Configured Jenkins, tried to change the port to: 5555 as 8080 is used by tomcat apache.

Edited: vim /etc/sysconfig/jenkins and updated JENKINS_LISTEN_ADDRESS="0.0.0.0" AND JENKINS_ARGS="0.0.0.0"

Restarted the jenkins Server: sudo service jenkins restart

Error:

This site can’t be reached ipaddress took too long to respond. Try:

Checking the connection Checking the proxy and the firewall ERR_CONNECTION_TIMED_OUT

ps aux | grep jenkins

Port 5555 looks fine with below query:

sudo lsof -i -P -n | grep LISTEN

java       6799     jenkins  165u  IPv6 9250567      0t0  TCP *:5555 (LISTEN)

Port 8080 is running for tomcat:

java       6269        root   50u  IPv6   48458      0t0  TCP *:8080 (LISTEN)

Anything missing in the configuration here?

what about 8080 port status? – asktyagi Jun 01 '19 at 04:41
updated my question for 8080 as well – Hansiemithun Jun 01 '19 at 04:43
check the port status from outside of server, check if those are reachable and responding within time. – asktyagi Jun 01 '19 at 04:45
How to ping and test specific port? – Hansiemithun Jun 01 '19 at 04:56

The first thing to look at is your firewall. – Michael Hampton Jun 01 '19 at 05:04
Yup, the firewall was not configured for the port @MichaelHampton. Added there, thanks – Hansiemithun Jun 01 '19 at 05:54
Strange is, i was able to setup jenkins with default plugins and created username and password. Also able to login, but there is blank screen, dont know why ? :( @MichaelHampton – Hansiemithun Jun 01 '19 at 06:05
I am so stupid, i should do a restart of jenkins after configuration, It worked :) – Hansiemithun Jun 01 '19 at 06:15
