Install Jenkins on Ubuntu 18

Create a VPS on Digitalocean, AWS or wherever you want.

Since it’s a new machine we want to update the repositories:

sudo apt-get update

Jenkins runs on Java 8, so now we are going to install it:

sudo apt-get install openjdk-8-jdk wget gnupg
sudo sh -c 'echo deb binary/ > /etc/apt/sources.list.d/jenkins.list'
sudo apt-key adv --keyserver --recv-keys 9B7D32F2D50582E6
sudo apt-get update
sudo apt-get install git jenkins

Now we are going to create a SSH key for jenkins. This will allow us to authenticate with Github or other services.


To make sure than Jenkins is running, execute the following command:

service jenkins status
service jenkins start

Jenkins will be running on port 8080. So if you access YOUR_IP:8080 you should see the following screen

Now copy the password that has been created for you:

cat /var/lib/jenkins/secrets/initialAdminPassword

For now we are going to select “Install suggested plugins“. You can uninstall the plugins later.

After the installation, you’ll have to create the first admin user.

On the next screen you’ll have to configure the Jenkins URL. The default is the server IP with the port 8080. You can create a DNS record and user a custom domain or subdomain.
