java.net.bindexception address already on running more than one tomcat

Question

I am trying to run more than one tomcat instance on my server. I can successfully run tomcat 7 on port 8080. I am trying to run another tomcat on port 8181 the server is refusing to start with the following error

java.net.bindexception address already in use

This is my port configuration

<Connector port="8181" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

Please what could be wrong. Kindly assist.

Answer 1

Tomcat uses three ports while it's running.

By default it's 8080 for HTTP, 8005 for SHUTDOWN and 8009 for AJP.

You've changed 8080 to 8181, so change below two configurations as well.

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

<Server port="8005" shutdown="SHUTDOWN">
