Specifying Jenkins startup parameters

[David Aldrich]

Hi

 

We typically restart Jenkins using 'Restart Safely' from the root menu. We now want to specify the session timeout using a startup parameter:

 

java -jar jenkins.war --sessionTimeout=10080

 

How do people typically specify startup parameters?  Should I use a script and never restart from the root menu?

 

Best regards

 

David

It depends on the context where you're running that server.  Refer to https://jenkins.io/download/ for the current list of platform specific installers and the instructions to use them.

If you're running on a Debian or Ubuntu server, you should be able to modify the command line arguments in /etc/defaults/jenkins.  See https://wiki.jenkins.io/display/JENKINS/Installing+Jenkins+on+Ubuntu for more details.

If you're running on a CentOS, Red Hat or OpenSUSE, you should be able to modify the command line arguments in /etc/sysconfig/jenkins.  See https://wiki.jenkins.io/display/JENKINS/Installing+Jenkins+on+Red+Hat+distributions 

If you're running on Windows, there is a configuration file written to the installation directory which can be changed.  See https://wiki.jenkins.io/display/JENKINS/Thanks+for+using+Windows+Installer

Hi Mark

 

Thanks for your reply.  I’m working on Centos 5, so I set the last line of /etc/sysconfig/jenkins to:

 

JENKINS_ARGS="--prefix=/jenkins --sessionTimeout=540"

 

I then restarted Jenkins using root menu > Restart Safely.  After ~30mins inactivity I had to log in to Jenkins again.

 

Do you have any ideas why this is not working for me please?

 

Best regards

 

David

I believe the safe restart does not execute the operating system level startup scripts.  You need the operating system level restart,  like /etc/init.d/jenkins restart.
