1. Problem description

　　Start tomcat through Eclipse and report an error: 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), and it is useless to change the port according to the online solution (the port is not occupied at all through netstat -ano).

2. Solutions

Check the logs in the logs and find that the startup reported an error:

3. Operation steps

　　Open cmd, enter: netsh winsock reset and press Enter

　Winsock is a Windows network programming interface. Winsock works at the application layer. It provides a high-level data transmission programming interface that is independent of the underlying transmission protocol. Netsh winsock reset is to restore it to the default state
