启动 Tomcat 服务器报错：

Several ports (8005, 8080, 8009) required by Tomcat v5.5 Server at localhost are already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the port number(s).

原因：端口8005, 8080, 8009被占用了。可能是在打开Tomcat的情况下关闭了Eclipse，或是Eclipse非正常关闭，导致先前的Tomcat没有被关闭，端口占用。或是其他软件占用了tomcat的端口号。

**解决方法：**  
**方法1：杀掉占用端口的软件。**

**打开任务管理器，找到[Java][]虚拟机相关的进程javaw.exe，将它结束掉。如果问题没有解决，往下看。**  
如果没有这个进程，那可能是其他软件占用了端口。  
在开始菜单->运行->cmd->输入 netstat -ano 或netstat -an | grep 8080 命令，可以查看哪个进程占用了8080和8009端口，找到占用端口软件的PID，然后在任务管理器找到对应PID的软件，关闭结束该进程即可。如果任务管理器中没有显示PID列，需要设置，查看---》选择列---》勾选“PID（进程标识符）”。

【或者】

在dos下，输入 netstat -ano|findstr 8080  
  
//说明：查看占用8080端口的进程  
  
显示占用端口的进程

taskkill /pid 6856 /f  
  
//说明，运行windows自带taskkill命令，将上面显示的进程号，结束掉。

方法2：修改tomcat默认端口号。

修改Tomcat的配置文件。  
例如：C:/tomcat5.5.25/conf/server.xml  
<Connector port="8080" maxHttpHeaderSize="8192"  
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"  
enableLookups="false" redirectPort="8443" acceptCount="100"  
connectionTimeout="20000" disableUploadTimeout="true" />

Connector 节点，将port="8080"中的端口改为一个没有被占用的端口。
