Not able to access Nexus console on my Ubuntu VM instance in GCP

I have installed Nexus (as a service) on my Ubuntu VM instance and while creating the vm instance, I have also checked "Allow HTTP traffic" and "Allow HTTPS traffic" options.

When I do a $ tail -f /opt/sonatype-work/nexus3/log/nexus.log, I see that Nexus is running:

2021-07-30 06:20:10,046+0000 INFO  [jetty-main-1]  *SYSTEM org.eclipse.jetty.server.handler.ContextHandler - Started o.e.j.w.WebAppContext@73ded096{Sonatype Nexus,/,file:///opt/nexus/public/,AVAILABLE}

Started Sonatype Nexus OSS 3.32.0-03

When I do a : $ sudo netstat -pnltu | grep -i "8081", I see:

tcp        0      0 0.0.0.0:8081            0.0.0.0:*               LISTEN      11722/java

Also, a $ sudo systemctl status nexus :

● nexus.service - nexus service

Jul 30 06:19:21 ubuntu-nexus nexus[11541]: Starting nexus

But, When I try to access the Nexus console through the vm instance's external ip with nexus' port-> http://34.xxx.xx.xxx:8081/ I am not able to access it (This site can’t be reached).

Is there any firewall settings in GCP, that needs to be done?

Solution

  • "Allow HTTP traffic" and "Allow HTTPS traffic" only open port 80 and 443, while Nexus is listening on port 8081. Either change the listening port or open port 8081
