Jenkins is an automated build tool that can run in Linux systems and can help users realize automated build, test and deployment processes. This article will share how to use Jenkins automated build tool under Linux system.

  1. Installing Jenkins

Installing Jenkins on a Linux system is very simple, just execute the following command:

sudo apt-get update
sudo apt-get install jenkins

After installing Jenkins, you can Enter "http://localhost:8080" in the browser to open the Jenkins home page.

  1. Create a Jenkins Job

Now you need to create a new Jenkins Job so that Jenkins can automate your build process. To create a new Job, you can follow the steps below:

  • In the Jenkins home page, click New item in the left sidebar.
  • Enter the name of the Job, select Free Form Build, and click the "OK" button.
  • Under the Build Triggers option, select the Build Multiple SCMs option and configure your source code repository details.
  • Under the "Build Steps" option, you can choose to compile the code, run test cases and other operations.
  • Finally, save and submit your Jenkins Job.

Now, you can see the new Job you created on the Jenkins home page, and click the Job to run the automated build tool.

  1. Configuring Jenkins plug-ins

Before using the Jenkins automated build tool, you need to install and configure some necessary plug-ins to ensure that Jenkins can run correctly. Normally, Jenkins will install some common plug-ins by default, but you can also install them manually. The specific steps are as follows:

  • In the Jenkins homepage, click the "Manage Jenkins" button.
  • Select the "Plug-in Management" option.
  • Search for the name of the plug-in you need to install in the optional plug-in list and click the "Install" button.

If you cannot find the plug-in you need, you can try to search for related plug-ins on the Jenkins official website. After installing the plug-in, you need to restart Jenkins for it to take effect.

  1. Set Jenkins environment variables

When executing automated build tools, Jenkins needs to use some environment variables to call your build scripts and other tools. Therefore, before using Jenkins, you need to ensure that all necessary environment variables are set. Generally speaking, these environment variables can be set in the global configuration of Jenkins.

To set environment variables, follow these steps:

  • In the Jenkins home page, click the Manage Jenkins button.
  • Select the "Configure System" option.
  • In the "Global Properties" section, click the "Environment Variables" button.
  • Here you can configure the required environment variables and click the save button.
  1. Using Jenkins CLI

Jenkins CLI is a tool that can run Jenkins from the command line. Using the Jenkins CLI, you can perform certain operations such as building a new Job, listing all Jobs, and more. To use the Jenkins CLI, follow these steps:

  • Download the Jenkins CLI, you can find the download link for the CLI in the "User Documentation" link on the Jenkins home page.
  • Extract the CLI file and add it to your PATH environment variable.
  • Run the "jenkins-cli help" command on the command line to view the help information of the CLI tool.
  1. Using Jenkins Pipeline

Jenkins Pipeline is a DSL through which you can write the build process in a Jenkinsfile. Using Jenkins Pipeline, you can better manage and control your build process, thereby improving overall build quality and maximizing build speed. In order to use Jenkins Pipeline, please follow the steps below:

  • In the Jenkins home page, click the "New Item" button in the left sidebar.
  • In the new item interface, select the "Multi-branch Pipeline" option.
  • Enter the name of Jenkins Pipeline and configuration source file and other information, and save its configuration.

Now, you can see the Jenkins Pipeline you created on the Jenkins homepage. Click the Pipeline to start the automated build work.

Summary

Jenkins on Linux systems has excellent automated build capabilities and can integrate a variety of open source tools to optimize the build process. This article introduces how to use the Jenkins automated build tool in Linux, including creating a Jenkins Job, configuring the Jenkins plug-in, setting environment variables, using the Jenkins CLI and other aspects. Through these methods, you can improve the running efficiency and build quality of Jenkins, thereby bringing more value to your project.
