    I used RHEL7 and followed above commands. However the server is not listening on 8080. I tried to do a telnet from localhost but it says connection refused.
    Please if any help.
    Also no log file getting generated under /etc/var/log/jenkins

    When I do : netstat -anp |grep 8080 , No output is coming.
    However when I do : sudo service jenkins status, below output is coming –
