Step 1: Preparing the Environment for Jenkins

Before you start the process to set up Jenkins on Rocky Linux in VirtualBox, ensure the following:

Rocky Linux is installed on your VirtualBox VM. Need help? Watch our video on how to install Rocky Linux on VirtualBox.
Your system is updated:
```
sudo dnf update -y  
```

Step 2: Installing Java for Jenkins

Jenkins requires Java to run. Follow these steps to install Java:

Install OpenJDK 11, the recommended version for Jenkins:
```
sudo dnf install java-11-openjdk -y  
```
Verify the Java installation:
```
java -version  
```

Step 3: Adding the Jenkins Repository on Rocky Linux

To set up Jenkins on Rocky Linux, we first need to add its official repository:

Install wget:
```
sudo dnf install wget -y  
```

Add the Jenkins repository:

wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo

Import the GPG key:

sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

Step 4: Installing Jenkins on Rocky Linux

After setting up the repository, install Jenkins by running:

Install Jenkins:
```
sudo dnf install jenkins -y  
```

Start and enable Jenkins:

sudo systemctl start jenkins  
sudo systemctl enable jenkins

Step 5: Configuring the Firewall for Jenkins

By default, Jenkins uses port 8080. Open this port to allow access:

Add a firewall rule:

sudo firewall-cmd --permanent --add-port=8080/tcp

Reload the firewall:
```
sudo firewall-cmd --reload  
```

Step 6: Accessing Jenkins on Rocky Linux

Open your web browser and enter the IP address of your VM followed by :8080. Example:
```
http://192.168.1.100:8080  
```

Retrieve the initial admin password:

sudo cat /var/lib/jenkins/secrets/initialAdminPassword

Paste the password into the browser, complete the setup wizard, and install the recommended plugins.
