Tomcat 意外关闭

Question

我一直在研究 xampp tomcat 服务器，我是新手。我对其进行了配置并启动了 xampp tomcat。它工作正常，我看到我配置的所有端口都完美，但 3 分钟后它显示了这个错误

"Error: Tomcat shutdown unexpectedly.
4:55:38 PM  [Tomcat]    This may be due to a blocked port, missing dependencies, 
4:55:38 PM  [Tomcat]    improper privileges, a crash, or a shutdown by another method.

我打开 Catalina 日志以获取更多信息，我注意到这个 java 错误：

Answer 1

这就是原因：

原因：java.net.BindException：地址已在使用中：JVM_Bind :8080

这意味着服务器正在尝试绑定到端口8080，但您的机器已经绑定了一些东西。确保您的其他进程之一没有占用该端口，或选择另一个（可能在server.xml）来使用。

Answer 2

见：

Caused by: java.net.BindException: Address already in use: JVM_Bind

Tomcat 配置使用的端口已被另一个应用程序使用。

关闭其他应用程序，或编辑您的server.xml 文件以使用另一个端口（默认端口为 8080）。
