Tomcat啟動報錯：Several ports (8005, 8080, 8009) required by Tomcat v7.0 Server at localhost are already in use

1、問題描述

　　通過Eclipse啟動tomcat報錯：Several ports (8005, 8080, 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)，按照網上的解決辦法改端口也沒有用（通過netstat -ano根本就沒有發現端口被占用）。

2、解決辦法

查看logs里的日志發現啟動報錯了：

java.net.SocketException: Unrecognized Windows Sockets error: 10106: create
	at java.net.ServerSocket.createImpl(ServerSocket.java:308)
	at java.net.ServerSocket.getImpl(ServerSocket.java:257)
	at java.net.ServerSocket.bind(ServerSocket.java:376)
	at java.net.ServerSocket.<init>(ServerSocket.java:237)
	at org.apache.catalina.core.StandardServer.await(StandardServer.java:440)
	at org.apache.catalina.startup.Catalina.await(Catalina.java:769)

	at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:353)
	at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:493)

　　

3、操作步驟

　　打開cmd，輸入：netsh winsock reset  然后回車

　winsock是Windows網絡編程接口，winsock工作在應用層，它提供與底層傳輸協議無關的高層數據傳輸編程接口 netsh winsock reset 是把它恢復到默認狀態
