Jenkins is an open-source automation server that is used primarily for continuous integration (CI) and continuous delivery (CD) pipelines. It helps automate the building, testing, and deployment of software applications

# **Prerequisites**

Minimum hardware requirements:

* 256 MB of RAM
    
* 1 GB of drive space (although 10 GB is a recommended minimum if running Jenkins as a Docker container)
    

Recommended hardware configuration for a small team:

* 4 GB+ of RAM
    
* 50 GB+ of drive space
    

# **Step 1 :- Installation of Java**

Jenkins requires Java to run, yet not all Linux distributions include Java by default. Update the Debian apt repositories, install OpenJDK 17, and check the installation with the commands:

```plaintext
sudo apt update
sudo apt install fontconfig openjdk-17-jre
java -version
openjdk version "17.0.8" 2023-07-18
OpenJDK Runtime Environment (build 17.0.8+7-Debian-1deb12u1)
OpenJDK 64-Bit Server VM (build 17.0.8+7-Debian-1deb12u1, mixed mode, sharing)
```

# **Step 2:-Installation of Jenkins**

```plaintext
sudo wget -O /usr/share/keyrings/jenkins-keyring.asc \
  https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key
echo "deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc]" \
  https://pkg.jenkins.io/debian-stable binary/ | sudo tee \
  /etc/apt/sources.list.d/jenkins.list > /dev/null
sudo apt-get update
sudo apt-get install jenkins
```

# **Start Jenkins**

You can enable the Jenkins service to start at boot with the command:

```plaintext
sudo systemctl enable jenkins
```

You can start the Jenkins service with the command:

```plaintext
sudo systemctl start jenkins
```

You can check the status of the Jenkins service using the command:

```plaintext
sudo systemctl status jenkins
```

If everything has been set up correctly, you should see an output like this:
