• Once Jenkins is installed, Job Import plugin will be displayed in the menu.

• Next to import the jobs from another Jenkins URL, click on Job Import plugin

• Once we click on Query!, Jenkins job will be displayed from the remote Jenkins.

• Select jobs to be imported and click on import.

• Jobs will be imported once user clicks on Import.

How to run Jenkins on port other than 8080

By default Jenkins start at port 8080, but at times port 8080 is already used by some other application. We can run Jenkins on port other than 8080 by following below steps:

• In case jenkins is running through command prompt, we can start jenkins to run at port 9090 or any other port using below command:

java -jar jenkins.war --httpPort=9090

• To change the port permanently, follow below steps:

• Go to jenkins home folder. The jenkins home folder is usually at C:\Program Files (x86)\Jenkins in case jenkins is installed from microsoft installer (MSI) file or it can be c:\Users\<UserName>\.jenkins folder.

• Open the jenkins.xml file.

• Change the port number in the file to the required port number.

• Save the file.

• Restart the window service for jenkins.

Install Jenkins as a Windows service

Once we have installed the jenkins setup, we need to launch jenkins.war file manually before accessing jenkins as shown below. To avoid running jenkins.war manually to start jenkins, we can install jenkins as a window service.

Steps to install Jenkins as window service:

1. From the localhost jenkins machine, run the jenkins.war files as shown above.

2. Once Jenkins is up and running, open localhost:8080 in the browser.

3. Go to Manage Jenkins> Install as Windows Service.

4. Follow steps in below screenshot to install Window Service.

5. Go to run>services.msc. Jenkins should be installed as a service.
