Unrecognized Windows Sockets error:0: Jvm_bind

1. Questions

When you start Tomcat through eclipse, you throw an exception java.net.SocketException:Unrecognized Windows Sockets error:0: Jvm_bind. The reason for this exception is that the server port is occupied

The solutions include the following two kinds of methods:

One: Change the port number of the server;
Second: Close the process that occupies the port currently occupied

2. Change the server port number

To the Server.xml file under the Conf folder under the Tomcat directory, locate
<connector port= "8080" protocol= "http/1.1" connectiontimeout= "20000" redirectport= "8443"/>
Modify the port to
<connector port= "8088" protocol= "ajp/1.3" redirectport= "8443"/>

3. Close the process that currently occupies the port

1) First enter the command line to see if the port is occupied
Use command: Netstat-ano

The port of my server is 443
This port has been occupied by a process with a PID of 3432

2) End the PID 3432 process through the Task Manager or the Taskkill program.
