Jenkins startup issue

Hello All,

 

I have Jenkins server installed on a dedicated Jenkins machine(Windows 10). I was trying out something and in services, I have changed the "Logon As" from local System to my credentials. Since then i am unable to access Jenkins server, it shows the page attached in the screenshot below. 

When i click on skip to content it shows the below error

I also changed the "Logon As" in services to the one that was previously present i.e. "Local system". The issue still persists. After changing it to local system, when i manually start the service it automatically stops after few seconds.

 

Please help me retrieve the server back.

 

Thanks in advance,

Sharan Patil

    Hi Sharan, you can regain access to your Jenkins instance by following the instructions outlined here: https://support.cloudbees.com/hc/en-us/articles/206598218-How-do-I-login-to-Jenkins-when-I-locked-myself-out-

    Alternatively, if you have a backup of your $JENKINS_HOME folder prior to the change, you could restore from backup which would also resolve your issue: https://docs.cloudbees.com/docs/admin-resources/latest/backup-restore/

    Hello Ryan,

     

    Thank you for your swift response,

    The first link asks to change `<useSecurity>true</useSecurity>` to false and start Jenkins. I did that, its still the same. I unable to gain the access. Jenkins service stops after few seconds i start it from services. 

    Unfortunately I don't have of my $JENKINS_HOME folder's backup prior to the change.

    Thanks,

    Hi Sharan, 

    In looking closer at the screenshot you provided, it appears your filesystem permissions are preventing the service from starting. You'll need to ensure you have your permissions set in a manner that allow the Jenkins user to read/write to your defined C:/Program Files (x86)/Jenkins directory, otherwise the service will not start. If you are a CloudBees customer, I encourage you to submit a support request via the Support Portal.

    Hi Ryan,

    Can you please let me know how to do that? I don't want things to be messed up more. 

    Thanks,
