I'm trying to run Tomcat 9 on my Raspberry Pi 3 B+ (running Raspbian) and I get this error when trying to start up:

30-Jan-2019 17:27:53.934 SEVERE [main] org.apache.catalina.util.LifecycleBase.handleSubClassException Failed to initialize component [Connector[HTTP/1.1-8080]]

Note: Raspbian is a Debian OS.

As the logs say:

also:

Failed to create server shutdown socket on address [localhost] and port [8005] (base port [8005] and offset [0])

which means some of the ports are occupied by another process (8080, 8005, 8009)

You can test it by:

telnet localhost 8080

You can know which process occupies which port by:

netstat -tulpn

  • Connection refused after using telnet.

  • Please also check for ports 8005 and 8009 (as seen from the logs)

  • Connection refused on both, and according to netstat nothing in the 8000s is being used,

  • Ports are network-card specific, I hope you have only one network interface.

  • I'm using a Raspberry Pi, so I assume I would only have one.
