Question

我在服务器上安装了tomcat9，但我无法从webbrowser访问它。它说连接被拒绝了。

This site can’t be reached
localhost refused to connect.
Search Google for localhost 8081
ERR_CONNECTION_REFUSED

我尝试在server.xml文件中将默认端口8080更改为8081但它似乎不起作用。我尝试使用端口8080检查任何其他实例，但这也无法解决问题。这就是我在catalina日志中看到的

我还能在这里查看什么？

Answer 1

原因是

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

在您的localhost上，端口8080当前正在运行一个应用程序。可能是Web服务器的任何实例。您可以使用

在Linux / Unix上进行检查

netstat -lnp

在您将找到端口8080的行中，有一个占用此端口的进程号。终止此过程并启动服务器

无法从webbrowser访问tomcat
