How to restart Jenkins manually?

Answer 1

If you want to just reload the configuration file, one can do

    <jenkins_url>/reload

This is quicker if you have made some small change in the configuration file, like config.xml directly in the file system or made copies of the job through the filesystem (not through the browser).

Answer 2

It depends on how Jenkins has been started.

• As a service: sudo service jenkins restart, sudo /etc/init.d/jenkins restart, etc.

• As a web application in a Tomcat installation: restart your Tomcat, or just restart the application in Tomcat. Go to http://<tomcat-server>:8080/manager/list or after authentication hit http://<tomcat-server>:8080/manager/stop?path=/myapp+ http://<tomcat-server>:8080/manager/start?path=/myapp.

• Launched with just java -jar: kill it (kill -9 <pid>), and relaunch it.

• Launched with java -jar, but from a supervisor: supervisorctl restart jenkins

Answer 3

For restarting Jenkins manually using the browser:

Enter your www.jenkins-ip/restart (for example, http://localhost:8080/restart) in the browser. Jenkins will restart and load the login page automatically after restart.

Answer 4

You have many options to restart Jenkins manually, but mainly two (URL or command line):

• Alternative 1: Using the Jenkins installation URL:

  Jenkins_URL/restart.

  Example: http://jenkinsserver.com/restart

  This type of restart forces a restart without waiting for builds to complete.

  If you need to wait for the jobs endings you can use:

  Jenkins_URL/safeRestart.

  Example: http://jenkinsserver.com/safeRestart

• Alternative 2: Using the command line, depending on your Jenkins installation.

  • If you're installing using rpm or deb package or you have the Jenkins installation in Red Hat, Ubuntu, or Debian, you can use these commands:

  • sudo service jenkins restart

    This restart Jenkins in one step.

  • sudo service jenkins stop and sudo service jenkins start,

    This restart Jenkins in two steeps.

    Note: if you need to check the Jenkins status, you can use this command: sudo service jenkins status

  • If you are using CentOS, you can use this command:

    sudo systemctl restart jenkins
    

    Note: if you need to check the Jenkins status, you can use this command: sudo systemctl status Jenkins

Answer 5

If you are able to access it in a web browser, just add /restart, for example, localhost:8080/restart.

If you are running it as a service then log in to your server and execute the command:

sudo service jenkins stop/start

Answer 6

Try the below. It worked for me.

sudo service jenkins status  

It will give you PID of Jenkins. Now do a

kill -15 [PID]

sudo service jenkins start
