Jenkins on CentOS 8: How to Automate Your Software Development Process



Why use apt and not apt-get or another command?The apt command has been available since 2014.It has a command structure that is similar to apt-get but was created to be a more pleasant experience for typical users.Simple software management tasks like install, search and remove are easier with apt.


If you are running Jenkins in Docker using the official jenkins/jenkins image you can use sudo docker exec $CONTAINER_ID or CONTAINER_NAME cat /var/jenkins_home/secrets/initialAdminPassword to print the password in the console without having to exec into the container.




How to Install Jenkins on CentOS 8



For Jenkins to function, you need to install either Java JRE 8 or Java 11. In the example below, we decided to go with the installation of Java 11. Therefore, to install Java 11, run the command.


That was a step-by-step procedure of how to install Jenkins Continuous Integration tool on CentOS 8. To learn more about Jenkins. Read Jenkins Documentation. Your feedback on this guide is most welcome.


Congratulations! You have successfully installed Jenkins on CentOS 8. You can now explore Jenkins and start creating your first software project. Get started with Jenkins on VPS Hosting from Atlantic.Net today!


At this point, Jenkins is installed and configured. Now, open your web browser and access the Jenkins setup wizard using the URL . You should see the Jenkins initial setup password page:


When you access Jenkins for the first time (after installation) it will ask you for the password. And to know the password run the below command, and you will see a 32-character alphanumeric password.


Jenkins is an opensource tool which helps to DevOps to run their software development which relates to their Testing, Building and Deployment. Jenkins is server based mechanism which can be run on Nginx, Apache, IIS etc. Today in this post, I am going to show you how to install and configure Jenkins using Nginx on CentOS 8 Operating system step by step in a very simple and clear way


NGINX is a web server that provides whole functionality and easy to configure. Primary thing that we are going to use NGINX explorer to make proxy the connection port 8080 which will work for us over http port 80 connection, install NGINX with following command


In this post and video tutorial we have learned how can we install Jenkins on CentOS 8 using Nginx. I just showed some commands step by step which made this post very easy to understand for visitors. Comment below or contact me directly if you have any doubts/queries related to this post, I will definitely revert with a solution ?


This article will guide you through the process of installing Jenkins on a Vultr CentOS 7 server instance. In order to facilitate visitors' access, Nginx will also be installed as the reverse proxy for Jenkins.


To use this repository, run the following command: sudo wget -O /etc/yum.repos.d/jenkins.repo -stable/jenkins.repo sudo rpm --import -stable/jenkins.io.key If you've previously imported the key from Jenkins, the rpm --import will fail because you already have a key. Please ignore that and move on. yum install fontconfig java-11-openjdk yum install jenkins The rpm packages were signed using this key:

For the purpose of offline installation, RPM packages for jenkins are available at You can also download specific versions of Jenkins from the repository. Once you have downloaded the requisite rpm version, you can install it using:


This step is not required, if you have performed previous step already. If you are using WAR file to install jenkins, you would not be able to configure it as a service. The location to download WAR files is -stable. Thereafter you can run jenkins using:


To install plugins in offline mode, you have to download the respetive .hpi plugin file from -ci.org/download/plugins/. However, if you go this route, you will have to download the dependencies too, which can make this task near impossible. The easier way is to:1. Install Jenkins and the related plugins on your workstation, or any other machine (It can be Windows machine too).2. Once all the plugins are downloaded, you can copy the plugins folder from the workstation to the Jenkins server /var/lib/jenkins folder.3. After you copy, just stop and start Jenkins, and you will see that all your plugins are installed.


Hi, I tried to follow the steps shared by you, but even after starting jenkins service, I am not able to see any contents in /var/lib/jenkins.Also copied the plugins folder directly into /var/ib/jenkins location but I am not seeing in the installed plugins. Can you let us know what could be the issue?


The following tutorial will guide you through installing Jenkins on Ubuntu 18.04. The version of Jenkins available at the time of writing this tutorial required Java 8. I show you how to add the official Java repository to simplify installation and updates.


To use this repository, run the following command: sudo wget -O /etc/yum.repos.d/jenkins.repo sudo rpm --import If you've previously imported the key from Jenkins, the rpm --import will fail because you already have a key. Please ignore that and move on. yum install fontconfig java-11-openjdk yum install jenkins The rpm packages were signed using this key:


To use this repository, run the following command: WARNING: The gpg key use to sign our packages has been updated on 16th of April 2020, therefore you need to reimport it if you imported before this date. sudo wget -O /etc/yum.repos.d/jenkins.repo -stable/jenkins.repo sudo rpm --import -stable/jenkins.io.key If you've previously imported the key from Jenkins, the rpm --import will fail because you already have a key. Please ignore that and move on. yum install jenkins The rpm packages were signed using this key:


  • You will need to explicitly install a Java runtime environment, because Oracle's Java RPMs are incorrect and fail to register as providing a java dependency. Thus, adding an explicit dependency requirement on Java would force installation of the OpenJDK JVM. 2.164 (2019-02) and newer: Java 8 or Java 11

  • 2.54 (2017-04) and newer: Java 8

  • 1.612 (2015-05) and newer: Java 7

With that set up, the Jenkins package can be installed with: See the installation guide for more information, including how Jenkins is run and where the configuration is stored, etc.


We can install new software on Red Hat/CentOS Linux with yum install packagename command from console. Running this command first checks for existing YUM Repository configuration files in /etc/yum.repos.d/ directory. It reads each YUM Repository configuration file to get the information required to download and install new software, resolves software dependencies and installs the required RPM package files.


The error message on the Jenkins dashboard should now have disappeared. At this point we have a working Jenkins installation, accessible via port 80, which will form the basis for some future posts where I have a more detailed look at Jenkins.


Daemonize doesn't ship in the default repository thats why yum is not able to resolve it. You will need to install the Daemonize from the Epel repository which is the extra package for enterprise linux as


Upon completion of the installation process, you will be prompted to create the First Admin user. You can opt to ignore and continue as Admin or create a new Admin user. For now, We are going to create the user.


Standard repositories might not provide all the packages that can be installed on CentOS, RHEL, or Amazon Linux-based distribution. Turning on the EPEL repository provides additional options for package installation.


As Jenkins is written in Java, thus we need a Java development kit installed on our AlmaLinux or Rocky. Here will install the OpenJDK version that is available in the official repo of our Linux. You can go for an older version as well if you want.


The next, thing is to add the source from where we will receive the Jenkins packages and updates to install. For that, we need to add the official RPM repo of Jenkins on our Linux using the below commands:


Although after installing and running this automation server services, we can access its web interface from a locally installed browser, however, if you are using a CLI server then we have to use a remote system browser to access it. For that, the ports must be opened in the AlmaLinux firewall.


Before installing Jenkins on Debian or Debian based distros such as Ubuntu, make sure that you have Java installed first. Jenkins requires to have Java installed and it runs on Java version 8 minimum. To install Java, you can do this with these commands: 2ff7e9595c
