Unable to bind to port

jimderouin

During installation of Community as root user on Ubuntu 12.04, I get error Warning: Unable to bind to the given port number. Please select another Tomcat Server Port when setting up Tomcat AJP Port 8009. This port is not being used by another service. I tried lots of other ports and got the same error.

Complete the installation and then try chngeing ajp port to something else in conf folder of tomcat and restart server.

Installation will not continue without this being accepted. Don't know how to skip this step.

I found zip file and will try manual install

I'm not sure if the following command will work on ubuntu, but it works on CentOS.

netstat -tulpn

That should give you a list of ports and what PID's are using them.

The error message is missleading at this point.
I was running in the same "problem" on a server with an exiting plesk/tomcat installation where nothing was listening on 8009 as well.

In fact the error message must not only refer to AJP port (which is the last one you entered).
It refers to the block of tomcat ports (server port, shutdown port, ssl port and ajp port).
If one of these is used already you get the "Unable to bind to the given port number.".

So you should check the whole range here.
In my scenario I simply moved all tomcat ports into the range of 9080,9005,9443, 9009 and passed this installation step.

Thanks to You all, it worked fine for me! Alfresco 5.1 with Ubuntu LTS 14.04 😉

I had the same problem when trying to upgrade Alfresco to the latest version. In my case the java process was still running and owned the port numbers. Killing the process released the port numbers.

Use ESWBitto _'s suggestion and grep for the port numbers. See what I got below

</code><br><code>

root@la01:/opt# netstat -tulpn | grep 8080
tcp6 0 0 :::8080 :::* LISTEN 12099/java 

root@la01:/opt# netstat -tulpn | grep 8005
tcp6 0 0 127.0.0.1:8005 :::* LISTEN 12099/java 

root@la01:/opt# netstat -tulpn | grep 8443
tcp6 0 0 :::8443 :::* LISTEN 12099/java 

root@la01:/opt# netstat -tulpn | grep 8009
tcp6 0 0 :::8009 :::* LISTEN 12099/java 

For some reason process 12099 was still running. I killed it and the ports were released.

I hope this helps.
Cheers
