。。莫慢待。。。（如图-13）
图-13
安装完成
询问：”Do you want to start the Contrl Panel now”是否马上要打开控制面板，默认选中。点击Finish（完成）。（如图-14）
图-14
=============================华丽的分割线=====================
4.apache无法正常启动的解决方案（非所有问题的解决方案）
通常情况下到这一步安装已经完成，能够正常启动XAMPP Control Panel，当然也有特殊情况：（如图-15）
图-15
大概意思是说默认端口80被其他程序给占用了。所有apache无法正常工作。
由于我在之前已经安装了IIS，默认端口也是80
在这里有两个选择
1、干掉占用80端口的程序（比如我电脑里面的IIS，有点残暴。。。）
2、修改apache默认端口
由于IIS我还要用来发布ASP.NET程序，这里我选择修改apache默认端口
如何修改apache默认端口（两种方式）
1.第一种方式：点击XAMPP Control Panel 中Apache这一行对应的“Config” 按钮展出菜单， 点击Apache（httpd.conf）;（如图-16）
图-16
然后会自动打开httpd.conf文件。（如图-17）
图-17
第二种方式：找到httpd.conf文件（这个文件在哪）
httpd.conf的目录：path\xampp\apache\conf
path是xampp安装的目录，我选择安装在D盘，所以我的httpd.conf的目录是：D:\xampp\apache\conf（如图-18）
图-18
我喜欢第二种方式，因为通常修改文件前最好做个备份。
修改哪些地方（需要修改两个地方）
1.“Listen 80” 改成“Listen 81”（可以不是81，8080也可以，不被其他程序占用的端口都能使用）
修改前（如图-19）
图-19
修改后（如图-20）
图-20
2.“ServerName localhost:80”改成“ServerName localhost:81”
修改前（如图-21）
图-21
修改后（如图-22）
图-22
保存。
启动apache
点击Apache行对应的“Start”实际上Apache字样背景色变浅绿色的时候是可以正常使用了的。
但是为什么还会报红呢，这跟XAMPP里面的设置ini文件 有关，XAMPP默认初始化文件ini里面初始化apache默认端口号依旧是80.
然后当初始化到具体apache文件的时候，发现端口号已经是修改之后的81.
所以是正常的。
但是，保红虽然能运行，但是看得总是让人不自然，总之就是不爽。（如图-23）
图-23
如何解决
如果已经启动，先点击Apache行对应的“Stop”，暂时停止运行。
然后看手顺图（如图-24，如图-25）
图-24
图-25
把（如图-25）标注“3”的地方改成81，然后点击标注“3”的“Save”保存，点击标注“2”的“Save”保存。
点击Stop变成Start正常启动。。。（如图-26）
图-26
Apache已经正常启动（如图-27）
图-27
最后就可以点击XAMPP Control Panel “Quit”退出按钮关闭XAMPP控制面板。（如 图-28）
图-28
==============================华丽的分割线===========================
5.测试安装的环境
浏览器：（URL）地址栏键入：localhost:81（如果端口默认是80则键入localhost）,回车。出现如下页面这表示XAMMP安装（配置）已经成功啦。（如图-29）
