Problems with Tomcat not starting in eclipse

Several ports (8005, 8080, 8009) required by Tomcat v8.5 Server at localhost is already in use. The server may already is running in another process, or a system process could be using the port. To start this server you'll need to stop the other process or change the port number (s).

cause : This is due to the fact that Tomcat was previously turned on and the operation to turn on Tomcat is performed when you run Eclipse.

workaround : Double-click Shutdown.bat to close Tomcat and run in Eclipse in the installation directory of Tomcat (D:\ installation package \apache-tomcat-8.5.24\bin (my installation directory)).
