今天Tomcat突然停止连接http://localhost:8080。它一直工作到昨天，我没有改变任何东西。Windows - Windows 7 64 位。Tomcat - 7.0.59。任何人都可以请帮忙。

Following is my server.xml

以下是我的 server.xml

<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443" />

-->
<!-- Define a SSL HTTP/1.1 Connector on port 8443
     This connector uses the BIO implementation that requires the JSSE
     style configuration. When using the APR/native implementation, the
     OpenSSL style configuration is required as described in the APR/native
     documentation -->

Looks like other app is using that port (it may be another running instance of tomcat or another app in general). Use netstat -anob(as shown to check here) to find the culprit and close it.

看起来其他应用程序正在使用该端口（它可能是另一个正在运行的 tomcat 实例或其他应用程序）。使用netstat -anob（如图所示在此处检查）找到罪魁祸首并关闭它。

The problem is this (read what it says - attentively) :

问题是这样的（阅读它所说的 - 用心）：

Jul 2, 2015 12:30:51 PM org.apache.catalina.startup.Catalina stopServer SEVERE: Could not contact localhost:8005. Tomcat may not be running.

2015 年 7 月 2 日下午 12:30:51 org.apache.catalina.startup.Catalina stopServer 严重：无法联系 localhost:8005。Tomcat 可能没有运行。

Tomcat listens for shutdown commands on another port than it does for http requests. The shutdown port is defined as an attribute in the element (I believe) of your server.xml. The default installation listens on port 8005. But if that attribute is removed, the server won't open that port and shutdown must proceed differently (or not at all).

Tomcat 在另一个端口上侦听关闭命令，而不是侦听 http 请求。关闭端口被定义为 server.xml 的元素（我相信）中的一个属性。默认安装侦听端口 8005。但是如果删除该属性，服务器将不会打开该端口并且关闭必须以不同的方式进行（或根本不进行）。
