How do I know if Tomcat is running terminal?
A simple way to see if Tomcat is running is to check if there is a service listening on TCP port 8080 with the netstat command. This will, of course, only work if you are running Tomcat on the port you specify (its default port of 8080, for example) and not running any other service on that port.
How do I stop Tomcat from running in the background?
To stop the Windows service, do these steps:
- Click the Start menu and right-click Computer and select Manage.
- Expand Configuration and click Services.
- Right-click the Tomcat service and select Stop.
Why is netstat-a | grep 8080 not showing up?
Now when I do netstat -a | grep 8080, it doesn’t show up in output. After stopping jenkins my process successfully bound to 8080. Any clues what happening? I’m running CentOS. Just had a similar case on Ubuntu 14.04. Indeed jenkins default port (8080) is mapped to “http-alt” name in /etc/services.
How to find the Tomcat entry in netstat?
Process ID of the listening Process will be shown when running netstat with -p. So use netstat -pa | grep http-alt or netstat -pan | grep :8080 to see the tomcat Entry. Alternately, use lsof -P | grep :8080 which will also show the Process ID & Process Name owning the socket which is listening on Port 8080.
Why is netstat-ATNP not listening on port 8080?
Unfortunately it is not responding on port 8080 however and netstat -atnp | grep LISTEN does not list it. Any ideas of what could cause this? It was iptables blocking the port… In general iptables should be enabled but configured to open the ports needed.
Why does grep not show up for port 8080?
Because Port Number 8080 is getting converted to string http_alt, which will not match the grep pattern. From https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers , we can see that Port 8080 is Officially “HTTP alternate (http_alt)—commonly used for Web proxy and caching server, or for running a Web server as a non-root user”.
