How To Install Jenkins on CentOS 7

Install Jenkins on CentOS 7

In this tutorial, we will show you how to install Jenkins on CentOS 7. For those of you who didn’t know, Jenkins is an open-source continuous integration tool written in Java. Jenkins provides continuous integration services for software development. It is a server-based system running in a servlet container such as Apache Tomcat. It supports SCM tools including AccuRev, CVS, Subversion, Git, Mercurial, Perforce, Clearcase, and RTC, and can execute Apache Ant and Apache Maven-based projects as well as arbitrary shell scripts and Windows batch commands.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you the step-by-step installation of Jenkins on CentOS 7.


  • A server running one of the following operating systems: CentOS 7.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Jenkins on CentOS 7

Step 1. First of all, we have to install Java JDK.

Installing Java using the following command:

yum install java-1.7.0-openjdk wget

Step 2. Install Apache webserver.

Installing Apache using the following command below:

yum install httpd

Step 3. Add Jenkins repository packages.

sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo
sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key

Step 4. Install Jenkins on CentOS 7.

yum install jenkins

Step 5. Configure firewall.

sudo firewall-cmd --zone=public --add-port=8080/tcp --permanent
sudo firewall-cmd --reload

Step 6. Start Jenkins service.

sudo /etc/init.d/jenkins restart
