Jenkins fails when running “service start jenkins”

Question

I installed jenkins on Cnetos 7 using the following:

sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins.io/redhat-stable/jenkins.repo
sudo rpm --impor         


        

Answer 1

For ubuntu 16.04, there is firewall issue. You need to open 8080 port using following command:

sudo ufw allow 8080
