启动Tomcat服务器弹出框报错：

Several ports (8005, 8009) required by Tomcat v7.0 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).

尝试改端口号：80,80

改完端口号之后，重启Tomcat又报错：

Server Tomcat v7.0 Server at localhost failed to start.

还是把端口号，改回原来的8005,8009。

启动任务管理器，杀掉tomcat进程，原因是：之前装了一个tomcat，冲突了。
