IntelliJ，无法启动简单的 Web 应用程序:无法在 localhost:1099 上 ping 服务器 [英] IntelliJ, can't start simple web application: Unable to ping server at localhost:1099

问题描述

我正在尝试按照本教程在 IntelliJ 中制作一个简单的 Web 应用程序:http://wiki.jetbrains.net/intellij/Creating_a_simple_Web_application_for_Tomcat_in_IntelliJ_IDEA_12

I'm trying to make a simple web app in IntelliJ by following this tutorial: http://wiki.jetbrains.net/intellij/Creating_a_simple_Web_application_for_Tomcat_in_IntelliJ_IDEA_12

我相信我的 Tomcat 安装正确，因为我在去的时候看到了 tomcat 图片http://localhost:8080/

I believe my Tomcat is installed correctly since I see the tomcat pictures when I go to http://localhost:8080/

我已按照所有步骤进行操作，直到它告诉我运行 index.jsp 的部分，此时我收到错误消息:

I've followed all the steps up until the part it tells me to run index.jsp, at which point I get the error:

Error: Exception thrown by the agent : java.net.MalformedURLException: Local host name unknown: java.net.UnknownHostException: nodename nor servname provided, or not known

我在日志中看到了这一点:

I see this in the log:

Application Server was not connected before run configuration stop, reason:
           Unable to ping server at localhost:1099

这个 1099 来自 Run -> Edit Configurations 中的 JMX 端口.

This 1099 comes from the JMX port in Run -> Edit Configurations.

我该如何解决这个问题?

How do I fix this?

推荐答案

要解决此问题，您需要在/etc/hosts 文件中添加您的机器名称以指向 localhost(127.0.0.1).

To fix this you need add your machine name in the /etc/hosts file to point to localhost(127.0.0.1).

您可以通过运行以下命令找到您的机器名称:

You can find your machine name by running the following command:

$ hostname
macbook-pro

从上面的输出你知道你的主机名是macbook-pro".编辑/etc/hosts"文件并在列出 127.0.0.1 的行的末尾添加该名称

From the output above you know your hostname is "macbook-pro". Edit "/etc/hosts" file and add that name at the end of line that lists 127.0.0.1

127.0.0.1 localhost macbook-pro

保存文件.

现在您的 IntelliJ 应该可以启动您的服务器了.

Now you IntelliJ should be able to start your server.
