How to install Jenkins on Windows Server

Arjun JS , ,

Installing Jenkins on a Windows server is straightforward. Here are the step-by-step instructions:

Prerequisites:

  • A Windows Server machine (Windows Server 2012 or later).
  • Administrator privileges on the server.
  • Java Runtime Environment (JRE) or Java Development Kit (JDK) installed. Jenkins requires Java.

Steps:

1. Download Jenkins:

  • Visit the official Jenkins website to download the Windows installer: https://www.jenkins.io/download/
  • Scroll down to the “Windows” section and click on the “Windows Installer (64-bit)” link to download the installer appropriate for your system.

2. Run the Installer:

  • Locate the downloaded installer file (e.g., jenkins.msi) and double-click it to run the installer.

3. Install Jenkins:

  • The Jenkins installation wizard will appear.
  • Follow these steps:
  • a. Click “Next” on the welcome screen.
  • b. Choose the installation directory (the default is usually fine) and click “Next.”
  • c. If prompted to choose the type of installation, select “Install as a service” and click “Next.” This option will install Jenkins as a Windows service, which is recommended for production use.
  • d. Set up the port for Jenkins. The default port is 8080, but you can change it if needed. Click “Next.”
  • e. Choose whether or not to install suggested plugins. It’s recommended to install them, so select “Install suggested plugins” and click “Next.”
  • f. Create an admin user by entering a username and password. Take note of these credentials; you’ll need them to log in to Jenkins. Click “Next.”
  • g. Jenkins will now complete the installation. Once it’s finished, click “Finish.”

4. Start Jenkins:

  • Jenkins will start as a Windows service. To access the Jenkins web interface, open a web browser and go to http://localhost:8080 (or the custom port you specified during installation).

5. Unlock Jenkins:

  • To unlock Jenkins, open a command prompt and navigate to the Jenkins installation directory (usually C:\Program Files\Jenkins). Look for a file called secrets\initialAdminPassword.
   cd "C:\Program Files\Jenkins"
   more secrets\initialAdminPassword
  • Copy the displayed password and paste it into the Jenkins web interface to unlock Jenkins.

6. Customize and Use Jenkins:

  • Follow the on-screen instructions to customize Jenkins, including installing additional plugins and configuring the system according to your needs.

7. Start Using Jenkins:

  • After completing the setup, you can start creating Jenkins jobs and pipelines to automate your CI/CD processes.

That’s it! You’ve successfully installed Jenkins on your Windows Server machine. You can now use Jenkins to automate your software development processes.
