xammp=apache+php+mysql 相当于一个服务集成包吧，主要是帮助用户免去配置的烦恼。
问题描述：
但是xammp也会出问题，通常是启动不了apache服务，一般会显示如下错误信息：
9:20:15 [Apache] Status change detected: stopped <span style="color:#ff0000;">9:20:15 [Apache] Error: Apache shutdown unexpectedly. 9:20:15 [Apache] This may be due to a blocked port, missing dependencies, 9:20:15 [Apache] improper privileges, a crash, or a shutdown by another method. 9:20:15 [Apache] Press the Logs button to view error logs and check 9:20:15 [Apache] the Windows Event Viewer for more clues 9:20:15 [Apache] If you need more help, copy and post this 9:20:15 [Apache] entire log window on the forums</span>
<span style="color:#ff0000;">This may be due to a blocked port, missing dependencies, </span>表面意思是端口冲突，缺少依赖。

解决方案：（主要是针对端口问题）
1.常规做法
You shuld run file setup_xampp.bat in XAMP folder first!
2.修改apache监听端口
on your XAMPP control panel, next to apache, select the "Config" option and select the first file (httpd.conf): there, look for the "listen" line (you may use the find tool in the notepad) and there must be a line stating "Listen 80". Note: there are other lines with "listen" on them but they should be commented (start with a #), the one you need to change is the one saying exactly "listen 80". Now change it to "Listen 1337". Start apache now. If the error subsists, it's because there's another port that's already in use. So, select the config option again (next to apache in your xampp control panel) and select the second option this time (httpd-ssl.conf): there, look for the line "Listen 443" and change it to "Listen 7331". Start apache, it should be working now.
3.如果你装了skype，可能是skype占用端口，修改之
If you are using the latest Skype, go to: Tools -> Options -> Advanced -> connection. Disable the 'Use port 80 and 443 for alternatve.. ' Sign Out and Close all Skype windows. Try restart your Apache again.
It means port 80 is already used by another one. Simply follow these steps: Open windows -> click on Run (win + R) -> type services.msc Goto IIS Admin -> Right click on it and click on Stop Option. Open XAMPP click on Start Action of Apache Module, Apache Module is run. OR For find the port of Apache (80) in Command Prompt simply type netstat -aon it displays present used ports on windows, under Local Address column it shown as 0.0.0.0:80. If it displays this port another connection is already used this port number. Active Connections in Windows XP:
