I installed Jenkins previously but it had some issue (there was no start icon) in the folder, so I uninstalled it. Now I'm trying to install it again, but it tends to pop this error:
I tried all the solutions mentioned in this post , but no success - Jenkins failed to start - Verify that you have sufficient privileges to start system services
As mentioned in the option 2 of the post, I tried to start jenkins in services but got a 1067 error
I read a lot of similar posts, but none of them really helped. I believe my user has enough privileges to work without causing any trouble, so the underlying problem is something else. Please help me figure out the issue.
I found the solution!
Turns out Jenkins doesn't work on other JDKs except for 8,11. And I have the 14th version. I'm putting the link to the answer that helped me change the JDK version.
Jenkins requires Java versions [8, 11] but you are running with Java 16 from C:\Program Files\Java\jdk-16.0.1
I'm running the Jenkins as a Docker container on a Virtual Machine on Google Cloud Platform. On the very first screen of setup, I can see that a lot of plugins did not install in my Jenkins server?
Please let me know how to resolve this issue? Is it something due to with the security on the cloud by default which restricts downloading of plugins?

Something similar happened to me when running Jenkins on Docker on my local machine. To get everything to install I had to keep retrying. It took several retries but eventually I got everything installed.
I'm not sure why this is the case. Maybe it fails downloads whose dependencies aren't installed yet?
I have installed Jenkins on Linux CentOS, after setting up the proxy it asks to install plugins, i selected few plugins and after proceeding to install them some of them failed and the install bar completes for other plugins but the page hangs forever and i am not able to proceed further.
Attached image for reference.
Please suggest !
Same issue here, tried:
refreshing page
force refresh
restarting Jenkins
restarting machine
Eventually just opened up the folder and removed the .hpi entries for those items. I didn't want to install them in the first place.
I updated some plugins and restarted the jenkins but now it says:
Please wait while Jenkins is restarting
Your browser will reload automatically when Jenkins is ready.
It is taking too much time (waiting from last 40 minutes). I have only 1 project with around 20 builds. I have restarted jenkins many times and worked fine but now it stucks.
Is there any way out to kill/suspend jenkins to avoid this wait?
I had a very similar issue when using jenkins build-in restart function. To fix it I killed the service (with crossed fingers), but somehow it kept serving the "Please wait" page. I guess it is served by a separate thread, but since i could not see any running java or jenkins processes i restarted the server to stop it.
After reboot jenkins worked but it was not updated. To make it work it I ran the update again and restarted the jenkins service manually - it took less than a minute and worked just fine...
Jenkins seems to have a number of bugs related to restarting, and at least one unresolved: jenkins issue
Windows ONLY....
All the solutions here didn't work and restarting the server was not an option. If you are in the same situation.
I had to kill java.exe and restart the jenkins service. After I did this Jenkins reloaded several times and then went back to normal.
I was stuck on the jenkins restarting page for 10-ish minutes untill I did this.
Hope this helps.
Running this in the command line helped me:
service jenkins restart
I had a similar issue when updating plugins from the pluging update page and I marked the restart jenkins options. jenkins only showed the waiting message for a long time.
I solved the issue restoring .bak to .jpi files of the the plugins that I tried to update.
I did the follow in my jenkins
cd $JENKINS_HOME/plugins/
>sudo mv git.bak git.jpi
.
. (more plugins files)
.
>sudo mv ldap.bak ldap.jpi
>sudo /sbin/service jenkins restart
Check Event Viewer.
I found that my Java died.
Faulting application java.exe, version 7.0.250.17, time stamp 0x51c4b3fd, faulting module ntdll.dll, version 6.0.6002.18541, time stamp 0x4ec3e39f, exception code 0xc0000374, fault offset 0x000abc4f, process id 0x1188, application start time 0x01cee4f42968bc81.
Finally I found that it's Jenkins 1.540 problem. Don't use it.

I faced the same issue after upgrading some plugins on Windows. Looking on jenkins.err.log it displayed this error
Exception in thread "main" java.io.IOException: Jenkins has failed to create a temporary file in C:\Users\builder\AppData\Local\Temp\

The problem was that the TEMP folder of the jenkins user had lots of temporary files. After cleaning that folder jenkins restarted correctly.
just performed a restart on the server. That fixed the issue !
In Command prompt execute this
C:\>service jenkins restart
Or
You can go for Service currently running in your machine( Win + R ) seach for Jenkins and Click on restart
For me, the cause seemed to be having lots of old job build logs hanging around. To clean them up, I ran:
cd $JENKINS_HOME/jobs
find -name 'builds' | xargs -n 1 bash -c 'rm -rf $0/[1-9]*'
Then I stopped and started Jenkins again, and it came up within a minute.

This is an old thread.. but my personal recommendation is to WAIT before attempting to do anything (such as restarting service, etc).
I wasted hours once trying to fix something that turned out to be not an issue in the first place. In the end, I messed things up and wasted a lot of time.
Just because you see errors in the logs doesn't necessarily mean that you need to take action.
The upgrade took about 45 minutes in the end for me. All i did at one point was refreshing my browser window. It can take a while.
Just my opinion
On Win 10: Stopping with the service command from the command line reported failure to stop the service, but I was able to stop it from services.msc (running as administrator). The updates were applied. Sorry, no definitive answer from me. YMMV.
I used TCPView and killed process that was using port 8080. BAsically it was all Java.exe from Jenkins. Killed all processes and restarted Jenkins Service
try to restart that inside windows services console, it will work
I have observed the same issue after installing a plugin and opting to restart the jenkins when no jobs are running.
When I looked at the jenkins server process, it was running fine and no issues.
On restarting the jenkins service using the below command and reloading the browser, Jenkins was up.
sudo service jenkins restart
If Jenkins is taking an unusually long time to restart the best recourse is to check the generated logs to see what may be wrong. However, even that may be of little help because many plugins try to be "quiet" by default, even if they are furiously working to load content. So if all else fails, you may have to resort to manually disabling plugins.
However here is a free tip: Some plugins are known to be messy. For example the Job Config History plugin we observed to write hundreds of thousands of records for both job configuration changes AND agent changes. Removing this plugin, and deleting the configHistory folder fixed one problem where our startup literally took > 4 hours.
In our case, the problem was we were launching ephemeral agents (via docker and/or kubernetes). Each new "agent" was treated as a configuration change. With thousands of agents per day, it didn't take long to fill up a substantial part of the disk with history that never was effectively cleared.
There are other plugins that leak data in this way. And you can also create self-inflicted wounds, e.g. by using a standalone process to remove "obsolete" files. An example where we were "bitten" is a process that tried to discard old build records, but did an incomplete job - and was "warring" with the running Jenkins process. Jenkins will try breaking its neck to load a build.xml record that is empty or incomplete.
Three more tips:
You can install the monitoring plugin. Often when the jenkins UI proper didn't start, we were able to see the /monitoring in action.
Likewise, /userContent can often be loaded even when the rest of the UI is not fully up.
Don't rule out bad actors. It just takes one aggressive script that tries, e.g. to load the entire build history and ship it back via a REST call to effectively deny service to all other UI users.
I try to fix a file named hudson.model.UpdateCenter.xml located /var/lib/jenkins
I change the URL to https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json
Finally, restart Jenkins. it solves my problem
I setup a Jenkins server on a redhat linux VM a while back to run our unit and integration tests. It has worked without much trouble for about two months, but now I suddenly can no longer browse to the GUI/HUB. I don't believe I have changed anything (I know everyone says that :) ) however when I look at the logs I get the following errors
WARNING: Untrapped servlet exception
winstone.ClientSocketException: Failed to write to client
at winstone.ClientOutputStream.write(ClientOutputStream.java:41)
The Jenkins service is running, I have restarted it and the VM with no resolution to this issue. Even the jenkins jobs that I have written are still running as far as I can tell providing emails every now and again, but I cannot browse to the GUI. Anyone run into something like this before. I've searched for this issue and some people have been suggesting to re-install jenkins, but I am not trying to do that!
alright a long time later I finally figured it out. Turns out winstone was not the issue, but rather file permissions were to blame. Some of the files in my jenkins folder /var/lib/jenkins/ had root as their owner rather than jenkins. There were some in .m2 some in .grails and just scattered all about, not sure how this happened.
Anyway I just navigated to the home dir of jenkins /var/lib/jenkins and ran the following command
chown -R jenkins:jenkins jenkins
