Installing Jenkins

CI/CD Jenkins
#1

Hello everyone,
I tried installing jenkins by following the process below but cannot get jenkins to install:

sudo wget -O /etc/yum.repos.d/jenkins.repo
https://pkg.jenkins.io/redhat-stable/jenkins.repo
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io-2023.key
sudo yum upgrade

Add required dependencies for the jenkins package

sudo yum install fontconfig java-17-openjdk
sudo yum install jenkins
sudo systemctl daemon-reload

I’m getting the following error:

You use sudo to run commands as root, for example:

sudo apt update

Or you can open a shell as root using:

sudo -i

You do not need to run sudo apt update, I was just giving an example of how you use sudo.

When you want to ssh to the other host you just run this:

ssh root@jenkins
