Jenkins linux

Jenkins is a popular open-source automation server that is used to build, test, and deploy software projects. It is platform-independent, meaning it can be installed on various operating systems, including Linux.

To install Jenkins on Linux, you can follow these general steps:

1. Update your package lists:

   sudo apt update

2. Install Java Development Kit (JDK) if it is not already installed. Jenkins requires Java 8 or later versions.
For example, on Ubuntu:

   sudo apt install openjdk-11-jdk

3. Add the Jenkins repository key to your system:

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

4. Add the Jenkins repository address to your package sources:

   sudo sh -c 'echo deb http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'

5. Update your package lists again:

   sudo apt update

6. Install Jenkins:

   sudo apt install jenkins

7. Start the Jenkins service:

   sudo systemctl start jenkins

Once Jenkins is running, you can access its web interface by opening your browser and navigating to `http://localhost:8080` (if you installed it on the same machine) or `http://<your-server-ip>:8080` (if you installed it on a remote machine).

You will be prompted to unlock Jenkins by providing an initial admin password. You can find this password in the following file:

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

Follow the instructions on the web interface to complete the Jenkins setup.

Please note that these steps are for Debian/Ubuntu-based Linux distributions. The installation process may vary slightly for other Linux distributions.
