Point:1

Download jenkins from this link:
https://www.jenkins.io/download/#downloading-jenkins

Point:2

Installation steps using Windows MSI installer

Refer to the step:1 page to download either an LTS release or a weekly release of the Windows installer. After the download completes, open the Windows installer and follow the steps below to install Jenkins.

Step 1: Setup wizard: On opening the Windows Installer, an Installation Setup Wizard appears, Click Next on the Setup Wizard to start your installation.

Windows Installation Setup Wizard

Step 2: Select destination folder: Select the destination folder to store your Jenkins Installation and click Next to continue.

Jenkins Installation Destination


Step 3: Service logon credentials: When Installing Jenkins, it is recommended to install and run Jenkins as an independent windows service using a local or domain user as it is much safer than running Jenkins using LocalSystem(Windows equivalent of root) which will grant Jenkins full access to your machine and services.

To run Jenkins service using a local or domain user, specify the domain user name and password with which you want to run Jenkins, click on Test Credentials to test your domain credentials and click on Next.

Jenkins Service Logon Credentials

If you get Invalid Logon Error pop-up while trying to test your credentials, follow the steps explained here to resolve it.


Step 4: Port selection: Specify the port on which Jenkins will be running, Test Port button to validate whether the specified port if free on your machine or not. Consequently, if the port is free, it will show a green tick mark as shown below, then click on Next.

Jenkins Select Port


Step 5: Select Java home directory: The installation process checks for Java on your machine and prefills the dialog with the Java home directory. If the needed Java version is not installed on your machine, you will be prompted to install it.

Once your Java home directory has been selected, click on Next to continue.

Select Java Home Directory

Step 7: Install Jenkins
: Click on the Install button to start the installation of Jenkins.

Windows Install Jenkins

Additionally, clicking on the Install button will show the progress bar of installation, as shown below:

Windows Installation Progress

Step 8: Finish Jenkins installation: Once the installation completes, click on Finish to complete the installation.

Jenkins will be installed as a Windows Service. You can validate this by browsing the services section, as shown below:

Windows Jenkins Service

See the upgrade steps when you upgrade to a new release.

Post-installation setup wizard

After downloading, installing and running Jenkins, the post-installation setup wizard begins.

This setup wizard takes you through a few quick "one-off" steps to unlock Jenkins, customize it with plugins and create the first administrator user through which you can continue accessing Jenkins.

Unlocking Jenkins

When you first access a new Jenkins instance, you are asked to unlock it using an automatically-generated password.

Step 1: Browse to http://localhost:8080 (or whichever port you configured for Jenkins when installing it) and wait until the Unlock Jenkins page appears.

Unlock Jenkins page

Step 2: The initial Administrator password should be found under the Jenkins installation path (set at Step 2 in Jenkins Installation).

For default installation location to C:\Program Files\Jenkins, a file called initialAdminPassword can be found under C:\Program Files\Jenkins\secrets.

However, If a custom path for Jenkins installation was selected, then you should check that location for initialAdminPassword file.

Step 4

On the Unlock Jenkins page, paste this password into the Administrator password field and click Continue.
Notes:

You can also access Jenkins logs in the jenkins.err.log file in your Jenkins directory specified during the installation.
The Jenkins log file is another location (in the Jenkins home directory) where the initial password can also be obtained. This password must be entered in the setup wizard on new Jenkins installations before you can access Jenkins’s main UI. This password also serves as the default admininstrator account’s password (with username "admin") if you happen to skip the subsequent user-creation step in the setup wizard.

What is Jenkins pipeline? How to Create pipeline script in groovy?

Click Here : DevOps Related Posts

How to send email notification with groovy script in Jenkins pipeline?

Pipeline Script Fundamentals

Pipeline concepts

The following concepts are key aspects of Jenkins Pipeline, which tie in closely to Pipeline syntax (see the overview below).

Pipeline

A Pipeline is a user-defined model of a CD pipeline. A Pipeline’s code defines your entire build process, which typically includes stages for building an application, testing it and then delivering it.

Also, a pipeline block is a key part of Declarative Pipeline syntax.

Node

A node is a machine which is part of the Jenkins environment and is capable of executing a Pipeline.

Also, a node block is a key part of Scripted Pipeline syntax.

Stage

A stage block defines a conceptually distinct subset of tasks performed through the entire Pipeline (e.g. "Build", "Test" and "Deploy" stages), which is used by many plugins to visualize or present Jenkins Pipeline status/progress. [6]

Step

A single task. Fundamentally, a step tells Jenkins what to do at a particular point in time (or "step" in the process). For example, to execute the shell command make use the sh step: sh 'make'. When a plugin extends the Pipeline DSL, [1] that typically means the plugin has implemented a new step.

Pipeline syntax overview

The following Pipeline code skeletons illustrate the fundamental differences between Declarative Pipeline syntax and Scripted Pipeline syntax.

Be aware that both stages and steps (above) are common elements of both Declarative and Scripted Pipeline syntax.

Declarative Pipeline fundamentals

In Declarative Pipeline syntax, the pipeline block defines all the work done throughout your entire Pipeline.

Jenkinsfile (Declarative Pipeline)

pipeline {
    agent any 
    stages {
        stage('Build') { 
            steps {
                // 
            }
        }
        stage('Test') { 
            steps {
                // 
            }
        }
        stage('Deploy') { 
            steps {
                // 
            }
        }
    }
}

	Execute this Pipeline or any of its stages, on any available agent.
	Defines the "Build" stage.
	Perform some steps related to the "Build" stage.
	Defines the "Test" stage.
	Perform some steps related to the "Test" stage.
	Defines the "Deploy" stage.
