If you're a developer, you know that Jenkins is an essential tool for your workflow. Jenkins is a continuous integration (CI) server that helps you automate the build, test, and deploy process of your software projects. Jenkins download takes care of all the tedious and time-consuming tasks involved in development so you can focus on writing code.
If you are in the process of automating your software development or you are looking for a way to optimize your current practices, you can download Jenkins on Windows, macOS, Linux, as well as Docker. Here, we will take you through the steps to get Jenkins up and running on your system. We also get you the requirements for installing Jenkins and configuring it for your own projects.
Jenkins is an open-source automation server written in Java. It is a powerful tool that provides you with numerous benefits including:
In a nutshell, Jenkins provides an easy way to set up a continuous integration or continuous delivery (CI/CD) pipeline. Jenkins certification will make you an expert in utilizing Jenkins for software delivery. This brings numerous benefits such as reduced risks and faster software delivery.
Downloading Jenkins is as simple as a few clicks. However, before you download Jenkins, it is important to consider some crucial factors in Jenkins documentation;
Jenkins offers two different types of releases: stable (LTS) and regular. It is important to understand the difference between the two before you download Jenkins:
If you're looking for a stable, well-supported version of Jenkins, go with the Jenkins LTS download release. If you need the latest features and don't mind dealing with potential bugs, go with a regular release.
Before you download Jenkins, it is important to understand the prerequisites. It will ensure that Jenkins runs smoothly on your system:
While Jenkins is a powerful tool, it can be challenging to download and set up. You need to first download it, and then unlock it. Fortunately, once you know the steps, the process is relatively straightforward. Let’s take a look;
Missing a step in Jenkins download can lead to problems installing it. To avoid any problem, follow all the steps as instructed:
Launch the CMD and login as a sudo/root user and update the system by the following command:
Sudo dnf update - y
After that, you must paste the following command:
sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
Now, install Jenkins by using the next command:
yum install fontconfig java-11-openjdk yum install jenkins
Once installed, you will need to start Jenkins by using the following command:
Sudo system ctl start jenkins
Launch the CMD process and use the below command and hit Enter:
docker run -p 8080:8080 -p 50000:50000 --restart=on-failure jenkins/jenkins:lts-jdk11
at /var/jenkins_home/secrets/initialadminpassword or you can copy the code that appears on your system.
Now, you can use the Local host to unlock Jenkins by providing the password that you received recently.
After you install Jenkins on your system, it is necessary to start its configuration for its proper use. To do this, follow the below instructions:
As soon as you finish installing Jenkins on your system, you must open your web browser and search http://localhost:8080 or http://localhost:8090 based on your port selection.
Once you visit the local host, you’ll be asked for credentials. If you’re a Windows user, you’ll get the administrator password under the installation path of Jenkins. The default one is C:\Program Files (x86)\Jenkins. However, it also varies on what directory you chose during its installation.
Once you reach there, look for the InitialAdminPassword file and open it to copy the code. Now paste the code into the pop-up tab prompting for password and choose Continue to unlock Jenkins successfully.
Mac users will get the location of the password on their screen. It is generally, /Users/Shared/Jenkins/Home/Secrets/Initialadminpassword. However, it can also vary if you chose a different installation folder.
Linux users can enter sudo cat /var/lib/Jenkins/secrets/initialadminpassword and they will get the password.
Docker users will get the password on their CMD screen after they finish the installation of Jenkins. Also, they can reach /var/jenkins_home/secrets/initialadminpassword to copy the password.
Customizing Jenkins allows you to optimize your build pipeline for specific environment. It leads to faster builds and when combined with DevOps certification, the opportunities for your growth are doubled. Here’s how you can customize Jenkins:
Unless you have a good reason to change it, leave it as it is so as to avoid any confusion later on. If another application is already using port 8080, you can simply choose another port and you are all set! Now, you are ready to create some Jenkins Jobs.

When you download a file from the Jenkins server, it is important to verify the authenticity of the file before opening it. One way to do this is to use jarsigner, a tool that is included with the Java Development Kit (JDK).
To use jarsigner, you first need to locate the file that you downloaded from Jenkins. If the file is compressed, you will need to uncompress it first. Once you have located the file, open a command prompt and navigate to the directory where the file is located.
At the command prompt, type "jarsigner -verify -verbose [filename]" and press Enter. This will display information about the file, including whether or not it has been signed by a trusted source.
If you see "jar verified" followed by a certificate chain, then you can be confident that the file is safe to open. If you do not see this message, or if you see an error message instead, then the download package may have been tampered with and should not be opened.
When you perform the Jenkins download from its official website, the installer file is signed with a digital signature. This signature helps verify the file's integrity and authenticity. You can use the signtool utility to verify the digital signature of the file.
The signtool utility is included in the Windows SDK. To use signtool, you must first install the Windows SDK on your computer. Then, open a command prompt and navigate to the folder where the Jenkins installer file is located.
Run the following command: signtool verify /v jenkins.msi. This will display information about the digital signature, including the signer's identity and the date and time when the file was signed.
If the signature is valid, you will see a message indicating that "Signature verification succeeded." Otherwise, you will see an error message indicating that the signature is invalid. Either way, you can be confident that the file you downloaded has not been tampered with and is safe to install.
For Linux users, the most common way to do this is by using a Package Manager like apt or yum. These tools will check the digital signatures of the files you're downloading against a known good key, ensuring that the files have not been tampered with.
You can also verify Jenkins downloads by checking the GPG signature. The Jenkins project provides a signing key that you can use to verify the authenticity of your download. Simply run the 'gpg' command against the downloaded file, and you’ll have a detailed report showing whether or not the file has been altered.
One of the great things about Jenkins is that you can install Jenkins on AWS, Azure, and Google Cloud Platforms like public clouds. There are two main ways to deploy Jenkins in a public cloud: using a managed service or using a self-managed virtual machine.
If you choose to use a managed service, then the cloud provider will take care of provisioning and managing the underlying infrastructure for you. This can be a great option if you don't want to deal with the complexities of setting up and maintaining your own Jenkins server. However, it can also be more expensive than running your own server.
If you choose Jenkins deployment on your own server, then you will need to provision and configure a virtual machine in the public cloud. This option gives you more control over the server, but it also requires more work to set up and maintain. Once you have provisioned your virtual machine, you can follow the official instructions for installing Jenkins.
Once Jenkins is up and running, you will need to configure it in order to allow access from the outside world. This can be done by setting up a reverse proxy or by using a tool such as ngrok. Once your instance is properly configured, you should be able to access Jenkins cloud from anywhere in the world.
