Unable to access Jenkins from browser on Windows

Question

I installed Jenkins on CentOS 7 running in VMware Workstation. Jenkins Service is running:

 jenkins.service - Jenkins Service
   Loaded: loaded (/etc/systemd/system/jenkins.service; disabled; vendor preset: disabled)
   Active: active (running) since Tue 2016-06-21 08:47:46 PDT; 5s ago

IP of VM is 192.168.139.160. Host operating system is Windows 7.

When I try to access Jenkins from browser on Windows using http://192.168.139.160:8080/jenkins I get error: "This site can’t be reached". What am I doing wrong?

Answer 1

If you have installed Jenkins on CentOS 7.1, you should add a rule in firewall for port 8080, or at least disable firewalld.

To disable firewalld, you can use these commands:

systemctl stop firewalld

systemctl disable firewalld

After this you should be able to reach Jenkins on port 8080.

Answer 2

Stop Firewall + start tomcat

Find where you have the iptables, then put them down like this: /etc/init.d/iptables stop (might be some different location on your computer)

Then start up the tomcat you'll have a script like this: startup.sh (in my computer the path is /usr/share/apache-tomcat-7.0.56/bin/)

Answer 3

Please try it out.

First

JENKINS_HTTPS_LISTEN_ADDRESS="Public IP"  >> /etc/sysconfig/jenkins

Then

/etc/init.d/jenkins restart
