How To Install Jenkins on Ubuntu 20.04 / Ubuntu 18.04

Jenkins is an open-source automation server that helps to automate the repetitive tasks involved in the software development process, which includes building, testing, and deployments.

Here, we will see how to install Jenkins on Ubuntu 20.04 / Ubuntu 18.04.

Install Jenkins On Ubuntu 20.04

Install Java

Since Jenkins is written in Java, it requires Java 8 or Java 11 to run. Here, I will install the OpenJDK 11 for Jenkins installation.

sudo apt update

sudo apt install -y default-jre apt-transport-https wget

If you want to use the Oracle Java in place of OpenJDK, then use any one of the links to install it.

Verify the Java version after the installation.

java -version

OpenJDK 64-Bit Server VM (build 11.0.8+10-post-Ubuntu-0ubuntu120.04, mixed mode, sharing)

Add Jenkins Repository

Jenkins provides an official repository for its packages. To use the Jenkins repository, first, we will need to add the Jenkins public key to the system.

wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add -

Then, add the Jenkins repository to your system.

echo "deb https://pkg.jenkins.io/debian-stable binary/" | sudo tee /etc/apt/sources.list.d/jenkins.list

Install Jenkins

Install Jenkins package using the apt command.

sudo apt update

sudo apt install -y jenkins

The Jenkins service should now be up and running. You can check the status of the Jenkins service using the below command.

sudo systemctl status jenkins
