Failed to contact localhost: 8005. Tomcat may have error disconnecting tomcat

Hi I am trying to shutdown and start tomcat server. But when running shutdown.sh I get below error. Please check below error and invite me to fill.

Mistake:

Using CATALINA_BASE:   /opt/tomcat8
Using CATALINA_HOME:   /opt/tomcat8
Using CATALINA_TMPDIR: /opt/tomcat8/temp
Using JRE_HOME:        /usr/java/jdk1.8.0_74

There is some application running on port 8005 due to which tomcat cannot bind the network to the port. Your shutdown.sh will throw an exception because the server has not started yet (as there was a problem starting the server)



  • Solution 1 (recommended): change port from 8005 to 8006 in / opt / tomcat 8 / conf / server.xml
  • Solution 2: Please check which app is using 8005 on netstat -tulnp | grep 8005

    and disable it.

if the timestamps are correct it says that your tomcat startup failed around 11:00 pm and you tried to shutdown a non-existing tomcat service at 11:00

try to start with. /catalina.sh run is ok then it will show up on screen or it will show some error like in my case

[root@localhost bin]# ./catalina.sh run

Invalid maximum heap size: -Xmx512MB
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

resize the memory heap then it will definitely work
