无法在Redhat上启动詹金斯

Question

I dowloaded and installed jenkins with the following commands on redhat (3.10.0-327.el7.x86_64 #1 SMP Thu Oct 29 17:29:29 EDT 2015 x86_64 x86_64 x86_64 GNU/Linux)

sudo wget  https://pkg.jenkins.io/redhat-stable/jenkins-2.32.2-1.1.noarch.rpm
rpm -ivh jenkins-2.32.2-1.1.noarch.rpm

And I started jenkins with the command

sudo service jenkins start

I got the output

Starting jenkins (via systemctl):                          [  OK  ]

But jenkins is not running. I tried ps ax | grep -i jenkins and no process named jenkins is running. I tried service --status-all and i can't see jenkins. I tried to access ip:8080 which is also not showing anything. But with systemctl status jenkins.service I can see that it started

Answer 1

For future reference and those who doesn't bother to read the comments. Besides checking the system logs you should check the Jenkins log, which on most *nix systems is located in /var/log/jenkins/jenkins.log . In this case it was insufficient permissions to /var/libs/jenkins .

BTW, If you can't find any errors in that log either, then you probably have some sort of ip-table issue where the Jenkins server can't be accessed from the outside.
