How to restart Jenkins manually?

Answer 1

This can also be done using the Jenkins CLI:

java -jar jenkins-cli.jar -s http://[jenkins-server]/ restart

The jenkins-cli.jar file along with a full list of commands are available at http://[jenkins-server]/cli.

Answer 2

If it is deployed as a war file then restart the application server, for example, Tomcat.

Answer 3

If you have no permissions or access to the command line directly, you can do e.g. one of the following:

1. Create a job with shell/batch step that will trigger a restart from the Jenkins installation folder
2. Install/update some plugin while checking "restart after installation" (at least this works in old versions)

Both above are hacks, but I actively used them in a very restricted environment where no one wanted me to restart Jenkins, huh.

Answer 4

On Windows, if you installed it as a service, go to Services (Start → Run: services.msc), find Jenkins, right click → Restart.

If it does not help (UI is not responding) open the Windows Task Manager → Processes, kill the java.exe process, and restart the service once again.

Answer 5

The SafeRestart Plugin needs to be mentioned. It is pretty useful (Restart Safely). It adds a link to be able to restart from the main menu:

Answer 6

The below commands worked for me in Red Hat Linux and should work for Ubuntu also.

• To know the status of Jenkins:

  sudo service jenkins status
  

• To start the Jenkins:

  sudo service jenkins start
  

• To stop the Jenkins:

  sudo service jenkins stop
  

• To restart the Jenkins:

  sudo service jenkins restart
  

Demo on command prompt:

[root@varunHome]# sudo service jenkins status
jenkins (pid  7468) is running...

[root@varunHome]# sudo service jenkins stop
Shutting down Jenkins               [  OK  ]

[root@varunHome]# sudo service jenkins start
Starting Jenkins                    [  OK  ]

[root@varunHome]# sudo service jenkins restart
Shutting down Jenkins               [  OK  ]

Starting Jenkins                    [  OK  ]
[root@varunHome]#

The folks who are using windows

Open Console/Command line --> Go to your Jenkins installation directory. Execute the following commands respectively:

To stop:
jenkins.exe stop

To start:
jenkins.exe start

To restart:
jenkins.exe restart
