问题:

I have a clean ubuntu installation (14) and try to run Tomcat7. I have installed it via terminal, run the "sudo service tomcat7 start" command which should start tomcat, but when I try to open: localhost:8080, the welcome index page is not loading and I get a 404 error (file not found). The 8080 port is not opened either, it seem like some kind of permission problem.

Netstat gives the following (note there is not listening for 8080 with tomcat started)

android@localhost:~$ netstat -a | more

Solved:

The 8080 port was not in use, I even tried to change it to 8089 to be sure. There was something other, anyway. I have removed all tomcat7 via command line, and reinstalled manually. After installing the latest version from the Apache website everything was ok.

Step by step guide can be found here.

回答1:

Perhaps you have another service running on port 8080, or your kernel somehow has that port closed. Try configuring another port and see if the problem persists.

Edit: Ok, here comes the actionable part: open a terminal and run 

netstat -t | grep 8080

This should show you anything currently listening on port 8080. As Ubuntu doesn't activate a firewall out of the box, this is very likely the source of the problem.

Another edit: The original question did not state that you were on Android. This is a vital piece of information, as Android includes SELinux, which forbids opening a port without prior consent from the security layer. To allow opening the port, look here.



回答2:

Here you just have to change the port number from the tomcat manager because some applications may already using the port you given as 8080.

Use the following method...

How to change the port of Tomcat from 8080 to 80?
