当我在eclipse上启动tomcat时，我得到了这个消息：
本地主机上的Tomcat v6.0 Server所需的端口8009已被使用。 服务器可能已经在另一个进程中运行，或者系统进程可能正在使用该端口。 要启动此服务器，您需要停止另一个进程或更改端口号。
当我手动启动tomcat时，它给了我这个exception跟踪：

用netstat -ntlp | grep :8009查看 netstat -ntlp | grep :8009看看哪个进程正在使用8009。
先杀死进程。 然后检查你的％TOMCAT_HOME％/ conf / server.xml文件。 你应该用port =“8010”替换port =“8009 ” 。
通过运行ps -ef | grep tomcat双重检查 如果有任何java进程正在运行来终止它， ps -ef | grep tomcat kill -9进程或从你的任务管理器。 很可能你以前的tomcat启动会话没有正常结束。
您的端口8009已被使用。 它可以是另一个tomcat或不同的东西。
你应该手动杀死任何tomcat进程。
编辑：假设你在Windows平台上，使用CTRL-ALT-Suppr杀死所有javaw.exe进程
检查文件server.xml中的文件\apache-tomcat-6.0.32\conf将提及port address ，如果是8080 ，请尝试将其更改为8081并启动服务器并调用localhost:8081
在server.xml ，它将如下所示：
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />
