1.2 Jenkins Installation
Jenkins can be installed on a variety of platforms, including Windows, macOS, and Linux. Here are the steps to install Jenkins on a Linux machine:
1.2.1 Install Java
Jenkins requires Java to be installed on your machine. If you don’t have Java installed, you can install it by running the following command in your terminal:
Command
sudo apt-get install openjdk-8-jdk
This will install OpenJDK 8, which is the recommended version for Jenkins.
1.2.2 Add Jenkins repository
Next, you need to add the Jenkins repository to your system’s package manager. Run the following commands in your terminal:
Commands
wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add - sudo sh -c 'echo deb https://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'
This will add the Jenkins repository to your system.
1.2.3 Update package list
Next, update the package list by running the following command:
Command
sudo apt-get update
This will ensure that your system is aware of the latest packages available.
1.2.4 Install Jenkins
Now you can install Jenkins by running the following command:
Command
sudo apt-get install jenkins
This will download and install Jenkins on your system. During the installation process, you will be prompted to choose whether or not to install additional packages. You can choose to install them if you wish or skip them if you don’t need them.
1.2.5 Start Jenkins
Once Jenkins is installed, you can start it by running the following command:
Command
sudo systemctl start jenkins
This will start the Jenkins service. You can check the status of the service by running the following command:
Command
sudo systemctl status jenkins
This should display the status of the Jenkins service and confirm that it is running.
1.2.6 Access Jenkins
Finally, you can access Jenkins by opening your web browser and navigating to http://localhost:8080. This should bring up the Jenkins login page. The first time you access Jenkins, you will be asked to enter an initial admin password, which can be found in the following file:
File location
/var/lib/jenkins/secrets/initialAdminPassword
Once you have entered the password, you will be asked to customize your Jenkins installation by selecting the plugins you want to install. You can either select the suggested plugins or choose your own set of plugins. After the plugins are installed, Jenkins will be ready to use. In conclusion, installing Jenkins is a straightforward process that can be completed in just a few steps. By following the steps outlined above, you can quickly set up Jenkins on your machine and start using it for your software development projects.
1.3 Jenkins Configuration process
Once you have installed Jenkins, you will need to configure it to suit your needs. Jenkins has a wide range of configuration options that can be customized to your specific requirements. Here are some of the key configuration options that you may want to consider:
- Security Configuration: Jenkins allows you to configure security settings to protect your installation. You can configure access control, user authentication, and authorization. This can be done by navigating to the “Manage Jenkins” page and selecting “Configure Global Security”. You can then choose the authentication method, configure user permissions, and set up access control
- Plugin Configuration: Jenkins has a large number of plugins that can be used to extend its functionality. You can install and configure plugins from the “Manage Plugins” page. This page allows you to browse the available plugins, install new plugins, and update existing ones. Once you have installed a plugin, you can configure it from the “Configure System” page
- Node Configuration: Jenkins allows you to configure nodes, which are individual machines or virtual machines that can be used to run build jobs. You can add nodes by navigating to the “Manage Nodes” page and selecting “New Node”. You can then configure the node settings, including the name, labels, and remote root directory
- Build Configuration: Jenkins allows you to configure build jobs, which are the tasks that automate the building, testing, and deployment of your software. You can create a new job by navigating to the “New Item” page and selecting “Freestyle project”. You can then configure the job settings, including the source code repository, build triggers, build steps, and post-build actions
- Email Notification Configuration: Jenkins can be configured to send email notifications when build jobs succeed or fail. You can configure email notifications by navigating to the “Manage Jenkins” page and selecting “Configure System”. You can then enter the email server settings and configure the email notification settings for each job
In conclusion, configuring Jenkins is an important step in setting up your software development environment. By customizing the security settings, plugins, nodes, build jobs, and email notifications, you can create a powerful and flexible automation platform that can streamline your software development process. That is all for this tutorial and I hope the article served you with whatever you were looking for. Happy Learning and do not forget to share!
