I need to install Jenkins in my localhost(CentOS) and I tried issuing the procedures in the following link:
https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+RedHat+distributions
But it gives an error saying,
Resolving pkg.jenkins-ci.org... 63.246.20.93 Connecting to pkg.jenkins-ci.org|63.246.20.93|:80... failed: Connection refused.
Though, wget http://pkg.jenkins-ci.org works fine.
Can anyone help me to resolve this issue?
I'd suggest you first download the war, and run java -jar jenkins.war to see if it works properly. It will start with the defaults.
If all is OK, maybe just wrap this with a script and configure it to run as a service.
I hope this helps.
EDIT: This is old, but worth mentioning that Jenkins has a formal Docker image you can use to quickly spin up a local instance for your tests. You can also mount a local directory into your container for persistence storage, which makes it a great option for your CI developments.
Quick test
docker run -p 8080:8080 jenkins
Better usage (with persistence storage)
docker run -d --name jenkins -p 8080:8080 -p 50000:50000 -v /local/dir:/var/jenkins_home jenkins
Point a browser to http://localhost:8080
