Apache在Xampp中启动时显示错误

Question

我最近安装了xampp服务器，版本为7.3.1。当我尝试启动mysql和apache时。 sql服务器正常启动，但Apache无法启动，并显示以下错误

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

11:05:48 AM  [Apache]   This may be due to a blocked port, missing dependencies,

然后，我在Google上进行了搜索，发现我们需要将端口号80更改为任何数字。因此，我从80更改为81，然后重新启动服务器，它显示了相同的错误。

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

有什么解决办法

Answer 1

尝试运行apache_start.bat来查看端口是否确实是问题所在。
