【问题描述】：
我最近安装了xampp 7.3.1 版本的服务器。当我尝试启动mysql 和apache 时。 sql server 正常启动，但 Apache 没有启动，显示如下错误
11:05:42 AM [Apache] Problem detected!
11:05:42 AM [Apache] Port 80 in use by "Unable to open process" with PID 4!
11:05:42 AM [Apache] Apache WILL NOT start without the configured ports free!
11:05:42 AM [Apache] You need to uninstall/disable/reconfigure the blocking application
11:05:42 AM [Apache] or reconfigure Apache and the Control Panel to listen on a different port
11:05:42 AM [Apache] Attempting to start Apache app...
11:05:42 AM [Apache] Status change detected: running
11:05:48 AM [Apache] Status change detected: stopped
11:05:48 AM [Apache] Error: Apache shutdown unexpectedly.
11:05:48 AM [Apache] This may be due to a blocked port, missing dependencies,
11:05:48 AM [Apache] improper privileges, a crash, or a shutdown by another method.
11:05:48 AM [Apache] Press the Logs button to view error logs and check
11:05:48 AM [Apache] the Windows Event Viewer for more clues

后来我google了一下，发现我们需要将端口号80改成任意数字。所以我将 80 更改为 81 并再次重新启动服务器，它显示相同的错误。
我做了如下端口更改
#Listen 12.34.56.78:81 #changed 80 to 81
Listen 81 #changed 80 to 81
ServerName localhost:81 #changed 80 to 81
【问题讨论】：
-
您应该尝试改用 Devserver (easyphp.org)。使用 Devserver，如果一个端口已被使用，它会自动使用另一个端口。
-
这个 Devserver 是否具有与 Xampp 相同的功能？ @PeterEstiven
-
是的，而且我认为更多。有几个模块可用。
